Hi
Im fairly new to this site but thought someone may be able to help me. I have a 150 BHP GTTDI golf (2003), recently my clutch seems to be acting up on occassions. The clutch seems to slip in the higher gears after 4th gear at above 2000 rpm where the revs go up suddenly cos i assume the clutch is slipping and then come back down to normal. This happens when i put my foot down slightly. Also I have when i come off the motorway after about an hours drive the clutch pedal goes really soft with no resistance till the very bottom which makes it very difficult to change gear (biting point goes lower) temporarily for a few mins straight off the motorway after whcih the clutch returns to normal. These problems have got me worried as to what the cause may be? Does this mean i need a new clutch how can i find out? Also how much would it cost for a new clutch parts and labout assuming it is a new clutch i need?
Would really appreciate any help/advice as its driving me up the wall!

Thanks
Rio
