Audi Disc Brake Pad Wear Sensor - Genuine Audi 80A615121

Product Information

Disc Brake Pad Wear Sensors, or Brake Pad Sensor, as they're commonly called, are used as an instrument to alert the driver when the brake pads of the vehicle are at a low level and are in need of replacement. Operation of the sensor is simple where it is wired to the brake control module with 12v and when the brake pad becomes low enough, the sensor will ultimately surface and make contact with the rotor which in turn grounds the sensor and completes the circuit which triggers the light in your instrument cluster. The Brake Pad Wear Sensor is recommended to be replaced at the time of brake pad replacement.

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.
