Used Vauxhall Insignia Throttle Body

Yes, but only on petrol-engined Insignias — diesel engines use a different air management system and do not have a traditional throttle body in the same way. If your Insignia is a diesel (1.6 CDTi, 2.0 CDTi, etc.) you are likely looking for something else, such as a swirl flap, EGR valve, or intake throttle actuator. Check your V5 or run a VIN check to confirm your fuel type before searching.

Both years fall within the Insignia A generation (2008–2017, with a facelift around 2013–2014), so there is a reasonable chance of compatibility if the engine code matches exactly — the engine code is the single most important detail here. However, Vauxhall did make ancillary and mounting changes across the Insignia A's production run, and whether a pre-facelift unit fits a post-facelift car is something you should confirm with the breaker against your specific registration. Always quote your engine code, which you can find on your V5 or via a VIN check.

The Insignia B (2017 onwards) is a completely different platform from the Insignia A (2008–2017), and the two generations are not interchangeable for mechanical components like a throttle body. Engine codes changed significantly between generations, so even if the engine size sounds similar, the parts will differ. Confirm your engine code with the breaker and search specifically for Insignia B parts if your car is a 2017-onwards model.

Trim level does not affect throttle body fitment — the SRi, SE, Design, Elite, and other Insignia trims all use the same throttle body as long as the engine code matches. What matters is the engine code, not the badge on the back of the car. Do be aware that differences in ancillary brackets or sensors between individual cars can exist, so always confirm the part against your registration with the breaker.

This is an area where you should confirm directly with your fitting garage or the breaker, as ECU pairing and whether the Insignia's throttle body requires coding to the vehicle is not something that can be stated as a blanket rule. Some throttle bodies on modern Vauxhalls do require a throttle body relearn procedure after fitting, and in some cases ECU interaction may be involved. Ask your mechanic before buying a used unit so you know what to expect.

The most important detail is your engine code, which appears on your V5 registration document or can be obtained via a VIN check — this identifies the exact variant of your engine and ensures the breaker supplies the correct unit. You should also provide your registration number, the model year, and confirm whether your car is petrol or diesel (diesels generally do not use a conventional throttle body). Breakers on Findapart will use these details to check compatibility against their stock before quoting you.
