2015 Audi S7 problems

“My turbochargers failed due to oil starvation caused by a clogged oil screen. My vehicle had 71,393 miles on it when the turbos failed and had no prior problems or warning lights. While driving to the dealership for a Passenger Occupant Detection System recall (unrelated issue with no warning lights), my car lost power in traffic as I was pulling off the main road into the parking lot. Luckily I was able to coast most of the way to the service entrance but had to have the car pushed the rest of the way. The electronics still worked, the car would simply not turn over. I was very lucky that I was not on the highway or other major road when I lost power as there was absolutely no warning or signs of trouble: the engine simply stopped. The car has since been repaired by the Audi Raleigh dealership, but they were an absolute nightmare to work with and took forever to diagnose the problem. I believe there is a well know service bulletin related to this issue for this engine, but no recall has been issued. I also believe there is an open NHTSA investigation and I would like to help in any way possible.”
