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 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]
