Hi to all,

I also have the comfort entering or keyless go. First, avoid to open the car with both keys in range of the sensors, this might "confuse" the silicon brains a bit. The key itsself has no memory at all for this settings, they are in the cars central electric. This electric recognizes the key (no. 1 or 2) when you open the door or press the open button on the key and restores the saved settings. To get all settings changed you have to activate some functions in the iDrive setup menu (that you press the iDrive) und menu point car / wheels (I hope it´s named like that in USa, mines a german one). If you go through the options you may activate or deactivate the seat function and choose if it will change upon you open the drivers door or earlier when the car is unsecured.
The passengers seat won´t change position at all. The key to be used may be somewhere in the car not in the slot, and even there is no memory selected for the seat it will go back to the last seat position used with this key...
By the way, the memory selcet 1 or 2 are for each key. so yo have 4 positions to save...

Sorry for the not matching English, I´m an Bavarian guy trying to do my best.

Enjoy your X5 as I do

So long

Christian
