Recently i observered that the clutch on my 2 yr old punto is hardening. I've not found any sort of slipping as yet and the gear changes are smooth but when i took it to TASS he confirmed that it is slowly hardnening (nothing to worry as of now). TASS also told me that due to operational wear and tear it has happened like this. I've done roughly 28000kms. Now my concern is whether i can ask for a replacement under warranty? Or is there anything else i can do to fix the problem?
