Help Pulsating Clutch

[MadBaz]

Next door neighbour has a 04 1.8tdci estate and today the clutch has been juddering, this happens in all gears including neutral and at any speed, the problem is intermitttent and last from a few seconds to several minutes, there is no difficulty changing gear or taking up drive.

 

I'm thinking flywheel possibly or possibly servo.

 

Any suggestions are most welcome
