My partners Dooper won't start after an interior light drained the battery overnight. She tried jump starting it unsuccessfully (which might be the cause of the problem) and then charged the battery which seems fine. Engine cranks but won't fire and has the automatic stability control or traction control warning light on. It spins over fine, she called the RAC who proved to be totally useless as he couldn't connect his scanner but a friend later managed to connect his but didn't show anything, probably not the right one. Can anyone point me in the right direction please?
