clutch problem

My 2001 325i developed a problem lately after a new clutch was replaced 10 months ago. The car jerks just before I release fully the clutch. Sometime the car shakes a lot and sometimes a little and other times is normal. If I give more rpms before I release the clutch shakes less. Is the clutch disk slipping or is something else? Anew clutch can do that? Thanks for any good ideas.

Was the flywheel replaced along with the clutch, or is the old one still in there ? BMWs come from the factory with a "DMF" (Dual Mass Flywheel), which occasionaly go bad.

The flywheel is the original. After I release the clutch the car do not shake at all. Only the moment before full release of the clutch, the car is shaking. Then, I accelerate fast and it has no problem.

Another possibility is a hydraulic problem....try bleeding the clutch slave cylinder.

Finally the problem was solved guys. It was the mid grade gas. I use a high quality gas and so far the clutch works like new. Thanks for your replies.
