The Mfg defrayed some of the cost of replacing the two turbos but I was charged $5,607.06 on the repair on 9/24/20. The cause of the repair was do the mfg defect and they should pay 100% of the repair. The vehicle only had 42,040 miles at the time of the turbo failure.
Recently learned that my car broke down on my spouse in an extremely unsafe location due to turbo failure(s) probably caused by the turbo oil inlet screen. She was on a busy street when the car shut off on her putting her in an extremely unsafe situation to move the car and wait for tow truck service. The car is still with the Audi dealership for repairs but has been confirmed that this is the likely incident and fixing it will likely prevent further issues. This car has only been to Audi certified technicians at dealerships for the entire time I've owned the car and I was never notified that this is a common occurrence in these models with the turbo. Numerous online forums are dedicated to discuss the common occurrence when researching this particular issue going back a few years, mostly astounding a recall hasn't been issued. There was no warning lamp for the issue to warn us of the impending failure.
Vehicle has had all recommended maintenance performed on schedule at the Audi dealer. Driving down a highway at about 73k miles, engine stopped running with no warning. Electronic systems appeared as though engine was running, but it was dead. We were extremely fortunate that this happened on a rural highway and not the big city freeway system we had recently driven through. Cause of the problem was a total engine failure, later discovered to be failure of the turbocharging system. Checking online reveals that it likely due to a defect in an oil strainer. Sudden catastrophic engine failure at only 73K miles in a dealer-maintained vehicle is a safety hazard, to the occupants of the vehicle as well as to surrounding cars that have to navigate around a suddenly powerless car.
Turbocharged failed while driving in afternoon traffic, leaving car stranded at heavy traffic stoplight until tow could be arranged. Failure occurred while idling at the stop light. Failed turbochargers are available for inspection. Failure was initially diagnosed / confirmed by dealership (Audi Chantilly) but due to extreme cost of repair quoted by dealer, car was transported to an independent garage for the repair. Failed turbocharger was inspected at dealership using micro-camera for diagnosis of the problem. There were no warnings, check engine lights, strange noises, loss of power, etc..; failure was total and instantaneous. Additional information: This is a totally stock vehicle, no modifications or tuning performed. It has never been raced or abused. The 'launch mode' built into the car's design (for fast acceleration from stop) has never been used on this vehicle. Put simply, this vehicle was 'babied'. For the initial life of the car, all maintenance was performed at dealership (Audi Chantilly) under service contact. Upon expiration of service contract (~65K miles) all service was performed by owner. Knowing of the turbocharger oil feed defect present in this model Audi's design, owner increased oil change service frequency to (unsuccessfully) try preventing turbocharger failure. All owner supplied oil change materials (oil and filters) were consistent with Audi factory requirements.
While driving in city traffic, the car went into limp mode with some new lights on the dashboard. Before I could get to a safe place, it completely died and almost caused an accident. I was stuck until I had help pushing the car off the road. Upon reading the OBDII computer codes and then confirming with a professional mechanic, both turbos had blown. There was little warning, and no time to have a safe option once the warning light came on. Upon reading up on this platform, Audi has a defective oil screen that gets clogged and oil starves the turbos which makes them fail prematurely. Hopefully, they will fix this issue moving forward.

With only 53,000 miles on my 2013 Audi S6 both turbo charges failed and Audi is now charging me $9,000 to replace both turbo charges which are supposed to last 100,000 to 125,000 miles. This issue occured while on the road idling at a light and caused the car not to be able to start and to shake the vehicle violently.
While driving on the highway vehicle lost power. Upon exiting the highway, I noticed a rough idle. Next morning vehicle failed to start normally (push to start) on multiple occasions. Needed to press the gas pedal significantly. Brought to independent auto repair shop for diagnostics. Was told oil separator had failed and turbos had both failed. Repaired at my (significant) expense. Vehicle is completely stock. No engine modifications. 93 octane gas. All maintenance as per manual.
After driving the vehicle under normal driving conditions, I arrived at my destination and without any warning or dash lights the vehicle shut off roughly. Since it sounded weird, I tried starting the vehicle back up again. The engine would crank but wouldn't start. The vehicle was inspected by a Volkswagen dealership where it was determined one of the two turbochargers had failed. The passenger side turbine wheel was broken and the driver side turbo was showing signs of the turbine wheel catching the housing. Both turbos were replaced along with the turbo oil screen.
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+.
Engine shut down while on freeway at 60mph speed due to turbo failure. 60,000 miles on engine. Issue caused by oil pickup screen being clogged and starved the turbos from oil, thus resulted in failure and engine shut down.
The turbos on the S6 failed after only 50,000 miles. This makes the car have dangerously low power and nearly undriveable. This is an extremely common occurrence for Audi 4.0tt models, and Audi even issued a tsb regarding the issue to it's service centers. But to date, Audi has not rectified the issue or made contact with those who are out of the warranty period. Blown turbos cause all sorts of issues, including potential engine damage, cylinder misfires, fuel pressure issues, and over-heating. On my particular vehicle, the turbos failed simply by starting the car after sitting in the garage for a few days, undriven. Cost to replace turbos and make repairs is $10,000 to $15,000.
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.
Suspension control arm bushings worn out causing squeaking and unexpected vehicle path during acceleration in all situations. Oil filter under pvc valve clogged and starved turbocharger of oil causing failure.
The turbos on the car both broke at the intermediate shaft before 75,000 miles. The car was cruising on the freeway, and the moment I slowed down to take the exit, the car lost power and shut down. I had to make an emergency stop on the side of the exit with little to no room to pull over.
Turbos are damaged and the dealer said it will cost $13,000 to fix I had warrantee till 120K or 7 years and it happened at 7 years one month and 116,000 miles. Audi of America where not willing to help even though there was grinding that occured two months before the warrantee time. It happened when in motion driving from startup.
