Among the several warning lights, the brake lights are more concerning in your Audi.
When you apply the brake pedal, the braking system amplifies the force of your foot on the pedal with the help of brake fluid.
This amplified force of the brake pedal is converting the kinetic energy of the car to heat for slowing it down.
Thus, the activated brake light on the dashboard indicates that your Audi has the following problems.
Most common cause behind the brake light coming on in your Audi is the engaged parking brakes.
If the parking brakes are still active, then the parking brake sensors are forcing the brake warning light to turn on.
The braking mechanism is completely relying on the brake fluid for its smooth operations.
If the reservoir has low brake fluid, then the sensor of the reservoir is triggering the brake warning light on the dashboard.
Modern cars have a sensor that can easily determine the damaged brake pads.
When it happens, the brake light is triggered on the dashboard and decreases the brake fluid level of the car.
Generally, the braking system of the car has sensors for monitoring the brake pad functions and maintaining the brake position.
If the sensor is failed, then the brake light is activated on the dashboard while driving.
When the brake light comes on in your Audi, pull over it carefully in a safe area and turn it off.
