Same problem here and it gets worse when the weather is colder. Clutch pedal sticks down and brake pedal doesn't return 100%. You don't always notice the brake pedal sticking but "hill holder not available", "VDC inoperative" or, when dark, the high level brake light on are the give away.
It is not the carpet and I have had a new master cylinder fitted by AHM and lubricated both pedals. None of this has cured it and the clutch pedal needs lifting the last 1" to 1.5" with your foot.
Now, I have noticed that taking the lid off the fluid reservoir does give a temporary cure so I am thinking the master cylinder may be pressurising. Is there an air bleed system on the filler cap and can it get blocked?
