How to repair the ABS warning light on a Jetta?

Confirm the fault condition and symptoms, conduct a visual inspection of the system to check for any brake fluid leaks, damaged wiring, or low brake fluid levels. You can directly read the fault codes using a diagnostic scanner or retrieve the fault codes through the warning light, then refer to the repair manual to identify the fault condition represented by the codes. Based on the interpreted fault condition, use the necessary tools and equipment to conduct an in-depth inspection of the faulty area to confirm the fault location and cause. After the warning light no longer illuminates, perform a road test to confirm whether the system has resumed normal operation.
I usually enjoy tinkering with my car. When the ABS light comes on, start with the simple things first. Turn off the ignition and wait a few minutes before restarting—sometimes minor electronic glitches can resolve themselves. If that doesn’t work, check the sensor probes under each wheel for mud or rust, and clean them gently with a soft cloth. The fuses are located in the engine compartment box—look for the one marked ABS and check for signs of melting. Be careful during the process; you may need to remove the wheels or lift the car to avoid injury. If the light turns off after cleaning, you’ve saved some money. If it stays on, the ABS control module might be faulty—don’t push your luck and get a professional diagnostic scan as soon as possible, as a failed ABS can cause braking skids. When washing your car, pay extra attention to the inner side of the wheels and don’t overlook these sensors.
