HI there you can not adjust the clutch pedal operatio n due to the fact they are now hydraulic if the pedal is sticking to the floor more than likely it is the clutch pedal master cylinder, if the cylinder is ok then its possable that the slave cylinder in the gearbox is leaking slightly,or you have a fluid leak on the clutch hydraulic system, hope this helps.
