Hello,last week they installed a Sachs clutch including LWFW,when I drove home I somethimes couldn't engage the clutch completely,only 3/4 and the pedal stopped,shifting however was never a problem.
Today they changed the actuator ,new slave cylinder and also the pump on the clutch pedal,but it's still the same,all the hydrolics are changed but somethimes I can only push the pedal 3/4,shifting is never a problem also with the pedal engaged 3/4 of full lenght.
The strange thing is when the car is running at idle I can engage the clutch always,it never gets stuck at 3/4.
Nothing is making a strange noise and the mechanic looked at the clutch with a small camera and everything seemes fine.
Anybody have an idea what this strange thing could cause?
Thanks a lot...

 

Any ideas are welcome....

 

my guess woulda been the slave, I think there is a not on it that can get loose and cause problems like you are descriving, very weird...let us know what happened!
