There might be a problem for later cars due to interconnectivity with Stuttgart.

I don't know how far that goes, but I heard somewhere that later ones, everything is interconnected to the backend .

Like, want to replace the PCM head unit
Dealer can't do it, Stuttgart has to like punch in the new serial and link it to the VIN of the car.

Some others may comment on that, I never delved deeper into it, I've not gone beyond the 9x7 era, and those are still based on pretty straighforward local coding..

Note, that's for coding new or replacement parts.. I would expect error clearing to still be possible...but these cars, many models and modules clear codes on the individual module via Canbus, not ODB2..
