Citroen new C4 Grand Picasso clutch lever makes noises

Hello (new) C4 co-owner, I have a new C4 Grand Picasso with circuit. Unfortunately, the clutch pedal creaks and scrapes after a certain driving time. These sounds seem to come from the plastic cylinders on the clutch pedal. The car has 5000km down to now. I tried to solve the problem through a Citroenwerkstatt. They said that this would occur with all new C4, is due to design and is not to be parked. Does anyone have a tip to help? Greet Micah
