Audi Power Steering Reservoir Line Hose (R8) - Genuine Audi 420422843G

Product Information

The power steering reservoir hose is a flexible fluid line that connects the power steering fluid reservoir to the power steering pump or return system. It ensures a steady flow of hydraulic fluid, enabling smooth and responsive steering performance. Constructed from reinforced rubber or high-quality synthetic materials, the hose is designed to withstand pressure fluctuations, heat, and exposure to hydraulic fluid. A properly functioning reservoir hose is essential to maintaining system integrity and preventing leaks that could lead to steering issues.

• Visible fluid leaks or seepage around the hose – indicates cracks, wear, or loose connections.
• Low power steering fluid levels – often caused by a leaking or deteriorated hose.
• Stiff or noisy steering operation – results from fluid loss or air entering the system through a damaged hose.

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.
