To get to the Reversing Module take the side trim off in the boot - have to take the boot ledge plastic trim off first - so spare wheel out, two bolts in the spare wheel well. Remove luggage hooks if fitted, two screws each. Rubber boot seal on left side - pull that back. Carpet side module is held in then with sprung clips on side and maybe some twist on plastic caps at back of boot. There is also a metal lug on the back shelf which needs to be bent over slightly.
Fella, you posted up the picture showing where the parking sensor module is in my post about my problem with my sensors dont suppose you have a write up or description on what parts of the trim I have to remove to get to the bleeder do you?
