I have a 2001 A6 Quattro Avant and when I let the gas filler do an automatic shut off gas spills out and drips down behind the rear wheel. Maybe a cup or so. It is NOT from the overflow tube attached to the rubber flange around the filler neck. I also have a check engine light which codes a 442 I believe. The parts store guy says it indicates a small evap system leak. Is it possible to remove the stuff at the filler neck to see what's leaking? Any suggestions would be appreciated.

I checked the recall and talked to Audi USA and they said that my car is not covered by the recall concerning the evap system. They said that if I take it to the dealer I can pay for the diagnostic and IF it's the same problem as the recalled vehicles they would cover it. $600 gamble in my estimation. Help!

 

remove your rear tire on the fuel fill side and then remove the plastic inner fenderwell you will then be able to see the fillerneck and its related parts there are numerous parts hidden in that area its not just a filler hose and air vent as you find on most vehicles. more than likely one of the hoses or the plastic tank has developed a leak this would explain both of your issues.
