My 2010 S4 has 9,500 miles on it. Over the weekend I started getting warning messages saying "Gearbox malfunction, you may continue driving. Limited functionality." and sometimes the car had trouble getting going from a stop. It's at the dealer now and they're diagnosing.

Anyone else have experience with this? The searches I did showed some similar issues on A4's that turned out to be some kind of transmission filter that takes 4+ weeks to order. I hope that's not the case here.

The only DSG malfunctions that have been written about on the S4 forums just have to do with a wrong version of software (though weird for that to happen at 9,500 miles). Keep us updated.

The exact same thing happened to my S4 several month ago. My dealer was on day two of installating a new S-tronic transmission in it when they were notified that the original software had a fault that only appeared after several months and 5-10k+ kilometers. So the new gearbox was totally unecessary. This has evidently happened to a number of other NA owners. (Mine has been flawless since.) Your dealer should be well aware of this issue and can download the correct software build/release/version.

Awaiting a new "Multi-tronic" to arrive at the dealer. Once it arrives, they will check if the new part has V1 or V2 of the circuit board and determine how to proceed.

Missing my old manual transmission...

I think they meant to tell you "Mechatronic" - this is the brain that is comprised of small sets of hydrolic valves and actuators which are responsible for the movement of the gears and selection in the DSG.

http://www.myturbodiesel.com/1000q/dsg_faq.htm

Scroll about 60% down the page, they talk about the mechatronics and removal/replacement.

Zed - No real diagnosis, if they plug it in and the DSG says "bad mechatronics" they replace the entire module, sending the bad one back to be cleaned out and rebuilt. The valves and actuators in there are very sensitive, so any sliver of metal or dirt particle can really hose them. This is why pre-B8 S4, the maintenance interval was a very strict 40K miles to replace all the fuild and filter. With ours, it shouldn't need this (according to Audi) as they now have 2 oil loops - one ATF loop that lubes the gear meshes and cools the clutch plates, doing double duty in flitering the metal out of the fluid from mesh wear and tear - then a hypoid oil loop for the mechatronics ONLY to use - removing the chances of the gears shedding metal that the filter misses and hosing the mechatronics.

Indeed, I know I read of another S4 owner in this forum who had the mechatronics replaced, so I thought that's what he meant.

Yes, your's is the 3rd I have knowledge of being replace, in addition to 2 which just needed a software reflash.

Mine was replaced last year at approximately 4500km's. Haven't had a problem since. Might have been a bad batch.

Update: New mechatronic has arrived at the dealer. Apparently it's a newly improved version, and it can come with one of two circuit boards (V1 or V2). It arrived with the V1 circuit board, so now we have to wait a week to get a V2 circuit board from Germany.

DOH!! but good news that you will have the newest rev which should (one would think) work better and correct issues with V1.

What did they give you to drive in the interim?

Well, I started with a Pontiac G5... then "upgraded" to a Hyundai, and the next day the dealer held one of their loaner cars that got returned so I have a new (4k miles) A3 now. Decent car, but hard to get used to the front wheel drive. I think it'll need two new front tires when I'm done with it! :)

Are you sure about that?
My opinion is that common hypoid oil lubes the gears and Torsen diff, just like ordinary MT, and special ATF oil (not Dexron, some kind of an original VAG oil) is for lubricating of clutches and all of the hydraulic cirquits inside S-tronic.

As a reminder - my mechatronic was replaced at 7500 km. 19000 km it is now, no more transmission issues.

Update: It's been at the dealer for 2 weeks now. New mechatronic w/ new circuit board was installed today. They test drove it and got the same fault code as before. Back to the drawing board...

I must say though that Audi of America is quite good about customer service. They called and want to do whatever they can to take care of me. I'm really bummed about my bad luck with new Audis though. My 2000 S4 was the best car ever and I wish I still had it. 2008 S6 lived at the dealer, replacement 2008 S6 spent it's first 2 weeks at the dealer and still was never right... and now this.

Oh wow... so sorry to hear about your bad luck, Seb. Has the new transmission been installed? Hopefully you're back on the road again by now... otherwise the A3 should be on it's 3rd set of front tires?! :-D

Yes, the new transmission is in. I've put about 400 miles on it and it seems to be working fine. I must say that it does perform differently. They say this is a new revision of the S-Tronic. It seems to me that it's been toned down a bit. Before, if I had both transmission and rear diff set to Dynamic, I had tons of fun accelerating into corners and feeling that rear diff whip it around the corner. Now, it seems that the shift program is more conservative and the transmission seems to opt for higher gears more often even in "S" mode. So I no longer get that feeling on the cornering because the transmission is shifting up so much. I know, the solution is to shift it manually... but I do miss the old "S" mode in the original transmission.

Don't forget that with a new transmission the ECU will likey have to relearn your driving style all over again. It may get better over time and be back to where it was.

I got the same issue at 21K miles. Its at the dealer right now, except they went straight to replace the Tranny. I also got some errors about Parking Brake Failure. DId you have that error? How is the car now?

10-08-2011, 11:22 AM
It just had happen to me today. Before the RPM would shoot up like the car was in N in the middle of a gear or the car would hold or lag the gear before shifting. Then today it happen again where I usually let off the gas and problem fixes it self in seconds I continued to give it throttle and the message came up. Will be going in Tuesday sharp to get it looked at.

I'd agree, not a big deal to change out, but still a pain on a new car.

Dealer said the mechatronic had to be replaced. The car is also giving a parking brake error message.
I found it odd they handed me the car back and tOld me it was safe to drive until the new unit arrives.
Can anyone chime in?
Hope everything works out!

Mines was a 2011, my parking brake was acting up the other day it wouldnt apply but it didnt give me an error on it. I aside from the error got dead throttle a few times as well but no error message or anything came up. I would step on it and no response from the car once it was making a left but it only lasted few second.

Mine, a 2010 MY, had same happen last week - which after stopping engine and restarting with no recurrence of problem, I thought it was a once off - but then again twice this weekend.
Dealer wasn't able to conclude initially what needed correction or replacement (just had time to run a scan on ECU, which did throw up error). As problem is not critical - precautionary limp mode warning which reverts to normal mode after clutch temp cools a little - I was likewise also given ok to drive home until they take car in later in the week.

