Obviously you are in Europe, and as a US ID.4 owner I envy you your ID.3. And idk if the software situation is different in Europe. BUT: for ID.4 in the US, if you have software 2.3 then you have to go to the dealer to update software. After the patch the software can update OTA.
From 2.3 you'll need to head to the dealer - the step up on 2.3 to 3.0 may also require some hardware changes/updates (a heavy duty 12v battery and possibly a controller or two, I've heard). 3.2 update might be done at the same time, and that looks at replacing modules in the main battery.
