-the insurance should cover the parkschaden (if you have taken up that option), but only above a certain deductible.

-if you know the offender, then it is all covered by the offender's insurance, and you don't have to pay anything.

I have had both experiences. The second one was a lady who was kind enough to leave me a note on my windscreen. Big thanks to her!

So if there is a parkschaden, you should really try to figure out who did it...
