Understand the repair
What this service does
Modern cars, especially Range Rover and BMW models, feature Advanced Driver Assistance Systems (ADAS) mounted on the windshield. When the glass is replaced, these cameras must be aligned to ensure they 'see' the road accurately. This calibration process synchronizes the digital sensors with the physical position of the new glass.

What you may notice
Signs you need this service
- Lane departure warning errors
- Automatic emergency braking malfunction
- Adaptive cruise control not engaging
What can cause the problem?
- Replacing the windshield shifts the camera mounting point by even a fraction of a millimeter.
- Disconnecting the sensor array during glass removal triggers a system reset requirement.
- Suspension changes or heavy impacts can also knock these sensitive cameras out of alignment.
From inspection to finish
How the work is carried out
Inspect and identify
Technicians connect diagnostic equipment to the vehicle's onboard computer to check for fault codes. We ensure the car is parked on a perfectly level surface for accurate measuring.

Repair the confirmed fault
We use specialized aiming targets or dynamic driving tools to calibrate the camera's field of vision. The software is updated to recognize the new windshield's optical properties.

Check the result
A final system test is performed to confirm all safety features are functioning correctly. We provide a digital report showing the successful calibration of the sensors.
The exact procedure depends on your vehicle and inspection findings. A technician confirms the work before repair.
Why it matters
Incorrectly calibrated cameras may lead to unprompted emergency braking or failure to detect obstacles. This creates a significant safety hazard for the driver and other road users.
Before you drive
Never obstruct the camera's view on the windshield with stickers or tinting film.
