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.^[1][2][3]

Is the VM Motori 2.8 and 3.0 CRD reliable?

The VM Motori 2.8 CRD (four-cylinder) and 3.0 CRD V6 diesels from Jeep, Chrysler and Lancia show no systemic fault in open sources: they describe injector wear, a dirty EGR and a high-mileage turbo, and AUTO BILD says durability complaints about the 3.0 are very rare. The UK DVSA identifies only one engine campaign for the 3.0 (2025).^[4][5][6][7]
