Easiest way to do it is, slowly but firmly pull up on the gaiter, should just pop out. The hardest bit for me was getting the gear knob off the gear stick, dont know if mine was just stiff or what, but i had to give it a massive pull, finally came off. Then (if DSG) undo the circuit board for the gear lights.
Once full out, simply just pop the silver part off, best to turn it up side down and do it. went pretty smooth, all in all took about 1h 30min including removal from car.
Well worth it though as my plate was scratched and a new one would have cost about £150+ - so nice easy mod.
I chose the black colour - got 3000m x 0.75m - had plenty and a bit spare.
