Second Hand BMW X5 Fuel Injector

All petrol BMW X5s have fuel injectors, and so do all diesel variants — diesels use high-pressure common-rail injectors while petrols use port or direct injectors depending on the engine generation, so the part definitely exists across the range but the type varies significantly by engine. You cannot mix petrol and diesel injectors, and you cannot mix different petrol injection systems even if the physical connectors look similar. Always identify your exact engine code (found on your V5 or via a VIN check) before sourcing a used injector from a breaker.

No — the E53 (2000–2006) and E70 (2006–2013) are entirely different generations with different engine families, different injection systems, and different rail and connector designs, so injectors do not cross between them. Even where a similar displacement engine was offered in both generations, the internal engineering changed substantially. Match your injector to your engine code, not the X5 badge or engine size badge on the tailgate.

Both 2009 and 2012 fall within the E70 generation (2006–2013), so you are at least working within the same engine family, which is a good starting point. Whether the injector is a direct swap depends on your specific engine code — for example, the M57 diesel and the N55 petrol require entirely different injectors even though both appeared in E70 production years. Give your engine code to the breaker and ask them to confirm against their donor vehicle's registration rather than relying on year alone.

Trim level and xDrive badging do not affect injector fitment — what matters is the engine code, because the 30d and 40d use different engines (different displacements and different injector specifications) regardless of whether the body is the same. The xDrive four-wheel-drive system is irrelevant to injector selection. Focus on the engine code stamped on your block or confirmed via a VIN check, and give that to the breaker.

The F15 generation ran from 2013 to 2018 with a facelift arriving in 2016–2017, but the facelift was primarily cosmetic and did not involve wholesale engine changes, so injectors from the same engine code should in principle come from the same specification. However, ancillary and mounting changes can occur quietly during a production run without a formal facelift announcement, so you should confirm with the breaker that their donor vehicle's engine code and build date match yours before purchasing. Never assume a part fits based on generation alone.

BMW diesel common-rail injectors, particularly the piezo-electric type found in later engines, do carry calibration data, and whether a used injector needs coding or can simply be swapped is something you must confirm with a qualified BMW technician or the breaker before buying. This is not something we can state as fact for a specific vehicle, as it depends on your engine variant and the calibration tolerance of the injector. Ask the breaker whether the injector comes with its calibration codes and raise the coding question with your garage before fitting.
