I have a 13 plate mk3 skoda octavia 

Has 90 thousand on the clock 

The clutch pedal has started to stick half way up 

Only does it periodically 

Have no clutch slipping or loss of fluid 

Please can someone put me in the right direction of what it is 

Oh yeah the on off feature of the engine seems to have stopped working 

Hi Tannerman, my 65 plate (MY16) Octavia has done the same thing on one occasion only, at less that 17,000 miles - as I was moving off from a traffic light, it cleared the next time I operated the clutch. It felt like something had caught the pedal but couldn't see anything that might have done so. I didn't feel any obvious clutch-slip when this happened, but the clutch bite-point at the time felt really odd.

Clutch pedal not fully coming up will almost certainly prevent the switch that restarts the engine after a stop, from operating.

I will monitor your post for possible cause of this.
