Understanding the Brake Pad Warning Light
The brake pad warning light is part of your Audi A6’s braking system monitoring. Its primary function is to alert you when your brake pads are worn down and require replacement. Ignoring this warning can lead to more extensive and costly repairs down the line, potentially compromising your safety. This light can also indicate issues with the brake pad wear sensor itself or other related components.
Diagnosing the Issue: Why is My Brake Pad Light On?
Several factors can trigger the brake pad warning light in your 2012 Audi A6. The most common culprit is, of course, worn brake pads. However, other possibilities exist.
- Worn Brake Pads: This is the most frequent cause. Over time, brake pads wear down due to friction.
- Faulty Brake Pad Wear Sensor: The sensor itself can malfunction, triggering the light even if the brake pads are fine. These sensors are small wires embedded within the brake pad material. When the pad wears down to a certain point, the sensor wire contacts the rotor, completing a circuit and illuminating the warning light.
- Low Brake Fluid: Low brake fluid can also trigger the warning light, although usually in conjunction with other warning lights. This could indicate a leak in the brake system, a serious safety concern requiring immediate attention.
- Electrical Issues: A wiring problem or a malfunctioning sensor connector can also cause the light to come on erroneously.

What to Do When the Brake Pad Warning Light Comes On
If the brake pad warning light illuminates, the first step is to assess your brake pedal feel. Does it feel spongy or unusually soft? Do you hear any grinding or squealing sounds? If so, pull over safely as soon as possible and have your vehicle towed to a qualified mechanic. If the brake pedal feels normal and there are no unusual noises, carefully drive to a safe location and inspect your brake pads. You can sometimes visually inspect the brake pads through the wheel spokes. However, for a thorough inspection, it is recommended to remove the wheel.

Checking Your Brake Pads
- Safety First: Always use jack stands and wheel chocks when working on your vehicle.
- Visual Inspection: Look for signs of significant wear. If the brake pad material is less than ¼ inch thick, they likely need replacing.
- Professional Inspection: If you are unsure, have a qualified mechanic inspect your brakes.
Resetting the Brake Pad Warning Light
After replacing your brake pads, the warning light needs to be reset. This typically involves using a diagnostic scanner tool. While some vehicles allow for manual resets, the 2012 Audi A6 generally requires specialized equipment.
