I have fitted a MSFW from an Up!, which fits and the buttons work too, just no light.
Found this guide last night on 1k8 buttons. : https://www.mk5golfgti.co.uk/forum/inde ... 12.45.html
This wheels buttons is 2h0 959 442, and is slighty different to the 1k8, my question is, does anyone know where solder on this part?
