How to troubleshoot a faulty ABS on an Audi 80?

I've been experiencing strange braking issues with my Audi 80, and I suspect it's related to the ABS system. How can I accurately diagnose and fix the issue?

A common cause for faulty ABS systems on Audi 80 models is a malfunctioning ABS controller. It's best to have this checked and replaced by a certified mechanic.

Check the ABS module for any visible signs of damage or corrosion. It's also worth checking the ABS sensors for any faulty connections or wiring.

In some cases, a simple brake fluid flush and refill can resolve ABS issues on Audi 80 models. It's worth trying this before moving on to more costly solutions.
