Is the 2.0 TSI / TFSI reliable?

It depends above all on the generation. The earliest units (2008-2012, without Valvelift) have more oil consumption complaints and somewhat more chain and tensioner wear; from 2012 the Valvelift design reduced oil consumption but kept carbon build-up on the intake valves as a weak point until, around 2016, supplementary indirect injection was added. The thermostat housing with the integrated water pump leaks coolant in several generations.^{[1][2][3][4][5]}

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.^[6][7][8][9]
