More than 68,000 all-wheel-drive MY 2001-2004 Audi A6 Quattro vehicles equipped with 2.7L, 2.8L, or 3.0L engines and MY 2001-2005 Audi Allroad Quattro vehicles equipped with 2.7L or 4.2L engines are being recalled due to a fault in the gas tank. In particular, the aging of the plastic material in the fuel tank rollover valve combined with bending stress from the aluminium ventilation line to the rollover valve nipple may lead to cracking of the nipple leading to a fuel leak. The recall is expected to begin on or before May 30, 2008 with Audi dealers either reinforcing the nipple on the rollover valve or repairing the cracking at the nipple.
