2.0 HDi vs 2.2 dCi and 3.0 dCi V6: which engine is more reliable?

According to our risk index, the 2.2 dCi and 3.0 dCi V6 carries less risk than the 2.0 HDi: 46/100 (moderate risk) versus 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 2.2 dCi and 3.0 dCi V6 has 2 documented serious faults, the main one being «3.0 dCi V6 overheating and expansion tank failures».

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 2.2 dCi and 3.0 dCi V6 reliable?

Renault's big 2000s diesels, the 2.2 dCi (G9T) and the 3.0 V6 dCi (P9X), have a poor reputation among owners: big-end bearing failures are cited on the 2.2 and overheating on the V6. The sources are mainly forums and the press that reports them, with no official statistics.[5][6][7]
