Additional Notes
- The BMW 6 Series Gran Coupé F06 transfer case carries a dry fill capacity of 0.62 liter across all listed xDrive configurations. A dry fill figure represents the total fluid volume required when filling a completely empty or freshly rebuilt unit, such as after a full overhaul or replacement.
- The service fill capacity is 0.44 liter for every listed configuration, which is the amount used during a routine fluid change where residual fluid remains in the unit after draining. The gap between the 0.62-liter dry fill and the 0.44-liter service fill reflects that retained volume.
- Both the 640i xDrive Gran Coupé and the 650i xDrive Gran Coupé share identical transfer case capacities of 0.62 liter dry and 0.44 liter service fill, indicating no capacity difference between the inline-six and V8 engine variants in the F06 lineup.
- The 640i xDrive Gran Coupé spans two separate specification entries covering 2013-2015 and 2015-2018, while the 650i xDrive Gran Coupé entries cover 2012-2015 and 2015-2018, yet both pairs carry the same capacity values within each model, showing no change in transfer case fluid volume across those year ranges.
- All four rows are designated for normal use conditions, meaning the listed 0.44-liter service fill applies specifically to standard operating environments rather than severe-duty cycles.
