1.2 and 1.4 TSI vs 1.6 THP: which engine is more reliable?

According to our risk index, the 1.6 THP carries less risk than the 1.2 and 1.4 TSI: 64/100 (high risk) versus 84/100 (very high risk). The 1.2 and 1.4 TSI has 3 documented serious faults, the main one being «Timing chain stretch and tensioner failure (EA111)»; the 1.6 THP has 2 documented serious faults, the main one being «Timing chain and tensioner stretch (turbo versions, before 2012)».

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]

See the 5 of the 1.2 and 1.4 TSI faults

Is the 1.6 THP reliable?

The 1.6 THP turbo and its naturally aspirated sibling, the 1.6 VTi, make up the Prince family, developed together with BMW and also used by MINI: they do not have a reputation for reliability. Turbo versions built before 2012 carry a known problem of timing chain stretch, and the whole block shares a water pump described as fragile; the turbo versions add oil consumption and high-pressure fuel pump failures.[6][7][8][9]
