Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool if it has been running.

2. Connect OBD-II Scanner

Use an OBD-II scanner to retrieve error codes.
Note any codes related to the traction control system for reference.

3. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level.
If low, top off with the recommended brake fluid (usually DOT 4 for VW).

4. Wheel Speed Sensor Inspection

Jack up the vehicle and remove the wheel to access the wheel speed sensor.
Clean any dirt or debris from the sensor and connector.
Check for any visible damage to the speed sensor or wiring.

5. ABS Module Testing

Reconnect the battery and use an OBD-II scanner to perform an ABS module test.
Follow the scanner instructions to verify module functionality.

6. Replace Faulty Components

If any components (sensors, switches, fuses) are found faulty during inspections, replace them with OEM parts.
Reassemble all components securely.
