Is the BMW B47 reliable?

The BMW B47 (since 2014, successor to the N47) improves the timing chain tensioner, guides and oil supply and greatly reduces the failure rate of its predecessor, but it is not free of problems: the EGR cooler has been the subject of several BMW technical campaigns for engine fire risk since 2018, and the turbo and particulate filter need careful maintenance.[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]
