well, I bought the clocks just after I bought the car, because the car still had petrol gti clocks in it so no rev counter or gp light. The guy I bought em off got them from ebay for a project he never finished ( Simon at Brickwerks) so they clocks could have always been faulty, as they never worked right in my car.
Ive found some more clocks from a bloke on another forum, so they should be here any day now, and ive pulled the relay/ relay plug and wiring from a scrap gti for the low coolant circuit ( it is separate from the rest of the fuse box on petrol GTis)
so lets hope with a completley rewired system and new clocks I will eradicate the problem!!!
