Now BMW could come up with altered files, where they may add values of gongs and PDC back to stereo settings but they have not.

There is a reason and that is, when you code to hi-fi your rears are low level full channels after coding, comapred to hi-passed pre-coding.
Now considering that, you cannot revert settings of gongs and PDC back to stereo (as that is for high pass setup).

This sounds good in theory but in practical no body know.

I wonder if any of you tried manually changing your PDC and gong settings back to stereo and re-writting MAN into you car?

I guess I have to give it a go.

I have tried to mix and match files.
On few cars 2007 and onward I have managed to successfully mix and match the files and volume of PDC gongs has gone up.
However on 2005-2006, I could not manage to do it due to different modules in those cars.
