Noise and vibration in the clutch pedal

Moin moin, in advance the mandatory information about my vehicle: Volvo V50 Engine: 2.0D BJ: 2006 KM: 190.000 Since my last ride I can observe the following: I have no gear inside and do not kick the clutch pedal: everything is fine. If I start to press the pedal a little bit I hear a noise after a few mm clutch pedal path as if something rubs together (not loud, but already perceptible). I push it further through it goes away, but I get light vibrations in the pedal. W I have virbations and also a changed noise, that I can not really describe.The gears switch cleanly through and when I drive on the highway comfortably in the 6th gear in front of me, then everything is as always. No increased consumption, no exiting gears, no smell, no whistling, no nothing. I mention the last things, since I have of course already tried google and motor talk myself. Spontaneously I would have been on stage. klager and/or ZMS typed, but since I am layman and the symptoms somehow only partly fit the parts I addressed, I wanted to ask here. I was not in the workshop yet, but will be done this week. Thanks already for your trouble and your time.
