Lowering – Registration from old vehicle letter

Hello people, the following problem: I own a deeper Audi 80 convertible. Now I have to make TÜV, but the TÜV criticizes the non-existent registration of the lowering. Actually ok, but when I bought the vehicle from the previous owner, was in the vehicle letter, which the old vehicle letter was devalued and withdrawn. In this ALTEN vehicle letter everything, including the lowering, was entered. Of this he gave me a copy. Now to my question: Do I have the Eintra or is it somehow possible to transfer the text (registration) from the old vehicle registration for a certain fee on the car office??? Thank you
