Second Hand BMW i4 Fuel Injection Pump

The BMW i4 launched in 2022 as its first generation, so a 2022 and 2023 i4 sharing the same engine code are generally within the same production run and likely compatible. That said, ancillary mounting details and any ECU pairing requirements can vary even within a single model year, so confirm against your exact registration with the breaker before purchasing. The engine code from your V5 or a VIN check is the single most useful detail to give them.

Yes, the engine code is the most important detail for mechanical parts like a fuel injection pump — it tells you exactly which engine variant you have, which the model year alone cannot. Two i4s built in the same year can have different engine codes if they carry different powertrains, so always check your V5 or run a VIN check to get the code before approaching a breaker. Quoting your engine code alongside your registration will get you a far more reliable match.

Trim level does not determine fuel injection pump fitment — what matters is the engine code, fuel type, and gearbox type. The eDrive40 and M50 are different powertrain variants with different motors and drive configurations, so the mechanical components that serve the drivetrain differ between them; however, this is a powertrain difference, not a cosmetic trim difference. Give the breaker your exact engine code and registration so they can match the correct unit, and do not expect a straight swap between these two variants without confirming compatibility first.

This is something you must confirm with the breaker and your fitting garage rather than assume either way, as ECU pairing and immobiliser coding requirements are vehicle-specific and we cannot state a blanket rule here. Some fuel system components on modern BMWs do require coding to the receiving vehicle, and getting this wrong can leave the car undriveable. Ask the breaker whether the unit has been tested and discuss coding requirements with a BMW-specialist garage before committing to the purchase.

The BMW i4 received a facelift in 2024, bringing updates to both exterior styling and some mechanical systems, so parts crossing that 2022–2024 boundary need careful checking. Whether a specific fuel injection pump interchanges across that production change is something you must confirm with the breaker against your exact registration and engine code, as ancillary and mounting changes mid-production can affect compatibility. Name both the donor vehicle's registration and your own when getting a quote so the breaker can check part numbers directly.

Drive configuration — rear-wheel drive as on the eDrive40, or all-wheel drive as on the M50 — reflects a different powertrain setup, and the associated components can differ accordingly. For a fuel injection pump specifically, the engine code and fuel type are the primary fitment factors, but because these drive variants have distinct motors and hardware, you should always quote your engine code and registration to the breaker rather than assuming cross-fitment. Never rely on the badge or drivetrain description alone when sourcing mechanical parts.
