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 2.2 MultiJet / BlueHDi (Stellantis) reliable?

The 2.2 diesels of Stellantis's large vans (BlueHDi DW12 in the Boxer, Jumper and Movano; Multijet 3 in the Ducato) are recent engines with no fault statistics of their own. What is documented are campaigns: AdBlue and SCR software, and the fuel return pipe on 2024-2025 units, with a fire risk. Long-term history is missing.^{[4][5][6][7][8]}
