As I was pulling off the interstate to use the restroom, my engine lost all power. I lost control of power steering and power brakes while in motion. I was able to come to a complete stop at the stop sign. I was able to restart the car temporarily and enough to pull into the gas station right off the interstate. I did not think there was anything wrong and went to use the bathroom. When I came back outside to the car it would not start. I had to use my insurance company roadside assistance to have the car towed to an Audi dealership. The Audi service department informed me that I had a turbo failure. There was scorching present when the sr tech viewed the turbo with a borescope. The car is known for this issue and hasn't been recalled. There are 2 tsbs that are related to turbo failure for these cars, tsb2044640/9. thank goodness I had an extended warranty. I will have 2 new turbos, a new oil screen and PCV due to this issue and that is a 5 figure cost.
