The indicator in the dash works like expected, left - activated, right - deactivated, but not the flap itself.

Has there been probably any other firmware update since July 2016 (this was the last version I found mentioned in the forum) which can solve the issue?

We have made changes to the in dash part but the flapper commands should be unchanged. It's possible for 2019 440i they have changed the exhaust command for DRF cars, since there is no car local here, it's difficult to determine. But I'll see if any other DRF customers report a similar issue.
