What is the proper RPM for idle on my 545i? Mine is at 700 and seems kind of high.

Not high at all. your computer automatically adjusts for proper idle.

I don't know the proper one, but my 545i shows 700 as well .
I noticed it changes a little with A/C on/off .

It's only at 700 rpm when the compressor is running. It's not on all the time even when the snow icon stays lit.
