Good old Volvo trying it on again. The genuine windscreen requirement is true as aftermarket screens can vary in density causing issues with the camera’s, but it’s not a Volvo main dealer only thing. As a Volvo specialist, we have Volvo’s dedicated diagnostic program, VIDA and this allows us to re calibrate the windscreen sensors should there be an issue after a windscreen has been replaced. Volvo should be supporting their specialist network, rather than sending customers to main dealers charging £150 per hour!
