5.6% of complaints about the 1998 Audi A6 came in the first year, which is unremarkable for a 1998 vehicle — around the middle of the 180 model-years on record. The median complaint arrives at 5.8 yr in service. The most-reported system is fuel system (19 complaints), typically at 2.3 yr or about 80,500 miles.
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.
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.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH HALOGEN LOW BEAM HEADLIGHTS, CERTAIN CONNECTOR PINS IN THE HEADLIGHT SWITCH CONNECTOR COME INTO CONTACT WITH EACH OTHER CAUSING A SHORT CIRCUIT. NOTE: VEHICLES WITH XENON LOW BEAM HEADLIGHTS ARE NOT AFFECTED BECAUSE THE CIRCUIT IN THESE VEHICLES CONTAINS A FUSE, WHICH PRECLUDES EXCESSIVE CURRENT FLOW IN THE CASE OF A SHORT CIRCUIT. AUDI S6 AND S6 AVANT VEHICLES ARE ALL EQUIPPED WITH XENON LOW BEAM HEADLIGHTS AND, THEREFORE, ARE NOT LONGER AFFECTED BY THIS RECALL.
THIS CONDITION COULD LEAD TO OVERHEATING OR FIRE.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 2.8L, V6 5-VALVE ENGINES, AND AUTOMATIC TRANSMISSIONS, WHILE DRIVING DURING EXTREMELY LOW AMBIENT TEMPERATURES THE THROTTLE MAY FREEZE IN AN OPEN POSITION DUE TO ICE ACCUMULATING IN THE THROTTLE BODY.
IF THIS OCCURS, THE VEHICLE MAY FAIL TO REDUCE SPEED WHEN THE DRIVER LIFTS HIS/HER FOOT FROM THE GAS PEDAL. THIS LOSS OF VEHICLE CONTROL COULD RESULT IN A CRASH WITHOUT WARNING.
ON CERTAIN PASSENGER VEHICLES, IF A DRIVER'S KNEES PUSH AGAINST THE KNEE BOLSTER (CRASH ELEMENT) LOCATED UNDER THE DASHBOARD, IT CAN CONTACT THE HEADLIGHT SWITCH WIRING HARNESS, AND AN ELECTRICAL SHORT COULD OCCUR.
A FIRE COULD ORIGINATE IN THE LEFT DASHBOARD AREA.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SULFUR IN FUEL INTERACTS WITH CERTAIN ADDITIVES FOUND IN WIDELY AVAILABLE GASOLINE CAUSING SULFUR TO BECOME DEPOSITED ON THE CONTACT POINTS OF THREE FUEL SENDING UNITS MOUNTED INSIDE THE FUEL TANK. THIS COULD CAUSE THE FUEL GAUGE TO READ FULL WHILE THE FUEL TANK MAY NOT IN FACT BE FULL OR COULD BE EMPTY.
RUNNING OUT OF FUEL WITHOUT WARNING WHILE THE FUEL GAUGE INDICATES THAT THERE IS SUFFICIENT FUEL IN THE TANK LEAD TO SAFETY PROBLEMS.
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.
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.
THIS CONDITION COULD CAUSE INSUFFICIENT VACUUM TO BE PROVIDED TO THE BRAKE BOOSTER.
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH QUATTRO DRIVE SYSTEM WHICH EMPLOYS A FUEL AND FUEL VAPOR LEAK DETECTION SYSTEM. IF THE VEHICLE IS REFUELED SHORTLY AFTER THE ENGINE IS STARTED, AND IS KEPT RUNNING WHILE BEING REFUELED, THE FUEL VAPOR RECOVERY SYSTEM COULD PRODUCE SUFFICIENT BACK PRESSURE TO CAUSE FUEL TO BE EJECTED AFTER A COMPLETE FILL-UP WHEN THE FUEL PUMP NOZZLE IS REMOVED FROM THE FILLER NECK.
IN THE PRESENCE OF AN IGNITION SOURCE, FUEL SPRAY COULD RESULT IN FIRE OR POSSIBLE PERSONAL INJURY.
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.
SCREEN PIECES COULD ENTER THE INTAKE AIR FLOW SYSTEM AND PREVENT THE THROTTLE PLATE FROM RETURNING TO ITS FULL IDLE POSITION.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. DURING PRE-ASSEMBLY OF THE FUEL TANKS, AN INCORRECT FILLER NECK WAS INSTALLED CAUSING THE FILLER NECK TO NOT "MATCH" THE FUEL CAP.
THIS CONDITION COULD ALLOW FUEL TO ESCAPE AND IF AN IGNITION SOURCE WAS PRESENT, A FIRE COULD OCCUR.
FUEL INJECTION SYSTEM DID NOT DISENGAGE WHEN BRAKES WERE APPLIED, ENGINE CONTINUED TO REV AT 1600 TO 1800 RPM WITH BRAKES FULLY ENGAGED.
VEHICLE WOULD CONTINUE TO ACCELERATE, EVEN AFTER REMOVING FOOT OFF THE ACCELERATOR PEDAL. DEALER AND THE MANUFACTURER WERE NOTIFIED. *AK *TT
VEHICLE SPEED CONTROL: VEHICLE CONTINUED TO ACCELERATE AFTER RELEASING ACCELERATOR AND WHILE DEPRESSING BRAKES. RPM'S REV'D AS HIGH AS 5000.
FUEL INJECTION SYSTEM DID NOT DISENGAGE WHEN BRAKES WERE APPLIED, ENGINE CONTINUED TO REV AT 1600 TO 1800 RPM WITH BRAKES FULLY ENGAGED.