Some other thread detail I picked up on, towards end of the article, explains a little why it's potential for damage is avoided once sent into limp mode. Just hassle of car being away for couple days ; http://www.audizine.com/forum/showthread.php/356141-Details-about-the-Seven-speed-dual-clutch-gearbox-0B5-S-tronic-(DL501)

11/4 : Follow up Prognosis - Mechatronic being replaced. Only 12K Km on meter (ref).

I'm out driving and I get the transmission malfunction safe to drive warning... then it happens five minutes later... and five minutes later the warning comes again and the car goes out of gear and into neutral, it then "catches" and I get home. I have a 2010 S4, with the DSG, 36K miles.

From the collective experience of the community, does it sound like I'm going to need a new transmission? In advance, thanks!

3 year warranty is normal I think - so if you're inside that (just?) then you should be covered.

Since my mechatronic module was replaced no problems have recurred.

It's from oct 2009 so I should be in the "safe zone". I read somewhere(cannot find the url atm) that the extended warranty for stronic is 6years or 100.000km... Can someone acknowledge this?

BTW tnx S4Tokyo!

As I said on Audiworld on your thread on this, if you got a letter from Audi like the US owners did who were hit by both the thermostat and water pump recalls, they sent a letter stating a 100K miles, 6 year warranty on the power train.

BartJanssen
01-05-2012, 07:48 AM
@ NWS4Guy, I'm the second owner of the car so maybe the previous owner got the letter, maybe not. I think it is not a bad idea if the dealer also checks thermostat and water pump status.

Anyway it is good to know that this occurred in the US! If the dealer is giving me a hard time I will most likely need a copy from such a letter. I hope you guys can help me out, if needed...

Thanks!

I had a similar issue before when I was about 10k miles; I was on the highway about 80 mph, and the car just slowed down with no acceleration. I pulled over and restarted the car then it was fine. But the dealership replaced ATF gasket and ATF filter, as this could happened from lack of ATF oil circulation.

I now have the same issue with 49K. This is the fourth time I have suffered a gearbox malfuntion since September and the second time it's been in the shop this week for this issue. The first time this week they did the software update and it worked fine for a day. Then it went into limp mode while I was on the highway yesterday (scary as hell). I'm guessing it's mechatronics now, there can't be much left to do otherwise I imagine, other than replace the whole tranny. [:(]

Sorry to hear that. It is somewhat disappointing ... Look @ it this way ... better to happen @ 49K than at 56K when you are totally out of warranty, although the fact that the dealership can fix permanently the issue after 3 times is outrageous!

Entire tranny needs replacing. They're guessing 8 weeks for the thing to arrive. Now I will have had the entire engine and tranny replaced within a year and a half of ownership. Not looking good.

They did not give you hard time about the exhaust etc right?

They didn't care one bit about the exhaust, but they kept asking me if the engine was tuned because the clutches were running very hot. They said that the engine was making more power than it should be, causing extra load on the DSG. I don't have a tune and told them that they should be able to tell if I did. They then asked how I would know that, and I mentioned the TD1 detection when they scan. They said they scanned the car but still believed I had a tune as the engine was making much more power than it should. I told them to scan it all day long, they won't find anything because there's nothing to find.

Within a couple hours they called back and said they believed me. That was the end of that discussion. Very odd. So either I have a factory freak for an engine or they were just bluffing to try and get me to bite. Either way, I don't have a tune so I'm not too concerned.

Same thing on mine. I didn't get the other errors you did, neither did the car bog down or act weird. The error code went off after about 5 miles. Once I got it back home, started it back up a few times, no error code. Taking it in to elite this morning to scan what code it pulled. It could of either overheated for some weird reason or beginning sign of the mechatronics going bad.

Quick update: just got back from getting it scanned. It was only an electronic error from the gear selector lever sensor. Not really sure what that is but it only happened once. We cleared it hopefully it won't happen again or we might have to replace that sensor. Thank goodness it wasn't the DSG or mechatronic unit.

The mechatronics was replaced on my 2012 S4 around 6K miles. The car has ran for several months, I have 10K now. About 3 weeks ago I was at a light, when to take off and it bogged down to the point that I pulled over with no power, no CEL or codes registered (twice now on dynamic mode), then power comes back like nothing happened without shutting the car off.
I took the car back to the dealer and they contacted TAC support and TAC wanted the dealer to duplicate the issue and check for codes.
Dealer had my car for 5 days and nothing, we shall see what happens in the near future. Anyone else experiencing this multiple times?

I kick myself daily for not buying a manual...

Just talked to the service department. The engine threw faults for "transmission fluid pressure". Anyone seen this before?

They need to test the transmission out with fluids at specific temperatures. They're gonna run those tests and get back to me tomorrow.

Update2: The gearbox malfunction error did pop back up again yesterday (3 times); not only did this error pop up but also got a parking brake error as well. Got to a red light and put it into park, turned the engine off and then went to turn it back on but it wouldn't start - couldn't read that I had the shifter in P or N. Tried this several times and finally got it to start. Took it into the dealership today, so we will see what happens and whether any TD1 flags keeps them from fixing it under warranty. It clearly seems to be some electronic/sensor error with the gear selector lever...

Seems like it is happening to plenty of people that are not tuned so I don't think you should have any problems. Good luck.

Wow seems like allot of people are getting their trannies replaced over there. Same thing happened to me earlier this year with my 2010 with 43.5K miles.

First the Gearbox malfunction light came on, and the car felt sluggish. Stopped the car restarted it, and the error and problem was gone. Further down the road, same error popped up with the R crossed out and I lost the use of the K2 clutch, so on had 1,3,5, and 7 gears.

Had the Mechatronic Unit replaced, but then had a gear grinding noise when I got the car back. I had to fight them to replace the Gearbox.

They eventually replaced the gearbox. however when they did they forgot to bolt it to the cradle, so I had a gearbox that kept bouncing around when I drove on uneven roads.

Had everything sorted since then, and its going strong. I'm preparing now to do APR pulley and software.

Hope you come right man

Well...bad news and good news. The bad news is that they think my mechatronics failed but the good news is that they don't have to replace the entire transmission.

Hopefully this fixes the problem but if it doesn't I'm going to insist on getting them to replace the gearbox.

They didn't care one bit about the exhaust, but they kept asking me if the engine was tuned because the clutches were running very hot. They said that the engine was making more power than it should be, causing extra load on the DSG. I don't have a tune and told them that they should be able to tell if I did. They then asked how I would know that, and I mentioned the TD1 detection when they scan. They said they scanned the car but still believed I had a tune as the engine was making much more power than it should. I told them to scan it all day long, they won't find anything because there's nothing to find.

