I have a 89 S5 turbo II with a fresh rebuilt engine in it. It idles a little too high after its fully warmed up, around (1100 rpm). I would like to take it down to 800 to 700. I am new to rotary. can someone show me a picture of where the idle adjusting screw is? I have an idea of where it is but not sure exactly which screw and how to adjust it. please advice thanks!

 

This is a S5 T2 motor in a first gen but the adjust screw should be in the same place.

coo thanks steve-ohh, whats the difference of turning that screw compare to turning the screw on the BAC valve?

 

when your car idles does the throttle rest on the screw I showed you?
