Remove the real light units. Remove the plastic screws hidden by the light units. Remove the top screw on each mud flap. Unprise the rear boot trim and any hideen screws. Undo the three screws under the bumper on L shape brackets. The bumper now will be just held on by internal clips at each side, so prize the front part of the bumper over the mud flap and body wheel arch and it will slide backwards and off. Place sheets down so not to scratch the bumper as it will be all lose and floppy once its off. Note if you have reversing sensors you must very very carfully disconnet each sensor without breaking any wires.
