Replacement costs vary with generation and ADAS equipment uptake. Earlier CLA models without windscreen-mounted cameras are typically the most affordable; later variants with driver-assistance cameras and static calibration add complexity and specialist time. Acoustic glass is standard across the range, and many models include rain sensors and green-tinted glass.

From online quote to booked appointment, most customers complete the process in under two minutes.
Most CLA windscreen replacements can be arranged at your home or preferred location. However, if your model carries a forward-facing camera for driver assistance (typically 2022 onwards), static calibration is required after fitting, and this must be performed at a workshop with diagnostic equipment and target boards.
When calibration is needed, the entire job — replacement and calibration together — is scheduled at a single workshop location. This ensures the safety-critical camera alignment is completed without delay and reduces the risk of the system being left uncalibrated.

A camera mounted near the rear-view mirror monitors the road ahead for lane-keep and traffic-sign features.
A forward-facing camera positioned in the windscreen header area (typically mounted on or near the rear-view mirror bracket) captures video of the road ahead. This camera feeds data to driver-assistance systems such as lane-departure warning, lane-keep assist, autonomous emergency braking, and traffic-sign recognition. The camera is a core component of modern ADAS (Advanced Driver Assistance Systems) and requires precise alignment after windscreen replacement to ensure these safety features function correctly.
Look for a small dark triangular or lens-shaped component mounted in the black plastic trim area above the windscreen, typically centred near the rear-view mirror or slightly to one side. Your vehicle's handbook or infotainment menu may reference 'Lane Assist', 'Traffic Sign Recognition', or 'Autonomous Emergency Braking'. Ask your dealer or service centre directly if your car is equipped with a forward-facing camera system.
Windscreen replacement on camera-equipped vehicles requires calibration of the camera system after the new glass is fitted. The exact calibration procedure—whether static (using a target board in a controlled environment) or dynamic (road-based)—varies by vehicle make, model, and year. We confirm the precise calibration requirement when we look up your specific vehicle. Calibration ensures lane-keep, sign recognition, and emergency-braking systems function safely. This may extend the fitting schedule and may necessitate workshop-based fitting rather than mobile attendance.

An aerial laminated into the windscreen or rear window restores radio, DAB or TV reception without a roof-mounted mast.
An antenna is a conductive print laminated into the glass during manufacture, typically used for radio, DAB (digital audio broadcasting) or television reception. It replaces the traditional roof-mounted aerial mast found on older vehicles. The antenna is integrated into the glass interlayer and connected to the vehicle's receiver unit via a connector embedded in the glass edge. This design offers a cleaner aesthetic, reduces wind noise, and eliminates the vulnerability of a protruding mast to damage or theft.
Check your vehicle's roof — if there is no visible aerial mast, your car likely has a laminated antenna. You can also ask your dealer or service centre whether your windscreen or rear window carries an antenna print. The connector may be visible on the glass edge or inside the door frame trim.
When replacing glass with a laminated antenna, the replacement must carry the matching antenna print and connector to restore reception immediately on fitting. Aftermarket or original-equipment glass with the correct antenna specification is essential; a plain replacement will leave you without radio or DAB signal. Our fitters verify the antenna specification during booking and source the correct variant before the appointment.

Heated zones around sensors prevent frost and moisture buildup, helping your safety systems work reliably.
A sensor heated zone is an electrical heating element integrated into or around camera, radar, or sensor mounts on the windscreen. Its purpose is to prevent frost, ice, condensation, and moisture accumulation on sensor lenses and housings. This keeps safety systems — such as lane-keeping assist, collision warning, and adaptive cruise control — functioning accurately in cold, wet, or foggy conditions. Without this heating, moisture or ice can obscure sensors and cause them to malfunction or deactivate.
Check your vehicle's handbook for mention of 'heated sensor zone' or 'sensor heating' in the windscreen or ADAS section. Look at the top edge of your windscreen where cameras or radar modules are mounted — you may see small heating elements or wiring near these components. Ask your dealership or service centre directly: they can confirm whether your specific model includes sensor heating as standard.
Windscreens with heated sensor zones require careful handling during replacement to preserve the heating element and its electrical connections. The heating circuit must be reconnected properly after the new glass is fitted. Depending on the vehicle, this may involve static or dynamic camera calibration after installation. We confirm the exact procedure — including any calibration needs — when we look up your vehicle details.

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. 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.

Dual cameras mounted near the rear-view mirror provide advanced driver-assistance features like collision avoidance and lane-keeping.
A stereo camera is a pair of cameras mounted in the upper windscreen area, typically embedded in or near the rear-view mirror housing. These cameras work together to capture depth information, allowing the vehicle's safety and driver-assistance systems to detect obstacles, measure distances, recognise lane markings, and monitor road signs. Stereo cameras are central to modern collision-avoidance, adaptive cruise control, lane-keeping assistance, and pedestrian-detection systems. Unlike single cameras, the dual-lens setup provides three-dimensional awareness, enabling more accurate decision-making by the vehicle's control modules.
Look in the dark area of the windscreen near the top, directly above or slightly offset from the rear-view mirror. You will see two small lens housings — typically circular or oval — separated by a small gap. Some vehicles display a camera symbol on the dashboard or in the instrument cluster when the system is active. Your vehicle's handbook or service centre can confirm the presence and type of camera system if you're uncertain.
Stereo cameras are bracket-mounted to the windscreen frame and require careful removal and reinstallation during replacement. The camera alignment is critical for safe operation — even small deviations can impair collision detection and lane-keeping accuracy. After windscreen replacement, your vehicle's camera system may require static or dynamic calibration depending on the specific make and model. We confirm the exact calibration procedure and schedule when we look up your vehicle. Calibration ensures the dual lenses are precisely aligned and the depth-sensing algorithms function correctly.
The Mercedes-Benz CLA has been in continuous production since 2012, spanning multiple generations of compact saloons and estates. Early models featured straightforward laminated windscreens with rain sensors and acoustic glass becoming standard across the range.
From the mid-2010s onwards, many variants gained additional features including VIN notches and sensor brackets. More recent CLA models — particularly from 2022 onwards — introduced forward-facing camera systems for Mercedes' Driver Assistance Package, bringing lane-keeping assist, collision warning and sign recognition into the windscreen replacement equation.
Camera-equipped variants require static calibration after the windscreen is fitted, a specialist procedure that's performed indoors with diagnostic targets and is standard practice for Mercedes windscreen replacement.
