2.0 HDi vs Skyactiv-D: which engine is more reliable?

The 2.0 HDi and the Skyactiv-D tie on our risk index: 55/100 (high risk). The 2.0 HDi has 2 documented serious faults, the main one being «Variable-geometry turbo failures (actuator, sensors and clogging)»; the Skyactiv-D has 3 documented serious faults, the main one being «Oil dilution with diesel during DPF regenerations».

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 Skyactiv-D reliable?

The Skyactiv-D is a modern and generally reliable diesel, but across its three displacements (1.5, 1.8 and 2.2) it shares oil dilution with diesel fuel during diesel particulate filter regenerations, which means you need to watch the oil level and not stretch oil changes, especially on short journeys; the older 2.2s (2012-2014) also accumulate more turbo and carbon build-up cases.^[5][6][7][8]
