Audi Master Cylinder Pin - Genuine Audi WHT001666

Product Information

The clutch master cylinder is a critical component of a hydraulic clutch system in manual transmission vehicles. It is responsible for converting the mechanical force applied by the driver’s foot on the clutch pedal into hydraulic pressure, which then engages or disengages the clutch. The master cylinder is connected to the clutch pedal and the slave cylinder via a hydraulic line.

• Difficulty Engaging or Disengaging the Clutch: A failing master cylinder can make it hard to press the clutch pedal down or may result in the clutch not fully disengaging, causing difficulty in shifting gears
• Spongy or Soft Clutch Pedal: If there are air bubbles in the hydraulic system due to a leak or failure, the clutch pedal may feel spongy or soft, requiring more effort to engage the clutch
• Fluid Leaks: Visible leaks around the clutch master cylinder or along the hydraulic line can indicate a failure. This may be noticed as fluid pooling under the vehicle or around the clutch pedal area

About Genuine Audi

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.
