What is the purpose of the ABS module in an Audi 80?

I have noticed that my Audi 80 has an ABS module, but I am not sure what it does or why it is necessary. Can someone explain its purpose and how it works?

The ABS module, or anti-lock braking system module, is responsible for preventing your wheels from locking up during hard braking and maintaining control of your vehicle. It uses sensors to detect wheel speed and applies the brakes in a pulsing manner to prevent skidding.

The ABS module is an important safety feature in your Audi 80. It allows you to maintain steering control while braking, reducing the risk of accidents. Make sure to regularly check the ABS sensor and keep it clean to ensure proper functioning.
