easy job..........4 screws on the top of the grille, 2 screws in the wheel arches on each side which secure the arch trim to the bumper, 2 screws (on each side) underneath which hold the lower part of the wheel arch liner to the bumper, 2 screws where the under tray goes on, take off a square plastic cover from up inside the wheel arches, pull the arch liner out from behind the bumper and there are 2 10mm bolts (1 on each side) which secure the bumper to the wing and 3 or 4 (cant remember!) plastic trim clips under the number plate, give it a yank and it'll come off
