Additional Notes

  • The rear differential fluid capacity across all listed Mercedes-Benz CLA-Class C118/X118 configurations is 0.6 liter, a figure consistent with a compact rear differential unit rather than a larger axle assembly requiring a full overhaul fill volume.
  • The CLA 250 4MATIC in body codes 118.347 and 118.647 carries a rear differential fluid change interval of 46,500 miles or 36 months under normal use conditions, whichever comes first.
  • The CLA 35 AMG 4MATIC in body codes 118.351 and 118.651 shares the same 0.6-liter rear differential capacity and the same 46,500-mile or 36-month change interval under normal use conditions as the CLA 250 4MATIC.
  • The 36-month time limit paired with the 46,500-mile mileage threshold means the interval is governed by whichever condition is reached first, so lower-mileage vehicles driven infrequently are still subject to a fluid change within three years under normal use.
  • A separate row entry exists for the CLA 250 4MATIC with a 2023 start year alongside the 2019-2023 entry, both specifying identical rear differential capacity and change interval values of 0.6 liter and 46,500 miles or 36 months under normal use.
