1.6 TDI vs 2.0 dCi: which engine is more reliable?

According to our risk index, the 1.6 TDI carries less risk than the 2.0 dCi: 45/100 (moderate risk) versus 52/100 (high risk). The 1.6 TDI has 2 documented serious faults, the main one being «Timing belt and water pump»; the 2.0 dCi has 2 documented serious faults, the main one being «Premature turbocharger failure».

Is the 1.6 TDI reliable?

It depends on the generation. The EA189 (2009-2015, 75-105 hp) is one of the dieselgate engines: it needs the software update and, unlike the 2.0 TDI, an air flow stabiliser, on top of the typical EGR, particulate filter and turbo faults. The later EA288 (from 2012, 80-120 hp) is not singled out by the scandal, but it shares the need to keep an eye on the timing belt and the water pump.^[1][2][3][4]

Is the 2.0 dCi reliable?

The 2.0 dCi (M9R) is a Renault-Nissan Alliance diesel with known, well-documented weak points: the turbo and the EGR valve fail relatively often, the particulate filter clogs up in urban use, and there are cases of injectors and even the timing chain failing earlier than expected in several of the models that use it.^[5][6][7][8]
