Audi Convertible Top Hydraulic Line - Genuine Audi 8W7898752

Product Information

Audi Convertible Top diagram for S5, A5 Quattro

A convertible top hydraulic line is a pressurized hose or tube that carries hydraulic fluid between the pump and the hydraulic cylinders, which raise and lower a convertible roof. These lines must withstand high pressure and repeated flexing as the top operates. Over time, exposure to heat, pressure, and movement can cause the lines to weaken or leak, affecting the roof’s function.

• Hydraulic fluid leaks – visible fluid around the convertible top mechanism or under the vehicle.
• Slow or incomplete roof operation – top struggles to move or stops midway due to low fluid pressure.
• Noisy or overworked pump – pump runs louder or longer as it compensates for pressure loss from a leaking line.

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.
