This is a genuine VAG (Volkswagen Auto Group) harness specifically designed for the speed sensor. It serves as the critical link between the speed sensor and your vehicle's electronic control unit (ECU), transmitting vital data about your car's velocity. A properly functioning speed sensor harness is crucial for several key systems. It directly impacts the accuracy of your speedometer, allowing you to monitor your speed correctly. Furthermore, it plays a significant role in the Anti-lock Braking System (ABS) and Electronic Stability Control (ESC), as these systems rely on precise speed information to operate effectively and ensure your safety. If you are experiencing issues with your speedometer, ABS warning lights, or traction control, a faulty speed sensor harness could be the culprit. Replacing it with this OEM VAG part ensures compatibility and reliable performance, restoring the integrity of these essential vehicle functions.
