Is the 1.2 and 1.4 TSI reliable?

It depends on the generation. The chain-driven 1.2 and 1.4 TSI EA111 engines (2006-2015) carry a recognised problem of chain stretch and tensioner failure, and the 1.4 twincharger engines from before 2012 can break pistons. The belt-driven EA211 engines (from 2012) are considerably more reliable: their typical fault is a leaking water pump.[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]
