Second Hand BMW i4 Oil Pump

The BMW i4 is a fully electric vehicle, so it has no internal combustion engine and therefore no engine oil pump of the kind found on petrol or diesel cars. Electric motors use different lubrication systems that do not require a conventional oil pump. If you are looking for a cooling or transmission fluid pump for the i4's drivetrain, that is a different component entirely — speak to a breaker about what you actually need and they can advise on the correct part.

It is almost certainly a mistake or a misunderstanding of the part name, as the i4 is fully electric and has no combustion engine requiring an oil pump. It's possible the quote relates to a thermal management pump, a reducer lubrication pump, or another fluid-handling component within the electric drivetrain. Go back to the breaker with your registration number and clarify exactly which pump and which system they are referring to before agreeing to anything.

A standard petrol or diesel 4 Series oil pump would have no application on the i4 whatsoever, since the i4 has no combustion engine for it to fit. The i4 shares its body with the G26 4 Series Gran Coupé but the drivetrains are entirely different. If you need a fluid pump from a donor i4, you would need to source it from another i4 at a breaker — not from a combustion-engined 4 Series.

Trim level is irrelevant here for a straightforward reason: the BMW i4 does not have an oil pump regardless of whether it is an eDrive40, M50, or any other variant, because all versions are fully electric. The eDrive40 and M50 differ in motor output and drivetrain layout, but neither has a combustion engine. If you need a drivetrain fluid pump specific to the M50's dual-motor setup versus the eDrive40's single-motor setup, confirm the exact component with a breaker against your registration.

Depending on the symptom or job you are trying to fix, you may be looking for a coolant pump (the i4 uses active thermal management for its battery and motors), a transmission or reducer lubrication pump, or a heat pump component if your car has that option. Describe your fault or the job to a breaker and give them your registration, as they can identify the correct part from the i4's electric drivetrain rather than guessing from combustion-engine terminology.
