Additional Notes

  • The BMW 2 Series G42/G87 automatic transmission fluid capacity across petrol variants — the 218i PF, 220i PF, 230i PF, M240i PF, and M240i xDrive PF — is uniformly specified at 8.8 liters under normal use conditions.
  • The 220d Mild-Hybrid (140 kW) carries a capacity range of 8.5–8.8 liters rather than a fixed value. A range specification of this kind typically reflects variation between a service refill quantity and a full overhaul or dry-fill quantity, where the lower figure applies when residual fluid remains in the torque converter or valve body.
  • All six configurations share a normal use condition designation, meaning the listed capacities apply to standard operating environments rather than severe-duty cycles such as frequent towing, extreme temperatures, or high-load driving.
  • The 220i PF is the earliest petrol variant in the dataset, with a starting year of 2021, while the 218i PF, 230i PF, and M240i PF all carry a starting year of 2022, reflecting a staggered rollout across the G42 lineup.
  • The M240i xDrive PF shares the same 8.8-liter transmission fluid capacity as the rear-wheel-drive M240i PF despite the addition of the xDrive all-wheel-drive system, indicating the automatic transmission unit itself retains the same fluid volume specification regardless of drivetrain configuration.
  • The 220d Mild-Hybrid (140 kW) is the sole diesel variant among the listed configurations. Its mild-hybrid designation refers to a 48-volt belt-integrated starter-generator system, which does not alter the automatic transmission fluid capacity relative to a conventional drivetrain but does distinguish the powertrain architecture from the petrol entries.
