Reconditioned Citroën Engine on an exchange basis

15 Citroën engine variants, dozens of engine codes: why engine capacity alone isn't enough

On the Berlingo as on the C5, a 2.0 HDi can conceal very different engine families: the same designation covers codes such as DW10FUC, DW10FUD_AHN, DW10FUE_AHM or RHW, which are not mechanically equivalent. The same applies to the 1.6 HDi, by far the most widespread engine in the Citroën range: between the DV6ATED4, the DV6C (9HR), the DV6DTED and the DV6FD_BHY, successive engine evolutions ran from 1998 to 2026 across models as varied as the C3, the DS3, the Jumpy and the C4 Cactus. Ordering an engine on engine capacity alone risks receiving an incompatible unit.

Petrol, Diesel, PureTech, BlueHDi: the main families to tell apart

On the diesel side, two lineages dominate: the DV6 family (1.4 HDi, 1.6 HDi, 1.6 BlueHDi) and the DW10 / DW12 family (2.0 HDi, 2.0 BlueHDi, 2.2 HDi, 2.2 BlueHDi), to which are added the 1.5 BlueHDi units (DV5RC, DV5RD, DV5RUC) introduced on the more recent generations of the C3, C4 Cactus and Berlingo. The older 1.7 D (XUD7) and 1.9 D / 1.9 TD (WJY, D8A) relate to vehicles built before 2000. On the petrol side, the 1.2 PureTech (EB2 family) and the 1.6 THP / VTi (EP6 / 5F family) cover the C3, C4, DS3, DS4 and DS5, again with several code variants depending on power output and year of production.

Identifying the correct code before ordering

The engine code stamped on the block remains the only reliable identifier — particularly on the Jumper (51 variants of reconditioned engines available), where the 2.2 HDi versions come as 4HG, 4HJ, 4HM, 4HU, 4HV or P22DTE depending on the year and power output. On the C4 and C5, the 2.0 HDi may also appear under codes G6DA to G6DG, or UFBA and UFDB depending on the generation. Checking this code beforehand avoids any ordering error on a bare exchange engine.
