Slave cylinder
If the fault code occurs when renewing the ECA or clutch, check that the ECA is fitted correctly. Reset all clutch adaptation in SDP3.Check the ECA fluid level.Renew the ECA.
What you'll see
No driver-visible symptom recorded.
System reaction
The piston stroke of the ECA is not large enough to release the clutch. As a result, it is not possible to drive the vehicle any further.If the piston stroke deteriorates, fault code 50Â 160 for incorrect slave cylinder movement is generated.
Diagnostic depth
Short piston stroke of the slave cylinder.The slave cylinder movement is shorter than expected but adequate to disengage.The OPC control unit has discovered a difference between the ECA slave cylinder and master cylinder position.
There is an oil leakage or air in the ECA.This may be because the clutch or ECA has been renewed and the clutch adaptation has not been reset.
