NHTSA lists 3 safety recalls and 17 owner complaints for the 2001 Audi Allroad. Most complaints involve fuel/propulsion system (3) and equipment (3). The EPA rates it 16 mpg combined.
VOLKSWAGEN IS RECALLING 68,240 MY 2001-2004 AUDI A6 QUATTRO VEHICLES EQUIPPED WITH 2.7L, 2.8L, OR 3.0L ENGINES AND MY 2001-2005 ALLROAD QUATTRO VEHICLES EQUIPPED WITH 2.7L OR 4.2L ENGINES. THE AGING OF THE PLASTIC MATERIAL IN THE FUEL TANK ROLLOVER VALVE COMBINED WITH BENDING STRESS FROM THE ALUMINUM VENTILATION LINE TO THE ROLLOVER VALVE NIPPLE MAY LEAD TO CRACKING OF THE NIPPLE. IF THIS HAPPENS, A FUEL LEAK MAY RESULT.
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.
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.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“FUEL AND FUEL VAPOR LEAKS FROM THE TOP OF THE FUEL TANK PRESENTING A SERIOUS FIRE HAZARD WHEN MOVING (SLOWLY OR AT HIGHWAY SPEEDS) OR STATIONARY. THE FUEL LEAK IS MOST OBVIOUS WHEN THE TANK IS MORE THAN 1/2 FULL. VAPOR EMISSIONS OCCUR AT ALL TIMES RESULTING IN A FAILURE TO MEET EMISSIONS STANDARDS. A HARD PLASTIC MATERIAL IS USED FOR THE FUEL TANK'S VENT. IT IS CONNECTED TO A RIGID ALUMINUM VENT LINE. RELATIVE MOVEMENT AND AGING HAS RESULTED IN A FAILURE OF THE PLASTIC VENT. AUDI'S RECALL FIX FROM 2008 (NHTSA 08V-157) - I.E., INSTALLING AN EPOXY-FILLED MOLD - HAS NOT PREVENTED FAILURE OF THE PLASTIC VENT. SINCE THE PLASTIC VENT IS 'WELDED' TO THE TOP OF THE HDPE TANK, THE ENTIRE TANK MUST BE REPLACED TO ADDRESS THE FAILED VENT.”
“I HAVE REPLACED BOTH CATALYTIC CONVERTERS ON THE 2001 AUDI ALLROAD. THE RIGHT ONE AT 42K MILES AND THE LEFT ONE AT 62K MILES. THE RIGHT CATALYTIC CONVERTER HAS FAILED AGAIN AT 115K. THE DEALER REFUSES TO EXTEND ANY WARRANTY FOR THE PART. THE DEALER STATES THAT THE ORIGINAL PART IS WARRANTED FOR 80K MILES, BUT THE REPLACEMENT PART ONLY FOR 12K MILES OR 12 MONTHS. THERE MUST BE SOMETHING WRONG WITH THE CAR OR THE EQUIPMENT. AUDI SHOULD WARRANTY A REQUIRED FEDERAL EMISSIONS PART MUCH LONGER THAN JUST 12 MONTHS. *TR”
“DT:THE VEHICLE HAS DEVELOPED A CAM SHAFT GASKET LEAK AT ONLY 60,000 MILES. ALSO, ONE OF THE CV AXLES CRACKED. THERE WHERE NO PROBLEMS WITH THE VEHICLE PRIOR TO THE DEALERSHIP FINDING THESE PROBLEMS. THE DEALERSHIP DESCRIBED TO THE CONTACT THAT THIS PROBLEM WITH THE CAM SHAFT GASKET COULD CAUSE A MAJOR OIL LEAK. IF THIS WERE TO OCCUR THE ENGINE COULD SEIZE BECAUSE OF LOSS OF OIL. THE VEHICLE HAS NOT CURRENTLY BEEN REPAIRED BECAUSE OF THE COST.*AK”
