BMW B57 vs 2.0 and 2.2 CRDi: which engine is more reliable?

According to our risk index, the BMW B57 carries less risk than the 2.0 and 2.2 CRDi: 22/100 (low risk) versus 38/100 (moderate risk). The BMW B57 has 3 documented serious faults, the main one being «EGR cooler leaks on the B57 (limited action on the 540d xDrive)»; the 2.0 and 2.2 CRDi has 2 documented serious faults, the main one being «High oil consumption from worn piston rings and valve guides (2.2 CRDi)».

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 and 2.2 CRDi reliable?

The R family groups the 2.0 CRDi (D4HA, 136-185 hp) of the compact SUVs (Tucson, ix35, Sportage) and the 2.2 CRDi (D4HB, 197-202 hp) of the large ones (Santa Fe, Sorento): Bosch common rail, variable-geometry turbo and chain-driven timing. The 2.2 CRDi can suffer high oil consumption from 100,000 km in the Santa Fe and a turbo that is expensive to repair between 100,000-150,000 km in the Sorento; for the 2.0 CRDi we have not found sources with a specific serious fault.^[3][4][5]
