Is the 2.0 CDTI reliable?

Unlike the 1.3 and 1.6 CDTI of the same era, the Opel/Vauxhall 2.0 CDTI (2008-2019, 110-210 hp with BiTurbo variants) is an engine with a timing belt rather than a chain. It builds up soot in the injectors and EGR valve, clogs its DPF on short journeys, has a recorded faulty turbo and one engine failure, and its models were among those investigated by Germany's KBA and the Frankfurt public prosecutor over a possible switching-off of the emissions treatment.^{[1][2][3][4][5][6]}

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.^{[7][8][9][10]}
