330Ci E46 Auto - Intermittent starting prob.
Discussion
Happens only about once or twice a month. First happened about a year ago.
Turn the ignition round to start position and it sort of "clicks" but nothing - the starter motor does engage. Lights fully bright throughout and do not dim, so apparently there is no short to ground.
If you push the car a few inches, it will then start normally.
Starter motor was deemed faulty as mechanic had to knock the starter to get the car running.
We only realised the trick with moving it, some time after the new starter motor was fitted.
Most of the time it starts first time on the button, as had previously been the case since new in 2003.
It has only ever failed to start when in the garage at home, not when it driven and parked elsewhere. Maybe just luck!
The garage also holds a BMW X5.
We had thought that central locking/anti theft protection might be interfering between the 2 cars. But having tried various combinations of locking and unlocking each, there seems to be no link.

I presume when you push the car you come out of park and back into neutral or park again? it then starts may be the shift sensor
Yes that is what happens.
And thanks to all you guys suggesting the fault is with the "shift sensor".
At least it is not the flywheel which was the advice I got from "Honest John", or one of his minions!
We will not know until the next time it happens, and we just try moving the shift.
The car has been well behaved for the last 2 weeks.
I will keep you posted.
Thanks again,
