Engine Stall Problems of Audi S6

Oil screen interior of engine (non-serviceable) clogged which prevented turbo chargers from receiving oil. Both turbo chargers failed which causes engine to stall. Was driving at 25 mph on two lane city street. Engine died, power was lost, and steered vehicle to avoid collision with brick mailbox. Brought vehicle to a stop in roadway (no shoulder) but was blocking traffic. Car would not restart. Towed vehicle to Audi dealer who diagnosed turbo failure from clogged oil screen and presented a $12,732. 74 quote for labor and replacement turbo chargers. Dealership noted that this is common failure with stock and turned cars and they perform this replacement multiple times a month per Audi TSB. . Read more...

Power significantly reduced. Clear loss of boost. Eventual complete engine stall. I was fortunate to have been pulling into a parking spot when the engine cut off uncommanded. The car had to be towed to a repair shop. It was later determined the turbos had failed due to a loss of oil supply. The oil supply is cut off due to the singular turbo oil screen being clogged. Regular oil changes are documented at correct intervals. Audi after the middle of my2016 installed a revised turbo oil screen to help prevent this from happening. It is a known fault at Audi and should absolutely be a recall to replace the oil screens with the revised versions. It is a major safety issue when the engine can suddenly stop running at any speed.

2013 S6 with 64k miles suffered turbo failure while driving. The engine stalled while driving and stopped in the roadway. Numerous restarts were attempted before it finally restarted and allowed for a short drive to get off the roadway. This is not an isolated incident and there are numerous similar failures with the Audi 4. 0t engine. Audi is aware of these failures and has issued tsbs that identify the turbo oil supply line filter as the culprit but they have not issued a recall. Had this failure happened on a highway at speed it would have been very dangerous.
