1.5 / 2.0 EcoBlue vs 1.9 TDI: which engine is more reliable?

According to our risk index, the 1.5 / 2.0 EcoBlue carries less risk than the 1.9 TDI: 59/100 versus 66/100 (both high risk). The 1.5 / 2.0 EcoBlue has 2 documented serious faults, the main one being «Degradation of the wet timing belt (2.0 EcoBlue)»; the 1.9 TDI has 3 documented serious faults, the main one being «Big-end bearing failure».

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 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.^{[3][4][5][6][7][8][9]}
