Cheap BMW i4 Window Winder Motor

The BMW i4 launched in 2021 as a single generation to date, so all i4 models share the same generational body shell — however, you still need to match the correct side (NS for nearside/passenger, OS for offside/driver) as the motors are not interchangeable between sides. The i4 is a four-door Gran Coupé bodystyle only, so door position is consistent across the range, but always confirm the exact door position with the breaker when requesting a quote. Never assume a motor will fit without verifying side and door position against your registration.

Trim level does not affect the fitment of a window winder motor — the door shell and motor mounting are the same across eDrive35, eDrive40, and M50 variants, so a motor from any of those trims can potentially suit your car provided the side matches. You may find minor cosmetic differences in door furniture such as trim panels or finishers between trim levels, but these do not affect the motor itself. Match the side (NS or OS) and confirm with the breaker against your registration to be sure.

The BMW i4 received a facelift for the 2024 model year, and while the overall bodystyle is carried over, it is not confirmed whether window winder motors are directly interchangeable across that facelift boundary. Name the facelift year to your breaker and ask them to check the motor against your specific registration before purchasing, as internal door components can sometimes change at a facelift even when the exterior looks similar. Do not assume compatibility across the 2024 facelift without the breaker's verification.

No — the powertrain, battery size, and electric drive variant (such as eDrive35, eDrive40, or M50 with its dual motors) have no bearing on window winder motor fitment whatsoever. The door mechanism is determined by the body generation and which side of the car you need (NS nearside or OS offside), not by what drives the wheels. Focus on confirming the correct side and door position with your breaker.

Yes, rear window winder motors are side-specific just like front ones — you need to specify NS (nearside, passenger-side left) or OS (offside, driver-side right) when asking for a quote from the breaker. The BMW i4 Gran Coupé has four doors, so both rear NS and rear OS positions exist and use different motors. Always quote your registration to the breaker so they can pull the exact part for your car.

The BMW i4 and the combustion-engined 4 Series Gran Coupé share the G26 platform and the same body shell, which means window winder motors may well interchange between the two — however, you should confirm this directly with the breaker against both registrations rather than assuming compatibility. Side matching (NS or OS) still applies regardless of which model the donor part comes from. A good breaker will be able to cross-reference the part numbers to give you a confident answer before you commit.
