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.^{[1][2][3][4][5]}

Is the 1.4 D-4D reliable?

Yes, generally: the 1.4 D-4D (1ND-TV) is one of Toyota's most widespread small diesels, with a reputation for reasonable reliability. The documented weak points are the injectors, the turbo, the EGR valve, the diesel particulate filter (on versions that have one) and the clutch and dual-mass flywheel assembly, with cases spread between 2002 and 2018 across the Yaris, Corolla, Auris, Urban Cruiser, Verso-S and MINI One D.^{[6][7][8][9][10]}
