Last month i sold my 1.9cdti sri to my mate, he mentioned yesterday that the battery light came on, he said every time he stopped and then restarted the car, the light went off, but if he hit a bump it came back on. Today he was driving down the road and the car cut out, now it wont start and the ignition lights wont come on, the screen for the sat nav aparently 'goes mad', any ideas? its keyless entry and start if that help! thanks guys...
