Audi Door Seal - Genuine Audi 8W0831721C

Product Information

Door seals are essential components that prevent water, air, and debris from entering the vehicle's cabin. They also help to reduce road noise and maintain the interior climate.

• Cracking or tearing: Over time, exposure to the elements and frequent use can cause the rubber material to degrade, leading to cracks or tears.
• Shrinkage or compression: Temperature fluctuations can cause seals to shrink or compress, creating gaps that compromise their effectiveness.
• Water leaks or wind noise: Damaged or worn-out seals can result in noticeable water leaks during rain or increased wind noise at higher speeds.

About Genuine Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

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

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct 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.
