Unuse – from when to when? – Unsubscribe?

Hello, I’m pretty much on the hose right now because I hear a lot of different opinions. I hope here can finally give me a reasonable answer to that. I’ve driven in behind an unbraked one, the result: economic total damage, ready to drive but not traffic safe according to report. My main question is, from when to when does a usage loss compensation apply and is it bound to certain things like the registration? People tell me, I should snow my car so ll unsubscribe as possible, because only the time between registration of the accident car and registration of the new vehicle is valid. I also read the time from accident to receipt of the report + time to obtain the new vehicle. I received the report only after 2-3 weeks, why I don’t know. There it says that I need 14 days to get back. The car is still registered. Reason: long wait for reports, and without money of the insurance I can not get a new one, d I wait until I finally have my compensation and then sell the old one and get a new one. What now? Should I now log it off and fetch a new one and apply with the documents for the failure? What is wrong with the time before? Don’t get me wrong, I don’t want to get out of there as many days as possible, the 14 days are enough for me completely. Do I already have entitlement to this or should I actually unsubscribe after 2-3 weeks after the accident and then it only applies to the e time until I have a new vehicle? Would it be very clear and correct from paperwork, but actually total bullshit that I have not got a car for 1 month and then can only start to get a new one and only this time counts.. Hope you can give me a little clarity. As I said, I do not want to apply for several days of usage failure, the 14 days from the report would be optimal. At least a small compensation. Mfg
