Hello, have found out the following up to now: Yes, but car is registered within 18 months (temporary decommissioning). So if the car was not registered 18 months ago, can I go to Tüv with the stamped license plates?! Should I apply for an insurance number (Huk-online e.g.) first? (double card) I don’t have to use it then?! I just want to do TÜV and not leave it again.
