Additional Notes
- Across the Z4 2.2i, 2.5i, and 3.0i variants covering 2002-2006, the manual transmission fluid capacity is listed as 1 to 1.1 liters, with no distinction made between initial fill and service fill values.
- The BMW Z4 Roadster E85 3.0si (2004-2008) and Z4 M Roadster (2005-2008) both carry separate initial fill and service fill figures, where the initial fill stands at 1.6 liters and the service fill at 1.5 liters.
- An initial fill capacity, such as the 1.6-liter figure on the 3.0si and M Roadster, reflects the total volume required when filling a dry or overhauled transmission, while the service fill of 1.5 liters accounts for residual fluid that remains after a standard drain.
- The 0.1-liter difference between initial fill and service fill on the 3.0si and M Roadster is a relatively small margin, indicating that the transmission retains only a minor amount of fluid during a routine service drain.
- The 3.0si and M Roadster specifications are each split into two separate entries based on the transmission label present, specifically the MTF-LT2 label and the MTF-LT3 label, though both label variants share identical capacity figures of 1.6 liters initial and 1.5 liters service fill.
- MTF-LT2 and MTF-LT3 refer to BMW manual transmission fluid specifications, and the label found on the transmission housing determines which fluid type applies, making label identification a necessary step before servicing the 3.0si or M Roadster gearbox.
- All specifications across the full 2002-2008 range are listed under normal use conditions, meaning no separate capacity or interval figures are given for severe use in any of the configurations covered.
- The earlier 2.2i, 2.5i, and 3.0i engines share a uniform capacity band of 1 to 1.1 liters, whereas the later 3.0si and M Roadster units require noticeably more fluid at 1.5 to 1.6 liters, reflecting a physically larger or differently designed gearbox in the higher-displacement and performance variants.
