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

While driving on the main highway, my car engine shut off. I had dysfunctional brake and steering failure. Brake was hardly working and I had to use all my strength to control steering. Basically, while driving at 50mph, car engine shut off without warning and I lost steering and braking. I was able to pull off the road into a vacant parking lot and car came to a stop. Fortunately, no cars were around at the time. Otherwise, I along with my family would have been involved in a potentially fatal accident. My car had been serviced by Audi since purchase. It was just serviced within the past month. Car was towed to an Audi dealer--the turbo charger had failed. Based on the dealer description, failer of turbo caused the catastrophic failure of both the steering and the brakes. There sho

Both turbos on the engine were damaged to the point of replacement, causing the car to stall out at idle at a busy intersection putting me in danger of an accident. My car had less than 50,000 miles on it. *tr

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)

While on the highway, I noticed that the car was not picking up appropriate speed when accelerating. There was no prior notice or engine lights or any abnormalities with the vehicle prior to this. I decided to pull off the highway at a rest area and as the car was slowed down around 15-20 MPH, I lost total power of the vehicle and was unable to steer or use the brakes. Luckily the car was able to coast to a stop without injury but was extremely frightening with my family in the vehicle. After tow to the Audi dealership I was informed that the problem was a catastrophic failure of the turbos in the engine. I did extensive review of this problem and find out that it is a known problem and boils down to a design flaw where a small oil screen essentially starves the turbos of oil. Sometime the
