2013 Audi A8: won't start

Filed Feb 17, 2022 · Engine · SC

On the afternoon of September 12, 2018, my 2013 Audi A8L 4.0T started with somewhat of a rough idle, but no warning lights or error codes were present on the dashboard. I owned the car for approximately 18 months at that point, and this had never happened before. As soon as I started to drive, the tachometer became steady and there were no other indications anything was wrong, even stopping at traffic lights the problem did no persist nor were there any indications anything was wrong. Once back in Spartanburg, the car stalled while slowing down for a traffic light. The engine cut off completely, the steering became very rigid, and the Check Engine light turned on. I was able to coast to a stop and turn on my hazard lights, and then tried to restart the car to no avail. The engine would turn over, but the car would not start. Another car stopped behind me, and we were able to push the car onto the grassy shoulder out of traffic, which was dangerous in itself but safer than sitting in the middle of a busy road. I had the car towed to Steve White Audi in Greenville, SC. Once there, they informed me that the error codes indicated that both turbo's failed simultaneously and the failure of those turbos caused the first set of downstream catalytic converters to fail also. See attached repair report and payment receipt = $10,975.57 for the replacement parts and labor ($12,070.85 including the 115,000 mile service). Once they told me the cost of the repair, I called Volkswagen USA corporate headquarters to ask if there were any pending recalls for the turbos. Multiple message boards and FaceBook pages go into detail about how the turbos are a known point of failure on the 4.0T cars, and the astronomical cost to replace them. I was informed by Volkswagen that there were no pending recalls, and that I would have to pay for the repairs out of pocket, which I did.

After exiting the highway the car just stopped running. There was no warning and all power was lost. Engine would not start up and vehicle had to be towed from the road. It was at night and the car stopped dead at an intersection (safety). We are grateful that the problem did not happen on the Ohio Turnpike we just exited. There was a clunk sound before it stopped. I suspect the turbo let loose. This has not been confirmed yet by the dealer. There was no warning. Consumer stated vehicle has been repaired.

As a slowed to make a turn in an intersection (downtown in a major city) the car started jumping and then the engine shut off in the middle of a major intersection and the steering locked up. I turned on my hazards and luckily no one hit me, but the car would not start up. However, one I gave it some gas while starting the ignition it turned over, but the car died two more times before I could safely park it. I took it to the dealership and they told me my turbos were blown. My car has less than 60k miles, well maintained, and it's only been used as a commuter vehicle.

Driving with my 3 kids on the highway, the car lost power and stalled. Wouldn't start. After research, found out I was the next in a long line of folks with a 4.0t engine turbo failure. Audi has a tsb but the issue stems from faulty engineering of an oil strainer. Car has full dealer maintained service records. Bought the car used from a dealer. Failed less than 500 miles after purchase. Mileage is 82000. Please help hold audi accountable for a known safety issue affecting all cars with the 4.0t.
