Audi Workshop Service and Repair Manuals

The idling speed stabilisation is integrated in the throttle valve control part. The throttle valve potentiometer, idling speed switch, throttle valve positioner and potentiometer for throttle valve positioner are located inside the housing opposite the cable pulley. The housing must not be opened. All settings are carried out as part of the basic setting with V.A.G 1551. When de-energised the throttle valve moves into a particular, mechanically set position. The throttle valve positioner is responsible for damping the action of the throttle valve as it closes.
