You can connect to the module which gives invalid ISO code, disconnect from it and send report (red button) - that way developers should get this ISO and maybe will add with next update.MES still says invalid ECU ISO code. I had hoped that installing version 4.6 would clear that message but such is not the case. Maybe next revision? Since the car is 2018 I thought it was old enough to have the code recognized but I guess not. I don't remember seeing this message before the W05 reprogram but I don't see how that would affect the ISO code so it has to be my memory failing.
There are still plenty not supported ISO codes to be added.
Also after update you can have invalid ISO code on module which was fine before - most likely due to new software loaded. Have seen that myself on couple cars.
