What does the red indicator light in my Audi 80 mean?

I noticed a red indicator light shaped like a car with an exclamation mark in my Audi 80 dashboard. What does it mean and how should I address it?

The red indicator light in your Audi 80 is the warning light for your brake system. It could mean several things, such as low brake fluid or a malfunction in the brake system. It is important to have it checked by a mechanic as soon as possible to avoid any potential danger.

The red indicator light in your Audi 80 could also indicate an issue with the electronic stability control (ESC) system. It is recommended to stop the car and perform a basic troubleshooting by turning the ignition off and then back on. If the light is still on, it is best to take your car to a certified mechanic for further inspection.