Within a couple hours they called back and said they believed me. That was the end of that discussion. Very odd. So either I have a factory freak for an engine or they were just bluffing to try and get me to bite. Either way, I don't have a tune so I'm not too concerned.


More proof that this TD1 thing is just fear-mongering. Glad to hear your dealer is treating you well. Perhaps you should post which dealer it is -- they deserve to get more business.

Update2: The gearbox malfunction error did pop back up again yesterday (3 times); not only did this error pop up but also got a parking brake error as well. Got to a red light and put it into park, turned the engine off and then went to turn it back on but it wouldn't start - couldn't read that I had the shifter in P or N. Tried this several times and finally got it to start. Took it into the dealership today, so we will see what happens and whether any TD1 flags keeps them from fixing it under warranty. It clearly seems to be some electronic/sensor error with the gear selector lever...

Update from the dealer: The sensor gearbox malfunction error I am getting is from a sensor within the transmission itself. The service advisor stated that the sensor was not "servicable", I guess meaning there is no replacement part or they can't fix it. They would have to replace the entire transmission and the bad news is that beause my car is tuned (aka TD1d now) it cannot be replaced under warranty.

Good news is that the transmission is working fine it's just this sensor error that may come on sporadically. They said it occured twice yesterday in the shop but never came on today. I guess my option at this point is to just drive the car since it's causing no mechanical problem at this point. I'm certainly not paying $13k to replace the transmission unless more problems start to occur as a result. Either that or trade it for something else...

Well I don't think that they can claim that your tune is causing this issue. I'm having the exact same issue and I'm stock (as are several other people with this issue). I think if you brought it up with AoA you could get a better resolution.

Well, just heard from my service advisor. The mechatronics unit was ordered on Tuesday, being coded today and should probably be ready for install on Monday. Would be great if they were able to diagnose and fix the problem in only a week (especially since they had to do a lot of testing and order the part). I'll let you guys know once it's in if it fixes my problem.

Unfortunately, yes they can claim that the tune is causing the issue. It may not be right, but it gets them out of paying for the claim.

wow i guess not just fear-mongering anymore.


i'm getting the "gearbox malfunction you can continue driving" message pretty consistently now. I got it once about 2 months ago, and recently i got it 4 times on an hour long trip and once every other day. Going to take the car in for service, if they give me this B.S. 13k bill then i'm going to just trade the car in.

burrito, in this case it is very much a possibility that the excess power has stressed the S tronic past its design limits. We don't know.

My comment about fearmongering was that a person would go in for a burnt-out tail lamp and a dealer would say "oh we're not fixing that, you have TD1."

no im pretty sure everyone's fear was about transmission, diff, and engine problems... why would anyone go to the dealer for a tail-light?

Burrito, any update on the cause of your malfunction issue or did you take it in? Mine ultimately did what yours is doing. Started coming on almost everyday. I've since traded my car as I don't have the time to deal with it and also didnt want to incur the financial risk. I guess the term "pay to play" has a lot more meaning to it when you potentially could have to pay to replace the transmission yourself.

08-27-2012, 07:17 PM
Any updates?
Has anyone encountred new issues or reoccuring issues with S tronic as described in this posting?

My S tronic still jerks into first gear when coming to a stop and/or when taking off from a stop, it jerks into first gear.
I drove a new Boxter S and a new 991 Carrera S and that was the smoothes transmission's I've ever driven during the Porsche Road show event in Alameda. PDK is beautiful thing, too bad Audi can't learn to tune S Tronic from their big brother...

Thanks

I had this problem and my mechatronics were replaced about 2 weeks ago. I've put on 500+ miles and the problem has not come back. Seems to drive smoother and less jerky at slow speed too.

Well, after shutting off the car and letting it sit, the CEL cleared and just left me with a TPMS light. I checked the codes to confirm what the MFD told me and have posted them below. I checked the tire pressure to be sure (it was normal on all 4 tires) and reset the TPMS.

IMO yes. The only real advantage DSG gives you is if you get tired of hitting the clutch and are in traffic often. I went DSG so the wife could drive it as well. Manuals are of course significantly more fun too. Oh well.

In an effort to convince my wife we should get a manual we found a place that would rent us one and I taught her in that. Unfortunately she still hated it. =/ Still though, it's an option I'd look into if I were you! That or find a friend with a truck. Those tend to be easier to learn on too. =)

That's exactly what happened to my car, at first it seemed to cure the issue and then it slowly got worse. I sent letter to Audi, we shall see what happens next, that's all I can say at this moment.

Good to hear.

Part of that is also because it has fresh fluids and because the clutches are not worn.

My previuos S-tronic tranny never felt like this, it was rough, jerky and brute from day one. The mechatronics was replaced at 6K and fluid, it was ok for about 3K and then it got worse. Sometimes the clutch would slip off line and when cruising at light loads (20mph) and under full throttle it was causing my car to bounce off rev limiter with no gear in sight.

I'm just stoked, I'll drive it for a while and update the forum to see if it changes.

Thanks for the support.

I took out a TT RS yesterday and looked at a RS5 that was in the showroom. I was offered $34,000 for my S4 which has the intermittent gearbox malfunction. I think it's time for me to trade in this car. Has anyone had their tranny repaired or replaced after flashing their car back to stock?

update got $36K for my 2010 with 85,000 km and about $3000 in vandalism damage which needed repair. Took a cash out from the insurer for the $3K therefore in the end I got $39K for the trade and only paid tax on the difference of the new car.

Just got this message on my 2013. Joy. Going out to vagcom it and see what's up. Fortunately it happened a block from home.


Seeing a 2013 with this problem made my heart sink - as I have one on order with the flappy paddle transmission. I was so hoping while reading this thread that it was on earlier models, like the water pump issue.

Oy.

I like manual transmissions, and my wife can drive one, but I ordered the DSG for improved performance and easier use. I hope I am not regretting that decision a few months from now.

As an aside.

The M-DCT in my first (2009) M3 also failed, initially "remedied" with software updates and after the third failure in under six months, BMWUSA and I had the lemon talk. At 23 days out of service, they overnighted a transmission from Germany to replace the one in the car. I wish to also say my dealer (Thompson BMW in Doylestown) was excellent in the process. After getting a new transmission, it was fine for the next 40K miles until I traded it. The replacement transmission was better than the original ever was. The original was jerky and really dumb in auto mode. Nearly undriveable.

