How can I troubleshoot the ABS on my Audi A2?

I have recently noticed that the ABS light on my Audi A2 is constantly on. I have checked the brake fluid level and it is fine. What could be causing this issue and how can I fix it?

First, try to reset the ABS system by disconnecting the battery for a few minutes. Then, check the ABS sensors for any damage or dirt accumulation. Clean or replace if necessary. It's also a good idea to check the wiring and connections for any signs of damage or corrosion.

If the issue persists, it could be a faulty ABS control module. This is a common problem with the Audi A2 and may require a professional diagnosis and replacement. Make sure to check for any relevant recalls or technical service bulletins from the manufacturer.
