BMW i4 Window Switch Replacement Parts

Yes, the BMW i4 is a fully electric vehicle and is fitted with electric windows as standard across all trim levels, so window switches are present on every variant. The i4 is available as a four-door Gran Coupé body style, meaning there are switches for all four doors. When sourcing a used switch, you'll need to specify which door position you need, as they are side- and position-specific.

The BMW i4 launched in 2021 and all models produced so far fall within the same first generation (G26), so a switch from a 2021 car and a 2023 car are likely from the same generation. However, BMW introduced a facelift to the i4 range in 2024, and parts from before and after that update may differ, so confirm against your registration with the breaker. Never assume fitment across a facelift boundary without checking.

The BMW i4 received a facelift in 2024, and interior trim components including window switches can change across a facelift update. While both generations share the G26 platform, the specific switch design or connector may differ, so this is something you should confirm directly with the breaker using your exact registration. Do not assume pre-facelift and post-facelift switches are interchangeable.

The BMW i4 is offered in trim levels including eDrive35, eDrive40, M50, and xDrive40, but trim level does not typically affect the fitment of window switches as all variants are four-door Gran Coupés with electric windows. The more important factors are which door the switch is for and whether it is NS (nearside, passenger side) or OS (offside, driver side). You may notice cosmetic differences such as finish or button colour between switches from different trim levels, but the physical fitment is what matters.

Yes, window switches are side-specific, and an NS (nearside, left/passenger side) switch will not be the same as an OS (offside, right/driver side) switch. The driver's door switch in particular often differs from others as it typically controls all windows, not just the one door. Always specify NS or OS, and front or rear, when requesting a quote from a breaker to make sure you receive the correct part.

The BMW i4 is built on the G26 Gran Coupé platform, which it shares with the combustion-engined 4 Series Gran Coupé, so there is a reasonable chance that window switches may interchange as the door structures are closely related. However, there can be differences in specification and connector types between variants, so you should confirm compatibility with the breaker by providing both registrations before purchasing. This is especially worth checking if the donor car is from a different model year or trim.
