2.0 dCi vs 2.0/2.2 D-4D: which engine is more reliable?

According to our risk index, the 2.0 dCi carries less risk than the 2.0/2.2 D-4D: 52/100 (high risk) versus 77/100 (very high risk). The 2.0 dCi has 2 documented serious faults, the main one being «Premature turbocharger failure»; the 2.0/2.2 D-4D has 1 documented serious fault, the main one being «Warped cylinder head gasket and oil consumption on the 2.2 D-4D».

Is the 2.0 dCi reliable?

The 2.0 dCi (M9R) is a Renault-Nissan Alliance diesel with known, well-documented weak points: the turbo and the EGR valve fail relatively often, the particulate filter clogs up in urban use, and there are cases of injectors and even the timing chain failing earlier than expected in several of the models that use it.^[1][2][3][4]

Is the 2.0/2.2 D-4D reliable?

No: the 2.0/2.2 D-4D family is among the most problematic Toyota diesels. The 2.2 block (2AD-FTV and 2AD-FHV D-CAT) has a large number of cases of warped cylinder head gaskets and oil consumption or dilution in the Avensis, RAV4, Auris, Corolla Verso and Verso; the EGR valve and injectors fail frequently across the whole family, and the D-CAT filter clogs up if the car is not driven regularly on open roads.^[5][6][7][8]
