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 2.0/2.2 D-4D reliable?

No: the 2.0/2.2 D-4D family is among the most problematic Toyota diesels. The 2.2 block (2AD-FTV and 2AD-FHV D-CAT) has a large number of cases of warped cylinder head gaskets and oil consumption or dilution in the Avensis, RAV4, Auris, Corolla Verso and Verso; the EGR valve and injectors fail frequently across the whole family, and the D-CAT filter clogs up if the car is not driven regularly on open roads.^[3][4][5][6]
