BMW 5 Series suffering intermittent fault - how can I fix it?
My 11 year old BMW 525 has done 166,000 miles and is regularly serviced, but has now developed an intermittent fault which prevents the car firing up. It seems to have been a waste of time to replace the starter motor - as the problem persists -it seems to be an electrical issue of some sort. Can you suggest where we might start looking for the problem ?

Flywheel sensor, camshaft sensor, or ignition igniters (coil packs).
