How to troubleshoot the ABS module in an Audi A2?

I am experiencing problems with my Audi A2's ABS module and would like to do some troubleshooting. What steps should I take to diagnose and fix the issue?

First, check the fuse and relay for the ABS module. If they are fine, then it is likely a sensor issue. Try cleaning the sensors and make sure they are securely connected. If the problem persists, it may be necessary to replace the sensors.

Another thing to check is the ABS module itself. They are known to fail in Audi A2s. If you have access to a diagnostic tool, you can scan for error codes to determine if the module is malfunctioning. If so, replacement is necessary.
