Is the BMW B57 reliable?

The BMW B57 (2015 onwards) is the six-cylinder diesel that succeeded the N57. The sources consulted document no widespread faults: its most cited weak point is the AdBlue/SCR system, and it was left out of the big EGR campaigns that hit the N47 and N57. The timing chain is still at the back, next to the gearbox.^[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]}