My current (2011) M3 has an M-DCT and it has been fine with 22k miles. I attributed much of this problem to new mechanical components and the sometimes reduced reliability in the 2009 M3 which was one of the first with the M-DCT.

My only suggestion, and this will be my approach should, God forbid, my new S4 be problematic, is to be aggressive early with Audi of America. Had I been more aggressive earlier on in the process with my RS4, it is likely they would have brought in someone who could durably repair the primary issue (DRC) and I would not have ended up lemoning that car out. By the time I got AoA involved, the car has been out of service for two of first five months, jerked around by the dealer (now out of business) and I was just fed up. Audi had a traveling service agent (from what I was told) at the time who was going to dealers with specific equipment and skills and was effecting durable repairs on the DRC. I miss that car, still. When it ran, it was awesome.

AoA is still in the contact list on my phone.

Also, a question as I don't have my S4 yet. Does the car have a "walking" mode, like my M3 with the M-DCT? That is, in bumper to bumper traffic rather than feathering the gas and crawling along, which rides the clutch non stop and in the owner's manual said may result in overheat, it has a mode where a quick tap of the gas pedal keeps the car at just over idle, engages the clutch fully and walks along at about 2mph. It requires a bit of thought in traffic, but is doable, and after 70k miles is second nature to me now. Even in bumper to bumper traffic, after leaving the highway where i was driving in a spirited fashion, at `100 degrees outside with the AC on, I never got a message of transmission overheat but I always use the 'walking' mode.

Did the issues described above occur in heavy traffic? Not blaming the driver for the failure, of course, just thinking out loud

Just got this message yesterday while at a stop light "transmission malfunction: limited driving functionality" & TPMS malfunction at the same time. I pulled over to a gas station, turned off the car, waited a few minutes. Turned the car back on. Transmission malfunction message gone but TPMS stayed. I just resetted the tire pressure in the car menu and it also was gone. Drove the car to the dealer but because the message was gone and it was late I decided to drive it home. My 5k is coming up. Hope this isn't a mechatronics issue.

Had this happen to me at 3k miles on my 8.5. Happened only once and 5k later everything is still fine. Only difference was that I also checked my tire pressure and reset TPMS again. Didn't clear the errors with vagcom and at the 5k service I asked the dealer and they said it had cleared itself and not to worry about it - but they did document it.

Literally the exact same issue though, same lights, same behavior, etc though.

Hey Fellas,

My car has 19K now and the new tranny was installed at 13K. The car still runs smooth, no jerky shifts up or down, very smooth BUT...
My car has been back to the dealer four times now with oil leaks, dealer found pan bolts loose the first time.
Secon time they replaced the gasket.
Thrid time, the gasket and pan were replaced.
I just dropped it off again for oil leaks, dealer thinks the new tranny may have a crack, wtf!!!

I'm so over S cronic and I can't wait for my new B8.5 to arrive and its a manual [up]

I now have 27,000 miles on my 2011 DSG with no warning lights to date.....fingers crossed. The transmission has always felt jerky from day one. There are times where it will slam into gear or other hard shifts but no warning lights. I took it to my dealer early on and they said all software was up to date and didn't think it was a problem because jerkyness is inherent of the DSG transmission. ??? All these posts scare the shit outta me thinking I would need to pony up $12K out of my 50K warranty! I think these best way is to trade it in on a new one before the 50K warranty is up. It would also be nice to know what is the percentage or number of units failing and in need of replacement? Not everybody that owns an S4 is on this Forum.

Sadly, I think it's just a matter of time. Hopefully, MT available for one more generation or I may be driving my B8 for a loooooong time.

I would think that Audi should be happy every time someone picks an MT as they are certainly not costing Audi as much in warranty claims.

However, it seems that the more you spend on a car the more time it spends on a tow truck.

1. Water pump failed after only 12 months fixed under warranty.
2. Thermostat failed exactly 12 months to the day after the water pump failure
3. DSG Gearbox Malfunction requiring the mechatronics to be replaced only 3 months out of warranty and 70000 klms. $8000 repair bill with no sympathy from Audi.

This is really getting me worried now. Will Audi ever do anything about your mechatronics if there are no alerts on the dash? I only have about 10k miles left on my warranty. Although i haven't gotten any alerts yet, i feel like i have experienced some symptoms that others are saying.

The symptoms are:
-Hard, jerky shifts when manually shifting 1 -->2 under 3k rpm
-Occasional laggy 1-->2 shifts in S mode when flooring it.
-Occasional revving (as if i'm in neutral) in manual mode when slowing down abruptly in 4th gear and then getting back on the accelerator again

Hmm...Similar worries here, different symptoms... . 2010 with 30K miles, CPO thankfully.
Mine did the laggy jerky shifts in S mode that you describe, and seemed to "jump" and make a "clonk" noise when shifting from Park to Drive (and back to Park and S, to verify what the hell happened, yup still clonking). It did this when parked at my kid's school, then shifted harder than usual on my way home. I attributed it to me not being used to sports mode, but nope. Once home it clonked some more moving back to park. I almost booked a service appointment on the spot, but no warning lights, so..... Odd.. Restarting it 20m later, all was well, and has been ever since... ?!?!? That was a hot day and I had been playing with the paddles a little bit, but nothing crazy. Now I'm waiting for it to happen again or for the dash to light up so I can exercise that CPO warranty on -presumably- the mechatronics, but so far nothing...

I'm almost disappointed I didn't get a code, ironically, I don't like occasional malfunctions - with my luck it'll finally die when the CPO expires...
Kinda annoyed I could not find a local 6MT, but I hear those shift funny too (like a CDV issue). We shall see...

I have had my mechatronics unit replaced already I still get that revv'ing as if the car is in Neutral. I dont know what it is but I have had the Mechatronics unit replaced, the rear drive shafts replaced, I will see what happens. I have had the DSG re flashed a bunch of times to re learn what is going on. Nothing. Hoping a DSG tune can fix it slightly.

Probably wayyy to early to ask this, but anyone with a 2013 having DSG issues? I do know that they changed some parameters on the shifting logic in the b8.5, and many users reported smoother shifting. But reading all this really makes me wish I went 6MT, guess I'll have to pony up for the extended warranty...not sure how this affects going with a Stasis stg 1 tune.

I have had Similar issues in my 2010 S4. No warning lights. Hard thunk when slowing into first gear and hard clonk when shifting to park. It usually happened when stuck in stop and go traffic. Sounds like transmission overheating. Audi service yielded a reflash. It worked great until just recently when the problem reared its ugly head again although it was minor this time. I dont like this. I would rather have a hard failure and get it fixed. no CPO however my car history had the pump and thermostat recall so I should be covered under the extended 6 year 100k mile warranty.



