Probleme beim ACC Nachrüsten im E38 750iL

[V8-GT]

is there really 'sensor' meant for CruiseControl

..or just the backlash on the additional cable, the one that activates the additional traction control flap on the intake body ?!
workshop book tells that the cable for the traction control flap needs to be tight, no backlash .. and every time you turn ignition on and look into the intake in front of the normal throttle flap, you can see that the computer activates the flap and verifies that stepper motor position and additional flap position does match
