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 1.8 and 2.0 Zetec-E reliable?

The 1.8 and 2.0 litre Zetec-E engines in the Focus I are simple naturally aspirated petrol engines that, according to the sources, have no recurring serious fault. The most frequently mentioned issue is the plastic thermostat housing, which deforms and leaks coolant; in addition, Ford issued a recall in 2000 to replace the oil filler cap on 1.8 and 2.0 units built up to December 1999.[6][7][8]
