    You need a VCDS cable. The coding is this:

    central electronics

    coding

    help with long coding

    Btye 9 to Dec = 0 - as the final brake light
    Byte 10 to Dec = 0 - Fog lamps as a taillight
    Byte 12 to Dec = 36 - dimming rear standlight
    Byte 19 Bit 2 Cold Diagnosis rear active - this must be activated

    Thread revival. I did this and yes my LEDs are working fine, and the fogs are working. But reverse lights are not working. Any reason why this would happen? Cheers

    Hmmm... they should work if they are properly coded. and the ones on the boot lid do not require adapters.
    Have you connected the extra wire on the boot lid lights?
