Additional Notes

  • Across all three configurations of the DS 3 Crossback U covered here, the manual transaxle dry fill capacity is 1.8 liters, while the service fill capacity is 1.7 liters. The 0.1-liter difference between the two reflects residual fluid that remains in the unit during a drain, meaning a full service change does not require the same volume as an initial fill on a dry assembly.
  • The 1.2 PureTech 100 with engine code HNK, spanning 2018-2022, carries a normal use condition for its manual transaxle fluid. Under a normal use designation, fluid changes are expected to follow a defined service interval rather than being treated as a sealed, lifetime fill.
  • Both diesel configurations, the 1.5 BlueHDi 100 (YHY, 2018-2022) and the 1.5 BlueHDi 110 (YHS, 2020-2022), are designated as filled for life on the manual transaxle. A filled-for-life designation means the manufacturer does not specify a routine drain-and-refill interval under normal operating conditions, treating the factory-installed fluid as sufficient for the service life of the unit.
  • The 1.5 BlueHDi 110 with engine code YHS has a narrower model year range of 2020-2022 compared to the 2018-2022 range shared by the PureTech 100 and BlueHDi 100 variants, indicating a later introduction for that particular engine configuration.
  • Despite the difference in use condition between the petrol and diesel variants, the transaxle fluid capacities are identical across all three configurations at 1.8 liters dry and 1.7 liters service fill, indicating a shared gearbox assembly regardless of engine type.
