The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- Both the X4 xDrive20d and X4 xDrive35i carry an automatic transmission fluid capacity of 8.5 liters, which is a figure typical of a full service fill rather than a partial drain-and-refill procedure.
- The BMW X4 F26 (EU) xDrive20d, covering model years 2014-2018, specifies the 8.5-liter capacity under normal use conditions, meaning the figure applies to standard operating environments rather than severe or demanding duty cycles.
- The X4 xDrive35i, also spanning 2014-2018, shares the identical 8.5-liter normal-use capacity despite pairing a turbocharged petrol inline-six with the transmission rather than the four-cylinder diesel found in the xDrive20d.
- An 8.5-liter automatic transmission fluid capacity is consistent with ZF eight-speed units commonly found in BMW vehicles of this generation, where a complete fluid exchange requires significantly more volume than a simple pan-drop service.
- The normal use condition applied to both configurations indicates the stated 8.5-liter figure is not adjusted for fleet, towing, or other elevated-stress operating profiles within the provided specifications.
