Audi is recalling 26,053 model year 2013-2017 A8s, S6 Sedans, S7s, S8s, and model year 2014-2017 RS7s.
The turbocharger oil supply strainer can become blocked, causing wear to the bearings due to a lack of lubrication.
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.
What to do
Dealers will replace the oil strainer and perform an oil change free of charge.
Owner notification letters are expected to be mailed on May 20, 2022.
Owners may contact Audi customer service at (800) 253-2834. Audi's number for this recall is 21H7.
