Pricing varies based on whether your i4 carries a single camera or the triple-camera ADAS system. Models with the triple-camera array and its associated bracket require more precise recalibration after replacement, which affects the total service cost.
All i4 windscreens are acoustic-laminated as standard, so there's no variation in glass quality between variants — the difference comes down to ADAS calibration complexity.

Our team carries out a parts check to confirm the correct glass and any camera hardware before the technician is assigned.
The technician arrives at your chosen location (mobile at home, or at a workshop if ADAS calibration is needed) with the replacement glass and tools.
The windscreen is removed, the frame is cleaned, and the new acoustic glass is bonded in place. If your i4 has a camera, static calibration is completed immediately after the glass sets.
Your technician confirms the drive-away time before leaving — typically a few hours depending on the adhesive used and ambient conditions.
All replacements are covered by a two-year warranty on workmanship and glass quality, giving you peace of mind.
Most i4 windscreen replacements can be completed at your home or workplace on a mobile basis. However, because all current i4 models feature either a single or triple-camera ADAS system, static camera calibration is required after the glass is fitted.
If the technician has mobile calibration equipment, the entire job — replacement and calibration — can be done at your location. If not, the job is scheduled at a workshop to ensure the cameras are properly recalibrated and your lane-keeping and collision-warning systems function correctly. UKCG matches you with a technician able to handle your specific variant.

Acoustic glass reduces cabin noise for a quieter, more comfortable ride.
Acoustic windscreen glass is laminated with a special acoustic interlayer that absorbs and dampens sound vibrations. It reduces exterior noise—from traffic, wind, and road surface—before it enters the passenger compartment. This makes the cabin noticeably quieter and creates a more peaceful driving experience. It's a comfort feature, not a safety one; standard laminated windscreens already meet impact safety requirements.
Check your windscreen for an ear symbol, the word 'Acoustic', a capital 'A', or the term 'SoundScreen' printed in one of the four corners. These markings indicate acoustic-grade glass. You can also ask your vehicle's dealership or service centre whether your model came fitted with acoustic glass—it's often a factory option on comfort or premium trims.
Acoustic glass is always laminated and bonds to the frame like any standard windscreen, so replacement follows the normal bonded-glass procedure. No specialist calibration is required. The replacement technician will fit it using standard adhesive and sealant. Cure time and drive-away restrictions are identical to standard laminated windscreens. Acoustic glass is widely available as an aftermarket OE-equivalent option.
Green tint reduces glare and improves visual comfort by filtering certain light wavelengths.
Green tint is a light-filtering coating applied to the glass during manufacture. It absorbs and reduces transmission of certain wavelengths of light, primarily to cut glare from sunlight and reflections. The tint is subtle — often barely visible to the naked eye — but measurably improves visual comfort during prolonged driving, particularly in bright conditions. It's a factory specification chosen by the vehicle manufacturer to balance daylight comfort with interior visibility and aesthetic consistency across all glass in the vehicle.
The easiest way to check is to roll your side window halfway down and hold a piece of white paper behind it. Look carefully for a tint cast — green tint will appear as a subtle green hue compared to clear glass. Your windscreen will have the same tint as your side windows. You can also ask your vehicle's dealership or service centre — they'll have the original specification on file.
Green-tinted replacement glass must match the original tint specification to maintain visual consistency across all windows and preserve the vehicle's interior aesthetics. Aftermarket OE-equivalent (OEE) green-tinted glass is widely available, though some vehicles may require original equipment (OEM) dealership glass if the tint specification is proprietary. Tint does not affect calibration, cure time, or installation procedure — it's a cosmetic and functional specification only.
A Head-Up Display projects your speed, navigation cues and key alerts onto the windscreen so you can read them without looking down.
A Head-Up Display (HUD) projects driving information — speed, navigation cues, ADAS alerts — onto the windscreen in your line of sight, so you can read it without taking your eyes off the road. The projector is mounted in the dashboard and shines the image upwards onto a special HUD-compatible windscreen that uses a wedge-shaped laminate to prevent a ghost image. The image typically appears to float a few feet ahead of the car. Common on premium and sports models, increasingly standard on mid-range cars from the 2020s onwards.
Check your vehicle's specification sheet or handbook under 'display features' or 'HUD'. Look for a small projector unit mounted on the dashboard, typically below the steering wheel or in the instrument cluster area. When you start the vehicle, a bright image should appear on the lower windscreen area. Your dealer's service centre can confirm whether your specific model and trim level includes a HUD.
Your replacement windscreen needs to be HUD-compatible — built with the correct wedge laminate so the projected image stays sharp and double-free. Once the HUD-compatible glass is fitted, the projector itself typically doesn't need recalibration: image position is user-adjustable via your dashboard controls. We confirm your vehicle uses the HUD-compatible windscreen variant when ordering, so the replacement matches the original.
Your wipers automatically activate when rain falls on the windscreen.
A rain sensor is a device mounted on or behind the windscreen that detects moisture and triggers the wiper system automatically. The sensor uses infrared light to measure water droplets on the glass surface and signals the vehicle's electrical system to engage the wipers without driver input. This feature improves safety in sudden downpours and reduces driver workload in variable weather conditions.
