To remove the bumper, first apply the handbrake firmly, jack up the rear of the vehicle, and support it securely on axle stands. For easier access inside the wheel arch, remove the rear roadwheels. Open the tailgate and take out the rear light units, then undo the two bolts on each side located below the rear light locations. Working under the rear of the vehicle, pull out the centre pins and release the expanding plastic rivets securing the lower edge of the bumper. Next, remove the expanding rivet and carefully pull away the wheel arch trim on each side to release the retaining clips from the ends of the bumper, ensuring not to damage them. Undo the retaining bolt on each side that secures the bumper to the rear wing, then have an assistant support one end of the bumper while unclipping the outer ends from the rear wing panels. Check that nothing is still connected to the bumper, and with the help of an assistant, draw the bumper rearwards and remove it from the vehicle, taking care not to damage the wheel arch trims. Finally, disconnect the rear fog light wiring connector and any applicable parking sensor wiring connectors as the bumper is removed. For refitting, follow the reverse order of the removal process.
