Known issues on the 2002 A6 Quattro. Four recalls are on federal record for this model year. Two cover 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 cover the headlight switch wiring: connector pins in the switch can short-circuit and cause overheating or fire, and separately, contact from a driver's knees against the knee bolster can push into the headlight switch harness and create an electrical short capable of starting a fire 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 a fuel tank rollover valve inspection to tracing a short in the headlight switch harness, it keeps you on the OEM procedure and the correct specification for your specific 2002 A6 Quattro.
