As you have an x-drive model, the transfer case uses a special BMW fluid. When it is changed, there is a reset procedure for the transfer case control unit. A service computer is required to do that reset. 60,000 miles is a pretty good interval for this compartment as well.

Yes, there are lots of threads here about changing these fluids. A search will show them. Search on the full site, not just the E70 forum.

Gonna resurrect this thread...it being Easter...ok that was bad.

Anyways, I have looked in the TIS and do not see where the transfer case unit has to be reset when changing the oil, only when the transfer case is being replaced. Any references?

Thanks
