Additional Notes

  • The Mercedes-Benz CL-Class C215 rear differential fluid capacity splits into two distinct values across the lineup: 1.6 liters and 1.9 liters, reflecting differences in the differential units fitted to various engine and chassis configurations.
  • The CL 500 (215.375, 1999-2006) and the early CL 600 (215.378, 1999-2002) share the smaller 1.6-liter rear differential capacity, indicating both models used a comparable differential assembly during their respective production spans.
  • The later CL 600 (215.376, 2002-2006) carries a 1.9-liter rear differential capacity, which is 0.3 liters greater than the earlier 215.378 variant covering 1999-2002, marking a clear specification change between the two CL 600 chassis codes.
  • The CL 55 AMG Kompressor (215.374, 2002-2006) uses a 1.9-liter rear differential capacity under normal use conditions, aligning with the higher-capacity figure shared by the later CL 600 and CL 65 AMG variants.
  • The CL 65 AMG (215.379, 2004-2005) also specifies a 1.9-liter rear differential capacity under normal use conditions, consistent with the larger differential unit found across the higher-output C215 configurations.
  • All five configurations list normal use conditions, meaning the stated capacities apply to standard operating environments rather than severe-duty or first-change scenarios.
  • A 1.9-liter differential fill volume is notably larger than typical passenger car rear differentials, which commonly fall in the 0.8-to-1.4-liter range, suggesting the C215 AMG and late CL 600 units house a more substantial differential assembly suited to higher torque outputs.
