When driving an Audi, a brake light coming on can be an alarming experience. It is an indication that something is not right with the braking system, and you need to take immediate action. If you ignore the problem, it can lead to a more serious issue, causing damage to the car and endangering your safety. In this article, we will guide you on what to do when your Audi brake light comes on during driving.

Understanding the Brake System

The braking system is an integral part of your car's safety system, and it is essential to understand how it works. When you step on the brake pedal, it activates the brake pads that press against the brake rotors, causing the car to slow down or come to a stop. The brake light comes on when there is a problem with the braking system that needs immediate attention.

What Causes the Audi Brake Light to Come On?

The Audi brake light can come on due to several reasons. Here are the most common ones:

  • Low Brake Fluid Level: If the brake fluid level in your Audi is low, the brake light will come on. This can be due to a leak in the system or worn-out brake pads.
  • Worn-out Brake Pads: Over time, brake pads wear out and become thin. If they wear out completely, they will damage the brake rotors, causing the brake light to come on.
  • Faulty Brake System: The brake light can also come on if there is a problem with the brake system's components, such as the brake calipers, master cylinder, or brake lines.

What to Do When the Audi Brake Light Comes On?

If the Audi brake light comes on while driving, follow these steps:

  • Don't Panic: Stay calm and avoid sudden braking. Slow down gradually and look for a safe place to pull over.
  • Check Brake Fluid Level: Once you have stopped the car, check the brake fluid level. If it is low, refill it with the recommended brake fluid.
  • Inspect Brake Pads: Check the brake pads for wear and tear. If they are worn out, replace them immediately.
  • Seek Professional Help: If the brake fluid level is fine and the brake pads are not worn out, there might be a problem with the brake system's components. In this case, it is advisable to seek professional help.
  • Avoid Driving: If the brake light continues to stay on, avoid driving the car until the problem is fixed. It is not safe to drive with a malfunctioning brake system.


If the Audi brake light comes on during driving, don't panic. Slow down gradually and follow the steps mentioned above. Remember that the braking system is critical for your safety, and ignoring the problem can lead to severe consequences. Regular maintenance and inspections of the braking system can prevent such issues from happening. It is recommended to take your Audi for servicing every six months to keep the braking system in good condition.