Probably wayyy to early to ask this, but anyone with a 2013 having DSG issues? I do know that they changed some parameters on the shifting logic in the b8.5, and many users reported smoother shifting. But reading all this really makes me wish I went 6MT, guess I'll have to pony up for the extended warranty...not sure how this affects going with a Stasis stg 1 tune.

If you jump back a page or 2, yes there have been a couple of 2013s that have had this issue.

after doing some research and thinking back on my own experiences, I believe that the OEM DSG cooling unit is the issue. The reflash is just a band-aid. Replacing the mechatronics unit is what results after multiple over heating sessions.

It goes like this - Transmission overheats, Transmission computer starts messing up the shift algorithms. Eventually Transmission mis-shifts begin to damage mechatronics unit. It is a sound theory anyway.

Does the TSB reflash help with the 1-2 shift issue where it holds the shift way too long and cuts power? If it doesn't fix that then it's not worth it for me to get my GIAC tune removed, go to the dealer for the TSB then have the tune flashed back in.

What do you consider hot? Operating temperature or flogging the car repeatedly? I never redline the car until it's reached 200F+ any how.

Operating temperature. During stop and go running around the neighborhood on a hot day (never going more than 30mph) was when the problem first appeared for me.

Speaking (Writing) off the cuff, and not trying to blame the owners for the issue, stop and go traffic is very hard on a dual clutch transmission. Essentially, it is slipping the clutch near continuously to crawl along. Add 90 degree ambient temperature, hot exhaust from the car in front of you and the AC nice and cool and there is a lot of heat around the drivetrain.

My prior M-DCT M3s had a "walking" option where a quick tap of the gas pedal would engage the clutch fully and walk the car at about 2.5 mph. Thereby not riding the clutch. It was a feature designed specifically to avoid this issue. I think this is further complicated in the Audi with the S-tronic as this transmission is calibrated to feel more like a conventional torque convertor auto. In most situations, one would be hard pressed to distinguish the S-tronic from Tiptronic driving around town. Okay, maybe on hills where it engages from a stop somewhat abruptly. The M-DCT made no attempt to be smooth like a conventional auto. There was no doubt in most any situations that this was a different kind of transmission.

that said, Audi should have designed the transmission to tolerate normal driving conditions in the real world. Or added a "walking" mode, like BMW, to address just this issue.

Whether or not it will make any difference in the long run, I think about the S-tronic when in traffic. If at a light, I will pop it in neutral to take the load off the throw-out bearing. I don't creep along in bumper to bumper. I move in increments - much as I would in a traditional manual. Maybe pissing off those around me as I am not continuously up the ass of the guy in front of me, but less pissed off than they would be if my car shit the bed right there in front of them in traffic and blocked a travel lane.

Only at 7500 miles on my 2013 S4, living in metro PGH, occasionally commuting downtown, and so far no issues.

Interesting theories, I have also been surprised how well the s-tronic feels while creeping. Do you think this causes additional wear on the clutch packs or stress on the mechatronic unit? I would imagine impulsive forces during hard driving would be worse for wear and tear but that's a total guess. My understanding is the Getrag M-DCT is dry vs the wet DCT's of the VW AG family (PDK, Stronic, golf DCT), so maybe that changes how clutch play works at low speed? I know Ford has had a lot of problems with their powershift Getrag 6-DCT with dry clutch's, which presumably uses lesser quality light weight components.

that again doesn't make sense. If you were to get a bench flash TCU upgrade you physically take out the mechatronics and send it to whoever is flashing the software because those actuators are together with the circuit board etc. The Mechatronics is the brain of the transmission.

Love the finish, handling and looks of my 2010 Audi B8 S4.

However, it seems that the more you spend on a car the more time it spends on a tow truck.

1. Water pump failed after only 12 months fixed under warranty.
2. Thermostat failed exactly 12 months to the day after the water pump failure
3. DSG Gearbox Malfunction requiring the mechatronics to be replaced only 3 months out of warranty and 70000 klms. $8000 repair bill with no sympathy from Audi.

This will be the last Audi we ever buy. Can not recommend Audi for reliability. [mad]

While the first two was obviously due to some production problems the last one being DSG really is unacceptable. The DSG transmission being a major component should not fail so early in a cars life especially at that cost. I definitely won't be going with any cars with DSG on my next purchase as it looks like Audi can't make it reliable in the long term and are not backing the product. I know when BMW had the HPFP problems they gave the owners a 10year warranty. This is what Audi should do with the DSG with all the failures. This is definitely one area where Audi needs to step up to the plate and back the cars since obviously some of the parts are not well designed.

When I think of the word "mechatronics" I think of robotic's inspired composition of electronic control units with actuators of whatever sort. I presume the actuators in the DCT would be big and buried within the transmission housing. If you are going to bench flash the TCU, I don't understand why you would take out hydraulic actuators. Check out details of the M-DCT by Getrag here (http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CDAQFjAA&url=http%3A%2F%2Fwww.m3post.com%2Fforums%2Fattachm ent.php%3Fattachmentid%3D587904%26d%3D1317583307&ei=krmoUeY9qeTKAb2GgIAM&usg=AFQjCNGU6ICQDs3kIOin2erL1uMNwn4Y7w&sig2=CvS2Z20e2Pkh5AX4NQnbLg&bvm=bv.47244034,d.aWc) (page 30).

I think the DSG controller is near the sensors & actuators. http://www.audizine.com/forum/showthread.php/356141-Details-about-the-Seven-speed-dual-clutch-gearbox-0B5-S-tronic-%28DL501%29

"The mechatronic system acts as the central gearbox control unit. It combines the electro-hydraulic control unit (actuators), the electronic control unit and some of the sensors into a single unit. On account of the longitudinal configuration, the rpm sensors of both gearbox input shafts and the gear sensor are located on a separate mounting bracket.


The mechatronic system controls, regulates and performs the following functions:

– Adaptation of oil pressure in the hydraulic system to requirements
– Dual clutch regulation
– Clutch cooling regulation
– Shift point selection
– Gearbox control and regulation
– Communication with other control units
– Limp-home programs
– Self-diagnostics"

Isn't that lovely that your transmission bites the dust 2k miles out of warranty and again hiding behind the tune is simply insane but that's Audi. I am not so sure about it needing a full transmission replacement, and may just be a mechatronics but geez, I would have a hard time stomaching 11 grand because of poor design on audi's/VAG/zF's behalf.

