I had a 2006 X3, now haw a 09 X5d. I think that all of the adjustments on the list that the dealer can do are actually in the X5 iDrive menu for you to set on your own. For example, the DRLs, the ability to adjust th elock to lock when you put car in D vs at 15 mph, and the ability to select which doors open when you push the unlock button.....
