Mercedes benz W204 2009 clutch judder when cold start ?!

[Xhemal]

Hi guys ,
As title says i get car vibration after putting in first gear and release the clutch. This happens only in the morning when the car is cold, during the day the clutch works perfectly .
Any idea what could it be ?

Thanks

It could be due to a number of problems, but start with the simple.

It is possible that it is due to moisture forming on the clutch overnight.

If you have a reasonable warm garage park it in the garage overnight and see if it judders in the morning.

Oil mist can also cause a first engagement judder when cold.

Eliminate, or confirm the moisture probability first.

Rear crank seal? Any oil showing at bell housing
Possibly 1st motion shaft seal.

Yes only with the first gear vibration , Reverse and other gears are ok

Maybe small leak n that's shot off by time you use other gears. Eng mountings good. Tho I wud expect judder from them to be thru near all gears at gear change.

I had this on my w115 and couldn't find any signs of a rear crank seal leaking (though that doesn't mean yours isn't leaking) I tried the select 3rd gear with hand brake applied with engine revs high and slip the clutch trick, which helped the clutch shudder in first gear take off for about a week. Finally I removed the gearbox to discover a worn pressure plate.
Once I fitted a new clutch kit all was good.

Fair call. Used to be a known issue on spring pressure plates. Not so much but still poss on diapram pressure plate.
