2.2 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 2.2 HDi: 46/100 versus 48/100 (both moderate risk). The 2.2 HDi has 3 documented serious faults, the main one being «DPF clogging with additive, especially on the 128-138 hp version»; 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 2.2 HDi reliable?

This is a diesel derived from the 2.0 HDi that PSA and Ford shared in large saloons and MPVs (407, 607, 807, C5, C6, C8) and that Land Rover and Ford used under their own names (TDCi, TD4, SD4) in the Mondeo IV, the Freelander 2 and the first Evoque. According to fiches-auto it does not suffer chronically from the turbo or dual-mass flywheel problems of smaller HDi engines, but the 128-138 hp version does have a recurring problem of DPF clogging.[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]
