I get some kind of noise (almost sounds like it's coming from the middle or rear of the car?) when I let out the clutch of my '07
MCS. Doesn't sound like a "click" to me - more like the sound of something brushing against something else - but it's only at the moment you described (at the point of clutch release).
Don't remember hearing it when moving into the highest gear(s) - and maybe not even when downshifting into lower gears - but definitely hear it often when releasing the clutch to shift up in the lower gears.
Could be the same thing?
