I was going to ask the same thing, since dealers are now more and more picky, they are always looking for reasons to deny a claim and just slap "external forces" or "owner modification". I doubt that they can spot if iDrive disclaimer is missing, but they can definitely spot some of the other modifications.

I understand that you are only changing active/non-active parameters, but if they are available and BMW did not add them, I wonder if there is a reason for it. Most of these modifications done by coding are not available as an option, so BMW is definitely not trying to charge us to add those features.
