Removing Headlights (Bumper)
Some have stated that it is possible to change the headlights without dropping the bumper slightly...attempt this if you like however I would recommend following the below -
1. Remove 3 philips holding the arch lining in the edge. Removing these will not remove the arch lining but will allow access to further holding points.
2. Remove first torx securing bumper to body
3. Remove further 1 or 2 torx (Some appear to have one, mine has 2). To get to these, the arch lining has to be pulled back and held back whilst they are loosened.
Once removed, the bumper will hang like this:
Hard part done, providing none of the screws are rounded/rusted
4. Remove 4 torx under the bonnet.
