1.6 HDi vs 1.5 / 2.0 EcoBlue: which engine is more reliable?

According to our risk index, the 1.5 / 2.0 EcoBlue carries less risk than the 1.6 HDi: 59/100 versus 71/100 (both high risk). The 1.6 HDi has 2 documented serious faults, the main one being «Turbo failure through lack of lubrication (carbon deposits and union filter)»; the 1.5 / 2.0 EcoBlue has 2 documented serious faults, the main one being «Degradation of the wet timing belt (2.0 EcoBlue)».

Is the 1.6 HDi reliable?

It is an efficient diesel, but its 16-valve versions (2004-2011) have a serious weak point: the turbo is starved of lubrication by carbon deposits from the oil, often made worse by leaks at the injector washers. The 8V engines (from 2010) improved, although you need to watch the 2010-2011 belt and the injectors, and on the BlueHDi the AdBlue tank.[1][2][3][4][5][6][7][8][9]

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.[10][11]
