Bagatal damage or not?

Hello together, now it also caught me (or my E91): In the company’s own underground car park a colleague has striped my car while parking. The result were two smaller, barely visible scratches next to the fog lamp, a longer over (paint at this point) and a about three cm large dent on a nasty edge of the M-stick incl. removed paint. Since I could not first assess to what extent it is a minor damage, which idR applies without expert report I went to the local BMW workshop. This thought that the bump in the plastic would not be pushed out easily and will now provide me with an estimate for a new front apron. Anyone who knows the part prices and labor costs at BMW can imagine that this will certainly be between 1,200 and 1,500 EUR. In principle, my plan would be now, the damage herewith plus loss of use for a day and flat cost for the journey. I am afraid, however, that this would have the possibility of rejecting the KVA as too high (which I could understand in principle, the workshop in turn has an interest in as lucrative orders as possible). If a consultant who has been commissioned by me would then also place the damage in the area of a bagatelle, I would probably be at the expense of it. Apart from a lawyer… I assume that I would not be able to both should still be commissioned by me even after the first assertion? How would you proceed? Thank you
