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

According to our risk index, the 2.0 CDTI carries less risk than the 2.0/2.2 D-4D: 38/100 (moderate risk) versus 77/100 (very high risk). The 2.0 CDTI has 2 documented serious faults, the main one being «Turbocharger wear or 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 CDTI reliable?

Unlike the 1.3 and 1.6 CDTI of the same era, the Opel/Vauxhall 2.0 CDTI (2008-2019, 110-210 hp with BiTurbo variants) is an engine with a timing belt rather than a chain. It builds up soot in the injectors and EGR valve, clogs its DPF on short journeys, has a recorded faulty turbo and one engine failure, and its models were among those investigated by Germany's KBA and the Frankfurt public prosecutor over a possible switching-off of the emissions treatment.^{[1][2][3][4][5][6]}

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.^{[7][8][9][10]}
