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 M54 reliable?

The BMW M54 (2000-2006) is a naturally aspirated petrol inline-six with a reputation for longevity, passing 200,000 km if maintained. Its weak points are the crankcase ventilation valve and the plastic cooling system; check that they have been renewed.^[6][7][8]
