Second Hand BMW M4 Windscreen

The F82 M4 ran from 2014 to 2020, so a 2015 and a 2018 car share the same generation and a windscreen from either year should be broadly compatible in terms of glass shape and fitment. However, you must check whether both screens carry the same ADAS camera bracket and whether heating elements are present, as these features varied across the production run and a mismatch will cause problems. Confirm the exact specification against your registration with the breaker before buying.

The F80 M3 and F82 M4 are closely related but are different body styles, and their windscreens are not the same shape or size, so they are not interchangeable. Stick to sourcing an F82 M4 windscreen for your car, and confirm the ADAS bracket and heating specification with the breaker against your registration.

Trim level and model designation such as Competition do not affect windscreen fitment on the M4 — what matters is the generation, whether a heated windscreen is fitted, and whether an ADAS camera bracket is present. You may find a screen sourced from a Competition car looks identical to one from a standard M4, so do not pay extra simply because it came from a Competition model. Focus your checks on generation and whether the glass matches your heated and ADAS setup, and confirm those details with the breaker.

The F82 M4 received a facelift in 2017 bringing a number of updates, and while the fundamental body structure remained the same, ADAS camera brackets and heated-glass fitment became more common on later cars. The glass shape may physically fit across the facelift boundary, but crossing that boundary is exactly the kind of interchange where you need to confirm compatibility with the breaker against both registrations rather than assume it will work. Do not assume pre- and post-facelift screens are a straight swap without that check.

Look for a mounting bracket or housing at the top centre of the inner face of your current windscreen, usually accompanied by wiring or a camera unit attached to it — if your car has lane-keeping assist, automatic emergency braking, or similar systems, it almost certainly needs a screen with a compatible bracket. Whether the bracket on a used screen is compatible with the specific ADAS system fitted to your car is something you should confirm with the breaker against your registration, as there are variations that are easy to miss. Getting this wrong can mean your safety systems do not function correctly after fitting.

Yes, this matters — if your car left the factory with a heated windscreen, fitting an unheated replacement means the heating function will simply not work, and the wiring will have nowhere to connect. Heated windscreens are increasingly common on newer M4s and are easy to overlook when sourcing a used screen, so always check your original glass for the heating elements and ask the breaker to match the specification exactly.
