Problem: Volkswagen Group of America, Inc. (Audi) is recalling certain 2013-2017 A8, S6 Sedan, S7, S8, and 2014-2017 RS7 vehicles. The turbocharger oil supply strainer can become blocked, causing wear to the bearings due to lack of lubrication.
Risk: Worn bearings can cause the turbine wheel to contact the turbocharger housing or cause the shaft to break, causing an engine stall and increasing the risk of a crash.
Fix: Dealers will replace the oil strainer and perform an oil change, free of charge. Owner notification letters were mailed August 4, 2022. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 21H7.
