Audi VW Automatic Transmission Oil Cooler Hose Cooler - Genuine VW Audi 1K0121156BF

Product Information

An Automatic Transmission Oil Cooler Hose is a component in vehicles with automatic transmissions that transports transmission fluid between the transmission and the transmission cooler, often located near the radiator. This hose helps keep the transmission fluid cool by circulating it through the cooler, which is essential for maintaining optimal transmission temperature, preventing overheating, and ensuring smooth shifting and transmission longevity.

• Transmission Fluid Leaks: A damaged or worn hose can leak transmission fluid, which may appear as red or brownish spots under the vehicle, particularly near the front
• Low Transmission Fluid Levels: If there is a leak, the fluid level will drop, causing performance issues such as rough or delayed shifting and even overheating
• Transmission Overheating: The cooler hose keeps fluid temperatures down, so a faulty or blocked hose can lead to overheating, which may trigger a warning light on the dashboard

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.
