Audi VW Output Shaft Seal - Genuine Audi VW 01V409399A

Product Information

An automatic transmission output shaft seal is a critical component that prevents transmission fluid from leaking where the output shaft connects to the driveshaft. It ensures proper lubrication within the transmission and protects it from dirt, debris, and moisture entering the system. Over time, the seal can wear out, harden, or become damaged, leading to leaks and potential driveline issues if not replaced promptly.

• Visible transmission fluid leaks around the driveshaft or under the vehicle.
• Burning smell or smoke caused by leaking fluid contacting hot exhaust parts.
• Unusual noises or vibrations from the driveline due to insufficient lubrication.

About Genuine VW Audi

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

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