TÜV 2 months extend / delay!?

Hello I have an important question: I was at the TÜV this month and failed! I decided to request the scrapping premium and finally to take a new car. Was already at the dealer and the new car is ordered. BUT, it takes 8 weeks until the new car is there. TÜV expires at the end of February. How can I bridge the two months? If I just cover the TÜV, the insurance protection is going to be fluted to me? n 15 Euro or? Or, can I go back to a different TÜV on February 28th, because again fail and then have four weeks to fix the car again. Or can I DEFINITIV not drive any more when the badge has expired with February. If someone knows about it, would be very grateful about Tips. Thanks in advance, greeting, Michael
