Is the 1.9 D / dTi reliable?

Renault's 1.9 D, 1.9 TD and 1.9 dTi diesels (F8Q, F8Qt and F9Q with an injection pump) have a reputation for longevity, but owner reviews repeat three weak points: the injection pump and cylinder head gasket on the naturally aspirated 1.9 D, and the auxiliary belt, EGR and turbo on the dTi. The common-rail 1.9 dCi is a different engine.^[1][2][3][4]

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.^{[5][6][7][8][9]}
