The dealer has no other choice than to flash the latest DATEN files to your car with the dealer software they use. That means you will leave the dealer with the new "rom" version along with the modified tune.
Daten files contain every DME flash available for your car that BMW developed, including the PPK tune. That is how people flash PPK on their own without a code. you can use winkfp, a more powerful program than dealers use, to flash the car with the PPK tune without the code (so long as you know which tune/ZUSB number the PPK is otherwise it just updates you to the latest stock DME software). You also don't have to upgrade every module in your car like the dealer is forced to do when they use their software.

I've 2011 N55, do you know what instructions can I follow to do PPk stage 1 or stage 2 myself?
p.s. I'm not sure what DME version I'm on since I bought it used.
