What are the potential issues with the electronic stability control (ESC) system in the Audi A5?

I recently purchased a used Audi A5 and have noticed that the electronic stability control (ESC) system sometimes malfunctions. In what situations should I be particularly cautious?

The electronic stability control (ESC) system is designed to help prevent your car from skidding in slippery or emergency situations. However, it can malfunction due to rough driving conditions, electrical issues, or a faulty sensor. It's important to be cautious in wet or snowy weather and to have your car inspected by a professional if the ESC warning light illuminates.
