THE PROBLEM FORTUNATELY HAPPENED WHILE THE CAR WAS IDLING. THERE WAS A FAULT TO ONE OF THE CYLINDERS, SO THE CAR WAS RUNNING ON ONLY THREE CYLINDERS. ALTHOUGH THERE WERE NO INJURIES, THE DEALER STATED THAT IF THIS WOULD HAVE HAPPENED WHILE DRIVING. THE CAR WOULD HAVE SHUT OFF WITHOUT BRAKES OR ANY OTHER ELECTRICALLY OPERATED SYSTEMS. AT HIGHWAY SPEEDS THIS WOULD HAVE BEEN CATASTROPHIC. THE DEALER ALSO STATED THAT THIS PROBLEM HAS OCCURED ON MANY OF THE 1.8 LITER TURBO A4'S. DT

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.
