2.0/2.2 D-4D vs 1.9 TDI: which engine is more reliable?

According to our risk index, the 1.9 TDI carries less risk than the 2.0/2.2 D-4D: 66/100 (high risk) versus 77/100 (very high risk). 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»; the 1.9 TDI has 3 documented serious faults, the main one being «Big-end bearing failure».

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.^[1][2][3][4]

Is the 1.9 TDI reliable?

It depends a lot on the version. The rotary pump (1996-2003, codes ALH and AGR among others) has a reputation for great durability. The unit injector system (1999-2010) improves performance and emissions, but has more documented faults: dual-mass flywheel, turbo, EGR valve and, above all in the 105 hp version, cases of broken big-end bearings.^{[5][6][7][8][9][10][11]}