I personally have never had any symptoms before a warning on the dashboard (gearbox malfunction limited functionality) then it goes into i'm going to murder you mode and slips the clutch/neutral at anything over 2k rpm where it takes ten years to go into the next year.

So would they have covered this even though you were out of warranty if you did not have a tune? If so, that is complete BS that they would deny this based on a tune given the fact that this is a documented, known issue with the DSG transmission. There is even a TSB that all dealers have for this issue due the number of occurrences.

This was the exact circumstances that I experienced today. We are having unusually warm weather here the past 2 weeks (for us in the UK) 32C/90F. I was stuck for 1.5 hours in stop start traffic jam.

I’ve never experienced both conditions, occurring simultaneously, until now since I’ve owned this car

I kept putting her into ‘N’ when stopped because I worry about them pesky clutches and put the e-brake on. Traffic starts to move a little so put her into drive and even with (obviously) my foot on the brake big clunk, felt as if the car had been slightly rear ended. Go to pull off, thereby releasing the e-brake, big clunk forward as I touched the throttle (again as if the car had been slightly rear ended).

Didn’t happen all the time just intermittently, so I started to experiment a little and it occurred in all modes both in ‘M’ or ‘D’. One of my mates was travelling with me and he commented on the jerky nature once or twice. Quite embarrassing really.

So I wonder is this actually quite normal for the DSG at elevated temperatures in prolonged stop start traffic jams after all other cars I’ve owned both manual and auto have done funny things, transmission wise, under similar conditions?

I've just noticed this thread. My 2011 stock S4's DSG transmission was replaced about 6 months ago, at about 22k miles. I got the dash indication something like "transmission fault, OK to drive" while tracking one day. VAGCOM showed a fault indicating a sensor for the gear shift lever. Other than the indicator, it was working OK and I finished the track day. For the next few weeks on street, the same dash warning would occasionally come up. I did not have time to take it into the dealer and had another track day. During one of the sessions it simply went dead, no power, no throttle response, no response to shift lever. I drove off course, stopped, could not get started again, waited for a tow. When the tow truck came I found it would start and drive OK. Drove it straight to a dealer who confirmed gear lever sensor needed, but of course they could not fix right then. Drove 100 miles home and took it to my local dealer. They called a few days later saying it needed a transmission replacement and it would come from Germany. Then they found on in Canada and it was fixed a few days later. So far no more major problems. A minor problem is that in slow traffic, when slowed to 10-15 MPH and in 3rd gear, and traffic speed picks up again, applying throttle causes a rough shift into 2nd; almost like it does not release the clutch soon enough and the RPM has gone too high for a smooth shift. Car now has about 30k miles.

Also, they had to ship a whole new tranny from Germany, so that took some time.
They acted like they hadn't seen any issues with the DSG box (and I couldn't cite the numbers off the top of my head).
It is important to note that I hadn't seen any issues- except for the slow to bump issue I asked about earlier.


On the positive, they did the 60k for free and I got a loaner Q5 for 8 days.

Similar action should be taken for DSG users in the B8 S4 community. (Tuned and Non Tuned Versions alike) We are seeing many clean cars with no modifications see this problem once, twice over. We here in Norway are also seeing a large number of these cars. A lot of you are posting out of North America are having a really hard time getting the dealers to own up to the known concern.

At the 55k service had to replace 2 cracked engine mounts and wonder if around the same time if that's what started the problems w/the DSG trans.

Dont blame you for getting out of it. Its was odd - I would go a week or month w/no gear box warning - then have 6 or 8 warnings in a day then nothing after a short stop and resumed my commute. So I also wonder if it may be electrical - short - weather induced (my car is always garaged).

I loved the tune - and will do it again once my lease is up. And yes, I feel for the next owner - I took care of all the other things / replaced engine mounts / 55k service / new tires....but got it all back in equity for my lease.

But again - the APR tune I will do again - just not sure if I want to install the pulley 'again' on my own...its a PITA. I may take the plunge to get my own VAGCOM and start my mods there - 2nd purchase will be a new grill.

The other day when pulling out in traffic I floored car to make it and it did not shift out of first. Car was in drive, pulled over to check everything. No warnings/errors, pulled back out and started to shift normally.
I just bought this car two weeks ago, 2011 S4, and during the PPI they noticed that transmission gasket was leaking. I had the previous owner take it to the dealer to replace the gasket under warranty and noticed a bolt was backed out of the Mechatronic unit. Since there was no torque specs on the bolt audi replaced the entire Mechatronic unit with a new one. Hasn't happened since.

New to the forum, so saying hello as well.

Welcome to the forum!

I think that has happened to me three times out of the 15k on my car. Never consecutive. Always when I'm trying to floor it. It feels like the car doesn't shift in time or something. Idk how to explain it but how u described it seems about right. Did it happen to u consecutively or just once?

Just once, and it didn't shift at all. It was stuck in first and I believe it was bouncing off the rev limiter

Hmm, I stopped at a gas station after driving home from work yesterday and accelerated pretty hard out of the parking lot on my way out, sliding the back tires for a mini-drift. I was in manual mode pulling 2nd and 3rd to pretty much 5k and once in 4th found myself stuck. Couldn't switch out of 4. Switched back into D mode and it proceeded to function as normal. Could be that I was attempting to downshift and the computer was rejecting that input, but I'm pretty sure I tried to go into 5th.

In any case, I'll do a quick scan and keep a close eye. I DD the car and don't push it hard too often, maybe rev it out to 5k once every other day or so.

more and more and more creeping up.

A stickied survey of some sort would be handy to see where the failures lay. Tuned or not and by what tuner as well as model year.

I am honestly very apprehensive to reflash the car with the APR software after I fought with audi for two months and if it were to fail since it has been in stock/oem calibration the entire time since the replacement, will I have to fight again or will they admit it is a faulty part?

Stock and tuned cars getting sacked with 6-14000 dollar repairs on a brand new car is just wrong and the more this is creeping up, the more it shows that there is a problem with the design/manufacturing or whatever with these transmissions/mechatronics units.

And the other question is at what point is audi going to admit something since i'm sure they don't want the bad press that the FWD dsg earned (as alarmist as it was).

