That is correct. The installation of the interface box on the e83 kit will disable the PDC if the system senses a load on the pins only. Will not help if you have a bike hitch installed. That's when you use the dash mounted defeat switch.
Now on the f25 you need to recode a module if you install a hitch with PDC....I seem to remember reading the system recodes automatically with the new module but I could be wrong...
I personally haven't seen a bulletin on PDC reset for the e83.
