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 2.0 BlueHDi reliable?

The 2.0 BlueHDi is mechanically one of the sturdiest PSA/Stellantis diesels: in the samples available for its 150 to 180 hp versions, the turbo, DPF, EGR and injectors fail noticeably less often than on earlier generations of the same engine from before 2013. Its documented weak point is the AdBlue tank, a fault so widespread that Stellantis compensates affected owners without a definitive fix.[3][4][5][6]
