Is the BMW B58 reliable?

The B58 (3.0 turbo straight-six, since 2015) is considered robust and less troublesome than the N54/N55 it replaced, and the sources do not document widespread internal failures. The known faults are on the periphery: the plastic oil filter housing, crankcase ventilation, gaskets and coolant. On units built before 2021 there are also US reports of an oil pump with a plastic housing.^[1][2][3][4]

See the 6 of the BMW B58 faults

Is the VR6 reliable?

Its best-documented faults are the timing chain, with tensioners on the 12-valve versions and stretching on the 3.2 (R32, A3 8P, TT, Cayenne), and, to a lesser extent, the cooling system of the 12-valve versions. The 3.6 FSI comes out of the sources better than the 3.2.^[5][6][7]
