Affected Vehicles



Condition



Vehicle does not start or only starts when pressing the clutch pedal very firmly.



Technical Background



In most cases the replacement of the clutch slave cylinder or master cylinder does not fix the complaint.



Production Solution



Not applicable.



Service



Check the clutch hydraulics and electrics as follows:



1. Depress the clutch pedal to the perceived end stop.



On the clutch master cylinder a second mechanic opens the bleeder screw.



2. If the clutch pedal can now be moved further and the vehicle can be started, or the message "Press clutch pedal to start vehicle" in the cluster goes



out, the sender of the clutch mechanism is correct.



3. Close the bleeder screw on the clutch master cylinder.



The complaint is in the clutch mechanism (wear, check according to repair manual). Do not replace the master cylinder or the slave cylinder for this



condition.
