Yes you need to reset with GT1. Search transfer case adaptations, a bunch of us did it noticing a difference. Yes, transfer case needs the special magic dealer sauce. You can buy it online much cheaper. You need just a bit less than a quart. So buy 1. But it is special for the x-drive units, like a transmission with clutchpacks and all.

With reset adaptations, difference is slight, so if you absolutely can't get it reset, I don't think it will be the end of the world. Although BMW instructions say you must do it. So up to you.
