What 2014 Audi A8 owners say
Engine & cooling
Turbos failed. Was traveling home on a highway, when i pulled off the engine suddenly stalls out and loss of steering occurs as the engine system automatically puts you in park. Switching to neutral leads to a very 'leaden'/heavy driving feeling (Kind of like with no Power steering, but a little better). Able to get it restarted again with some effort. Car will stall out at any point in time when RPM is 1200 or less (you have about .25s to get it back out of that range or it stalls again). Power is sluggish. To avoid stalls, shifts must be rapid and neutral-shift+gas needs to be applied to prevent RPM from being below 1200. Made it home safely, but had it towed to dealership. Dealership notified me that it was a turbo failure, both impellers have become lodged in the side of turbo casing and are stalled out. Nothing preceded this; no engine lights or anything. …
My Audi Certified Preowned A8L, 4.0 TFSI suffered a complete turbocharger failure without any notice. The car went into service 9/30/2013. I purchased the car from the same dealer that originally sold the car in Stratham, New Hampshire on 12/26/2016. I purchased an extended warranty from the dealership for 8 years, 100,000 miles. Thus, the extended warranty expired on 9/30/2021. Car has always been serviced by this Audi Stratham Dealership. During a routine trip, car stalled, went into neutral upon entering a stoplight/intersection and would not re-start. Had to be towed. No modifications ever made to this vehicle. Recently had 75,000 mile service interval completed by Audi. Car now has 81,000 miles.

Fuel & propulsion system
For technician report, go to: https://getpe.co/4ZT0j2 While driving on a major central NJ highway, slowing to exit, the vehicle shuddered and stalled in lane. The engine EPC light came on and a message to put the car in park to start the engine followed. This made it impossible to move the car off the road. It was necessary to stand behind the vehicle and wave traffic around. A passerby was able to get the car started and moved it off the exit and to a service road shoulder. The car shuddered and died again. Traffic was heavy and the situation was quite dangerous. The car was taken to the dealer. The turbocharger impeller shaft and fins were damage. Please see above link. Also, please see Audi Technical Bulletin 2044640. This is not a unique event.
Car went dead on the hwy without any warning. Dealer has the vehicle for a month now and says there is metal shavings in fuel and need more than 15000/- in repairs to replace fuel pump, 6 fuel injectors fuel line and fuel rail. Metal shavings come from fuel pump Failure there should be micro filters in line to stop them from entering the fuel line and injector with sudden death.
