Audi S6 stalling problems

Filed Jul 3, 2023 · MI

2014 AUDI S6- Consumer states " I am writing to file a claim for a vehicle recall on my 2014 Audi S6. The date of the recall is March-20-2022. the federal safety agency Campaign# is 22V‑178. The Audi Recall# is 21H7. The specific defect that is being recalled is Turbo failure. In early 2021, I experienced multiple problems with my vehicle that were consistent with the recall, such as Rough Idling, Difficult to Start, and Stalls. It was fixed at a local Audi dealership in May-2021 (prior to the recall announcement). I was responsible for the repair expenses, which totaled $4198.29, for the Turbo and oil strainer replacement. When I became aware of the recall, I filed a claim with Audi to request reimbursement. Audi's recall website indicates that there are no recalls pending for my vehicle, but the Model Year/Model/Engine/Issue is consistent with the scope of the recall. In over 7 months after filing the claim, I have not heard back from Audi even after repeat inquiries. I would like the federal safety agency's help to get reimbursement from the OEM. Please contact me if any additional information is needed, such as a copy of the repair invoice. Thank you for your time and attention to this matter.

I was driving my car and it stalled out in the middle of an intersection which was totally unsafe and it would barely start. I was able to limp it to safety but it would not run or idle correctly. I had it towed to the local Audi dealership and they diagnosed the issue as being the turbos. The turbos failed and need to be replaced. The obvious known issue with the oil screen starving the turbos and causing collateral damage is well documented hence Audi issued an extended warranty on turbos and the recall on the oil screen however the dealer is refusing to do any repair and has had the vehicle for over a week.

Oil screen interior of engine (non-serviceable) clogged which prevented turbo chargers from receiving oil. Both turbo chargers failed which causes engine to stall. Was driving at 25 MPH on two lane city street. Engine died, power was lost, and steered vehicle to avoid collision with brick mailbox. Brought vehicle to a stop in roadway (no shoulder) but was blocking traffic. Car would not restart. Towed vehicle to audi dealer who diagnosed turbo failure from clogged oil screen and presented a $12,732.74 quote for labor and replacement turbo chargers. Dealership noted that this is common failure with stock and turned cars and they perform this replacement multiple times a month per audi tsb. Tuned vehicles are immediately denied warranty despite there more than 131 reported cases on one owners group/volunteer website (https://www.audizine.com/forum/poll.php?pollid=4500&do=showresults). My vehicle received oil change and 40k service from audi dealership less than 5,000 miles prior to this failure. Oil screen replacement requires 20 hours of labor to tear the engine down to get to the part (non-serviceable) - technical service bulletin 2044640/9 (revised 3 times over 3 years to replace oil screen with upgraded screen - rev g). Have visited with multiple audi dealerships to obtain competitive quotes and learned that it is a common issue with the 4.0 v8 engine with failures normally occurring at 65k - 85k miles in a8, s4, s6, s7 models and that the repair is normally $11-12k per incident.

Having just exited the interstate and stopped at the end of the exit ramp, my 2013 audi s6 started to stall as I was turning onto a secondary road. I managed to pull the car over to the side of the road before I lost all forward power, avoiding traffic in motion in proximity to my vehicle. The car would not restart after a check to insure things such as a proper amount of fuel was in the gas tank. After repeated attempts at starting the car failed, I had the s6 flat bedded to the nearest audi dealer for repair. I spoke to the dealership several days after the incident and they diagnosed the problem as two failed turbochargers. The failure was attributed to the turbocharger oil screen clogging problem. I was told the replacement (parts + labor) would be in the $12,000+ range. I authorized the out of warranty repair as the car was in excellent and well maintained condition and I was not ready to scrap it. The dealer several days later informed me that audi corporate had reviewed the failure and was willing to absorb 75% of the estimated repair bill as the s6 had just come out of warranty and had been properly dealer maintained. Several weeks later I was able to pick up the car with a payment due for repairs (after audi 75% coverage) of $2674.26 with the new turbos installed and the s6 was now running properly again. I now hesitate to use the car for any long trips on the highway due to concern I may have a recurrence of this turbo failure even though the car is being dealer serviced properly at the suggested intervals. Further, I believe this inherent problem has diminished the resale or trade-in value of this 2013 audi s6. I was forced to rent a car for several days to return home after this failure which in total cost was $500+.

Power significantly reduced. Clear loss of boost. Eventual complete engine stall. I was fortunate to have been pulling into a parking spot when the engine cut off uncommanded. The car had to be towed to a repair shop. It was later determined the turbos had failed due to a loss of oil supply. The oil supply is cut off due to the singular turbo oil screen being clogged. Regular oil changes are documented at correct intervals. Audi after the middle of my2016 installed a revised turbo oil screen to help prevent this from happening. It is a known fault at audi and should absolutely be a recall to replace the oil screens with the revised versions. It is a major safety issue when the engine can suddenly stop running at any speed.

Both my turbos failed on my car on christmas day in 2019. I was coming home from dropping off my daughter 90 minutes away. After leaving the highway and starting to move once the light turned green, my car decided to completely stall. I was able to pull over the to shoulder as I was coming to a stop as I was on a one lane road. My car was towed and it was determined that my car had both turbos fail. I received my car back a month later and since then have had a coolant loss issue as well as a surge issue. The coolant loss issue requires me to put 4 ounce of coolant into my car every morning. I reported this issue to my audi dealership when I got my car back but it hasn't been fixed. I'm unsure if the coolant issue is what caused the turbos to fail, or parts of my turbos propellers went into my engine or someplace else which is causing issues with the car. Furthermore, the car now surges when coming to a stop. The car will surge a foot or two after it's come to a complete stop which is dangerous. Both these issues can be seen on message boards at the following site: https://www.audizine.com/forum/showthread.php/808057-4-0tt-blown-turbo-poll as you can see it's a bigger problem than just a few cars. They are ranging from 10% to 40% blown turbos depending on the year.

My turbochargers failed, which I understand is not uncommon with this engine. It was driving normally. I stopped for an errand and it restarted with great difficulty. I then drove some additional distance and it stalled in traffic. It stalled repeatedly whenever the RPM's fell below 2000. I ended up running a red light, to avoid slowing down, knowing it would stall. Fortunately, I was in an uncrowded area. It looks like audi has already issued a technical service bulletin regarding the propensity for turbo failure. I would like to see more than that happen.

Turbo failure - car stalled while slowing on a major road. Audi is aware of the issue and the dangers of the failure, but has not issued a recall, even though they have issued multiple technical service bulletins regarding the issue and admitting to faulty parts causing the failure. It is only a matter of time before someone is injured or worse due to losing control of the vehicles acceleration and use of engine.

Vehicle was in motion when it started shaking roughly. The car stalled and wouldn't turn back on. I had it towed home and was able to diagnose seized turbo compressors. Replaced the turbos which fixed the problem but at an enormous cost.
