There's a
how to over on one of the golf forums (it's basically the same).
But you need the stalk , loom and extra loom. The extra loom just extends the basic loom to go into the ecu(it's not as scary as it sounds)
It envolves removing steering wheel and scuttle panel, then feeding one wire into the fuse box and the rest into the junction box under the scuttle , then extending that into the ecu.
All that you have to do then is get it enabled via vag-com and I'tll save you around £90
