And all this time I thought it was in the cabin...
There's no sound while the clutch is engaged, there's no sound once the clutch is released.
It's purely in the pedal action.

I drove one of Rollguy's 240Ds a couple months ago and couldn't believe how easy his clutch pedal was to depress. Very, very little resistance... reminded me of a euro rental. Mine on the other hand has always been firm, though (subjectively) it feels like it's getting a little stiffer. It's certainly noisier.

I've read a bit in the archives and I have my suspicions, but curious what the clutch gurus think.
