Girlfriend of the bloke next door, wow she's gorgeous but that's not the point.....has a 318i Coupe. Anyway, it won't start, the starter motor clicks but doesn't turn the flywheel. Tried attaching a booster thingy to the battery once we found it, it's in the boot by the way.
Didn't make any difference but the headlights are dim when tested engine off, so I still suspect the battery. We did, however, manage to bump start it OK .
It's such a long time since a car broke down on me that I've forgotten most of the checks. ( Except the Espace of course but ironically starter / battery problems were one of the few categories of problem it didn't have...wretched thing... )
