Clutch slave cylinder for Jetta TDI, Golf TDI and New Beetle TDI on the A4 chassis.
A soft clutch pedal, a pedal that does not return upwards or inability to disengage the engine are common symptoms of a failing slave cylinder. If the clutch must be pumped to shift it also may indicate a leaking slave cylinder
We strongly recommend replacing the o-ring seal that connects the hard hydraulic line to the slave cylinder. Available as a checkable option.
