Is the 1.6 TDI reliable?

It depends on the generation. The EA189 (2009-2015, 75-105 hp) is one of the dieselgate engines: it needs the software update and, unlike the 2.0 TDI, an air flow stabiliser, on top of the typical EGR, particulate filter and turbo faults. The later EA288 (from 2012, 80-120 hp) is not singled out by the scandal, but it shares the need to keep an eye on the timing belt and the water pump.[1][2][3][4]

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.[5][6]
