I have a 2016 C Class Coupe. The front number plate holder has dented where someone has reversed into the front of my car so I need to replace it. I’ve taken the plate off, removed the screws in the plate holder, but it still won’t remove. I’ve unclipped the parts at the bottom that clip into the bottom grille, but it still won’t remove. I’ve had a look and it seems as though there are additional plugs going into the bumper. Is this a case of just pulling them out with force, or is there a certain way to remove them?
