How can I diagnose a faulty ABS system on my Audi 80?

I have been experiencing issues with my ABS system on my Audi 80 and I am not sure how to properly diagnose the problem. I have tried resetting the error codes, but the issue still persists. Any suggestions would be greatly appreciated.

First, it is important to check the brake fluid levels in your Audi 80 as low brake fluid can cause ABS warning lights to appear. If the levels are fine, then the issue may be with the ABS sensors or wiring. It is best to take your car to a mechanic for a thorough diagnosis.

Another common issue with ABS systems on older models like the Audi 80 is corrosion or damage to the ABS wheel sensors. You can check for this by inspecting the sensors and cleaning any debris or dirt that may be blocking them.

If the brake pads on your Audi 80 are worn out, it can also trigger the ABS warning light. Make sure to check the brake pads and replace them if needed. This can sometimes solve the issue.
