I bought an excellence 2.0 Dsg which was never supposed to have one, and fitted one successfully. Note they changed slightly when the SatNav screen got bigger and a couple of the buttons swapped over, so look for a wheel that is either new or from a very recent crash at the breakers. Once this is in you need to code the steering wheel electronics to look for the paddles. I don't recall having to do anything else. Anyone with vcds or obd11 should be able to do this with ease. Unlike some other features it didn't (as far as MY2018 for certain) require SwAP codes which only the dealer can source.
