2.0 CDTI vs 2.2 HDi: which engine is more reliable?

According to our risk index, the 2.0 CDTI carries less risk than the 2.2 HDi: 38/100 versus 48/100 (both moderate risk). The 2.0 CDTI has 2 documented serious faults, the main one being «Turbocharger wear or failure»; the 2.2 HDi has 3 documented serious faults, the main one being «DPF clogging with additive, especially on the 128-138 hp version».

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 2.2 HDi reliable?

This is a diesel derived from the 2.0 HDi that PSA and Ford shared in large saloons and MPVs (407, 607, 807, C5, C6, C8) and that Land Rover and Ford used under their own names (TDCi, TD4, SD4) in the Mondeo IV, the Freelander 2 and the first Evoque. According to fiches-auto it does not suffer chronically from the turbo or dual-mass flywheel problems of smaller HDi engines, but the 128-138 hp version does have a recurring problem of DPF clogging.^{[7][8][9][10]}
