Here is a post with a pic that member posted and now I am thinking that the "unknown" was due to him changing the werte value instead of the drop down?
Regardless, and in theory, if you restore all the original CAFD from backup is there likely still some sort of trail (I assume there always is with software, but hoping nothing this obvious or noticeable)?
Yes, I think in that instance, incompatible Werte Values were used.
There may be some way to tell, but again with normal FDL coding nothing is obvious, especially after the coding is removed and the module is returned to the original state. Now if you alter your VO Options, and / or change your Production Date and write it to the car, and do not reverse that, that will easily be discovered. If you flash the firmware on an ECU, which can't be reversed, that may or may not be noticed.
