Product Information

Volkswagen Sunroof diagram for Tiguan, Taos

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 VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW 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 VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
