Citroën Jumper Turbo

Citroën Jumper Turbo: 100% diesel, but how many different references depending on the engine?

Unlike some light commercial vehicles that span both petrol and diesel, the Jumper is represented here exclusively in diesel form — from the 2.0 HDi to the 2.8 HDi, including the BlueHDi range. That consistency does not make identification any simpler, however: five distinct engine families are represented, each with its own engine codes and its own turbo references. All parts listed on this page are new turbos, sold as direct-sale items with no old unit to return.

Five engine families, five sets of references

The 2.0 HDi 84 hp (codes 8140.67, RHV/DW10TD, RHV/DW10UTD) and the 2.8 HDi 128 (code 8140.43S) are older-generation fixed-geometry units with a mechanical wastegate: boost pressure is regulated by a valve, with no variable vanes. The 2.2 HDi (codes 4HU, 4HV), covering outputs from 100 to 130 hp, share the same variable-geometry turbo family — but be aware: the four power outputs do not necessarily correspond to a single reference. On the BlueHDi — 2.0 and 2.2, from 110 to 165 hp — codes 4HA, 4HB, 4HH, AHM, AHN and AHP cover a range of six power outputs: engine capacity alone is not enough to determine the correct reference; the engine code stamped on the block is essential.

Symptoms and causes of failure on these commercial engine units

The Jumper is a light commercial vehicle that is frequently operated under load, with demanding thermal cycles. The variable-geometry turbos found on the HDi and BlueHDi generations are prone to vane fouling from soot deposits, leading to whistling, black smoke or loss of power. On wastegate units, a faulty actuator or excessive bearing play results in irregular boost pressure. In every case, identifying and rectifying the root cause of the failure — oil quality, lubrication circuit, blocked diesel particulate filter — is essential before any replacement is carried out, otherwise the new turbo fitted will deteriorate rapidly.
