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 BlueHDi reliable?

The 2.0 BlueHDi is mechanically one of the sturdiest PSA/Stellantis diesels: in the samples available for its 150 to 180 hp versions, the turbo, DPF, EGR and injectors fail noticeably less often than on earlier generations of the same engine from before 2013. Its documented weak point is the AdBlue tank, a fault so widespread that Stellantis compensates affected owners without a definitive fix.^{[7][8][9][10]}