Possibly, yes. The DSG seems to have more guardrails on it than some other transmissions. Our cars will automatically shift at the redline, even in Manual mode. That's not the case with, say, the C63, whose automatic will let you go straight past and roast the engine in manual.

Based on the design changes Audi made to the new mech units, it's believed that high temps causing circuit board issues were the cause of the failures. The fluid temps would get so high that the conductive material that the TCU was housed in would get so hot that the brains inside would be outside its operating range. When that happens, the signals sent to the mech unit would be all wacked out and you'd get missed shifts, hard shifts, whatever. The new mech units seem to be plastic housed units with additional shielding to help prevent this problem. Along with that, it is believed that Audi changed some of the coding in the calibration to help lower temps further by controlling the clutch packs and torque transfer better. Of course, it is still too early to tell if the new design changes will help. The one thing that gets me is... you'd of thought Audi would have learned it's lesson with putting the TCU brains inside the tranny and basting it in the fluid used to lubricate the gears... i.e. the CVT issues they had in the past. When will these people learn? Put that damn TCU on the outside of the unit and heatsink it like a mofo. Not to mention an external location design like this would make for a quicker and cheaper change should it fail. But nooooo, they had to integrate it into the mech unit and throw it into the hot soup inside. :rolleyes:

Just got a resolution to my DSG, for now. My dealer reflashed my transmission with the "latest software" and it does seem to shift smoother and the "falling out of gear" has not recurred yet. They have reflashed my transmission before, but they went off of the TSB which according to them loaded software version 8. This time, they loaded the newest software, which is version 12. I'm pretty happy for now and I guess I'll hold off on trading in my car for a 6MT... for now at least [:D] Let's see if the problem comes back

BTW, I have to thank them for giving me an base A4 while my car was in the shop... I appreciate my car sooo much more now!

Not so sure, the transverse DSG recall was massive and they extended the warranty to ten years after there was an NHTSA investigation and they fixed units largely tuned or not. The new TD1 crap Audi is starting to push away people and blaming "the tuners" even though arguably these failures are happening on tuned and stock cars as they seem to be releasing TSB's regularly for these transmissions.

Wouldn't hurt for american's (we don't have this sort of thing in Canada) that have had the issue to file a complaint with the NHTSA if you have had DSG issues. This will at least force an investigation into this and potentially get the warranty extended.

+1 The problem with Audi or VAG in general is they don't back up the product. If they said we understand that there is a problem with the DSG and offered us 10year warranty for the DSG than I wouldn't hesitate to trade in for another one but Audi is basically saying screw off after they sell it to you.

Almost 19k on the dial and the transmission decides to die on me.
Temps hit almost 90 this afternoon, so it may be related to overheating.

I immediately got the Transmission Gear Icon and You can keep driving. The car was real jerky shifting.
I then park it in the street and charge up my laptop to do a scan.

I figure ok, let me get it to the dealership before they close at 6pm so they can check it out.
I make a turn out from my street and bam, the transmission goes haywire. Jerking like crazy.
This time TPMS and Gear Icon show up, but it says put the car in Park and turn off immediately.

I try to restart a couple of times and no dice. Call Audi roadside and they can't get me to the dealership before close.
So I decide to try and put in neutral and get some help to push it back into driveway. No Dice.

Call a tow truck, waiting 2 hrs to bring me half a block home....
I give it another restart after letting the car cool for 15 mins and the thing is able to move now.

$hit don't make sense and I'm going to have it towed to dealer first thing in the AM.

Anyone know how to read the vagscan? Is it just a sensor or does the whole tranny need to be replaced?
TPMS alert is still there, but transmission error is now gone..... WTF...

Leave it alone, don't erase the codes. They'll be stored. Those should be the codes for the drive range sensor failure which has a TSB for it failing and what they'll need to do to change it out. There's a post on here with the specific which states even what codes to look for before the TSB even applies. If it does, expect at least a week's downtime. They have to tear it completely apart... The DSG that is, to get to the part they need to swap.

Just looked it up P179E is definitely the primary code needed for the TSB, however, the other doesn't match up. More than likely, they'll call Audi TAC and they'll tell them it's probably the same failure for the TSB to apply, but also check other issues too. TSB is 2032211.

(405 x 9,000) / 5,252 = 700 hp????

Although it doesn't necessarily scale down precisely, is there anyone even running anything close at this point?
I think it would be more interesting to find out if there are any clutch packs we can upgrade to. TCU upgrades are no question at this point.

Damn, this is a huge fear with this car, was hoping they had sorted the B8.5 DSG out....let us know how it goes please!

I don't think torque/HP handling is the problem, biggest failure mode seems to be heat generation during low speed creep in humid conditions, and other situations where the clutch slips.

Here's a thought, and might be a dumb one: would it make sense to change the DSG fluid more frequently? Any reason to believe fresh fluid would help the system improve the heat dissipation etc?

It was definitely hotter than usual yesterday and the car had been sitting in the sun in my driveway.
I'm at the dealership now and they were not at all surprised when I mentioned what happened...
Must be a batch of bad circuit boards/sensors... or maybe the fluid needs to be changed.

Hopefully I can get this resolved asap as I'm planning road trips soon...

Here's the thing I don't get: I understand it was hotter than usual, however, you said this happened when you *first* pulled out of your driveway. So in that sense, it's not like the trans had heated up like it might during some serious bumper to bumper traffic in hot humid conditions.

Can you say with certainty this is the first time you've experienced abnormal behavior in your trans?
What are most of your drives like? Commuting a lot, low speed traffic etc?
Do you shift yourself often or let it shift in 'D' mode? Reason I ask is because the auto program in 'D' mode really likes to short shift and hunt for the higher gears, which in my mind must involve more clutch slip, and consequently, more heat. Especially while creeping in traffic.

Sorry to hear of your troubles and hopefully gets sorted out soon.

I drive thru some of the worst roads in NYC and do about 1k miles a month.
Short trips in stop and go traffic daily and a 4-5 long road trips of 600-700 miles since ownership.

As far as weird transmission behavior, I do get some weird transmission lurch here and there in stop and go traffic.
Basically when slowing down at low speeds the car feels like it lurches 6 inches more than expected.
I've gotten used to it.

My Mech unit has been bumping and exhibiting the dreaded 2-1 bump shift that causes the car to lurch forward 1' when coming to a stop. Recently as the temperature increased this condition seemed to be getting worse, add to that I began getting the gear symbol and reduced RPM's due to high Mech clutch temp. This issue manifests itself after stop and go traffic in moderate to warm days (10C-15C) then park the car for a short period of time (30min) then the first 1/3 pedal acceleration the code pops up.

