Reminds me of a Kawasaki GPz1100 I bought brand new many years ago when digital fuel injection was new technology.
After a short while it would only run on 3 cylinders and I took it back to be fixed under warranty. It lay untouched in the workshop for days and when I complained to the manager about how long it was taking to be repaired he simply said, "we know nothing about fuel injection and we're not going to learn it in the next 10 minutes".
Buyers of cars with the very latest technology are really just guinnea pigs.
I agree in principle, BUT...
One of the advantages of high-tech EVs is that in essence the diagnostic process can be fully automated and done by computer, and, when manual human intervention is required, it can be done remotely by techs in Germany (or anywhere else in the world).
The idea of a sophisticated piece of technology sitting idle because the local techs don't have the skills and training, points at a complete misunderstanding (or misaplication) of the whole concept of high-tech EVs
