PDC sensor

Hello, gentlemen.

Something's going wrong. Yesterday afternoon, I was at the media market to get something (a mistake). Saturday, full booth, parking a problem for themselves (because many of our fellow human beings unfortunately do not manage to place their "big" vessels between the wise lines) and the StVo (despite the signs: "In this parking lot the StVo" applies at the entrance to the parking lot).

Long story short meaning, finally found parking space and pure into the next pleasure. Everything was worried and back to the car and when I was in the trunk I was already looking for someone to drive me against my right bumper.

Unfortunately, there is no name, free according to the motto: "Oha that will be expensive let us run away quickly" or "The Macker has coal enough, he will get away with it"!

Well, the scratches are almost polished away, but the PDC sensor on the corner I unfortunately pushed in resp. He was already on one side.
Now, my real question, how do I get it out? Destroy the bumper base, right? Give me a hint, please.
