BMW i4 ABS Pump Replacement Parts

Yes, the BMW i4 is fitted with an ABS pump as standard across all variants — being an electric vehicle does not remove the need for ABS, and the system works alongside the regenerative braking setup to manage wheel slip. The ABS pump (sometimes listed as the ABS modulator or hydraulic unit) is a genuine serviceable part on the i4. If you are searching for a used unit, make sure any quote you receive is matched to your exact registration, as the braking system on the i4 is more integrated with the drivetrain electronics than on a conventional car.

The BMW i4 was launched in late 2021 for the 2022 model year and has continued in its first generation through to the current production run, with no fundamental platform change in that period. In principle, units from across this generation may share the same pump hardware, but the i4's brake-by-wire and regenerative braking integration means the ABS module carries software and hydraulic calibration specific to the car's build spec. You should confirm compatibility with the breaker against both registrations before purchasing, as mid-generation control-system updates can affect whether a used unit will operate correctly in your car.

The i4 eDrive40 is rear-wheel drive and the i4 M50 is all-wheel drive with a second motor on the front axle, and this difference in drivetrain layout does affect the braking and stability-control hardware, including the ABS pump and its associated control logic. A pump from an eDrive40 should not be assumed to interchange with one from an M50, and the breaker will need to match the part to the correct drivetrain variant using your registration. Trim level alone (such as interior specification) makes no difference to fitment — what matters here is the powertrain and drive configuration.

No — trim level on the i4 (for example whether the car has higher-spec interior or driver-assistance packages) does not change the ABS pump fitted. What does matter is the drivetrain variant: eDrive40 (rear-wheel drive) versus M50 (all-wheel drive), as these use different braking-system hardware. Give the breaker your full registration so they can confirm the correct unit rather than going by trim name alone.

The BMW i4 shares its bodyshell with the G26 4 Series Gran Coupe, but the i4's braking system is designed around electric-vehicle operation with regenerative braking integration, which means the ABS pump and its hydraulic and electronic calibration differ significantly from those in the combustion-engined G26. You should not assume these units interchange, and a breaker familiar with both platforms will be able to advise whether any overlap exists for your specific build dates and specifications. Always confirm against your registration before buying.

Make sure the breaker matches the part to your registration rather than just the model name, as the eDrive40 and M50 variants use different hardware due to their rear-wheel-drive and all-wheel-drive layouts respectively. It is also worth asking the breaker about the mileage and condition of the donor car, and whether the unit has been tested, given the i4's ABS module is closely tied to the car's regenerative braking and stability systems. Because this is a safety-critical component, professional fitting and coding by a BMW-competent technician is strongly recommended.
