Default Help with a starting issue please

Need some M3 expert forum advice on a starting issue

Been doing a few bits on my car and got all the advice and help from you great people on here and I need your help again !!!

Thought I would take the car out for a drive this afternoon and the remote unlock wouldn’t work on the key, strange I thought so went and got the spare key and that was the same !! I unlocked the can manually and put the key in the ignition but the car wouldn’t start. I mean nothing not even turn over ! All the lights on the dash were on and the battery is fine as it was still on trickle change when I tried to start the car.

A little searching on the net and and see a post where it said turn the key round as if to start the car and hold it round for two minutes !!!! So I did that and surprised it started fine !! I turned it off and then on again and it started ok.

So my question is : why would it not start and why would it start with the key turned round and hold for two minutes ? Does that give it a sudden surge of power or something ???

Strange one that I hope someone can shed some light on

Many thanks.
