Stopped of at the local convenience store yesterday afternoon on the way home from a gig and on getting back in the car the orange engine warning light came on, checked the oil level all OK and car was running fine. Drove three miles to a meeting at my church after dinner, a couple of hours later light still on. It is scheduled for a service at Olly's on Monday. Today start the car and light has gone out, drive to Bournemouth and back with no apparent problems, warning light still out. Weird!
