The Audi Brake Pad Wear Indicator Sensor, OEM 8W0615121E (also replaces 4M0615121P), is a genuine used rear right wiring harness that monitors pad thickness and triggers the dashboard warning when replacement is needed. This sensor—sometimes called the brake pad wear indicator—is critical for knowing when pads are dangerously thin. A failing sensor may cause a false warning light or fail to alert altogether, risking rotor damage.
