The 1.6 dCi has 2 documented serious faults, the main one being «Premature turbocharger failure or breakage»; 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 1.6 dCi reliable?

The 1.6 dCi (R9M) is a diesel with a generally reasonable track record, but with well-documented known faults: the turbo fails relatively often, even at low mileage, the EGR valve clogs, the particulate filter can block up on short journeys, and there are cases of oil leaks from the timing chain cover that go as far as requiring the engine to be removed.[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]
