“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.”
