Additional Notes

  • The brake fluid fill level for all listed 325d GT configurations is specified as between the minimum and maximum reservoir marks, rather than as a fixed volume. A fill-to-marks specification is standard for brake fluid service, where the reservoir level is checked and topped off rather than fully drained and refilled by a set quantity.
  • All three 325d GT configurations share a 24-month change interval under normal use conditions, meaning the fluid is replaced on a time-based schedule regardless of mileage accumulated within that period.
  • The BMW 3 Series Gran Turismo F34 (EU) 325d GT is listed in two distinct power outputs for the 2013-2016 period, at 155 kW and 160 kW respectively, yet both share identical brake fluid specifications including the same fill guidance and the same 24-month change interval.
  • The 325d GT variant covering 2016-2018 carries the same brake fluid specifications as the earlier 155 kW and 160 kW variants from 2013-2016, indicating no change in brake fluid service requirements across the model year transition for the 325d GT nameplate.
  • All listed configurations note that the hydraulic system covered includes both the brake and clutch circuits alongside the DSC (Dynamic Stability Control) system, meaning a single fluid reservoir serves multiple hydraulic functions in these vehicles.
