Regular BMWs are not capable of really being 2WD in the snow. Once an open diff gets on snow or ice it will just spin one wheel at a time and lose traction really easily. I believe that an xDrive car can lock the rear diff and center diff which makes sure that 3 wheels can always spin at the very least. I don't think that xDrive can lock the front axle (nor do I think it is really necessary).
