Engine turbocharger experience catastrophic damage, engine stalled, power steering was disrupted.
The car was running rough for a couple weeks; hesitant to accelerate, failed to start multiple times and idled rough. One day I was coming home from my hour long commute, I put the car in reverse in my driveway and the car started bucking so badly that it became un-drivable. At this point we had to get the car towed on a flatbed an hour away to the nearest dealership and this is when we discovered that the turbos had gone bad. There was no check engine light or any indication before it just failed. I am active duty in the united states coast guard and being without a car is not an option. Because of the shipping delay and waiting for the turbos to come from germany, I was without my car for two weeks. I was loaned a vehicle but I had to rent a car for one day in between. We have been told by Audi dealerships for years that this was a known problem and to expect this $10,000 repair.
Turbochargers failure due to clogged oil screen. Had to replace both turbocharger with new units and replaced oil screen with updated version.
While driving, the car started to run rough and wouldn't idle when I came to a stop. It became very hard to start, especially when hot. While the car was in for recall work it was diagnosed with bad turbochargers. Quoted over $10k in repairs.
It if very well known issue for 4. 0tt v8 Audi engine, there is pour oil supply to turbos which causing them to fail. After an hour of cruising on highway car would choke on idle, difficult to even start. Audi dealer diagnosed turbo failure without underline cause. 10k dollars repair every 20-50k miles is unreasonable due to fact that oil separator, oil strainer, seals and coolant lines have been identified to be defective and updated by manufacturer (Audi).
Car has 3 bent rims and a broken motor mount carmax will try to say they fixed rims and the motor mount is fine.
