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 TD4 / SD4 reliable?

This is the 2.2-litre diesel of the Freelander 2, the first Evoque, the 2014-2015 Discovery Sport and the Jaguar XF 2.2D. The sources consulted do not describe it as a problematic engine, but they point to three things: the EGR cooler, the DPF in urban use, and replacing the belt along with the water pump.^[3][4][5]
