Problems With Clutch on 200tdi

i cant engage the clutch when the engine is running,but it will engage when its off.the clutch pedal still feels solid.please help.

Hmm i can do a little research on this, but i know that they are hydraulic clutches on the 200tdi, maybe its a cylinder problem???
Leave it with me and i will have think...
