This is good news for me either way, thanks!
I had this crazy notion that because the servo
looks like a motor that spins around all the way,
when you install it if its too far down for closed valves
or too far up for WOT, the computer would bring it
down or up on its own. I thought that could be a way
to control idle.

That's what I was worried about when installing. You
would think as advanced as the system is it would sort
itself out on its own. There's no idle control valve so WTF!?
Leave it to BMW to keep info glued to themselves to fix.
Good that you can adjust the hex key to get it right
which I figured was possible anyway.

My nominal value is a little off from my actual value with
the eccentric shaft, but I'm idling fine and revving to redline
no problem. So I don't know why that is. Thanks for the
