2000 Audi s4 has strong smell of gasoline

first of course is to look for leaks second, get the emissions and recirculation canister and related stuff looked at..be careful here because this could ultimately explode in the garage..park it outide if nessecary...and dont overfill the cars' tank,, too many people do this and get fuel inside all the overflow tubes..not a good thing.. fill until the hose turns off once and stop....good luck...

leak goimg to the engine bay area or cracked fuel tank.

Check under the hood on the side of the fuel rail, the fuel pressure regulator value, this is a common problem.

not sure on the auto version if this is one ,doesnt it just pop off like the manual one i would have thought so

2000 GMC Jimmy is smelling strongly of gasoline Google Search

fuse holder burnt out

Don't know this car but from the age, I'd start looking for damaged fuel or vapor recovery hoses

I purchased a 93 Villager in 1999 and it developed a gasoline smell inside. The problem was the fuel filler hose / pipe that was covered by a manufacturer's recall. It was repaired by the Mercury dealer at no cost to me. You should contact the local Mercury dealer. This year Villager also had a problem with the crankshaft breaking, although they never had a recall for that problem, the crankshaft diameter was increased for the 94 and newer models.

do u have a check engine light on? do u overfill the tank? which is to say when the filler nozzle clicks off do u still try to put more fuel in? in any event u most likely have a overloaded carbon canister, pull the canister out and check it for gasoline saturation, the carbon canister is located under the car in a tray near the fuel tank.

Change your fuel filter
