Reconditioned Peugeot Boxer Engine

Peugeot Boxer Engine: before and after 2011, two generations of diesel blocks that share no common codes

The Boxer covered here spans the 2006–2021 period and seven diesel engines, from the 1.9 TD to the 3.0 HDi 160. Within this range, the choice between an exchange unit and reconditioning your own part is not trivial: certain second-generation 2.2 HDi blocks carry codes specific to a particular application (ambulance, motorhome, heavy van) that make sourcing on an exchange basis difficult. In such cases, having your own block reconditioned — your own unit is returned to you reconditioned, not replaced with a substitute — is often the only realistic option for maintaining the vehicle's traceability or meeting a registration document requirement.

The 2.2 HDi accounts for the bulk of the identification complexity

With more than thirty-six distinct codes on record (CVF5, CVFF, CYF5, CYFA, CYFB, CYFD, CYFF, CYFG, DRF5, DRFA à DRFF, UHFA, UHFB, SRFA, SRFB, PGFA, QVFA, QWFA, P8FA, P8FB, 4HG, 4HH, 4HJ, 4HM, 4HU, 4HV, DW12RUC_4HH, DW12RUD, DW12RUE, P22DTE_4HG…), the 2.2 HDi is the most widely fitted and most deceptive engine in the range. The same "2.2 HDi" designation can refer to structurally different blocks from the DW12 family, depending on the year of manufacture and body type. The 2.2 HDi 120 (code 4HU) and the 2.2 BlueHDi 120 (code 4HK / DW12RUE) are two distinct sub-families, not interchangeable with earlier HDi blocks.

The other engines: from the 1.9 TD to the 3.0 HDi, low volumes and unique codes

The 1.9 TD (code D8C / XUD9UTF) covers the oldest Boxer models, predating the common-rail generation. The 2.0 HDi comes in five codes (DW10FUC, DW10FUC_AHP, DW10FUD_AHN, DW10FUE_AHM, DW10UTED), each tied to a specific power output or emissions standard. The 2.0 BlueHDi (code 10DYZZ) and the 3.0 HDi 160 (code F1CE0481D / F30DT) each appear as a single entry in the catalogue: their limited production volumes make reconditioning the original unit particularly worthwhile when the block is available and repairable. In every case, the code stamped on the block — not the commercial designation alone — is the only reliable starting point for identifying the exact part.
