Hydraulic drive (all models except "station wagon" and front-wheel drive with a gasoline engine up to 9/89, issue.)
Clutch pedal height and play should be checked when engaging and disengaging is difficult and after removing the clutch switch. The clutch switch is located on the pedal box and informs the injection control unit when the clutch pedal is actuated. On a diesel engine, a thrust bolt is screwed in instead of a switch.
Check/Adjust Pedal Height
1. Measure the distance from the top of the pedal to the mat. Required value: Models since 10/89: 196 - 204 mm; diesel models, as well as all-wheel drive up to 9/89, 229 -234 mm.
2. If necessary to remove the lower facing of the panel of devices to get to the adjusting screw. Disconnect the plug from the clutch switch -B-, loosen the lock nut -A- and adjust the pedal height by turning the switch. Tighten locknut firmly 15 Nm.
3. After this adjustment, the pedal play should be checked.
Check/Adjust Clutch Pedal Play
1. Press the clutch pedal with your finger until you feel a noticeable resistance. Measure pedal play. Required value: from 5 to 13 mm. Note: When pressed, a slight resistance should be felt after 0.7-3.3 mm. This is the point where the push rod touches the master cylinder piston.
2. If required, loosen locknut -C- and adjust pedal play by turning piston rod -D-.
3. Fully depress the pedal and measure the distance remaining from the pedal to the mat. Required value: Models since 9/89: 41 mm minimum; diesel models, as well as all-wheel drive models up to 9/89 MY: 82 mm minimum.
4. Tighten locknut -C- firmly 15 Nm.
5. After adjusting the pedal play, check the pedal height again.
6. Connect the plug to the clutch switch and install the instrument panel trim.
