A search for this problem will show it is very common on R53 S's. On NAM I was surprised to see it still present on the R56. Being still present on the R56 means there is no modification or new design kit available. I have a 04
JCW MCS and have learned to live with this, only does it when cold and especially if it is damp. The facelift 05
MCS's suffer this noise. Common theories are split up between: 1) Glazing of the clutch plate - which is unlikely at low milage 2) movement in the dual mass flywheel - a complicated flywheel is used on Mini, it is not solid, Google for explanation on this on LUK or How Stuff Works or 3) the release/throwout bearing - this however does not give the chewbakka sound. It will not damage the car, it is irritating but there is no guarantee that a new clutch will solve the problem permanently. IMHO - leave it alone.
