Question on the crediting of pre-damages for accident!

Hi! Write here on behalf of the friend! His car was broken open about 10 months ago. Disc smashed, access to the car, radio stolen: Any small scratches through the splitters at the door, as well as cockpit. At that time his car insurance paid him the damage, painting costs, as well as cockpit new. After KVA was billed, that means he did not have the damage repaired! Now about 10 months later the same game. e way broken open, the disc hit again. Now new scratches have been added by the splinters, in addition also Macken of the splitters on the leather passenger seat! The reviewer acknowledges the new damage without any reason, however, he did not name the additional scratches on the door. Would my acquaintance be entitled to compensation for the additional scratches?! That he does not get again costs for the complete painting of the door, he already has! yes now new scratches have been added, he has no chance to get the `more damage` reimbursed proportionally?! Greetings, Mfg MICHA
