Common Causes of the Brake Warning Light
Several factors can trigger the brake warning light in your Audi Q7. Let’s examine some of the most frequent culprits:
- Low Brake Fluid: This is the most common cause. Brake fluid levels decrease naturally over time, but a sudden drop can indicate a leak, which needs immediate attention.
- Worn Brake Pads: Your brake pads have wear sensors that trigger the warning light when they reach a certain thickness. This is a normal part of maintenance, and replacing the pads should resolve the issue.
- Faulty Brake Sensor: While designed for durability, brake sensors can sometimes malfunction and trigger the light even when the brake pads are fine.
- ABS Issues: The Anti-lock Braking System (ABS) is a crucial safety feature. If there’s a problem with the ABS module, a sensor, or the wiring, the warning light might illuminate.
