Hi guys, I know that the topic of emission standards was already represented. I have a new problem. I drive an Audi Cabrio 2.3 liters NG I wanted to get a minicat now to save taxes. The data from the manufacturers also all agree. Except the year of construction always from 1992 I thought that the road rolled in 1992. but no with me is in appearance in 1990 but at all share in the vehicle in 1992. What now?Already someone had the case? I once had at nem Camaro that I v on Chevrolet got a write that it is the identical vehicle. Greeting Patrick
