Hello all! My wife has a 2016 Cooper - today she had an error message come up say ' Clutch overheating, but undamaged' Stop and check etc. After 10 mins message gone so she drove just half mile. Gears became notchy and couldnt get 4th. Parked up. Now, the clutch feels fine and so does the gearbox while stood still, but on clutch release absolutely nothing happens. All gears can be selected while stood still without depressing clutch !!
Background - this car had a new clutch and dual mass flywheel around 5k ago so actually still under warranty with Mr Clutch!! Car serviced regularly etc.

Please help!!

thanks
Mal.
