Purpose and function in the roof system

The BMW F16 F86 Sunroof Water Outlet Hose Pipe operates in the rear left part of the body, channeling water from the roof cassette gutters outside the passenger cabin. A correctly selected and installed component allows for maintaining the tightness of the drainage system and stable water discharge during rainfall and vehicle washing.

The proper functioning of this hose is particularly important in cars equipped with extensive panoramic roofs, where the volume of drained water is higher and the load on the drainage system is more intensive.

Construction and fitment for BMW F16/F86

The offered hose is part of the Panoramic roofs, sunroofs and parts group, designed specifically for the BMW F16/F86 series architecture. The shape, diameter, and routing of the hose are adapted to the factory mounting points and body channels, which facilitates installation and minimizes the need for additional modifications.

Its placement in the rear left zone of the vehicle allows for maintaining the original drainage installation path, and thus, ensuring a predictable direction of water discharge from the roof.

Benefits of using an original drainage hose

• Factory fitment for the BMW F16/F86 roof structure.
• Stable water drainage from the rear left part of the sunroof cassette.
• Reduced risk of leaks in the headliner and trunk side panel areas.

Application in service, repair, and retrofit

This water outlet hose is suitable for both typical repairs following clogging or damage to the existing installation, as well as for work related to replacing or refurbishing the sunroof cassette. It can also be used in retrofit projects where a complete panoramic roof is installed in place of a standard roof panel.
