TÜV expired, cancellation

Moin, I have a small problem. The TÜV of my motorcycle has expired 4 months. Now it is not worth putting the whole device into a TÜV worthy condition. I have now received a letter that I should pay 25€ and send a TÜV report within 1 week. Can I now push the thing into a garage, go to the registration office, log off and send the registration confirmation to the regulatory office? Would that have been assumed as soon as it is logged out and not t on public ground everything is okay. But the information I find so is partly somewhat contradictory. Greetings
