This reply is about a month after yours, so you may have done the maintenance by now.
If not, I would definitely do the coolant change since the pH drops over time and could lead to internal corrosion.
I do a drain/fill of the transmission, x-fer case or differential fluid every 60k miles. This is too long for some, and definitely longer than the 'old-school maintenance schedule', but acceptable to me since all fluids are high-quality synthetics.
One last one to consider is a brake fluid since it is hygroscopic and could also contribute to seal wear.
My 05 X3, by the way, now has 162,000 miles and is still a joy to drive.
