Accidental victim, despite lawyer I remain on the cost?!

Good morning together, I’m really shocked what’s happening to me…. I’ll give you a brief description of the approach. My car was properly parked and the road was parked. A neighbor drove his tractor and crane trailer backwards into my passat. He reported immediately and well. The VW contract workshop immediately told the lawyer in case of damage in the height. Well I did. 2 days later Rief hit this and I said I can now appoint an expert. llt. 290€ +49€ compensation/day. The lawyer has submitted it to the insurance company but they wanted to have their own expert look over it. After that it was only 1200€ + 43€/day. Of course the 2nd expert had painted positions like varnish. Ok with that I can have car repaired so 4 days in the workshop. Now my lawyer writes he doesn’t understand why the E… Not the 49€/day and my expert wants to count. Now I would have this Guta If I want my money, I have to go to the court. Something is going wrong here! Why should I pay any costs now? I am only the victim here in this matter. I have to report to my lawyer next week. Do you have any advice what I should do now..?? Thank you very much!!!
