Hello, have a B4 2.0 l with 115 hp, “EURO 2” according to the previous owner, I also insisted on this with my Audi search, because I had an annual invoice of 287 € for my last B3 Bj 86, 1.8 l 113 hp. In my current vehicle license is “no-pollutant E2”. Jetz I got a invoice from the tax office over 303 €!!!!!!!!!!!!!!!!!!!!!!!!! As a small explanation was on the 2nd page: “The designation low-pollutant E2 indicated in the vehicle license corresponds to the exhaust emission standard Euro 1.” or s owhat. How can that be? Do they want to fool me or is that really so? Did I pay between my first Audi and the current BMW 2.0l with 150 hp, EURO 2 and 147, did I ever pay that for the B4 also, because of almost the same engine capacity?? Can it also be that the simply made a mistake? I would call, but I only learned it earlier and on Friday evening the tax office is unfortunately not available!
