Hello Porscheaner, I brought the following question here from the A1 GB forum, because I received almost no feedback there (is probably very technical but less administratively knowledgeable): we wanted to allow our 2020 A1 35 TFSI DSG CityCarver in Germany (the car has been running on a French diplomatic license plate since 11/2020). The registration service informed me that this was not possible because “the emission class expired”. From the point of view of the registration service, the It is a formality that can be fulfilled by the dealer by way of an exception. Unfortunately, Audi itself is completely covered (I only received a process number) and the dealer is not responsible or unable to do so. So is there currently without support. Who can tell me what this emission certificate is about? What basis does it allow to bypass an expired emission class by way of an exception? Thank you for your knowledge transfer, cheers.
