BMW B47 vs 2.0 and 2.2 CRDi: which engine is more reliable?

According to our risk index, the 2.0 and 2.2 CRDi carries less risk than the BMW B47: 38/100 (moderate risk) versus 73/100 (high risk). The BMW B47 has 3 documented serious faults, the main one being «EGR cooler leaks with risk of engine fire»; 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 B47 reliable?

The BMW B47 (since 2014, successor to the N47) improves the timing chain tensioner, guides and oil supply and greatly reduces the failure rate of its predecessor, but it is not free of problems: the EGR cooler has been the subject of several BMW technical campaigns for engine fire risk since 2018, and the turbo and particulate filter need careful maintenance.^[1][2][3][4]

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.^[5][6][7]
