This is an Audi 1996 A6 2.6 SE auto. Has been faultless since I bought it when it was one year old. Then tonight when I get in it at Clacton in Essex and start up there is a grinding wirring sort of noise coming from the engine or gearbox when it is in park or neutral but the noise goes away when in drive or reverse. I manage to drive it home no noise in drive, gearbox and engine working perfect, but there are no headlights, indicators, air con, or wipers. Have to drive home giving hand sigs and using headlamp flasher as headlights. (upset quite a few people I can tell you). When I got home I tuned it off and then restated it again. Electrics are all working again, but the noise is still there at standstill in park or neutral.
Anybody know of this problem
Regards David.
