I was looking at retro-fitting a power tailgate as in Oz it is only offered in an options pack with a sunroof and an ugly brown/grey leather trim with a white border :-(

These are the parts required, as best as I could determine:

• 2GA827552A 905 - 1 * RH Strut - Gas Filled
  
  2GA827851B 905 - 1 * LH Strut - Motor Drive
  
  3G0827887C - 1 * Motor to close tailgate latch
  
  3G0854719B - 3 * Motor Clips
  
  2GA827535A - 1 * Bowden cable
  
  2GA827506A - 1 * Lid Lock for power tailgate
  
  2GA827427A - 1 * Strut Mount Bracket - RH
  
  2GA827428A - 1 * Strut Mount Bracket - LH
  
  5Q0919279 - 1 * Buzzer
  
  5Q0959107N - 1 * Tailgate Control Module
  
  N91158501 - 2 * Trim Clip
  
  3G0959831BWHS - 1 * Push Button Switch

plus a wiring loom and coder - https://www.kufatec.com/en/volkswagen/vw-t-roc/t-roc-a11-ac7/cable-set-electric-tailgate-for-vw-t-roc-a11-42748

But it starts getting a little expensive over here, although there are many second hand parts available in Europe that would make it much more attractive.
