Can i ask: My S3 - 02 plate (70k), has started playing up with clutch. The pedal, only when cold(worst first thing in morning) goes half way down before there is bite. This will last 1-3 miles or upto 5 minutes, generally untill warm. Then the pedal is back at the top. Having no problem selecting gears and the clutch itself does not seem to be slipping. I am lossing no fluid and have found no leaks. Should i be looking at master cylinder or is there something else i should look at first? Thanks for any advice.
