How can I troubleshoot a malfunctioning ABS module in my Audi A2?

My Audi A2's ABS (Anti-lock Braking System) module seems to be causing some issues and my ABS light is constantly on. I suspect it may need to be repaired or replaced. I would like some advice on how to troubleshoot this issue.

If your ABS light is on, that means there is an issue with the system. One common cause is a faulty ABS module. Find a reputable mechanic and have them check the module for any faults. If necessary, have them repair or replace it.

Before jumping to the conclusion that your ABS module needs to be repaired or replaced, check the ABS sensors and wiring first. They may just need to be cleaned or replaced. If that doesn't solve the issue, then move on to checking the module.
