my dash display counted down from 1000 miles, and it says service in ____ miles and so on, it now just says service, after i went through all the miles. i looked in my book and it said that at 40000 you need to have the haldex clutch filter changed, but i'm at 42,000 even. so i dont know what this service light is about. i drive a 225 BHP 2001 audi TT coupe, with quattro. if you know what this is or what its about. i'd love to hear it.
