Used BMW i3 Fuel Injection Pump

The BMW i3 is a battery-electric vehicle in all of its mainstream UK variants, meaning it does not have a combustion engine and therefore does not use a fuel injection pump at all. If you have been quoted for this part against an i3 registration, it is worth double-checking the vehicle details, as there may be a data entry error or a mix-up with another model. Contact a breaker with your exact registration number so they can verify what is actually fitted to your car.

The i3 Range Extender (REx) does carry a small two-cylinder petrol engine, so a fuel injection pump is a genuine fitment question for that variant. However, the standard i3 is fully electric and has no combustion engine whatsoever, so a pump from a REx model would have nothing to fit onto a non-REx car. Always confirm with the breaker using your registration so they can match the correct REx engine specification to your vehicle.

No — trim levels such as the standard i3 REx, Suite, and Loft editions are cosmetic and interior distinctions only and have no bearing on mechanical components like the fuel injection pump. The part follows the engine specification, not the trim badge, so a pump from a lower-spec REx is mechanically the same candidate as one from a higher-spec REx of the same generation. Confirm the engine code with the breaker against your registration to be certain you are getting a correctly matched unit.

The BMW i3 received a notable update around 2017 (sometimes referred to as the 94Ah refresh), and while the Range Extender engine carried across the model's life, ancillary components and mounting details can change between production runs. You should name the generation boundary — pre-2017 versus 2017-onwards — when speaking to a breaker, and ask them to confirm interchangeability for your specific registration rather than assuming the pump crosses that boundary. The engine code, which you can find on your V5 or via a VIN check, is the single most useful detail to supply.

If your i3 is the standard battery-electric model — which covers the vast majority of UK i3s — it has no combustion engine and therefore no fuel injection pump. Only the i3 Range Extender (REx) variant carries a petrol engine and could require this part. Check your V5 or use a VIN check to confirm whether your vehicle is a REx before ordering, and share that information with the breaker so they can source the right component.

This is something you must confirm directly with the breaker rather than assume, as ECU pairing and immobiliser coding on used components can vary between vehicles and may require specialist attention. A breaker experienced with BMW i3 REx parts should be able to advise whether the pump they hold is likely to need coding to your vehicle. Never assume a used pump will be plug-and-play without checking first.
