Function The position of the throttle is controlled by a digital position controller which emits a pulse-width-modulated (PWM) duty cycle and a direction bit. After the output stage has been deactivated, the throttle is brought into emergency air position by means of two springs. This return of the throttle must take place within a certain time. If this time is exceeded, a fault is stored in the memory. Diagnosis conditions Ignition on (approx.30 sec. ) Stationary vehicle Engine not running Engine temperature> 5 °C Intake air temperature> 5 °C 1 Perform adaptation. 1. Switch on the ignition. 2. Wait one minute . Do not press the accelerator. 3. Switch off the ignition for at least 10 seconds. 4. Read out the fault memory

Removing and Installing Generator Removal 1. Disconnect the battery and cover terminal or battery. Undo the fastening screw for the air cleaner housing and the hose clamp on the throttle body. 2. Disconnect the electrical plug connection on the air flow sensor and remove the complete air cleaner assembly. 3. Relieve the drive belt at the tensioning pulley and remove the belt. 4. Disconnect the electrical plug connection on the vacuum switchover valve and unclip the switchover valve from the holder. 5. Undo the holder at the intake distributor (2 screws) and remove. Pay attention to the sealing ring (vacuum line for brake booster) when removing. 6. Undo left fastening screw (in direction of travel) and unscrew. 7. Undo right fastening screw (with deflection roller) by three turns. A gentle tap on the fastening screw loosens the threaded bushing in the generator arm (use aluminium mandrel). Unscrew fastening screw and remove with deflection roller. 8. The generator must be turned clockwise so that the swivel arm is near the crankcase and the holding arm projects beyond the fastening eye. 9. Carefully pull the generator back a little and undo the electrical connections, or press the plug connection to the generator housing, release (arrow A) and pull off. Pull out generator to the rear.
