Any workshop can command WV screwdrivers, at least in the EU. I think the new regulation is that if you don't have the piece, or the tools necessary to replace the piece, you have to produce the plans on how to do it.

I know someone who had an issue with his old WV Kombi, and thought it would be the last drive (Around 2020-2021). He found an auto shop who could manufacture pieces and replaced every single malfunctioning pieces from plans they got directly from WV.
