Is the 2.3 dCi (M9T) reliable?

The 2.3 dCi M9T is a van diesel with good durability if maintenance is kept up. The weak points cited are the EGR and the turbo, the injectors, and the particulate filter in urban use; the sources are mostly opinion websites.^[1][2]

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.^{[3][4][5][6][7]}
