After noticing my clutch was slipping I decided to change it on my 2002 2.2DTI (Y22DTH) Diesel Omega. After I changed the clutch I went to bleed it and after bleeding it. The pedal only goes down halfway and stops. It feels like theres pressure once it comes to a halfway point and will not engage in any gears at all when running. I have changed the concentric slave cylinder and still hasnt done any good. Im fed up at this stage and have no idea what the problem is. Can anyone help or has anyone had this experience before. Very desperate help is needed.  :-\ :-\

Clutch plate was pictured when taken out and has "FS" (FlywheelSide) marked on it. Double checked it so its not in wrong way .

Clutch Cover ? You mean Pressure Plate ?

Re bleed the system, ensuring it doesn't drop low on fluid.

This suggests that you refitted the old friction plate :-\

As mentioned..I would be looking at the pressure plate...make sure the fingers in the centre are all nice and even  when fitted,if not query it with your supplier,,if ok then  re- bleed the system  :y

Get someone to press the clutch pedal down while you man the bleed nipple. On cracking off the bleed nipple the pedal should go to the floor.  While the pedal is on the floor do up the bleed nipple and lift the pedal if necessary and repeat.

If that doesn't help things, clamp the flexible hose to prevent fluid flow to the slave. the pedal should firm up if the master cylinder is ok.

Thinking it through...

If the pedal only goes halfway down that isn't a hydraulic problem, but suggests that something is blocking the movement of either the slave cylinder or the pressure plate thereby keeping the clutch engaged :-\

If it were a bleeding issue, then the pedal would drop to the floor with little or no resistance, and stay there...

master cyl has come to the end of its travel before it produces enough pressure,
only answer is to a shorten the adjusting rod, if that dosent work then  change the mc,

Did the new pressure plate have compression clips fitted (that need to be removed once the assembly is bolted to the flywheel) per chance? :-\

Interesting thread. If gears cannot be changed while in motion clutch is not disengaging. Can you engage and disengage gears with car stationary?
If pedal only goes down half way it means that it is pushing against something immoveable, not in need of bleeding.
I suspect Al is right, friction plate is round the wrong way. When I change mine in January, it was clear the friction plate was asymetric. I used a LUK kit, frition plate was labelled 'Getriebeseite', which Al told me meant gearbox side, so that is how I installed it. It worked.
How was your new friction plate labelled? What make kit was it?
