Is the BMW M57 reliable?

The BMW M57 (1998-2010) is a six-cylinder diesel with a reputation for great mechanical longevity, capable of exceeding 500,000 km when well maintained, but a good share of the versions built before 2008 -especially with an automatic gearbox- have metal swirl flaps in the intake that can break and wreck the engine; check whether the car has them and what condition they are in before buying.^[1][2][3]

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.^{[4][5][6][7][8]}
