How can I fix the ABS light on my Audi 80?

My Audi 80's ABS light keeps turning on and off. What could be causing this issue and how can I fix it? I've tried checking the brake fluid and the brake pads but they seem to be fine.

It's common for the ABS light to turn on and off due to a faulty ABS sensor. You should have it checked and replaced if necessary. Also, make sure all of your wheels have good brake pads and that there are no leaks in the brake system.

Another possible cause for the ABS light could be a malfunction in the ABS control module. You may need to have it reset or replaced by a certified mechanic.

Have you recently replaced your battery? Sometimes a low or weak battery can trigger the ABS light to turn on. It's worth checking the battery and its connections.
