In this guide we will show you how to adjust the clutch actuator manually.  However, bear in mind that you may still need to get it fine tuned via the Mercedes Star machine.

First thing is to jack the N/S rear of the car up and located the clutch actuator. (circled here)

With a E10 socket slacken the three bolts securing the actuator to the gearbox:

Gently slide the actuator right (into the housing) until you feel resistance, and allow the actuator to push itself back out. (it will move itself out approx 1/2mm)

Finally secure it back in place by re-tightening the E bolts.
