2.0 HDi vs 2.0 DTI and 2.2 DTI: which engine is more reliable?

According to our risk index, the 2.0 DTI and 2.2 DTI carries less risk than the 2.0 HDi: 38/100 (moderate risk) versus 55/100 (high risk). The 2.0 HDi has 2 documented serious faults, the main one being «Variable-geometry turbo failures (actuator, sensors and clogging)»; the 2.0 DTI and 2.2 DTI has 2 documented serious faults, the main one being «VP44 injection pump and air mass meter failure».

Is the 2.0 HDi reliable?

It is a robust diesel in its simplest 90 hp version, but the 136 to 140 hp generation with a DPF (2004-2011) concentrates the engine's problems: turbo, DPF, EGR and, above all, a dual-mass flywheel that fails very often. The BlueHDi engines (from 2013) are mechanically more reliable, but add an AdBlue tank that can crystallise; the OCU (Spanish consumer organisation) has reported this fault in Spain and Stellantis covers it with a compensation programme.[1][2][3][4]

Is the 2.0 DTI and 2.2 DTI reliable?

The 2.0 DTI and 2.2 DTI (X20DTH/Y20DTH and Y22DTR) are the direct-injection diesels with a Bosch VP44 pump that Opel fitted between 1997 and 2005 to the Astra G, Vectra B and C, Zafira A, Signum and Omega B. German Wikipedia documents recurring VP44 pump and air mass meter failures in its early years, and a German used-car buying guide singles out the EGR valve as its main weak point even once the engine had matured, in the Vectra C.[5][6]
