Had the EPC light come on, on my vRS from a cold start a few weeks ago. Message on dash said fault in stop start system. Car felt and sounded as though it was running on 3 cylinders. Switched off and back on and light went out and car ran OK. Rang garage and booked it in. Diagnostic supposedly reveals an injector at fault, but they have no stock nor the time to do it while its there. Injector ordered and car booked in. Injector fitted and car picked up. Car left for two hours and on restart E
