2.0 HDi vs BMW B47: which engine is more reliable?

According to our risk index, the 2.0 HDi carries less risk than the BMW B47: 55/100 versus 73/100 (both high risk). The 2.0 HDi has 2 documented serious faults, the main one being «Variable-geometry turbo failures (actuator, sensors and clogging)»; the BMW B47 has 3 documented serious faults, the main one being «EGR cooler leaks with risk of engine fire».

Is the 2.0 HDi reliable?

It is a robust diesel in its simplest 90 hp version, but the 136 to 140 hp generation with a DPF (2004-2011) concentrates the engine's problems: turbo, DPF, EGR and, above all, a dual-mass flywheel that fails very often. The BlueHDi engines (from 2013) are mechanically more reliable, but add an AdBlue tank that can crystallise; the OCU (Spanish consumer organisation) has reported this fault in Spain and Stellantis covers it with a compensation programme.[1][2][3][4]

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.[5][6][7][8]
