Haldex failure thread

[yeedub]

When I had this issue, the AWD fault code would be logged after every burn out from launch control

[Makersmark]

Discovered Haldex issues from burnout on launch control and wheel spin under heavy acceleration in first. 2015 with 39k. I purchased CPO a little under two months ago. I took it to two different Audi dealerships, both of them saying nothing was wrong. Both techs talked about how experienced they were driving 600 hp racecars so they know what they're talking about, and that there's no way to avoid wheelspin. I sat with one of them during the diag test drive and watched the TC light up while accelerating in 2nd, still normal according to them. Luckily all mine took was a OBD11 fix. [22] AWD ->Basic Settings -> Pump Motor. I haven't had a chance to try launch control again but the spin under heavy acceleration is gone.

I have a 2015 A3 with haldex, there isn't enough power for an AWD burnout.

My launches only had excessive wheelspin when my haldex unit was broken.

My dealer covered it under warranty. If I were you, I'd just attempt to return it and look up lemon laws in your area.

Mine is s3. And if it was an awd burnout wouldn't that imply that the rear wheels are engaging? Mine was just spinning front but it's fixed now.

[DeadxDawn]

Well, I've been a long time VW owner (18 to date), and had an Audi about 10 years ago, but was so frustrated with the repairs and dealerships, that I stuck to VW.

Bought my 16' S3 this summer up here in Canada, not even half way through it's bumper to bumper warranty, traded in my very clean 15' GLI. within weeks of buying the S3 I noticed front wheel spin, which is exactly why I wanted an S3 - to have awd/traction.

Did a bunch of mild mods, stage 2 tcu/ecu tunes, ended up getting worse, got a code, and was basically no awd at all, only fwd. When we did the DP, I noticed the rear coupler was warped and chewed up, so I booked it into Audi.

Long story short, the audi dealership flagged it TD1, and refused to fix any of the issues I had with the haldex , as they diagnosed not only a clutch assembly failure, but pump and controller as well.

To make things better, the service advisor refused to fix my auto headlight issue, stating 'once a car is chipped, you basically have no warranty'. This infuriated me, as I have worked for VW twice, and know that your warranty isn't completely gone from a damn air/fuel tune. Oh, and they tried to sucker me into a full tire mount and balance. didn't even diagnose my loose exhaust valve.

My car has a K code dif. I used launch control 2 times in the 4000km I've owned it. Im writing Audi Canada to see if theres something that can be done, because an electric controller and pump failing seems to be pretty coincidental. I'm not getting my hopes up that they'll care. It's killed the very short honeymoon I had with this car, and Ill probably trade it off at a loss once its fixed, go back to VW (at least the dealership I normally deal with will back a customer with a mild tuned car ffs)

Its more frustrating there's no upgrade for these parts. Ugh!

1. Since purchasing it (used) noticed front wheel spin, after tune, was excessive and threw AWD Mechanical Malfunction (C111307)
2. 40,000km
3. 2016 S3 PP
4. C111307
5. Nothing fixed to date.

[yeedub]

If it was stock and you showed the code they would have fixed it for you

Sounds a lot like my experience from the first dealership I went to. The TC light was on while accelerating and the tech was saying it was normal due to having 300hp. The second dealership I went to fixed the problem.

1. I was turning from a corner and when the torque was transferred to rear wheels I heard a little punching noise from the rear bottom of the car. It was interesting but didn't feel any torque loss on the rear axle. However couple of days later I heard a terrible metal grinding noise whenever I hit the gas pedal in dynamic mode. It continued every single time I did it. Rear wheels lost torque as well.
2. 18.000 km
3. 2016/April S3 Sedan (Last series of non facelift)
4. There wasn't any error codes
5. My car is still under warranty. I took it to the AD. While examining, in the first day they found a water coolant leakage. Replaced that part under warranty. Afterwards it took a week to diagnose the Haldex problem. They said it was the Haldex coupling (Part #5Q0521307). Now we are waiting for that part to be delivered from Germany, 10 more days!

When I checked under the car, they showed me the coupling. Yes it was broken, the ring shaped metal cover was all shaky and the inside was literally chewed. However they said they are not %100 sure if this is the only problem. They believe it will fix all the problems regarding traction and the noise but "there is always" a chance that could also be something else besides the broken coupling.

I uploaded the live image photo that shows the broken part.



I will keep it updated after I get the car back.

I would really appreciate the comments if this broken coupling would really cause that grinding noise and traction loss. I hope this doesn't last with a Haldex change.

[Hites]

I don't know if this has been said before, but it seems like the "pump failures" are likely caused by the filter blinding and then cavitating the pump. Has anybody had the symptoms of a failed pump, removed their pump, cleaned the filter, and then reinstalled the suspect pump?
I'm curious if the pumps are failing due to cavitation or if they just seem to have failed.

[VDubLove]

Just got my 2015 CPO S3 back from the dealer with a Haldex traction concern. The traction control lights up every time the car is driven hard from a stand still and when ESC is off it appears as though the rear is not engaging at all. The car has new Continental summer tires on it and every time I have driven it hard has been in the dry.

My SA tells me that they test drove it numerous times and were unable to "replicate" my concern. I have a pretty good relationship with my SA, as this is the second Audi I have taken to this dealer for service. I would like to believe that she is being honest with me and not trying to get out of a warranty repair somehow.

The car has 29,xxx miles on it and is, according to them, not throwing any codes when scanned. I think the next step is to have a tech drive or ride along with me so he can experience what I am experiencing. Judging by what I've read on here, most people seem to have a similar experience to mine.

All I know for sure is that something is definitely wrong.

Dealers are idiots. Do a launch and show them you are fwd.

