BMW F07 Back Door Boot Lid Gutter Strip Trunk Lid Bottom Rubber Seal 7220159

BMW F07 Back Door Boot Lid Gutter Strip Trunk Lid Bottom Rubber Seal is an original body component from the Window seals and trims category, designed for BMW 5 Series Gran Turismo F07 models. It ensures tight water drainage from the bottom edge of the tailgate, reducing the risk of moisture in the trunk and protecting electrical components. Thanks to its factory profile and precise fit for this specific body version, it is a practical solution for post-collision repairs or fixing leaks.

Purpose and function of the seal

The presented trunk lid bottom seal acts as a gutter that drains water from the rear part of the BMW F07 body. Its tasks include:

• sealing the contact point between the bottom edge of the tailgate and the body shell,
• directing water runoff away from the trunk compartment,
• preventing moisture from entering the upholstery and side recesses,
• protecting electrical system components in the rear of the vehicle. Thanks to its factory profile, the seal works in harmony with the tailgate and body contours, which translates into stable adhesion and consistent sealing every time the trunk is closed.

Construction and fit for BMW F07

The seal has been designed specifically for the tailgate structure of the BMW 5 Series Gran Turismo F07, taking into account the characteristic geometry of this model. The properly formed cross-section and material flexibility allow for:

• precise placement in factory slots and clips,
• maintaining shape along the entire length of the bottom edge of the tailgate,
• reducing vibrations and squeaking while driving,
• a visually consistent contact with other body seal elements. Its original BMW origin ensures compatibility with factory mounting points, which facilitates work for body shop technicians and mechanics repairing the rear of the vehicle.

Application in repairs and leak diagnostics

Replacing the bottom trunk lid seal is recommended especially in situations where the following occur:

• traces of water or moisture in the trunk compartment,
• fogged windows after prolonged parking,
• corrosion around the trunk sill or side recesses,
• mechanical damage to the seal after a collision or tailgate disassembly. Choosing an original seal from the same model group reduces the risk of poor fitment, which often occurs with universal profile replacements. It is a practical solution for comprehensive rear body renovation, especially in vehicles operated in harsh weather conditions.

Characteristics of the used part

The offered seal is a used component, sourced from a dismantled BMW vehicle. Such components retain their factory shape and fit, which is crucial for sealing elements where precise adhesion to the tailgate and body shell is essential. In practice, this allows for:

• preserving the original sealing geometry,
• reducing repair costs compared to a new part,
• maintaining consistency with other body seals. Choosing an original, used seal is often preferred by workshops specializing in BMW, which prioritize factory fit and predictable behavior of the element after installation.

Complementary elements and technical knowledge

If you are planning a comprehensive repair or upgrade of the body sealing zone in your BMW and need other elements from the same group, such as additional edge seals, trim strips, or window profiles, check the available parts in the BMW window seals and trims category. When working with dismantled parts, it is worth knowing the best practices for selecting used components – material describing how to safely choose parts from the secondary market, including fuel system elements, may be helpful.
