2.0 CDTI vs 2.4 / 2.8 D-4D (GD): which engine is more reliable?

According to our risk index, the 2.4 / 2.8 D-4D (GD) carries less risk than the 2.0 CDTI: 20/100 (low risk) versus 38/100 (moderate risk). The 2.0 CDTI has 2 documented serious faults, the main one being «Turbocharger wear or failure»; the 2.4 / 2.8 D-4D (GD) has no documented serious faults.

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 2.4 / 2.8 D-4D (GD) reliable?

No serious mechanical faults are documented in the European sources we were able to open: AutoBild saw the 2.8 as more robust than the 3.0 it replaced, although it points to glow plugs that fail early. Its best-documented weak point is the particulate filter, with a lawsuit in Australia but no equivalent recall or legal action in Europe, and there are barely any high-mileage examples from which to judge long-term reliability.^[7][8][9]
