Additional Notes

  • The rear differential fluid capacity across all listed Mercedes-Benz CLA-Class C117/X117 configurations is 0.74 liter, which is a relatively small volume consistent with a compact rear differential unit rather than a larger axle assembly requiring a full overhaul fill.
  • The CLA 250 4MATIC, covering chassis codes 117.346, 117.351, 117.949, and 117.951 for 2013-2018, carries the 0.74 liter rear differential capacity under normal use conditions, though no change interval is listed in the specifications for that configuration.
  • The CLA 45 AMG 4MATIC carries a stated change interval of 10,000 miles or 12 months under normal use conditions, whichever comes first, applying to both the 117.352 variant from 2013-2015 and the expanded 117.352/952 variant from 2015-2018.
  • The 10,000-mile or 12-month interval on the CLA 45 AMG 4MATIC rear differential reflects a time-based threshold alongside a mileage threshold, meaning the fluid is due for replacement when either limit is reached, not only when mileage accumulates.
  • The rear differential capacity of 0.74 liter remains consistent across the 2013-2015 and 2015-2018 CLA 45 AMG 4MATIC specifications, indicating no change in the differential unit's fluid volume requirement between those two chassis code groupings despite the addition of the 117.952 code in the later range.
