BMW and MINI Publish Updated Windshield Position Requiring OEM Parts and Approved Calibration

BMW has issued updated windshield replacement position statements requiring auto glass companies to use only BMW-sourced original equipment parts and to follow BMW-approved calibration procedures when replacing windshields on BMW and MINI vehicles. The updated bulletins formalize and strengthen the automaker's earlier guidance, which was less explicit about calibration requirements.

BMW bulletin number C-2-0626-5101, titled "Windshield Replacement Standards," addresses both parts selection and the post-replacement calibration process. BMW's stated rationale centers on the role of the windshield in supporting camera-based ADAS systems. The automaker's position is that non-OEM glass may differ in optical properties, thickness, or mounting geometry in ways that could affect camera alignment and ADAS performance after replacement.

The updated position applies to both the BMW brand and the MINI brand, which shares some platform architecture with BMW vehicles. BMW extended similar guidance to headlamp replacements, reflecting a broader OEM posture that precision optical components require OEM-sourced replacements to maintain designed ADAS functionality.

For auto glass shops that service BMW and MINI vehicles, the updated position creates a documentation obligation: shops should retain records showing the part number and source of the glass used and the calibration procedure followed for each replacement. If a shop uses aftermarket glass contrary to the BMW position, it should be prepared to explain that decision to both the vehicle owner and, potentially, to an insurer or adjuster reviewing the claim.

The BMW and MINI position joins similar statements from Ford, GM, Lucid, and other manufacturers that have been published or updated in the 2025–2026 period. The cumulative effect of these OEM position statements is to raise the expected documentation and parts-sourcing standard for the glass replacement industry across a wide range of vehicle brands. Shops serving a diverse customer base should develop model-by-model awareness of current OEM guidance.