So my Haldex Coupling is replaced under warranty but there is still no traction on the rear axle. I'm going to leave the car to the service tomorrow. It'll be good to hear your suggestions in order to confirm the actions of the service. Thanks everyone.

May sound stupid, but did the dealer confirm that the pump is functional?

Nope, still not. Is it normal to face this issue when car is 2 years old and only on 18k km?

I discovered this issue on my car right after I bought it (used). It had done at that time around 24k miles. So I’d say yes.

I think it’s about how often you engage the Quattro. So it’s always on your driving style. All or most issues starts with a clogged oil filter. They look terrible.

This is pretty much exactly what my coupler looked/felt like, that led me to bringing in the car.

All warranty denied from being flagged td1, and was told my clutch assembly was fried, and needed to be replaced. Quote for everything, was $6800 cdn.

I wrote Audi Canada 2 weeks ago, to voice my concerns that these parts are known for failure, regardless , how could the dealership tell me ALL of my warranty was void on a 2 year old car with 40k left of warranty...

No reply from Audi yet. On Monday I will be calling them.

Please confirm that what you're saying is that the root cause of these haldex issues could be the pump filter blinding.
Thank you.

[maskari_gti]

Pictures aren’t mine.


I can’t say it’s 100% the cause but see how nasty the filter could get.

Really dumb question on my part and I’m prepared to be pummelled with tomatoes however if the Haldex unit fails does that mean the stability control no longer works?
I don’t believe we have the Haldex issue in both vehicles however I’ll be requesting if they can inspect the filter and drain and replace given the fact my car is due for its scheduled maintenance in the next few days.

Here is my update!

My authorized Audi service told me that my whole haldex unit was faulty and needed to be replaced (over $5,000). I requested the fault code but they didn't tell me any code and I decided to take the car to another service. Looks like there wasn't anything wrong with my haldex, it was only front bevel box which transfers the power to the shaft. I'm shocked how they detected it wrong but its fixed now.

Always keep in mind that front bevel box can be broken easily, unfortunately this is mostly caused by launch controls.

So its not always your haldex that gets broken... I hope this helps people that have rear traction issues.

Read this on facebook, but maybe you guys can give this a try. Use a vagcom or OBD11:

(22) AWD -> Basic Settings -> Pump motor

Run the test with the engine on and let it run until it says done.

[BJustinR]

Purchased a 2015 S3 prestige @ 27k Miles. Brought it in to my Audi dealership just to do an inspection. Love my SA, I stated the haldex issue from this forum. They said they heard of it on their Audi Forum. I said I Never performed a launch but I only wanted the haldex to get inspected. I told them I smell coolant as well.

About three hours later, he called me back and said the haldex pump will be replaced and the radiator was leaking so that’ll get replaced all under warranty. SA said I can get my car back tomorrow since I’ll parts are in stock.

[TwoLeftFeetMatt]

Sorry to hijack the post with a personal question, but would you all even consider buying a used 2015 S3 with 50k miles on it, or is the Haldex issue really that prevalent? As far as I know, I cannot check how many times the original owner used LC. I do plan on getting an ECU tune and possible a TCU tune as well. I would be purchasing it through a used dealer and not Audi themselves. Considering the extended warranty too. Thoughts?

I don't think the failures relate to how many times its used LC. On our R we have done 1000's of launches and didn't have issues.

Well looks like my haldex is shot on my 15 A3 at 41k. Replaced the haldex pump and all since it was fairly cheap along with the fluid. The excessive wheel spin still persists, and the C1113 07 code is showing on vag com. Car is Uni stage 2 debating on whether to bother with the dealer or just buy a used diff.

Just had my first experience with some crazy front axel wheel spin. Launched and it didn't catch for over a whole second. The car only has 6,600 miles on it but it was raining out too so I'm not sure what to think here.

My haldex stopped working at around 50k miles. I replaced the haldex pump and fluid (very easy job for any DIYer's) and the problem persisted. Took it to the dealership, explained what happened and what I did to resolve the issue. The transmission ended up having to be reflashed and reprogrammed (my car is completely stock), totaling $147. At 79k miles now and still working like a champ.

Thanks for this thread. I’ve only had my 2015 S3 for 45 days. What is the best way to test for a Haldex issue? I floored it from a slit roll goi g up a slight incline and got a decent amount of wheel spin. Should this happen in any condition or setting? It was 25 degrees outside. Any advice for testing is greatly appreciated.

Thanks

You should get zero wheel spin, unless your making at least 600 wheelhorsepower and 600 wheel torque.

If there is a wet patch you could set your tires in, launch it out of there with launch control. If your tires slip more than a second or two, I'd have someone record the wheel spin from the out side of the vehicle.

Go in and let them you that your AWD car should not be exhibiting wheel spin at any speed, you looked into it and through the forums there seems to be documented evidence of the issue with S3s and a technical service bulletin to replace parts to alleviate the wheelspin problem.

My advice would be to ask for a tech to do a ride along with you so you dont get the "unable to duplicate customer's concern", meaning that they cant seem to find the issue.

This way you can show them the wheel spin issue yourself. Also, if they try to say its normal, let them take out another S3, preferebly a facelift model that does not have the issue and let them prove to you that its normal.

Good luck.

Thanks so much! I’ll try launching the car with TC on. I’ll also try the LC with the TC completely OFF and see what happens.

That makes complete sense. I’m going to make sure it’s a for sure issue first but I feel like there is an issue. I’ll come back after further investigation.

Thanks!

[ccoop6]

Today was the perfect morning to try the haldex. It was wet outside, I turn traction control off, launch the car and the front wheels spun like crazy with minimal push from the rear. Time to go to the dealership.
