Solution

1. Preparation

Tools Required: OBD-II scanner, basic hand tools, multimeter, brake fluid, safety glasses.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Inspect ABS Fuse

Locate the vehicle's fuse box (refer to the owner's manual for exact location).
Remove the ABS fuse using a fuse puller or pliers.
Check the fuse for continuity using a multimeter; replace if blown.
Reinstall the fuse and reconnect the battery terminal.

3. Check Brake Fluid Level

Remove the cap from the brake fluid reservoir.
Inspect the fluid level; it should be within the "MIN" and "MAX" marks.
If low, fill with the appropriate brake fluid (usually DOT 4 for VW).
Replace the cap securely.

4. Inspect ABS Wheel Speed Sensors

Raise the vehicle with a jack and secure with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Inspect for any physical damage or disconnection.
Clean any debris from the sensor area and reconnect if necessary.

5. Test ABS Pump Operation

Reconnect the battery terminal.
Start the vehicle and engage the ABS system by performing a controlled brake test.
Listen for the ABS pump operation; it should activate briefly when the vehicle is started.
If there is no activation, further inspection of the ABS module may be necessary.

6. Clear Error Codes

Use the OBD-II scanner to clear any error codes that were present.
Take the vehicle for a test drive to ensure the ABS light does not return.