Check your windscreen for a small sensor unit, usually mounted near the top centre behind the glass or at the base of the mirror. Look for a small dark component or lens. If your vehicle has automatic wipers that activate without you toggling the stalk, you have a rain sensor. Ask your dealer or service centre to confirm; they can check your vehicle records or wiper module settings.
Rain sensors are non-structural elements and do not require recalibration after windscreen replacement. The sensor bracket or mounting may need careful removal and reinstallation to ensure it sits correctly behind the new glass. If the sensor itself is damaged during removal, a replacement unit may be needed. Your fitter will confirm the condition and refit or replace the sensor as part of the standard replacement procedure.
A printed VIN reference box along the bottom edge of your windscreen helps identify your vehicle's chassis number at a glance.
A VIN (Vehicle Identification Number) notch is a small printed or etched box positioned along the lower edge of the windscreen that displays your vehicle's chassis number. This reference marking is a manufacturing and administrative feature, allowing quick visual identification of the vehicle without needing to consult documents. It's particularly useful for service records, insurance claims, and vehicle registration purposes. The notch itself doesn't affect the structural integrity or safety performance of the glass.
Look along the bottom edge of your windscreen — typically in one of the lower corners — for a small rectangular box containing printed digits or characters. If you're uncertain, check your vehicle's service handbook or ask your dealership or service centre to confirm whether your model includes this feature.
When your windscreen is replaced, the new glass will retain the VIN notch printed or etched by the manufacturer. This is a standard feature on replacement windscreens for compatible vehicles and requires no additional work or adjustment. The notch does not affect glass fitting, cure time, or any post-replacement calibration procedures.
A single camera mounted near the rear-view mirror that helps with lane-keeping and collision avoidance.
A mono camera is a single-lens camera positioned behind the windscreen, typically in the upper centre area near the rear-view mirror. It captures the road ahead and uses computer vision to detect lane markings, vehicles, and road hazards. The camera feeds data to driver-assistance systems such as lane-keeping assist, lane-departure warning, and forward-collision warning. It forms the visual foundation of these safety features, allowing the vehicle to monitor road position and surrounding traffic automatically.
Look in the black trim area above the windscreen, centred behind the rear-view mirror — you will see a small triangular lens assembly or dark lens cover. Check your vehicle handbook or ask your dealer's service department to confirm your model has lane-assistance or collision-warning features; vehicles with these systems almost always have a mono camera. Dashboard warning symbols related to lane or collision systems also indicate the presence of this camera.
When the windscreen is replaced, the camera bracket and lens assembly must be removed and carefully repositioned on the new glass. The camera may require calibration after fitting to ensure accurate road detection and lane recognition. Calibration needs vary by vehicle — we confirm the exact procedure when we look up your specific vehicle. The job may take longer than a standard windscreen replacement, and workshop facilities may be required if calibration demands a controlled environment.
Three forward-facing cameras mounted behind the windscreen provide multi-range vision for advanced driver assistance.
A triple-camera system is a forward-sensing array consisting of three separate camera modules positioned behind the windscreen, typically mounted around the rear-view mirror area. Each camera has a different focal length — narrow, main, and wide — allowing the system to monitor the road at different distances simultaneously. This multi-camera approach enables advanced driver assistance features such as adaptive cruise control, lane-keeping assist, collision avoidance, and traffic sign recognition to operate more reliably across a wider field of view and range than a single camera could achieve. The system is a core component of modern vehicle safety and autonomous driving capability.
Look at the windscreen around the rear-view mirror area — you'll see three distinct triangular shapes printed in the black frit (the opaque band around the glass edge). These are the camera housings. Alternatively, check your vehicle documentation or ask your dealer's service centre; they can confirm whether your model is equipped with triple-camera vision.
Triple-camera systems require a precision-engineered bracket and a specifically printed glass variant to align the three optical centres correctly. After windscreen replacement, the camera system may require static or dynamic calibration depending on your vehicle's design — we confirm the exact calibration procedure when we look up your specific vehicle. The replacement glass must be OEM or OEM-equivalent to ensure optical accuracy and system functionality. Calibration restores the cameras' ability to detect road hazards and maintain driver assistance feature performance.
The BMW i4 is a fully electric saloon launched in 2021, combining sporty handling with zero-emission performance. Every i4 windscreen comes with acoustic laminated glass as standard, which reduces road and wind noise — a particularly valuable feature on an electric vehicle where cabin quietness is a selling point.
All i4 variants feature a rain sensor integrated into the windscreen for automatic wiper activation, plus a head-up display that projects speed and navigation onto the glass itself. The VIN (chassis number) is printed along the bottom edge of the windscreen, a modern fitment detail.
Dependending on the specification, your i4 may have either a single front-facing camera or a triple-camera ADAS array behind the windscreen for lane-keeping assist and forward collision warning. Camera-equipped models require recalibration after windscreen replacement — a process completed at a workshop to ensure safety systems function correctly.
