There are 2 small screws either side of the fog lamp by accessing from behind the unit and getting under the vehicle. These seemed to release the front part of the unit to presumably access the bulb. The problem is the front only moves a small distance forward before hitting the black plastic insert in the bumber. So I took out the 4 screws holding the plastic plate in place hoping to slide this out of the way and leave a larger hole for the front of the foglight to slide out of, but the plate can't be removed because of the foglamp itself

Can anyone point me in the right direction please.
Cheers
