Just curious, does everyones' 540i's go to fast idle (1200 rpm) even on a hot start? Mine does and I've owned many cars and that seems a little strange.
Just asking.......

Exactly the same with me.
On the first start up on the day, it will idle at around 1200 and there is a slight shaking of the engine. After a few seconds it will drop to about 800 and the shaking will be gone.
At every start up after that, the rpm will rise to 1200 for a few seconds and then settle down to about 700-800 rpm. No shaking occur then though.
