Toyota 2.0 / 2.2 D-4D (1AD-FTV, 2AD-FTV, 2AD-FHV) · Diesel

Verdict for the versions it uses

• 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.^[2][5]

• 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.^{[2][5][6][7][8][9][10]}

• 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.^[5][6][9]

Faults that affect the Avensis T25

1. Critical severityFrequency: 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. Medium severityFrequency: 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. Medium severityFrequency: 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. Medium severityFrequency: 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.

Toyota 1.4 / 1.6 / 1.8 VVT-i (familia ZZ: 4ZZ-FE, 3ZZ-FE, 1ZZ-FE) · Petrol

Verdict for the versions it uses

• 1.8 VVT-i 125-135 hp (1ZZ-FE, 1,794 cc)2000–2009 · 125–135 hp · 1ZZ-FE

  With caution

  It is the version with the most documented cases of oil consumption (around 13-19% of the Avensis and Corolla Verso testimonials with this engine) and it also accounts for the water pump cases; check the oil history and the condition of the cooling system before buying.^[2][9]

• 1.6 VVT-i 109-110 hp (3ZZ-FE, 1,598 cc)2002–2009 · 109–110 hp · 3ZZ-FE

  With caution

  Fiches-auto.fr documents "high" oil consumption among the Corolla 1.6 VVT-i testimonials, including a case of piston ring failure that required an engine repair costing €5,000 at 110,000 km; check the oil history before buying.^[11]

Faults that affect the Avensis T25

1. Medium severityFrequency: CommonLubricationHigh oil consumption due to piston ring wearYes: a proportion of 1.8 VVT-i (1ZZ-FE) and, to a lesser extent, 1.6 (3ZZ-FE) units use more oil than normal because of piston ring wear. Most of the documented cases are resolved by monitoring and topping up the level, but at least one case ended in an engine repair.
2. Medium severityFrequency: OccasionalCoolingWater pump leak or premature failureYes, in a minority of 1.6 and especially 1.8 VVT-i units: the water pump can start to lose coolant or wear out earlier than expected, in one documented case already at 50,000 km. It is a repair of moderate cost, not a defect that prevents safe driving if detected in time.Appears at around 50,000 km
3. Low severityFrequency: OccasionalElectronicsAir mass meter and lambda sensor failuresOn a minority of Corolla, Avensis and Corolla Verso cars with this engine, the air mass meter (MAF sensor) or the lambda sensor gives wrong readings and lights up the engine warning light; it is a relatively simple repair and does not compromise the engine.
4. Low severityFrequency: OccasionalClutchPremature clutch wear on the manual gearboxOn a minority of Corolla, Avensis and Corolla Verso cars with this engine and a manual gearbox, owners document a clutch replaced earlier than expected, in some cases already at 49,000-53,000 km; the sources describe no cause other than normal wear of the clutch disc.Repair (garage): €1,300–€1,700Appears at around 49,000 km
