LOTS of washer fluid.
The roads are salted in Skandinavia and that creates a nasty, sticky gunk on the windshield that needs constant washing. I have finished a washer tank in 1 hours driving (cars constantly in front on me).
Other than that, just make sure your tires are good and all fluids are able to handle freezing conditions. I wouldn't worry too much about webasto heating, oil pan heat etc...unless you're leaving the cars parked for more than 48 hours. My 4.8is handled -30 for 4 days (parked outdoor) without issues.
The people up north are very helpful also should you need assistance.
Good luck and enjoy your trip!

BMW does cold weather testing so there is at least some consideration in the design. I would want my battery to be fairly new and at least have the ratings of the BMW specs. I would make sure the CCV system is in good working order. I would have a great set of jumper cables. I would carry two tow straps. I would have warning lights to put out to move over traffic if there is a problem on the road. I would be sure ABS and traction control is working. My primary focus would on proper tires and options to further improve traction, especially with the 4.6, you have that covered.
