Application of the BMW E90 Sunroof Glass Panel

The presented sunroof glass panel is intended for installation in BMW 3 Series E90 models equipped with a factory sunroof. The component allows for the restoration of proper operation of the roof opening and closing mechanism and the recreation of the original body line.

Panel replacement is particularly recommended in situations such as:

• mechanical damage to the sunroof glass (cracks, chips, scratches),
• closing issues resulting from panel deformation,
• post-accident repairs within the roof area,
• the need to restore the vehicle's factory appearance.

Construction and Technical Characteristics

The sunroof glass panel in the BMW E90 is structurally matched to the sunroof frame and the sliding roof guides. It is responsible for proper guidance along the rails, sealing against gaskets, and effective water drainage from the roof surface.

Key structural features:

• factory fit to the roof opening dimensions in the 3 Series E90,
• edge profile adapted to the sunroof gasket,
• surface designed for operation in varying weather conditions,
• compatibility with the factory tilt-and-slide mechanism.

By maintaining the original geometry, the panel works with the existing mechanism without the need to modify the guides or sunroof frame, which translates to stable operation of the entire system.

Benefits of Using an Original BMW Panel

Using an original sunroof glass panel in the BMW E90 allows for the maintenance of the vehicle's technical and visual consistency. The BMW part ensures:

• precise fit with the sunroof frame and roof panel,
• preservation of factory assembly clearances,
• proper cooperation with gaskets and the water drainage system,
• reduced risk of wind noise and leaks at higher speeds.

For the user, this means less interference with the roof structure, shorter installation time, and the ability to restore sunroof functionality close to its factory state.
