What are the most common issues in the ABS system of the Audi A2?

I have been experiencing some issues with my Audi A2's ABS system. I have made sure the tires are properly inflated and the brake fluid is at the right level. However, the ABS light keeps turning on. What could be causing this and what steps should I take to resolve it?

One common issue with the ABS system in the Audi A2 is a faulty ABS sensor. If this is the case, it is important to get it replaced by a certified mechanic to ensure proper function and safety. Another possibility is a problem with the ABS module, which will need to be diagnosed and repaired.
