I had the clutch changed over 3 years ago using genuine L/R parts by someone on this group, and it's never been right - not fully disengaging making gear changing flakey. Vehicle's only done a few thousand since then and now is getting worse. Local independant reckons that it may be the dual mass flywheel - he's having it in next week to investigate but I'd value comments from the kind folk on this group. One option he is suggesting is to replace the flywheel with a standard one - again I'd welcome comments.
