2.0 dCi vs 1.2 TDI: which engine is more reliable?

According to our risk index, the 1.2 TDI carries less risk than the 2.0 dCi: 45/100 (moderate risk) versus 52/100 (high risk). The 2.0 dCi has 2 documented serious faults, the main one being «Premature turbocharger failure»; the 1.2 TDI has 2 documented serious faults, the main one being «Timing belt, water pump and high-pressure pump».

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.^[1][2][3][4]

Is the 1.2 TDI reliable?

A three-cylinder diesel with a single homologated output (75 hp) that Volkswagen fitted to the low-consumption versions of its smallest models between 2009 and 2014. It belongs to the EA189 family and was added to the list of engines in the emissions scandal a few days later. Its timing belt also drives the water pump and the high-pressure pump, so do not put off replacing it; also keep an eye on the turbo, the EGR and the particulate filter.^[5][6][7][8]
