‘13 s6 questions

[Jamies6]

New to Audi’s and this forum-recently finished up my 2013
Mods:
Roc euro Intakes
Apr Down pipes
Awe Exhaust
H&r ETS Suspension lowering system
Apr cooling system
Apr tcu upgrade
P3 multigauge setup
XLR8, a local shop, sent my stock turbos out for a drop in “hybrid turbo” they were working on, claiming this hybrid turbo setup makes +90hp vs oem rs7 turbos, yet spool like stock s6 turbos. This included new internals and larger compressor & turbine wheels with machined housings to accommodate. Never did get the specifications on the new larger compressor & exhaust wheels. Dyno numbers were less than rs7 upgrade numbers.
High pressure fuel pump upgrade
Michelin pilot sport a/s 3+ tires

Car was tuned for pump 93 & 100 octane by ACI dynamix, here in CT. Very happy with them.

Moving on, the car moves good. Haven’t been to track yet. Having issues with wheel spin on launch, I will lower tire pressures & play with rpm launch. Comfort mode helped some.

Car also started breaking up slightly around 5200rpm 5th & 6th gear. Plugs were due for replacement so had them done anyways. Problem persists. I then got the high pressure fuel pumps upgrade and a fresh 100oct tune. After some testing this weekend the issue still persists. Wot, higher rpm 5kish in 5th & 6th gear. I will be contacting my tuner to see what he has to say. Until then, any ideas? Hoping it’s just a tuning issue.

Not hating on your tuner ,but these cars are hard to tune,I recommend APR.

No problem man, but I’m confident with my tuner. I should have specified my wording “breaking up” as more of a small hiccup, not so much your typical true harsh break up some may think.

Sounds like you have a pretty badass stage 3 S6. The hybrid turbos you got they are +4mm over the rs7 turbo spec or...? Confused on what you mean by dyno #s lower than RS7 upgrade #s. Im actually in CT too (from Stamford, now in Hartford) and been to XLR8 for work in the past including APR stage 1 on my 13 S6. Looking into going stage 3 in the future but curious what you paid all in for that work. Also ive heard of ACI Dynamix before as a reputable tuner but as above stated our cars are hard to tune and im very happy with APR about a year in. Feel free to shoot me a pm.

Thanks. I had apr stage 1 tune too in the beginning. Was happy with it. The hybrid turbo specifications were never given to me, & the car with these turbos does not make rs7 turbo power numbers.

Car going back on the dyno this weekend for some tweaks.

[Jamies6]

One of the turbos blew on the dyno this weekend. Oil screen clog/failure. Rs7 turbos coming.

[15 Phantom S6]

Did you and your shop not know about the oil screen issue when swapping in the first set of turbos?

Yeah thats ridiculous, XLR8 claims they know their stuff and ive had convos in the past about a possible stage 3 build with them where I vaguely remembering them referencing oil screen replacement as a necessity. If they did forget to do that its a shame. In my personal experience with them there is a very strong possibility they accidentally left my car on the 104 APR stage 1 file instead of 93 which accelerated the wear on my timing guides/adjusters and caused a failure soon after. My new shop found out the car was on the 104 tune after the guides and adjusters were replaced and now the car runs better than ever now that we have switched to the correct 93 oct tune and no more knock sensor codes. There was also a time they did a oil change and when i got home the oil level was at the halfway mark......nice guys but I no longer trust them with my car unfortunately.

[Jamies6]

Screens were replaced @ xlr8, two years ago during turbo install. This car is driven daily in the summer, and it’s driven hard. I’ve known about the oil screen problems, sometimes it just happens. I’ll know more once new parts come in and the turbos are removed. As far as xlr8 goes, they did their part in installing parts correctly. However my whole experience with them & tuning wasn’t as pleasant. When I got my car back from them it was slower 0-60 & a mess with codes. I requested they take the car back to fix codes & tune, they declined & said they would tune it after all codes were fixed/cleared.

After getting the codes ironed out with ACI, they tuned the car & I’ve had zero issues with it until the oil screens started causing a hiccup in accel high rpm and surging on decel. This is why I brought car in as my tuner is in state for a couple days.

I had a funny feeling about my tcu and when I dropped the car off Friday I asked them to double check and make sure my apr tcu map was still loaded. Next day called and said my apr tcu map was overwritten with an EPL tcu map (@ XLR8, who never mentioned that to me directly). ACI then re-uploaded the apr tcu map & the car picked up 100hp. Next pull turbo went.

XLR8- Good shop to have here in CT in a pinch, great communication, but I’m much more comfortable @ ACI.

How many miles between two years ago (the screens replaced) and now?

20k miles?

Did they put in the new rev C check valve and rev G screen, when they replaced it?

You know after I posted i went back to my records to double check to see if my memory served me correctly- As I instructed them to replace any and all essential/needed seals, gaskets parts etc. that are prone to failing, leaking etc. and trusted them to do so. I know the pcv valve was done.

So I pulled out my invoice, I have a long list of seal rings, gaskets, throttle valve seal, cooling vent tubes, oil return tubes listed on my invoice as well as a line that says they did replace the “turbo PCV R&R” is r&r short for rev c check valve & rev g screen? I sure hope so. Lmk. Thanks

20kish is about right. 10k a summer/fall

r&r is short for remove and replace.

so, they removed and replaced the PCV.
The screen is completely different part than the PCV. if its not listed, either as a work item, or part number....its wasnt done.

