I think there was a fair backlog of approvals for the new Euro 6D-Temp which came into force for all new registrations from 1 September 2019. The main reason would be the need to comply with the new testing procedure that came in to force following "diesel gate", Small manufacturers would have found themselves at the end of the queue, particularly as they would not have their own testing facilities.
Yes, I think you are spot on
I’ve heard the same, that there is a massive backlog which is causing delays in being able to register new models
