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 & remedy
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.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE TIE RODS OF THE STEERING ASSEMBLY ARE PROTECTED ON EACH SIDE BY A SEAL TO PREVENT MOISTURE AND DUST PARTICLES FROM ENTERING THE SWIVEL BEARING MECHANISM. IT IS POSSIBLE THAT SOME TIE ROD SEALS MAY NOT SEAL PROPERLY.
Consequence & remedy
Consequence: IF MOISTURE AND/OR DUST PARTICLES ENTER THE SWIVEL BEARING MECHANISM, THE SWIVEL BEARING COULD WEAR OVER TIME DIMINISHING THE STEERING CONTROL OF THE VEHICLE.
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSIONS. A CONTROL VALVE IN THE VACUUM HOSE CONNECTING THE BRAKE BOOSTER TO THE INTAKE MANIFOLD MAY NOT OPEN OR CLOSE FULLY AT TEMPERATURES BELOW -4 F UNDER CERTAIN DRIVING CONDITIONS.
Consequence & remedy
Consequence: THIS CONDITION COULD CAUSE INSUFFICIENT VACUUM TO BE PROVIDED TO THE BRAKE BOOSTER.
Remedy: DEALERS WILL INSTALL A VACUUM BY-PASS SYSTEM INTO VEHICLES OPERATED IN THESE STATES WHICH IS DESIGNED TO PROVIDE SUFFICIENT VACUUM FOR FULL BRAKE ASSIST UNDER ALL WEATHER CONDITIONS.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. IF THE ENGINE BACKFIRES DURING A COLD-START, AN AIR SCREEN WHICH IS LOOSELY SEATED IN THE AIR FLOW METER CAN BECOME DAMAGED.
Consequence & remedy
Consequence: SCREEN PIECES COULD ENTER THE INTAKE AIR FLOW SYSTEM AND PREVENT THE THROTTLE PLATE FROM RETURNING TO ITS FULL IDLE POSITION.
Remedy: DEALERS WILL INSTALL A RETAINING RING TO HOLD THE AIR SCREEN IN PLACE.
