Recently my clutch has been strange. B series hydro clutch - which is relatively new (less than 1 year).

When I'm driving the clutch gets progressively firmer as I drive/as the car is warmer. Also along with being firmer there is less and less play when the clutch is fully out. This seems to occur progressively on my daily commute. Overnight the clutch seems to settle back to it's regular firmness.

I have checked clutch fluid and there hasn't been a change. Also no leaks can be found.

Any ideas what may be the issue?
