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]

Is the 1.6 and 2.0 8v EA827 reliable?

Simple, naturally aspirated petrol engines that, according to the sources, last a long time with regular maintenance. Gebrauchtwagenberater describes the 8-valve 1.6 as old-fashioned but reliable, and the 102 hp 1.6 MPI as even more reliable than the 1.4 16v. Watch the timing belt with the water pump, coolant leaks, oil consumption (especially on the 2.0) and idle and sensor faults.[5][6][7][8]
