Disbursement – duration of replacement

Hello, my car was rammed, I drove to an expert, he confirmed in his report a total damage. The opposing insurance paid the replacement value and deducted a residual value from it. I gave a copy of the purchase contract of my new car so that I get the VAT paid. So far it seems to me to be conclusive. However, in my report it says: “Replacement duration 14 days, usage loss per day 23 Euro” If this sum is still due to me or What circumstances must be present for this? I am grateful for all the tips Bimmel
