Hello! I have a strange behavior of the clutch pedal at my Volvo S80 2.4 from 1999. Kilometer level: 146 000 km. If I am on the road from about 18 degrees on warm days, for example, without pressing the clutch for several minutes, then you can only hit the pedal very hard (at the first-second) times. After two times kicking everything is normal again. The warmer it is outside and the longer I am on the highway the harder the pedal becomes. In winter you have the problem also noticed but clearly less. It is probably the first clutch, because I did not find any papers about a change and otherwise got all invoices from the previous owner. Does anyone have an idea for this problem?
