BMW Sunroof Seal - Genuine BMW 54138218001

Product Information

A Sunroof Seal is a rubber or foam gasket that runs around the perimeter of a vehicle's sunroof. Its primary function is to create a watertight and airtight seal between the sunroof and the roof of the vehicle, preventing water, air, and noise from entering the cabin. The sunroof seal is essential for maintaining the integrity of the sunroof system and ensuring a comfortable driving experience.

• Water Leaks: One of the most common symptoms of a failing sunroof seal is water leakage into the cabin. If the seal is damaged, worn, or improperly seated, rainwater can seep through, leading to wet carpets, headliners, or interior components
• Wind Noise: A degraded or compromised seal can result in increased wind noise when driving, particularly at higher speeds. This noise occurs due to air escaping through gaps where the seal no longer provides a tight fit
• Condensation or Moisture: If the sunroof seal is failing, you may notice condensation or moisture buildup on the interior surfaces of the vehicle, especially during humid weather. This can create an uncomfortable environment and potentially lead to mold or mildew growth

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.
