2.0 HDi vs BMW N57: which engine is more reliable?

According to our risk index, the 2.0 HDi carries less risk than the BMW N57: 55/100 (high risk) versus 87/100 (very 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 N57 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 N57 reliable?

The BMW N57 (2008-2019, successor to the M57) is a six-cylinder diesel that is mechanically robust in the basics, but it shares with the N47 and B47 the EGR cooler covered by BMW's service campaign for engine fire risk, and it inherits from the N47 the timing chain at the rear of the block, with wear cases documented mainly from 200,000 km. Without a clear history of these checks, it is worth buying with some caution.^[5][6][7]
