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 N62 / N63 reliable?

The N62 (naturally aspirated V8, 2001-2010) is considered a solid engine, with the coolant hoses and valve stem seals as points to watch. The N63 (twin-turbo V8, since 2008) has a worse reputation: oil consumption from the seals, the timing chain and coolant loss; the post-July 2013 N63TU is considered more reliable.^{[6][7][8][9][10]}
