2.0 TSI / TFSI vs 1.8 TCe: which engine is more reliable?

According to our risk index, the 1.8 TCe carries less risk than the 2.0 TSI / TFSI: 32/100 (moderate risk) versus 54/100 (high risk). The 2.0 TSI / TFSI has 2 documented serious faults, the main one being «High oil consumption»; the 1.8 TCe has 2 documented serious faults, the main one being «A110 oil pressure solenoid valve sticking in 2018–2019 cars».

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 TCe reliable?

The 1.8 TCe (M5P) in the Alpine A110 and the Mégane R.S. IV has no documented endemic faults. What has been published are recalls for the A110: the oil pressure solenoid valve (2019) and the fuel pump (2021 and 2023). We have found no recalls or complaints about this engine in the Mégane R.S.[6][7][8][9]
