This was a fairly simple retrofit, with the biggest part required being the replacement rear bumper. I took the opportunity to upgrade to a facelift rear bumper and diffuser, which came with sensors and sensor loom. This was on my 2007 V6 TT.
Note: this guide covers fitting an early module (part numbers ending 283, the later ones 475). Early modules are on address 76 and use the convenience CAN, compared to 10 and the powertrain CAN for the later ones. I believe the changeover was in late 2008, so before the facelift happened.

Wiring
Since the bumper came with the sensor loom, I didn't have to make that up and I could simply plug it in the new module. The easiest way to tap into the convenience CAN is into the central convenience control module, which is also convenient in its location just under the parking module.
The permanent live feed is taken from the boot fusebox. The drivers sill trim pulls firmly upwards and is only clipped in. The rear seat bench should also be pulled up and removed along with the drivers side boot trim (requiring the rear boot trim, parcel shelf, boot floor and boot foam). This should give plenty of access to run the wires.
I wrapped all my wires in cloth tape and cable tied them to prevent rattles.
