So i am guessing the ACTUATOR has gone bad. I will be pulling it this weekend to take a look just wondering if it will be the same setup or is it more like an e60?? Will any transfer case fluid, be lost when pulled?? if so whats the fluid type or a compatible fluid (d4atf redline)... might as well drain and refill...
Not sure if it will be the same as the X3 or not. From what others posted, no transfer case fluid involved.

BTW, if you do change fluid, you have to buy it from BMW. Expensive - around $50 per liter.
