The biting point on my clutch is very high and the clutch seems to be slipping at times. Is there anyway to adjust the clutch or do i need to replace it?
If i need to replace it can anyone tell me where i can get the parts cheaper?

replace it, parts cheap from a motor factors,
welcome to here

not adjustable, they are hydraulic.

you could get it bled, which may help, replace brake fluid at same time, it should be done every 3years, but most people don't bother, then complain when their brakes fail and they crash

mk2's are terrible for clutchs, been known to go thru 3, yes 3 clutchs in 42k miles
