Fitment questions
Do BMW 8 Series cars have electric window switches?
Yes, the BMW 8 Series has always been a flagship grand tourer fitted with full electric windows as standard across all variants, so window switches exist on every version of this model. This applies to both the E31 generation (1990–1999) and the G15/G16/G14 generation (2018 onwards), covering coupe, convertible, and Gran Coupe body styles.
Will an electric window switch from a 2019 8 Series fit my 2021 8 Series?
Both years fall within the current G-series generation (G14 convertible, G15 coupe, G16 Gran Coupe, launched 2018), so there is a reasonable chance of compatibility within the same body style. However, you must match the exact body style and the side — NS (nearside, passenger left) or OS (offside, driver right) — as these are not interchangeable. Confirm the part number against your registration with the breaker before buying.
Does the generation of the 8 Series matter when buying a window switch — will an E31 switch fit a G15?
The E31 (1990–1999) and the current G-series (2018 onwards) are entirely different generations with completely different electrical architectures and switch designs, so parts from one will not fit the other. Always make clear which generation your car belongs to when requesting a quote. The body style and side (NS/OS) must also match within whichever generation you are buying for.
Does the trim level affect which window switch I need on the BMW 8 Series?
Trim level — for example M Sport, xDrive, or M8 — does not fundamentally change the physical window switch fitment, as electric windows were standard across the 8 Series range. You may find minor cosmetic differences in switch surround finish between trims, but these do not affect whether the switch itself will fit mechanically. Confirm the side (NS/OS) and body style with the breaker, as those are the details that actually determine fitment.
Does the body style matter — will a coupe window switch fit a Gran Coupe or convertible?
Yes, body style matters. The G15 coupe, G16 Gran Coupe, and G14 convertible are distinct body styles with different door configurations, so their window switches are not necessarily interchangeable. Always specify your exact body style and the side (NS/OS) when requesting a quote from a breaker to make sure you get the correct switch.
Does it matter which side the window switch is from — can I use a driver's side one on the passenger side?
Yes, side is critical for window switches. NS (nearside, passenger side, left in the UK) and OS (offside, driver side, right in the UK) switches are different parts and will not interchange. Always tell the breaker specifically which side you need, along with your generation and body style, to get the right part.
