Doesn't the X-drive do an auto adjust every time it's started? I thought I read it here. I can use my FoxWell 520Pro to do a transfer case adaptation. A shop locally changed the filter, oil, and transfer case oil for $125. Saved me a lot of time and mess. I had it done after a transfer case gear upgrade. The gear is polycarbonate. With a drivetrain refresh and maintenance, the X5 launches hard. Plus wider tires, it launches good for a 3.0i from a dead stop. Fresh transmission oil makes a big difference. Shifts are nice and firm.