So you went to a shop for a turbo upgrade and they don’t give you specs of the turbos they are installing and once tuned, it doesn’t make tuned RS7 numbers (so you were their guinea pig?).
You get your car back with codes and it’s slower so you go back to get it rectified and they refuse to do anything until YOU fix the engine lights (they are a shop that works on cars for a living and they won’t look at your car?? WTF!!)
You subsequently find out they put on an EPL TCU tune without your knowledge or permission
It appears they didn’t change the known problematic oil screen and check valve when replacing the unknown spec turbos and then the turbos die (R&R is short for repair and replace).

How can you still say they are a good shop based on your experience? “Great communication”?? They didn’t give you the turbo specs and they didn’t tell you they installed a TCU tune on your car… You basically went there in good faith to upgrade your car, but received a slower and less reliable car that ended up needing thousands of dollars in totally avoidable repairs..

Anyone or any shop can make mistakes and things do happen but its the corrective measures and aftercare that separates the good from the bad.

-yes, however they were clear it wouldn’t make rs7 numbers, but a gain in low end tq and some hp. That setup, their maps and all 525/610 on a mustang dyno.

- Yes. After about 50 miles codes flashed up. Called and yes, they said they wouldn’t touch it until I fixed the codes. I was just as dumbfounded then as you are now.

-I did give them permission to move forward with any necessary EPL tuning software, I didn’t know the TCU would be changed. Even if they mentioned it in person, I would have obliged in trusting their judgement in said tcu map that it would aid the car in making more power. Not the case, apr tcu map loaded and car made significant tq gains.

-I will call them to confirm, but as of now, no, those parts were not listed on my invoice. I’m going to go ahead and say they were not replaced. They did replace the the PCV. What a shame. **Would it be better for me to replace the valve and screen with the revised part, or just remove the screen altogether?** I’ve read up on it, still thinking about it though.

The communication was great, I stand by that. Someone always answered the phone when I called. Constant email updates regarding the status of car. Going in for work, almost done, done ready for pick up, invoices sent prior to my payment etc. Car was delivered on time as well, which I was very pleased with. In my experience, not all performance shops operate like this.

I’m not really the type to hop on the internet and shit on shops. More of a lurker than a poster. I really just wanted to post with a few little issues I was having & hopefully gain some insight & see if anyone else has experienced those issues.

Rs7 turbos ordered. I will also be replacing the PCV valve, previously mentioned check valve, possibly the screen & a new set of plugs. Anything else I’m missing while everything is apart?

Thanks

dont waste your money (~$250) on another PCV valve. just remove and replace with the same part.

replace oil screen and necessary gaskets - about $150 worth of parts and 8hrs of time.
spark plugs are probably around $125. should be replaced to match the requirements of APR tune.

its really a shame they didnt replace these parts when they replaced the PCV the first time around. you're about $4k in the hole because of their negligence to replace a known weak point in the engine (Screen).


i dont think your missing anything else to do at this time, but you should consider some cooling mods in the near future.

[youngsolodolo]

Weird that they put an EPL tune on your car instead of APR. They are an authorized APR dealer yet they chose to use another companies tune with the new turbos....super sketchy and does sound like your car was their guinea pig. Also you mentioned they installed the hybrid RS7 turbos which with the correct running should be higher than RS7 stock dyno #s and just under stage 1 rs7 #s. Will ACI dynamics be installing the new turbos on the car along with the new screen, etc? I was under the impression they were only tuners and id love to take my car to them in the future if they do these types of jobs at a reasonable price.

Not hybrid rs7 turbos. Just a set of hybrid turbos that would be larger than stock. Yes they were clear that this setup was an alternative to rs7 and I would be the second owner testing them, we spoke about power gains and price. At the time I figured it would be worth it if they worked out. The setup did make good numbers with an apr tcu map, race gas & a very capable tuner. When I called today for turbo specs they replied with a “proprietary setup” and did not give me any numbers or measurements.
When I asked about the screen they told me the screen revision bulletin was released nov. 2018. My work was done March. 2018. They are saying they didn’t know about the screen issue until Audi released the tsb. So no, screen wasn’t replaced.

ACI does all my work & tuning since 2018. They have put hours into my race gas file. Awesome set of guys down there. Give them a call, they’ll work with you.

TSB "Engine difficult to start, turbocharger damaged V8 4.0TFSI" November 28, 2018 was the 5th revision, but the new screen (079115175G Oil strainer) was listed in revision 2 November 21, 2017

TSB (rev2) 2044640/2 November 21, 2017, listed these replacment parts:

079103175C Check valve
079115175G Oil strainer

These TSB revisions also listed the same screen (oil strainer) & check valve.

TSB (rev3) 2044640/3 May 14, 2018

TSB (rev4) 2044640/4 May 22, 2018.

TSB (rev5) 2044640/5 November 28, 2018

[15 Phantom S6]

JamieS6, Let us know what they say when you tell them the TSB was out 3-4 months prior to you coming into the shop...

It's your car and situation, but I'm curious to your thoughts on if you still think they have resolved this situation properly? Knowing what you know now, are you ok/happy with the outcome?

Picked up car this evening. Awesome turn around time. Big difference with the new turbos. Looking forward to getting out to the track before it closes for the year and get some times & now that it’s nice and cool at night, maybe some grids races / fun runs.

[Quattogang58]

I have an S5 B8. But I’m thinking about getting an S6 or RS5. But I’m curious to know if I could direct swap just the turbo cores out of the S6 to RS7 turbo cores. Just because the standard S6 turbos are not reliable. Or would I have to get the entire kit?

[goldenzrule]

Another alternative for CT folks is The Shop in Stratford. Jimmy and his team have done some amazing builds
