Injectors Opel: problems by model and engine

Documented faults, from most to least important

Severity × frequency. Below each one, the Opel models it appears in.

- High severityFrequency: Occasional2.0 DTI and 2.2 DTIVP44 injection pump and air mass meter failureGerman Wikipedia documents recurring failures of the Bosch VP44 injection pump and the air mass meter in the early years of this engine. An owner testimony for this engine describes the pump being replaced at 192,500 km, at a cost the owner calls «prohibitive».
In Astra G, Omega B, Signum, Vectra B, Vectra C and Zafira A
- High severityFrequency: Occasional1.3 MultijetInjector and high-pressure pump wear from contaminated fuelThe Bosch injectors and the high-pressure pump of the common rail system are sensitive to poor-quality fuel or fuel with condensed water. With contaminated diesel they can generate metal shavings that damage first the pump and then the injectors themselves.Repair (garage): €600–€1,200
In Astra J, Combo D, Corsa D, Corsa E and Meriva B
- High severityFrequency: Occasional2.0 BlueHDiInjector and high-pressure pump wearThe injectors and the high-pressure pump on the 2.0 BlueHDi are among the documented faults, although in a minority of the cases recorded compared with AdBlue or the DPF. When the pump fails, metal particles can contaminate the whole circuit and make the repair far more expensive.

- Medium severityFrequency: Common2.0 CDTISoot build-up in the injectors and EGR valveLike many diesels of its generation, the 2.0 CDTI builds up soot in the injectors and the EGR valve, especially on short journeys and in town. An injector replacement has been documented in an Insignia from 105,000 km, and faulty injectors are also cited in an Astra J.
In Astra J, Cascada, Insignia A, Insignia B and Zafira Tourer C
- Medium severityFrequency: Occasional1.7 CDTISoot fouling of the injectors and EGR valveThis engine's EGR valve tends to clog with soot, according to a German buying guide focused on the Meriva A; there are also accounts of misadjusted or faulty injectors from 100,000 km on the Meriva and Astra with this engine.
In Astra H, Astra J, Corsa D, Meriva A, Meriva B and Zafira B
- Medium severityFrequency: Occasional2.3 dCi (M9T)Faulty injectors on the 2.3 dCiSome 2.3 dCi engines show the "injection problem" warning and go into limp mode, sometimes at low mileage. One source indicates between €400 and €1,800 for the repair.Repair (garage): €400–€1,800
