What does the Audi 80's ESP light indicate?

I noticed that the ESP light in my Audi 80 turned on while I was driving. What does this indicate and how do I address it?

The ESP light indicates that your Electronic Stability Program is engaged. This system helps to improve your vehicle's stability and control on slippery or uneven road conditions. It is normal for it to turn on when driving on rough terrain or during sharp turns. However, if the light stays on constantly, it could indicate a malfunction in the system.

If the ESP light stays on, it is best to have your vehicle checked by a certified mechanic. They will be able to diagnose and fix any issues with the system. Driving with a malfunctioning ESP system can affect your vehicle's performance and safety on the road.
