Remove the inner light cluster trim on the outside of the boot shut area to reveal two light cluster fixings, remove the two fixings along with one inside the boot to remove each light cluster. This will reveal one bumper fixing either side to remove.
- Remove nine fixings along the bumper lower edge and four from each wheel arch. Carefully remove the bumper from the vehicle body starting at the tips carefully releasing each clip then pull rearward.
- Remove the plastic trim fitted to the rear impact beam, this will be refitted later using its original fixings.
- Remove the exhaust bracket from the rear impact beam, support the exhaust to prevent damage.
- Remove the rear impact but retain fixings. (This is not refitted with the Towbar assembly).
- Cut the under tray to the pre marked area, some models you may be able to snap the pre-cut part to remove.
