Engine Stall problems of the 2016 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.
