Known issues on the 2002 A6. Four recalls are on federal record for this model year. Two involve the fuel tank rollover valve: aging plastic combined with bending stress from the aluminum ventilation line can crack the valve nipple, and a resulting fuel leak near an ignition source could lead to a vehicle fire. The other two involve the headlight switch wiring harness: connector pins can short-circuit, or a driver's knee pushing against the knee bolster can contact the harness and cause an electrical short, either of which could lead to overheating or a fire originating in the left dashboard area. Owners have filed 96 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing the headlight switch wiring to inspecting the fuel tank rollover valve or a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2002 A6.
