Auto trans is due every 60K or 4yrs, along with the internal filter, although the dealers don't push it due to the shear cost involved in doing it through them.

No service interval on the bevel box (mounts to the transmission, sends drive to the rear wheels), but nothing stopping you from giving it an oil change. No special oil required, just an off the shelf 75W90 full-synthetic gear oil.

Haldex coupling (on the front of the rear diff) oil is due every 3 years from MY10-onwards.

No service interval on the diff oil itself, but again as per bevel box, you can do it if you chose to with the same oil.
