What are the common issues with the ABS system in an Audi A2?

I recently purchased a used Audi A2 and noticed some issues with the ABS system. The ABS warning light occasionally comes on and the brakes seem to be stuttering. I want to know the common issues with the ABS system in this specific car so I can properly address them.

The most common issue with the ABS system in the Audi A2 is a faulty ABS module. This can cause the warning light to come on and affect the performance of the brakes. It is recommended to have the ABS module checked and potentially replaced if needed.
