Purpose and function of the rear window seal

The presented BMW 6 Series E64 E64N LCI Rear Window Bottom Sealing Seal Folding Top has been designed specifically for the rear body zone of the convertible. The component operates in the contact area between the window and the roof structure, where it is responsible for:

• sealing the bottom edge of the rear window against the folding roof cover,
• limiting the ingress of water and moisture into the vehicle interior,
• stabilizing the window during the operation of the roof folding mechanism,
• reducing aerodynamic noise in the rear part of the cabin.

Thanks to its fit for the specific convertible body generation, the seal works with the factory roof mechanism, maintaining the correct geometry and contact line.

Construction and fit for the folding roof

The element is manufactured as a profiled seal intended for installation in the rear part of the vehicle, in the area of the bottom window edge. The design is prepared to work with factory mounting points, which facilitates installation and allows for maintaining proper seal guidance along the entire width of the window.

The appropriately selected stiffness and flexibility of the material promote the proper operation of the folding roof mechanism, minimizing the risk of stress at critical points. As a result, the seal can effectively compensate for the movements of the roof structure during opening and closing, maintaining stable pressure against the window.

Benefits of using the original rear window seal

Using a dedicated seal in the rear body section of the BMW 6 Series E64 / E64N LCI allows for restoring proper folding roof operating conditions and vehicle usage comfort. Key advantages include:

• better rear window tightness in the bottom edge area, which limits the risk of leaks during rainfall and car washing,
• more stable window guidance in the closed position, important at higher speeds,
• reduction of noise in the rear part of the cabin thanks to the proper fit of the seal,
• preservation of the factory geometry of the roof and window lines, which is significant for both utility and aesthetics.

Choosing an original component from the BMW group promotes maintaining the structural integrity of the folding roof and facilitates any potential future service work in this area.

Installation zone and service aspects

The seal is intended for installation in the rear part of the vehicle, in the area of the bottom edge of the folding roof rear window. Replacing the component is particularly recommended in situations where:

• cracks or defects are visible on the edges of the seal,
• leaks occur in the rear part of the roof,
• the roof folding mechanism operates with noticeable resistance in the window area,
• wind noise appears in the vicinity of the rear window at higher speeds.

During installation, it is worth paying attention to the correct positioning of the seal in the guides and even pressure along the entire length to fully utilize its sealing properties.
