ive a 2000 petrol boxer and the speedo has stopped recording the miles. I watched as it clicked over to 40000 and the next time I looked it showed 04000! The speedo and tripmeter are working normally. I'm worrying if I go to sell it'll look as if I've clocked it. As well as that I'm getting a red injector light coming on when I start it but then it goes out after a second or two with no apparent effect on the running. Anyone else had this?
