Mercedes-Benz C-Class, W204 (USA / CAN)

Additional Notes

• The Mercedes-Benz C-Class W204 (USA/CAN) transfer case fluid specifications cover 4MATIC variants only, as all-wheel-drive models are the sole configurations requiring a transfer box fill.
• The C 230 4MATIC (204.085) carries a transfer box fluid capacity of 0.6 liter, which is the smallest figure across all W204 4MATIC variants listed and reflects the service fill volume for normal use conditions.
• The C 280 4MATIC (204.081) and C 350 4MATIC (204.087) both specify a 0.7 liter transfer box capacity, placing them in a higher fill volume bracket than the C 230 despite sharing the same normal use condition designation.
• The 0.1 liter difference between the C 230 4MATIC at 0.6 liter and the remaining 4MATIC variants at 0.7 liter indicates a physically distinct transfer box unit in the C 230, as fluid capacity is directly tied to internal volume.
• The C 350 4MATIC appears under two separate engine codes: 204.087 covering 2007-2011 and 204.088/257/388 covering 2011-2014. Both share an identical 0.7 liter transfer box capacity under normal use conditions, meaning the mid-cycle engine code revision did not alter the transfer box fluid fill requirement.
• All four configurations carry a normal use condition designation, meaning the listed capacities apply to standard operating environments rather than severe-duty or first-change-only scenarios.
• A transfer box capacity in the 0.6-0.7 liter range is characteristic of a compact, single-speed transfer unit typical of passenger car-based all-wheel-drive systems, where the transfer box distributes torque between axles without the larger fluid volumes associated with truck-type two-speed transfer cases.
