As title, can anyone give any pointers to removing a standard 6n steel rear valance (the bit below the bumper)?

Remove the plastic upper cover, 4 large torx screws in opening of tailgate, then 3 screws in each wheel arch then pull the plastic cover off then the metal valance can be pulled off

Remove the rear bumper by the screws under the bootlid and in arches, then take the bolts off for the valance and it will drop off :)

I've un done the plastic cover bolts, the four under the tailgate and the ones in the wheel arches but its still firmly attached at the bottom. Any ideas?

Pull the corners of the bumper outwards from the arches, the bumper has a lip on the end so it holds onto the arch, pull it away from the arch then slide off
