2004 Audi A6 recalls
Fuel system, other: storage, tank assembly
NHTSA campaign 11V267000 · reported May 3, 2011 · VOLKSWAGEN OF AMERICA, INC · 5,992 vehicles potentially affected
- The problem
- 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.
- The risk
- A fuel leak in the presence of an ignition source could lead to a vehicle fire.
- The fix
- 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.

Electrical system
NHTSA campaign 06V198000 · reported June 5, 2006 · VOLKSWAGEN OF AMERICA, INC · 70,512 vehicles potentially affected
- The problem
- 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.
- The risk
- This condition could lead to overheating or fire.
- The fix
- Dealers will reroute the wiring harness by installing a jumper wiring harness. The recall began on december 16, 2006. Owners may contact audi at 1-800-822-2834.
