Air Bag Inflators May Underinflate Bag

NHTSA #20V056000 · Air Bags — Frontal — Driver Side — Inflator Module · NHTSA notice

Reported January 31, 2020 · Volkswagen Group of America, Inc.

Potentially affected: 106,857 vehicles

Repair completion: 2.4% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Manufacturer campaign 69BT · Owners notified September 21, 2021 · Recall influenced by NHTSA's Office of Defects Investigation

Defect description

Volkswagen Group of America, Inc. (VW) is recalling certain 2000-2001 TT Roadster, 2000 TT Coupe, 1999 Audi A8, 1998-2000 Audi A6, and 1999-2000 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 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.

Manufacturer remedy

Dealers will replace the driver frontal air bag inflator with an alternative inflator when the parts become available, free of charge. Owner notifications were mailed September 21, 2021. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69BT.
