Undo the 3 screws in the bottom front edge, and the 2 on the wheel arch side, and then carefully ease it out from the foglight side first.
Its difficult to see, but on the rear of the cover at the top, there is a few barbs moulded onto the cover that snap into the plastic frame behind. You need to release these by sliding a flat bladed screwdriver under the light and over the barb.
Just take your time and dont force anything.
