My specific year model 2014 as well as all 4. 0tt models 2013-2014 have a well known issue in which, by faulty design, the oil supply to the turbos is restricted therefor causing the turbos to fail. The flawed design is in relation to the oil screen that clogs and starves the turbos of oil and causing failure. Audi has since began installing a revised version of this screen to alleviate these issues in models after2016. But they have ordered a recall for year models 2013-2016. Even with service intervals cut in half(oil changes at 5,000 miles instead of 10,000 miles) it is still a very common issue. When the turbos fail the engine is unable to run and can pose a serious danger to the driver as well as other motorists on the road. Not only is this a real and serious safety hazard, the cost of the repairs to replace the turbos(due to a design flaw) is upwards of $6,000 conservatively. Audi has released an extended warranty to cover the repairs of the oil separator to 100,000 miles, but this only addresses part of the problem. Many times by the time the oil separator is flagged by the ecu, the damage to the turbos is already done. On top of that if the turbos fail due to the oil separator or due to the oil screen clogging, the only repairs and costs covered under the extended warranty are for the oil separator itself. For example, if my oil screen clogs(which leads to no cel) or if my oil separator fails in turn causing to turbos to fail, the only thing covered by warranty is the oil separator. The extended warranty also is also only allowed to be used after the item has failed and not preventatively. If these items were to be covered and replace preventatively the turbos would no longer be failing due to this issue. This is a very well known issue in the Audi 4. 0 community. Through Audi forums and facebook groups it is apparent this is not a small issue.

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.

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. . Read more...

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+.

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.

I was driving at approx 65mph on the highway when all of a sudden I lost significant engine power in my vehicle. I tried to accelerate and could not so I pulled over and the car immediately stalled and I had to have it towed to the repair shop. The issue is a result of the turbos in my vehicle are damaged. Mechanic said there is a known issue related to a screen that filters the oil that can get clogged overtime and cause oil starvation to the turbos increasing heat and ultimately causing failure. Audi has released a TSB for this fault with updated parts however these issues continue to plague vehicles like mine that have otherwise been taken care of. The repair costs for this could be upwards of $9k all because of a design flaw. Not to mention this could be dangerous if loss of power occurs on the highway which could cause an accident.

Turbo failure at 62,356 miles. Car has been into dealer for all required maintanence. Turbo failure occurred while driving on the highway with my family for a family gathering. Car went into limp mode and nearly stalled on the highway. I was able to pull off to a safe spot and there was an epc error on the dash. The car would not restart. Towed to dealer, and received a repair quote for more than 10k. I believe there are many other customers facing similar issues and Audi should look into this issue and cover the repairs. There is a TSB out from Audi regarding this. I have contacted Audi of America and waiting for a response from them for goodwill repairs.

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.
