I have a 1999 A4 with a 1.8 turbo. The car is driven daily and after about 4 weeks its dead and wont start. As the weeks go on it turns over slower till it doesnt start. I replaced the battery and had the altenator check and it was fine. The only thing that seems to stay on are the lighted window switches but im unable to find a fuse for them. Does anyone have a suggestion?
