Known issues on the 2001 A8 Quattro. Two recalls are on federal record for this model year. The first covers the automatic transmission: the shift-lock cable can move out of position over time, allowing the shifter to be moved out of Park even without the ignition key in the lock, which lets the vehicle roll and crash without warning. The second covers the fuel tank filler pipe and cap: the blind cover at the filler neck may not seal properly, letting fuel vapor escape and reducing fuel tank pressure enough to trigger the leak detection system and an instrument panel warning light. Owners have filed 18 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing a shift-lock cable fault to inspecting the fuel filler seal or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2001 A8 Quattro.
