Hi, just wondered if anyone could give me any tips on removing/refitting the upper and lower plastic trim from the estate tailgate?

Remove the pull handle with a Torx bit, and pull the lower trim off, it’s all just clips. For the top, there are 2 plastic rivers, one on each side, remove those and pull the trim off, it’s all clips from there. Refitting is the reverse of removal but it’s easier for the lower trim to sit on the bumper and close the boot (with the button if powered or have a helper hold it in place) while you line it up and refit.
