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 1.4 HDi reliable?

It is a small diesel that is generally reliable, but with a very well-documented weakness: the injectors tend to lose their seal over time and let diesel escape. The turbo and the EGR valve also fail on a noticeable minority of units, and there are isolated cases of the crankshaft damper pulley failing at very high mileages. The timing belt does not seem to cause more problems than on any diesel of its era if it is changed on time.^[3][4][5]
