I have a 2002 Audi S6 Avant and the check engine light comes

Customer Question

I have a 2002 Audi S6 Avant and the check engine light comes on all the time. As per my mechanic, the code is "P0442 - EVAP minor leak detected. (and) Purge valve and gas gap have been replaced. Smoke check has not revealed any leaks." We are stumped. What else can it be?
