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 2.5 / 3.0 D-4D (KD) reliable?

Toyota's KD diesels (2.5 D-4D, 2KD-FTV, and 3.0 D-4D, 1KD-FTV) have their best-documented weak points in the injectors: the copper seats of the 2004-2007 units, which can block the oil pickup, and the Denso injectors of the 3.0. The 3.0 of the Euro 4 era also has a record of cracked pistons; for the 2.5 we have only found the injector seal problem.[6][7][8][9][10]
