2.0 HDi vs 1.4 TDI: which engine is more reliable?

According to our risk index, the 1.4 TDI carries less risk than the 2.0 HDi: 38/100 (moderate risk) versus 55/100 (high risk). The 2.0 HDi has 2 documented serious faults, the main one being «Variable-geometry turbo failures (actuator, sensors and clogging)»; the 1.4 TDI has 2 documented serious faults, the main one being «Timing belt and water pump».

Is the 2.0 HDi reliable?

It is a robust diesel in its simplest 90 hp version, but the 136 to 140 hp generation with a DPF (2004-2011) concentrates the engine's problems: turbo, DPF, EGR and, above all, a dual-mass flywheel that fails very often. The BlueHDi engines (from 2013) are mechanically more reliable, but add an AdBlue tank that can crystallise; the OCU (Spanish consumer organisation) has reported this fault in Spain and Stellantis covers it with a compensation programme.[1][2][3][4]

Is the 1.4 TDI reliable?

It depends on the generation. The unit-injector one (1999-2010) calls for watching the timing belt - which also drives the unit injector pumps - the water pump, the turbo and the EGR, with a DPF only on the last BlueMotion/Ecomotive versions. The later EA288 (2014-2019) is not singled out by dieselgate, which according to the sources consulted was limited to the EA189, but it shares the need to watch the belt, turbo, EGR and DPF.[5][6][7]
