Second Hand BMW 4 Series Window Switch

The F32-generation 4 Series ran from 2013 to 2020, with a facelift in 2017, and window switches within this generation are broadly similar, but whether a pre-facelift switch crosses cleanly to a post-2017 car is worth confirming with the breaker against your registration. The side matters too — an OS (offside, driver's side) switch is not the same as an NS (nearside, passenger's side) one, so always specify which you need. Never assume a switch fits without checking the exact variant with the supplier.

No — the G22 is the second-generation 4 Series, produced from 2020 onwards, and its switches are entirely different from the F32 (2013–2020) generation in design, connector, and control layout. These two generations do not share window switches, so always source a switch from the same generation as your car. Give the breaker your registration so they can confirm the exact match.

Yes, it matters — the OS (offside, driver's side) front switch typically carries the master control panel for all windows, while the NS (nearside, passenger's side) switch is a simpler single-window unit, so they are not interchangeable. Always tell the breaker which door you need the switch for, and confirm the generation (F32 2013–2020, or G22 2020 onwards) and door count of the donor car matches yours.

Trim level — whether Sport, M Sport, or luxury line — does not generally affect window switch fitment, as these trims share the same door architecture within a given generation. You may notice cosmetic differences in the switch surround or bezel finish between trims, but the functional switch unit itself should be the same. Confirm with the breaker if you want a cosmetically matched finish, though the switch itself can usually be swapped regardless of trim.

The 4 Series is available as a two-door coupe (F32/G22), four-door Gran Coupe (F36/G26), and convertible (F33/G23), and while the window switches serve the same basic function, the door configurations differ between body styles. A switch from a Gran Coupe rear door would not be applicable to a coupe that has no rear doors, so always specify your exact body style and the door position you are sourcing for. Provide your registration to the breaker so they can verify the correct switch for your specific variant.

The 4 Series F32 was facelifted in 2017, bringing updates that may have affected interior components including switch designs, so crossing the pre- and post-facelift boundary is not straightforward. Name the boundary to the breaker — pre-facelift F32 up to 2017 versus post-facelift from 2017 to 2020 — and ask them to check compatibility against both registrations before purchase. Never assume the part crosses the facelift year without that confirmation.
