Hi. My daughters boyfriends 2002 Cooper S has developed an intermittent starting problem. Sometimes, when he turns the key, all the lights on the dash come on as normal, but then it won't start.
By "won't start," I mean, nothing happens. No turning of the engine, no clicking of relays or dimming of lights. After many repeated attempts, it eventually starts as though nothing was amiss. You can turn it on and off again repeatedly and it will start every time..or not, what ever it feels like at the time. Then it might go days with no probs and then it does it all again.
BMW say they have not heard of anything specific to this problem and would need the car in to diagnose the fault. However, how do you diagnose an intermittent fault? BMW charges £90/hour ish and you could spend £200 just to pay someone to turn the key for an hour or two.
You can usually tell it's going to start on the next turn of the key when you hear a faint click under the steering column from a box tucked up against the front drivers side wheel arch. The box has EWS3-Steuergerat printed on it. We haven't a clue what that box does, but have taken it out and looked at the cct board inside. All looks normal.
ANY clues or help appreciated.
By the way, the car has approx 40k on the clock and full BMW service history but is now out of warranty.
