Defect Description

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.

Safety 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.
