Hello with each other, have the following problem. I bought a B4 2.0 66KW (EZ 12.92, Re-Import from Denmark, type key number is only 000000) to save taxes I have installed a minicat from Walker but the Dekra examiner does not want to enter it. He thinks it would be a Us-Kat in and that does not work. Can this be that there are B4`s without G-Kat? Is such a problem known when registering ? Does someone know a solution because the 304 € normal tax are really bad ?
