Jack it up a little, undo the screws on the splash guard under the radiator. On the right hand side undo the 2 screws and release the securing clips from the arch liner under the wheelarch then do the left. With the splash guards removed you should see the bumper mounting bolts, undo them. Remove the upper grille section (the bit around the lights by undoing all the screws and gently pulling if off but dont break the clips, you could edge it off with a flat blade screw driver). Now remove the visable upper bumper screws. Pull the bumper away from the car, make sure the foglights are disconnected.
