Is the 1.5 / 2.0 EcoBlue reliable?

EcoBlue has been Ford's diesel family since 2016, with two very different engines despite the shared name: the 2.0 (codenamed «Panther») debuted a wet timing belt (belt-in-oil) and a second wet belt for the oil pump, the same type of design that has caused problems on other Ford engines; the 1.5, by contrast, uses a conventional dry belt. The 2.0 powers vans, SUVs and large saloons; the 1.5 the smaller models.^[1][2]

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.^[3][4][5][6]
