In September 2009, I purchased a used BMW 320D M Sport Coupe (12 months old, ex-demonstrator plus one owner, 6,000 miles) from a main dealer. In the 12,000 miles since, it has had 3 replacement clutches, the first two with flywheels, because of clutch judder, particularly when moving off on an incline.

I am experiencing the same problem yet again, but am almost embarrassed to go back to the dealers as they say I hold the record for the number of replacements. I have had BMWs for over 20 years, but this one gives me the least pleasure in driving, Incidentally, I drive two other manual cars owned by myself and my wife, and have no problems, nor have I had problems with clutches in the past. Is this problem unusual?
