The BMW 5 Series G30/G31/F90 (EU) manual transmission fluid capacity is specified at 1.2 liters across all listed 520d configurations. For a manual gearbox, this figure represents a service fill volume, meaning the amount of fluid required during a routine drain and refill rather than a full overhaul or bench-rebuild procedure.
Both the 120 kW and 140 kW variants of the 520d share an identical 1.2-liter manual transmission fluid capacity. Despite the difference in power output between the two engine tunes, the gearbox fluid volume remains consistent across all listed model year ranges for each variant.
All specifications are designated for normal use conditions. In fluid service contexts, a normal use classification typically applies to standard on-road driving patterns, as opposed to severe use, which would cover conditions such as frequent towing, extreme temperatures, or high-load operation.
The 520d (120 kW) specifications are divided across three consecutive model year ranges: 2017-2018, 2018-2019, and 2019-2023. The same structure applies to the 520d (140 kW) variant, with the 1.2-liter capacity remaining unchanged across all three ranges for both power outputs.
