Total damage – wants to keep FZ – no residual deduction ?

Hello ! After an unincurred total damage with my motorcycle, the expert determined a replacement value of 4.500,00 € with a residual value of 600,00 €. As assumed, the opposing insurance now tries to get out a higher residual value by means of the residual value exchange, clearly accident motorcycles are gladly bought overpriced. Since I want to keep the machine and repair and I do not like to let the insurance ver****** I did a little research and am According to the BGH (VI ZR 393/02), the following judgment was given: Principle: In order to compensate for the damage caused by an accident, the injured person can demand the repair costs estimated by the expert up to the level of the replacement value without deduction of the residual value if he actually has the vehicle repaired and continues to use it. In any case, the quality of the repair does not matter as long as the estimated repair costs do not affect the Wied does not exceed the purchase value. Has one of you been able to enforce yourself with the insurance ? Greeting matteffm
