Note: This problem could cause different warning messages to display or the engine oil warning light to turn on. 

Safety Risk: 
A sudden loss of engine power could increase the risk of a crash. 

Corrective Actions: 
Audi will notify owners by mail and instruct you to take your vehicle to a dealership to replace the oil strainer for the turbocharger oil supply. The dealer will also inspect and document the performance of the boost pressure system and change the engine oil.

The company will notify owners by mail and instruct you to take your vehicle to a dealer to install a retaining plate on the engine compartment seal.
