IF FOUND AND NO CUSTOMER COMPLAINT, NO ACTION IS TO BE TAKEN. IF FOUND AND ONLY IF A CUSTOMER COMPLAINS, THEN REPLACE GASKETS AND LEAK TEST THE ENGINE. THIS IS AN UNACCEPTABLE POLICY OF HIDING BY LACK OF DISCLOSURE, THE LEAK AND UNFAIRLY SHIFTING THE COST OF A MANUFACTURING OR DESIGN DEFECT TO THE CUSTOMER. AUDI NEEDS TO BE HELD ACCOUNTABLE AND FORCED TO COVER THESE LEAKS FOR AN EXTENDED PERIOD OF TIME AND NOTIFY OWNERS TO BRING THEIR CARS IN FOR INSPECTION AND REPAIR. *JB

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.
