Official recalls
121V470000 · 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.
