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 1.4 and 1.6 16v reliable?

The K4J (1.4) and K4M (1.6), both naturally aspirated 16-valve units, are simple and generally reliable petrol engines: no source consulted documents oil consumption or faults that destroy the block. Their most-cited weak point is the ignition coils, followed by the crankshaft sensor and, on versions with a variable valve timing unit, its pulley; a neglected belt can cause serious damage, as one case in the Renault Laguna II documents.[6][7][8][9]
