The brake pad warning light illuminates when the brake pad wear sensors, small metal tabs embedded within the brake pads, make contact with the brake rotor. This contact completes a circuit, triggering the warning light on your dashboard. While worn brake pads are the most common cause, other factors can also trigger the light. Let’s explore them.
Understanding the Audi A6 Brake Pad Warning Light
The brake pad warning light usually appears as a yellow or red symbol on the dashboard, often resembling a circle with parentheses around it. Sometimes, the light is accompanied by a warning message on the driver information display. Understanding the different warning light colors and messages can help you determine the urgency of the situation. For example, a yellow light might indicate that the pads are nearing the end of their lifespan, while a red light could signal a more critical issue.

Understanding when the light comes on is also crucial. Does it illuminate constantly, intermittently, or only when braking? These patterns can offer valuable clues for diagnosis. For instance, a light that flickers on and off could suggest a faulty sensor or wiring problem. Check our guide for the 2013 Audi A6 brake pad warning light for model-specific information.
Troubleshooting the Brake Pad Warning Light
Before rushing to replace your brake pads, it’s essential to diagnose the problem accurately. Here’s a step-by-step guide:
- Visually Inspect the Brake Pads: Carefully examine the brake pads through the wheel spokes. Look for significant wear, where the friction material is thin or almost gone.
- Check the Brake Pad Wear Sensors: Inspect the brake pad wear sensors for damage or dislodgement. Sometimes, a sensor can become detached or damaged, triggering the warning light prematurely.
- Inspect the Brake Fluid Level: Low brake fluid can also activate the warning light. Check the brake fluid reservoir and top it off if necessary. However, consistently low brake fluid could indicate a leak, which requires immediate attention.
- Check for Wiring Issues: Examine the wiring connected to the brake pad wear sensors for any signs of damage, corrosion, or loose connections. A frayed wire or loose connection can disrupt the circuit, causing the warning light to malfunction.
