W212 front parking sensor issue

[ForgxxxR]

Hi folks, some fantastic luck today when a small piece of hardened muck fell off a lorry in front of me and managed to knock one of my front parking sensors through the bumper. What is the easiest way to access these to try and push it back through from behind? Thanks

You'll need to drop the front undertray and if you're lucky, you can get at it from there...that said, Merc bumpers have multiple layers of impact absorbing material behind them (if my 204 was typical) which hampers access and you may end up having to remove the whole bumper.
