2001 golf foul smell
Answer
Make shure the interior cabin filter (under the battery cover thing under the hood) is clean. Otherwise make shure that there is no mildew in the passanger compartment. The ac would just blow in mosture if it's drains were pluged
I have a number of Rabbits (pre Golf years) Biggest problem with them was moisture getting inside the car. Passed on to the Jetta(and no doublt the Golf)
Check under the carpets, the underlay is gonna be wet. Very wet. And so to the carpets. That is the smell.
I doubt the airconditioner because that would be too easy.
More likely an older problem...windshield grommet or elsewhere the water is getting in. Pull the underlay and dry it with pistol hairdryer or other as well as the carpet. Smell disappears when dry, then find leak. (A chapter by itself) then put underlay back under.
