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 2.3 MZR DISI Turbo reliable?

Mazda's 2.3 DISI Turbo (L3-VDT, 2005-2013) is powerful but demanding: the timing chain, the turbo and oil sludge are its weak points; only buy one with a good oil service history.^[6][7][8]
