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 1.6 / 2.2 i-DTEC reliable?

The i-DTEC is Honda's diesel family from 2008, with two four-cylinder blocks: the 2.2 (Accord, CR-V) and, from 2013, the 1.6 (Civic, CR-V, HR-V). It uses a timing chain instead of a belt and common-rail injection. The basic architecture has a good reputation for longevity, but the emissions system (DPF and EGR) and the turbocharger account for most of the faults documented by owners themselves.^[5][6][7][8]
