Clutch: Service and Repair

Bleeding clutch operation
The actuating hydraulic system is bled via pumps on the pedal.

Note:
^ On right-hand drive vehicles, the supply tank is located in the area of the brake fluid reservoir/control module for automatic headlight beam adjustment (ALWR)!





1. Fill supply tank.





2. Open bleeder valve on the servo unit -(arrow)-.

Note:
^ Make sure that the reservoir is not sucked dry. Top up during the procedure if necessary!





3. Pump with the clutch pedal until Pentosin emerges without air bubbles at the bleeder valve of the servo unit (use collecting bottle).

Note:
^ If a bleeding device filled with Pentosin is available, clutch bleeding can proceed in the same manner as for previous systems!
^ To do this, the bleeding device is connected to the clutch reservoir at the front!
^ The clutch high-pressure hydraulic system does not need to be bled in a special manner!
^ It is sufficient to actuate the clutch pedal approximately 10 times with the engine running!
^ The steering hydraulic system is bled in the usual manner!

Disposal of Pentosin
Pentosin can be disposed of together with waste oil.
