Paint damage/strip damage

Hello dear community! After a long time it happened with us again: someone has striped our Svenson over the left wheel. When my dad arrived today from the work and he saw it immediately to the, because there is there vllt. 800m away. Well, they have looked at this with the result that it must have been a white vehicle. But what makes me stutzig, which he has been rather far up. Vllt. something like that direction Q7/X5? As you can see on the pictures, is on the bumper nox, only over the wheel run he has a bit bigger bump. My question: is there fast need for action because of rust o.Ä. Or can we first take a little time with us? I know, remote diagnosis is always so much a thing, but someone knows advice nevertheless? Greetings, Tim PS: my dad works in the hospital (anäshesist) and on the parking lot (he always sets himself off) then turn at the end. Something like a note was unfortunately not present. Either not minded, not minded, not minded, not minded.
