Passenger vehicles equipped with a fuel and vapor leak detection system. A "blind cover" at the filler neck of the fuel tank may not seal properly allowing fuel vapor to escape.

Should this happen, the fuel tank pressure will be reduced, which will activate the leak detection system and alert the driver of a system's fault indicated by an instrument panel light.

Dealers will replace the fuel filler neck/expansion tank assembly. Owner notification is expected to begin during January 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Audi at 1-866-892-2834.
