Second Hand Vauxhall Antara Fuel Injector

Fuel injectors exist on all Antara variants regardless of fuel type — both the petrol and diesel engines use injectors, though the injector design differs significantly between them. Diesel Antaras use high-pressure common-rail injectors, while petrol versions use port or direct fuel injectors depending on the engine. Always confirm your fuel type and engine code with the breaker, as a diesel injector will not interchange with a petrol one under any circumstances.

The Antara ran from 2006 to 2015 with a facelift arriving in 2011, so a 2007 car is pre-facelift and a 2013 is a post-facelift model. Whether injectors cross that 2011 boundary depends entirely on the engine code — if both cars share the same engine code (for example the Z20DMH or Z20DMJ 2.0 diesel), there may be compatibility, but mid-production and facelift changes can affect ancillary specifications. Confirm the engine code from the V5 or a VIN check and run it past the breaker before ordering.

Trim level has no effect on fuel injector fitment — the SE, Club, S, and Elite trims are all cosmetic and equipment-grade distinctions that do not change the engine specification. What matters entirely is the engine code, fuel type, and model year, not the badge on the tailgate. Tell the breaker your engine code and they will be able to match the correct injector regardless of which trim your car is.

Not necessarily, because the 2.0 CDTi engine family covers more than one engine code across the Antara's production run and injector specifications can vary between them. The engine code (found on the V5 or via a VIN check) is the most reliable way to identify exactly which injector your car requires. Give the breaker your full engine code rather than just the capacity and badge, and confirm compatibility before purchase.

Vauxhall used several engines across multiple models during this period, and where the engine code genuinely matches there can be parts commonality — this is worth raising with the breaker. However, ancillary differences such as connectors, rail fittings, or software pairing to the ECU can vary even between cars sharing an engine family, so cross-model fitment should be confirmed against your specific registration rather than assumed. A good breaker will be able to cross-reference the part number against your VIN to give you a reliable answer.

Diesel common-rail injectors often carry calibration codes that need to be programmed into the ECU for accurate fuelling, and this is something your fitting garage or a diagnostics specialist will need to handle. Whether a specific used injector requires coding to your particular vehicle is something to confirm with the breaker and your mechanic rather than something that can be stated as a blanket rule. Make sure you source the injector's calibration data or trim code when buying, as this is often needed at the time of programming.
