2.2 HDi engine (DW12): faults and reliability

  With caution

  Fiches-auto documents a recurring DPF clogging problem in this version (98 cases out of 277 reviews); check the maintenance history of the DPF and the additive system before buying.^[4]

  Buy

  We have not found reliability tables with documented cases specific to this 150-156 hp version, but nor have we found any recurring problem flagged in the technical tests consulted.^[8][9]

• 2.2 HDi 170-175 twin-turbo (DW12 BTED4, 2005-2010)

  2005–2010 · 170–175 hp · DW12, DW12BTED4, ZSD-422

  With caution

  The two-turbo system adds mechanical complexity; fiches-auto records a significant number of turbo cases in the twin-turbo versions, although, according to the same source, it does not amount to a chronic problem.^[4][6]

• 2.2 HDi 190-204 twin-turbo (DW12 C, 2010-2015)

  2010–2015 · 190–204 hp · DW12, DW12C, ZSD-422

  With caution

  Fiches-auto finds hardly any DPF cases in this version (0 out of 172 and 0 out of 42 reviews), but does find a significant number of turbo cases (16 of 172); check the history of the turbocharging system.^[6]

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.

1. 1High severityCommonFrequency: CommonEmissions controlDPF clogging with additive, especially on the 128-138 hp versionThe particulate filter (DPF) with additive on the 2.2 HDi has a documented recurring problem in the 128-138 hp version (98 cases out of 277 reviews on fiches-auto); the more powerful twin-turbo versions show far fewer cases. The emissions fault warning light comes on and, if ignored, the car loses power.
2. 2High severityOccasionalFrequency: 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.
3. 3High severityOccasionalFrequency: 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.
4. 4Medium severityRareFrequency: 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.

Technical data^{[1][3][5][6][7]}

1. 2000–2006

   2.2 HDi 128-138 (DW12 TED4, single turbo, 2000-2006)

   First generation of the engine: a single turbo and a particulate filter (DPF) with additive as standard. It is the launch engine of the Peugeot 607 (133 hp), the Peugeot 807/Citroën C8 (128-130 hp) and the Peugeot 407/Citroën C5 (136-138 hp).^{[1][10][11][16][17]}

2. 2005–2010

   2.2 HDi 170-175 twin-turbo (DW12 BTED4, 2005-2010)

   It adds a second turbocharger: two fixed-geometry turbos working in sequence (one at low revs, the second joining in from around 2,700 rpm) to reduce response lag without losing low-rev torque. It is the most powerful version in the Peugeot 407, 607 and 807, and the Citroën C5, C6 and C8; Ford used a similar output (155-175 hp) in the Ford Mondeo IV under the name 2.2 TDCi.^{[7][11][12][18][19]}

3. 2006–2012

   2.2 HDi 150-156 (single variable-geometry turbo, 2006-2012)

   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.^[3][5][8][9]

4. 2010–2015

   2.2 HDi 190-204 twin-turbo (DW12 C, 2010-2015)

   Final revision of the sequential twin-turbo, with third-generation common-rail injection up to 2,000 bar and up to 204 hp/450 Nm; it was offered in the second-generation Citroën C5 (Tourer) until the 2.0 BlueHDi versions replaced it. Ford and Land Rover offered an equivalent output (190-200 hp) in the Ford Mondeo IV (from 2010) and as the 2.2 SD4 in the Freelander 2 and the first Evoque.^[2][3][5][7]
