Audi ABS Wheel Speed Sensor Wiring Harness - Genuine Audi 80A972254

Product Information

An ABS wheel speed sensor wiring harness is the bundle of wires and connectors that link a vehicle’s ABS (Anti-lock Braking System) wheel speed sensors to the ABS control module. These sensors measure the rotational speed of each wheel, and the wiring harness transmits this information so the ABS system can modulate braking pressure to prevent wheel lockup.

The harness is typically routed near the suspension and wheel assemblies, protected by insulation and clips to withstand heat, moisture, and vibration.

• ABS Warning Light Illuminates: The most common indicator of a faulty sensor or wiring connection.
• Traction Control or Stability Control Warning Lights: These systems rely on wheel speed data; a faulty harness can trigger warnings.
• Intermittent or Erratic ABS Operation: Brakes may engage unexpectedly or the ABS may not activate during hard braking.

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.
