Additional Notes

  • The BMW 4 Series Convertible F33/F83 differential fluid specifications cover both front and rear differential positions, reflecting the range of drivetrain configurations available across the model lineup.
  • The 440i Convertible xDrive front differential carries a capacity of 0.6 liter, a relatively small volume consistent with the compact housing typical of front differential units in all-wheel-drive systems.
  • The M4 Convertible rear differential with differential lock holds a capacity of 1 liter across the 2014-2015, 2015-2019, and 2019-2020 model year groupings, indicating a consistent fill volume for that assembly throughout the production span covered by these specifications.
  • A change interval of 50,000 miles is specified for the M4 Convertible rear differential with differential lock under normal use conditions, applying uniformly across all three of the M4 year groupings listed.
  • The 1-liter rear differential capacity on the M4 Convertible is notably higher than the 0.6-liter front differential capacity on the 440i xDrive, a difference that reflects the larger physical size and load-bearing role of a rear differential equipped with a locking mechanism.
  • The M4 Convertible year groupings overlap at 2015 and 2019, with separate rows covering 2014-2015, 2015-2019, and 2019-2020, yet the capacity and change interval remain identical at 1 liter and 50,000 miles across all three entries under normal use.
