What changes in this version

A more powerful version than the launch one but keeping a single turbo, now variable-geometry (not twin-turbo). It was fitted to the Peugeot 4007 and Citroën C-Crosser, the PSA-engined versions of the Mitsubishi Outlander; Land Rover offered a similar output (150 hp) as the 2.2 TD4/eD4 in the Freelander 2 and the first Evoque.[1][2][3][4]

Faults of the DW12 engine

The documented engine faults that affect this version and its years, from most to least important.

  1. 1High severityFrequency: OccasionalTurboTurbo faults, somewhat more frequent on the sequential twin-turbo versionsThe 2.2 HDi comes in single-turbo versions (128-156 hp) and twin-turbo versions with two turbochargers in sequence (170 hp and up). Fiches-auto does not consider it a chronic problem, but it does record a significant number of turbo cases across all power outputs, somewhat higher on the twin-turbos.
  2. 2High severityFrequency: OccasionalInjectionPiezo injector wear and failureThe 2.2 HDi uses third-generation common-rail injection with piezo injectors at up to 1,800-2,000 bar. Fiches-auto documents injector cases across several power outputs, without it being the most repeated fault, with symptoms of hard starting, jerking or higher fuel consumption.
  3. 3Medium severityFrequency: RareClutchDual-mass flywheel wear, less frequent than on other HDi enginesThe 2.2 HDi has a dual-mass flywheel but, unlike smaller HDi engines such as the 1.6 HDi, fiches-auto does not document a chronic problem: very few cases in the tables consulted. Even so, it is a wear part: vibration and knocking are the signs to watch for before buying.
