Volkswagen Group of America, Inc. (Audi) is recalling certain 1998 Audi A8 and 1997-1998 Audi A4 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 inflator may absorb moisture, causing the inflator to explode or the air bag cushion to underinflate.

Consequence: The inflator could explode during air bag deployment, resulting in metal fragments striking the driver or other occupants. An underinflated air bag may not properly protect the occupant. These scenarios increase the risk of serious injury or death.

Remedy: Dealers will replace the driver's air bag inflator with an alternative inflator of a different design, free of charge. Owner notification letters were sent September 21, 2021. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 69BT. The vehicles in this recall were mistakenly omitted from recall 20V-056. All vehicle owners have already been notified by mail and informed that the remedy is available.
