An Electronic Parking Brake (EPB) control switch is a cabin-mounted control that electronically engages or releases the parking brake, replacing the traditional handbrake lever. When activated, it sends a signal to the brake actuator motors, which apply or release the rear brakes. The EPB switch enhances convenience, saves interior space, and often integrates with safety features like hill-hold assist.

• Parking brake warning light illuminated on the dashboard.
• Failure to engage or release the parking brake when pressing the switch.
• Intermittent or unresponsive operation, often due to electrical faults or switch failure.

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.
