The software update web address has now changed from BMW.com/update to
https://www.bmw.com/en/footer/software-updates.html which by the way now needs the full 17 digit VIN instead of the previous last 7 digits.
In addition, the previous 9041 bin file is no longer available for my 2018 430i. It now shows the older 9032 bin file as the latest available update file. Looks like they pulled 9041.
