Additional Notes
- The BMW 6 Series Coupé F13 (USA) transfer case fluid specifications cover xDrive variants of both the 640i and 650i Coupé, spanning model years from 2011 through 2017.
- A dry fill capacity of 0.62 liter applies across all listed configurations. Dry fill refers to the total fluid volume required when filling a completely drained or newly assembled transfer case unit.
- A service fill capacity of 0.44 liter is specified for all listed configurations. Service fill represents the smaller volume used during a routine fluid change, where residual fluid remains in the unit after draining.
- The difference between the 0.62-liter dry fill and the 0.44-liter service fill amounts to 0.18 liter, which reflects the fluid that typically remains trapped in internal passages and cavities during a standard drain procedure.
- All five configurations carry a normal use condition designation, meaning the stated capacities apply under standard operating conditions rather than a severe or first-change-only scenario.
- The 640i Coupé xDrive appears in two separate specification entries, covering 2013-2015 and 2015-2017, both sharing identical dry and service fill values of 0.62 liter and 0.44 liter respectively.
- The 650i Coupé xDrive is represented across three distinct year-range entries: 2011-2012, 2012-2015, and 2015-2017, all of which carry the same 0.62-liter dry fill and 0.44-liter service fill capacities.
