A4'S HAVE A POORLY DESIGNED CAM TENSIONER THAT EVENTUALLY LEAKS OIL. THE COST TO REPAIR THE ITEM IS APPROXIMATELY $1000. THE DEALER (CAROUSEL AUDI) EVEN ADMITS TO THE FACT THAT IT IS A POOR DESIGN AND THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT IT AT THE DEALER. I'VE ALSO READ NUMEROUS COMPLAINTS ABOUT IT ON AUDI FORUMS. THE LEAK TYPICALLY FOUND SHORTLY AFTER THE WARRANTY PERIOD HAS EXPIRED. I FEEL STRONGLY THAT THIS SHOULD BE A RECALL ON ALL RESPECTIVE CARS TO HAVE IT REPAIRED! *NM

21V470000 · Air Bags:frontal:driver Side:inflator Module

Jun 23, 2021

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2000-2001 Audi TT Coupe, TT Roadster, 2000-2002 A4, and S4 vehicles equipped with Non-Azide Driver Air Bag Inflators (NADI) that do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, possibly causing the air bag to deploy improperly in the event of a crash.

Consequence & remedy

Consequence: In the event of a crash necessitating air bag deployment, the air bag may not properly protect the occupant, increasing the risk of serious injury or death.

Remedy: Dealers will replace the driver frontal airbag inflator with an alternative inflator, free of charge. Owner notification letters were mailed November 2, 2021. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69CJ.
