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 2.0 FSI reliable?

The 2.0 FSI is the naturally aspirated version with which the Volkswagen Group introduced petrol direct injection in a two-litre engine, before moving on to the turbocharged 2.0 TSI. Two faults recur across several models: carbon build-up on the intake valves, inherent to direct injection, and ignition coil failure, documented from 5,000 km in one case. Gebrauchtwagenberater.de nevertheless counts it among the most reliable petrol engines in the Audi A4 B7.^[5][6][7][8]
