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.
Dealers will reinforce the nipple on the rollover valve to prevent leakage or repair the cracking at the nipple. The recall began on June 27, 2008. Owners may contact Audi at 1-800-822-2834.