I have the car at the dealer for service, I have an aftermarket warranty that is covering the repair, but the warranty company is sending an adjuster before any work begins, glad my car is not TD1 and has no appearance mods at this time. The dealer will be updating all software and replacing the temp sensor this go round, I have a feeling I may be back in the future for a new Mech unit. My SA was nice enough to get me into a 14 A6 TDI Teknik while I am waiting for the return of my S4. I don't mind the size, in fact it makes me regret not saving up for a couple more months and buying the S6 instead

That's probably not going to help Mantis. It's a physical failure of the part, not software that causes this issue. They'll have to break down and replace the entire unit with the new revision to fix it. Shame really because in their wisdom or lack thereof to save money, they'll actually pay more in labor to go in there twice and not to mention ~$300 just for fluid alone. [facepalm] That SA/Tech is either wanting to milk the warranty company or they just don't know the appropriate fix for this because its their first one... hard to believe that with almost all 2010 DSGs having done this... at least a good % of them. Sooner or later they all bite it.

(405 x 9,000) / 5,252 = 700 hp????

Although it doesn't necessarily scale down precisely, is there anyone even running anything close at this point?
I think it would be more interesting to find out if there are any clutch packs we can upgrade to. TCU upgrades are no question at this point.

There are upgradable clutch packs, they are about $2k, and ironically support 700hp, though in reality, it's direct TQ that matters, not HP so much.

I am fully aware of the proper repair, I have suggested that the Mech unit requires replacement, but the Audi Master Tech disagrees. I am not sure if they are trying to soak the warranty company or not, and frankly it doesn't concern me, as long as I am not out of pocket and have a suitable replacement driver.

Now we just wait and see, I have a feeling the warranty company is a little pissed, I have never had them insist on sending out a warranty claim adjuster in a situation like this

I guess I'll update in this thread.
Car is still in the shop now for the 2nd DSG failure in a week.
So far it's a bad solenoid in the transmission.

Might be getting a whole new DSG now.

Confirmed new tranny on order.
I'm worried to take this car on a road trip now.
I've been driving over 20 years and never had a car die like this.

Does Audi Roadside cover highway towing?

This is just so "fuct" and terrible timing since I'm moving soon.

They are replacing the entire trans, so I kind of doubt the issue will linger. Now whether or not it will resurface in another 20k miles with the same driving habits is a completely different story....

Pretty sure Audi roadside will cover towing to the nearest Audi dealership (where they'd give you a loaner or make you get a rental), but I doubt it covers towing the car 500 miles to your new home. They would then fix it where ever it was towed to, and make arrangements for you to get the car back. Assume they would go out of their way to make you happy in the end. Source: read about the same thing happening to some guy on the F30 board (BMW seems to have worse customer service than Audi from what I read there).

New trans is a god save. Go with it. I don't know why you're worried about that and weren't worried about them just changing a part in it. A new box is way better. Those with B8's and new trans replacements have been pretty quiet.

Parts are on order for my dsg, the master tech agrees that this is most likely not the fix all for it. Seems like the warranty company is willing to take a chance on it, most likely they will have it back within a week or two for the correct action

Was hoping they'd assist with a trade for a new vehicle.
I guess having the car flat bedded twice in a week and almost getting into an accident has got me miffed...

I'm just going to pickup a new Forester for the long road trips. Keep the S for my daily commute.

My mechatronic unit was just replaced yesterday and I must admit it's night and day. I too was hit by multiple error codes and limp mode. I believe the software was also updated to the latest version as per recommended by @SwanPeRFection in another thread. Downshifts are much smoother in dynamic mode but ine downside is that the typical burp when shifting in dynamic mode is now more tame. An exhaust will solve that in the future.

Service was great from the dealership, a fresh breeze coming from Subaru. I feel like I have a brand new car and I'm ready to go stage 2 now that this is cleared :)

Call them up before you go to get it and make sure they applied the 24AS campaign to it. It's an ECU update for drivability... I think you may like it. Very smooth for now, in my experience.

Yes, it has been applied and the dsg filter you spoke of at no extra charge. Good service here in Canada.

I picked my car up yesterday, I have been beating on it and trying to have it throw the codes again but it seems to be a complete different car to drive. No more thump for 2-1 shifts, no more lazy delayed 1-2 and 2-3 shifts. My fuel mileage has more than doubled and I am pushing it.

Seems like the repair was at least a step in the right direction.

Also had the 24as campaign applied as well as updated TCU programming

I have an RS5, 34k miles.
Today, I switched it off after a 20 minutes spirited drive, no error, all fine. After half an hour, I went driving it again , started the engine and gearbox malfunction, I couldn't move the car as it didn't select any gear, stayed in neutral. I tried switching it on and off, hoping the error will clean, but with no success. So I left it parked for the next two hours and when I tried again all was fine, I was able to drive it, no longer the error.

However, I went for another 10 minutes spirited drive, everything is fine, gear shifting is nice. After I turned off the engine, at the next immediat attempt to drive it, again gearbox malfunction and cannot select any gear, stays in neutral. After I let it for two hours, again car runs fine.

Looks like gearbox overheats and go limp mode. Tomorrow will send it to the dealer to read the error codes.

I hope it's nothing expensive, as the car is outside warranty.

Well,

After the mechatronic unit was replaced roughly three weeks ago, I've been experiencing some issues ever since. First, I had a max 4000 rpm notice in the dash with the EPC light on, which disappeared after restarting the car. I thought this was just tome random code.

Shortly after, the car came to a complete stop right in the middle of the highway... during rush hour. I was able to turn off the car and start it back right after. You'll understand I was very lucky not to get rear-ended at over 50 MPH and that I was alone in the car, as I have a one-year old daughter and my wife's pregnant. Freaky, you'll agree.

This morning, the car would simply not start at all. Started was doing its job, battery is just fine but the engine wouldn't fire. As I was waiting for roadside assist, the car finally started so I drove to the dealership.

Bottom line is the car is currently being inspected as the issue seems to be related to the mechatronic unit that was just replaced. My SA is telling me they're looking into it to determine if the problem is related to some technician's bad job or a faulty unit.

Things are adding up and I'm getting very, very frustrated.

Stick with it, I just had my Mech unit replaced, and for the first time since i bought the car, I am really enjoying it.
Once they get it together, You will be happy and its worth the wait and frustration.
