Is the BMW N57 reliable?

The BMW N57 (2008-2019, successor to the M57) is a six-cylinder diesel that is mechanically robust in the basics, but it shares with the N47 and B47 the EGR cooler covered by BMW's service campaign for engine fire risk, and it inherits from the N47 the timing chain at the rear of the block, with wear cases documented mainly from 200,000 km. Without a clear history of these checks, it is worth buying with some caution.^[1][2][3]

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.^[4][5][6][7]
