Great. Gave me the confidence to try! I had to break a lot of the little green cc lips and if you have a air bag there is another hidden screw at the top of the door to release, but all is good now. I just need that spare part to arrive!
Update: all good and working now. By the way the torx screws can be undone using the screwdriver Renault include in the wheel removal toolset in the boot.
