Additional Notes

  • The transfer case fluid capacity across all four configurations of the Mercedes-Benz E-Class Coupé / Cabriolet C238/A238 falls within a range of 0.65-0.68 liter. A specified range rather than a single fixed value reflects normal manufacturing tolerances in the transfer case housing, meaning the correct fill level is confirmed by the drain-back method or a level check port rather than a precise measured volume alone.
  • The E 350d 4MATIC Coupé / Cabriolet 238.334/434, produced for the 2017-2018 model years, carries a transfer case fluid change interval of 77,500 miles under normal use conditions.
  • The E 400 4MATIC Coupé / Cabriolet 238.366/466, also covering 2017-2018, shares the identical 0.65-0.68 liter capacity and 77,500-mile normal-use change interval as the diesel-engined E 350d variant, despite being a different powertrain configuration.
  • The E 450 4MATIC Coupé / Cabriolet 238.368/468, introduced for 2018-2023, continues the same 0.65-0.68 liter capacity and 77,500-mile normal-use service interval established by the earlier 4MATIC configurations.
  • The E 53 AMG Coupé / Cabriolet 4MATIC+ 238.361/461 carries a notably shorter transfer case fluid change interval of 46,500 miles or 36 months under normal use conditions, compared to the 77,500-mile interval specified for the non-AMG 4MATIC variants. The addition of a time-based limit of 36 months means whichever threshold is reached first governs the service point.
  • The 4MATIC+ system used in the E 53 AMG differs mechanically from the 4MATIC units in the other configurations, and the reduced 46,500-mile interval on the AMG variant reflects the more performance-oriented demands placed on the transfer case fluid in that application.
  • Across all four configurations spanning 2017-2023, the transfer case fluid capacity specification remains unchanged at 0.65-0.68 liter, indicating a consistent transfer case unit is used throughout the C238/A238 lineup regardless of engine or trim designation.
