Is the 1.9 JTD/Multijet and 2.4 JTD reliable?

The 1.9 JTD/Multijet (8v and 16v) and the five-cylinder 2.4 JTD were the world's first common rail diesels and have a reputation for robust, long-lived mechanicals. Before buying, check the known faults: the intake manifold flaps and the EGR valve fail or clog with urban use, the turbo and dual-mass flywheel wear with mileage, and the particulate filter on versions that have one clogs if there are not enough long journeys.^[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]}
