Application and Compatibility

The presented roof glass is intended for BMW 1 Series vehicles in E81 and E87 body styles equipped with a factory sunroof. The design, based on manufacturer solutions, ensures:

• correct fit to the sunroof frame and roof panel,
• maintenance of body lines and proper seal adhesion,

Therefore, replacing a damaged glass with this component allows for restoring the correct sunroof functionality without interfering with the roof structure or guides.

Technical Characteristics of AS3 Glass

AS3 type roof glass belongs to the group of automotive glass with specific light transmission and tinting parameters, which affects thermal comfort and reduces interior heating. In practice, this means:

• reduced sunlight penetration into the cabin,
• better protection of the interior against upholstery fading,
• more comfortable driving conditions on sunny days.

As a component from the automotive glass category, the roof glass works with the factory water drainage system in the sunroof frame, which is important for maintaining sealing and protection against leaks.

Item Condition and Benefits of Installation

The offered roof glass is a used part, sourced from disassembly, which allows for maintaining the original manufacturer's specifications while reducing repair costs. Choosing this solution is particularly beneficial when:

• the sunroof glass has cracked or shattered,
• there are leaks resulting from previous, unprofessional repairs,
• you want to restore the vehicle to a factory-like condition using OEM parts.

Installing an original roof glass helps maintain the correct structural rigidity around the roof opening and proper sunroof operation throughout its range of movement.

Selecting Roof Glass by Part Numbers and Designations

This BMW roof glass has a dedicated OEM part number and associated replacement numbers, which facilitates precise identification in manufacturer catalogs and parts selection systems. Before purchasing, it is advisable to compare the designations from the glass's rating plate or the vehicle's documentation to confirm full compatibility with your specific equipment version.

The product description provides information such as the stock identifier, manufacturer part number, and reference numbers, which allow you to verify compatibility with your BMW 1 Series. This minimizes the risk of purchasing an incorrect part and allows you to plan the installation as a plug-and-play operation at a specialized service center.
