Additional Notes

  • The 1.2 PureTech 100 (HNE) and 1.2 PureTech 130 (HNS) transaxles share an identical 1.7-liter service fill capacity, meaning the specified volume applies to a fluid change rather than a complete drain and rebuild of the unit.
  • The Citroën C4 III 1.5 BlueHDi 110 (YHS) carries a slightly larger transaxle capacity of 1.8 liters, which is 0.1 liters more than either PureTech petrol variant.
  • The 1.5 BlueHDi 110 transaxle is designated as filled for life, a classification indicating the manufacturer does not specify a routine drain-and-refill interval under normal operating conditions.
  • Both PureTech variants list their capacity explicitly as a service fill, confirming the 1.7-liter figure is the working volume used when performing a periodic fluid change on the transaxle.
  • The 1.5 BlueHDi 110 (YHS) coverage runs from 2020 through 2023, while the two PureTech petrol transaxle specifications carry a starting year of 2020 without a closing year in the data.
  • All three configurations are noted as transaxle, manual units, meaning the gearbox and final drive share a common fluid sump, which is why a single capacity figure covers the entire assembly in each case.
