Pursuant to outstanding recall repair: Fuel tank leaks substantially when filled over 1/2 tank. Zimbrick Audi of Madison, WI confirms symptom, and confirms that fuel tank needs to be replaced pursuant to faulty rollover valve nipple. Audi of America is not currently offering a resolution as they claim replacement fuel tank is no longer available. The car has been unavailable to me for over a week. There is no resolution in sight.
VOLKSWAGEN IS RECALLING CERTAIN MODEL YEAR 2001-2004 AUDI A6, MODEL YEAR 2002-2003 S6 AND MODEL YEAR 2003 RS6 VEHICLES EQUIPPED WITH 4.2L ENGINES AND MANUFACTURED FROM JUNE 19, 2001, THROUGH JUNE 8, 2004. 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.
Consequence & remedy
Consequence: A FUEL LEAK IN THE PRESENCE OF AN IGNITION SOURCE COULD LEAD TO A VEHICLE FIRE.
Remedy: DEALERS WILL REINFORCE THE NIPPLE ON THE ROLLOVER VALVE TO PREVENT LEAKAGE OR REPAIR THE CRACKING AT THE NIPPLE. THE RECALL IS EXPECTED TO BEGIN DURING JUNE 2011. OWNERS MAY CONTACT AUDI AT 1-800-822-2834.
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.
Consequence & remedy
Consequence: A FIRE COULD ORIGINATE IN THE LEFT DASHBOARD AREA.
Remedy: DEALERS WILL INSTALL A PROTECTIVE COVERING ON THE KNEE BOLSTER (CRASH ELEMENT). IN ADDITION, THE WIRING HARNESS AS WELL AS THE FELT PROTECTOR ON THE LEFT SIDE OF THE DASHBOARD CARRIER WILL BE CHECKED, AND REPLACED IF NECESSARY. THE RECALL BEGAN ON JULY 26, 2004. OWNERS SHOULD CONTACT AUDI AT 1-800-822-2834.
