Are you sure you have a cvt? Mk2 also came with a robotised 6-speed automatic gearbox from 2008 to 2010. It has a lever with + and - rather than just P, R, N and D.
If I understand this correctly, these are normal 6-speed gearboxes with a conventional clutch but the gear selection and clutch actuation are carried out through an electronic actuator which is bolted to the side of the gearbox. There is a conventional clutch set-up with a release lever and normal clutch hydraulics (master and slave cylinder) but all the "leg work" of pressing and releading the clutch pedal is co-ordinated by the electronics.
As Marco1979 says, It just has a lever with + and - in place of P, R, N and D. My car also has + and - paddles on the steering wheel which also allows up and down changes.
I had a problem with the reversing light and bought a replacement gearbox switch for an auto which, as it turned out, was a different thread size and would not fit.
