CarComplaints.com Notes: The 3rd generation A8 got off to a slow start. Really slow, like "limp home" slow thanks to leaking antifreeze frying the engine's control modules. Thankfully the problem was recalled in September 2016.

FAILURE BOTH TURBOS Purchased Audi Naples Jan 2018 Maintained at Audi Ft Myers Audi While on a vacation from our home in Florida to New England our Audi A8 experienced a major turbo failure while on an Interstate highway. On 8/6/21 I was traveling in the middle lane of I495 at 65 mph, when traffic slowed, the car stalled. With cars passing me on both sides I eventually managed to get the car started and made it to exit 15 (rt44) going toward Plymouth, MA. This truly was a scary situation, waiting to be rear ended. While on rt 44 it died again in traffic. I managed to make it into the breakdown lane. At about 2:55 pm a state Trooper stopped and asked if he could help me get to a safer spot but by that time I had called AAA. At 3:30pm AAA arrived and towed us to a safe spot. At no time before, during or after this failure did I receive any message or warning that this failure was imminent. The car was taken to Audi Norwell and diagnosed with defective turbos due to failure of turbo shaft bearings. The screens were clogged preventing oil from reaching the bearings. The turbos were the original equipment. I have read in the Audi Forum this is not an uncommon problem. I understand the screens have been redesigned as a result.

I had a strong gas smell. I checked internet and read, 2013 Audi A8 (Volkswagen) is recalling certain 2013-2015 Audi S8 and A8 vehicles. The fuel supply line for the high pressure fuel pump may become porous over time, resulting in a fuel leak. It could cause fire. Action need to fix it: Audi will notify owners, and dealers will replace the fuel line, free of charge. When I notified flow Audi in greensboro, nc, they said they would not fix it. They told me to contact Audi America. What do I do?

Driving at speed limit on us highway in heavy traffic in the near northern suburbs of Chicago, experienced sudden loss of power. Vehicle began running very rough and eventually stalled in left lane. Sudden lack of power, stall and unanticipated loss of speed nearly caused accident and did cause major traffic back up. Vehicle was towed to local shop. Diagnosis determined cause of sudden power loss was damaged turbochargers (X2). Turbo impeller bearings were completely destroyed due to lubrication starvation, which caused disintegration of turbocharger impellers. Shop indicated this is a known problem with the Audi (vag) 4.0 twin turbo V-8 engines. Supporting this notion, the dealer had the turbos and associated repair parts in stock (over $6,000 of parts). Vehicle is meticulously maintained by certified Audi dealer. Vehicle indicated about 63,000 miles on odometer at time of incident. Vag uses this engine in several models across the Audi line: S6, S7, RS7, A8, and S8 (some modifications between some models).

Depressing accelerator at first failed to move the car; then it surged until braked; then it failed to move the car on the next depression; again followed by a surge. This happened as I was turning into a lane of oncoming cars where I had plenty of time to make the turn safely but that time was chewed up trying to get the car moving. The exact same thing happened again except this time I expected non-performance and waited 2 or 3 minutes for all traffic to stop at a light. Then the same thing happened again. There is no doubt this could lead to a fatal crash.
