BMW 4 series, F32 / F82 (EU)

Brake fluid capacity & service interval

BMW 4 series, F32 / F82 (EU) requires brake fluid with a capacity range between min and max. Service intervals include 24 months and 36 months. The data covers 6 configurations.

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

Additional Notes

  • Across all three 425d power variants covered by the specifications, the brake fluid fill level is defined as between the minimum and maximum reservoir marks rather than by a fixed volume, which is consistent with a top-up or service fill procedure rather than a full system overhaul measurement.
  • The BMW 4 Series F32/F82 (EU) 425d in its 160 kW state of tune covers the 2014-2016 period, while the 155 kW variant spans 2016-2018 and the 165 kW variant covers 2016-2017, meaning three distinct power outputs of the same engine designation carry separate specification entries.
  • Under normal use conditions, all three 425d variants share a 24-month brake fluid change interval, applying to the hydraulic brake/clutch system with DSC.
  • A first change only condition is listed alongside the normal use condition for each 425d variant, and under that condition the change interval extends to 36 months rather than the standard 24 months.
  • The 36-month first change interval across all three 425d variants reflects a longer initial service window, after which subsequent changes revert to the 24-month normal use schedule.
  • The hydraulic system covered by the specifications integrates both the brake and clutch functions alongside the Dynamic Stability Control (DSC) system, meaning a single fluid reservoir serves multiple control functions in these configurations.
