Vehicle Application and Placement

This seal is dedicated for installation on the rear left door of the BMW F45 body. The component works in direct contact with the side window, responsible for:

• stable window guidance in the track during raising and lowering,
• preventing water and dirt from entering the door interior,
• reducing wind noise at higher speeds,
• maintaining proper window pressure against the door frame.

Precise fitment for the specific mounting location minimizes the risk of leaks and eliminates the need for modifications or adjustments of universal profiles.

Technical and Functional Characteristics

The seal belongs to the group of OEM BMW parts, meaning it retains the factory cross-sectional shape, appropriate rubber compound hardness, and correct geometry of the contact zones. In practice, this translates to:

• proper cooperation with the window lifting mechanism,
• even pressure along the entire edge length,
• reduction of creaks and squeaks during door operation,
• stable seating in the door recess without play.

By maintaining the original specifications, the seal integrates well with the existing door structure, upholstery, and hardware, which is important for professional body repairs.

Condition of the Part and Benefits of Using a Used Part

The offered seal is from the group of used BMW parts, allowing for a reasonable repair cost while maintaining original construction. For rubber and sealing components, using a part from disassembly often provides a better fit than universal aftermarket alternatives.

Choosing an original used seal is a particularly beneficial solution when:

• factory window fitment needs to be restored after a collision or body repair,
• the existing seal is mechanically damaged (cracks, tears, deformations),
• wind noise or leaks appear around the rear left window.

Selection and Compatibility with Replacement Numbers

The part has an assigned OEM part number and associated interchangeable numbers, which facilitates unambiguous identification in BMW catalogs and parts selection systems. This allows for precise verification of the seal's compatibility with a specific body version and vehicle year, without the risk of installing an ill-fitting profile.

Before purchasing, it is advisable to compare the markings with the service documentation or the manufacturer's electronic catalog to confirm that the offered seal matches the factory specifications used in your particular BMW F45 model.
