I always removed the headlight.
On a FL model, remove grill, remove screw holding the trim under headlight (sometimes this screw is a plastic clip), then the 3 hex screws holding the headlight, plus all the electrical connectors. Granted, bottom screw is a slight faff, but doable.
On PFL/MFL, if it has headlight washers, you have to loosen the bumper to get the headlight washer past the bumper.
This, but I have no idea what grill requires removing...
Yeah, realized that, as FL just opening bonnet was enough, but cannot get the headlight off, more tips needed:
Removed those three hex bolts and the plastic clip fixing the trim in headlight (radiator side) and removed all the bulps and connectors.
I can move the light one centimeter to front and one centimeter to the radiator direction but cannot ge it out. Do I have to remove the trim under the lamp or bend it somehow? If trim have to be totally removed how it is locked in the wing side, please help. I cannot see down there (too big head).
