Audi 8

[Alitis007]

Id get someone with a scanner to see what the car has to say first, really not the sort of car id want to be poking around just guessing with.

Definitely get it scanned first, euro cars are smart, too smart actually coz they even log a fault code when you change a light globe. I had a quick read of that link and the fault of that car was that the fan was working flat out while the car was working. But like they said you could have a fan computer fault or if the audi's are like the bmw's and have an electric waterpump for the heater that can cause all sorts of dramas. It'll be VERY VERY expensive to guess and replace parts so go get it scanned, even if you go to the dealer and pay for an electronic diagnostic report which may cost 100+$ to be certain.
