2.0/2.2 D-4D engine: faults and reliability

• 2.0 D-4D (1AD-FTV, 116-126 hp, 2005-2018)

  2005–2018 · 116–126 hp · 1AD-FTV

  With caution

  It has documented EGR valve and injector faults as frequent as the 2.2, but head gasket and oil dilution cases are proportionally far fewer in the sources consulted; check the EGR and injector history before buying.^[1][10]

• 2.2 D-4D (2AD-FTV, 136-150 hp, 2005-2015)

  2005–2015 · 136–150 hp · 2AD-FTV

  Avoid

  Several generations and different models (Avensis, RAV4, Auris, Corolla Verso, Verso) repeatedly document head gasket problems, oil consumption or dilution, and EGR and injector faults in this 2.2-litre block; have a specialist workshop check it thoroughly before buying.^{[1][2][3][4][10][11][12]}

• 2.2 D-4D D-CAT (2AD-FHV, 174-177 hp, 2005-2015)

  2005–2015 · 174–177 hp · 2AD-FHV

  Avoid

  This is the version the sources most consistently describe as the most problematic of the whole diesel range of these models, with head gasket, EGR, injector and D-CAT filter clogging faults documented in practically every car that used it.^[2][10][11]

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. 1Critical severityVery frequentFrequency: Very frequentCylinder head and blockWarped cylinder head gasket and oil consumption on the 2.2 D-4DYes: the 2.2-litre block (2AD-FTV and 2AD-FHV D-CAT) has numerous documented cases of warped cylinder head gaskets and oil consumption or dilution in the Avensis, RAV4, Auris, Corolla Verso and Verso, with repairs that sometimes require replacing the engine.Appears at around 40,000 km
2. 2Medium severityVery frequentFrequency: Very frequentEmissions controlEGR valve clogged with sootYes: the EGR valve clogs with soot very frequently across the whole 1AD/2AD D-4D family, especially with urban use and short journeys, and it usually causes a loss of power or the engine warning light to come on.Appears at around 45,000 km
3. 3Medium severityCommonFrequency: CommonInjectionInjector wear and failureYes: the common-rail injectors fail frequently in this family, with cases documented from 30,000 km and repairs ranging from €800 (one injector) to €1,900 (several) according to the owners consulted.Appears at around 30,000 km
4. 4Medium severityCommonFrequency: CommonEmissions controlD-CAT particulate filter cloggingYes: the D-CAT particulate filter, and that of later versions without the badge, becomes saturated with soot if the car does not cover enough open-road miles, with the DPF warning light on and forced regenerations costing around €180 at a workshop.

Technical data^{[5][6][7][8][9]}

1. 2005–2018

   2.0 D-4D (1AD-FTV, 116-126 hp, 2005-2018)

   This is the 2.0-litre (1,998 cc) variant of the family, with less power and torque than the 2.2. It replaced the old 1CD-FTV from 2005-2006 and continued with power tweaks (116, 122, 124, 125 or 126 hp depending on year and model) until the end of European production in 2018, adding a particulate filter in its last versions to meet Euro 5/6.^{[5][6][7][8][9]}

2. 2005–2015

   2.2 D-4D (2AD-FTV, 136-150 hp, 2005-2015)

   This is the standard 2.2-litre variant (2,231 cc), without the D-CAT system, with power outputs from 136 to 150 hp depending on year and market. It was offered from roughly 2005 to 2015 across much of Toyota's mid-range diesel line-up.^[5][6][7]

3. 2005–2015

   2.2 D-4D D-CAT (2AD-FHV, 174-177 hp, 2005-2015)

   It adds the D-CAT system (particulate filter with integrated NOx trap) and raises power to 174-177 hp; it was the most powerful option in the diesel range of these models between 2005 and 2015, and the only one to reach Lexus, in the IS 220d.^{[5][6][7][8][14]}
