how to fix the ABS light on my Volkswagen Golf MK7 (2015-2019)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface with the engine off.
• Disconnect the battery to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

• Locate the wheel speed sensors at each wheel hub.
• Carefully remove the sensor from the hub without damaging the wiring.
• Clean any dirt or debris from the sensor and the hole using a soft cloth.
• Reinstall the sensor and ensure it is securely connected.

3. Check ABS Module Connections

• Locate the ABS control module, usually near the master cylinder.
• Inspect the electrical connectors for corrosion or loose connections.
• If corrosion is present, clean the connectors with electrical contact cleaner.
• Ensure all connections are tight and secure.

4. Inspect Brake Fluid Level

• Open the hood and locate the brake fluid reservoir.
• Check the fluid level; it should be between the minimum and maximum marks.
• If low, top up with the manufacturer-recommended brake fluid (typically DOT 4).

5. Clear Diagnostic Codes

• Reconnect the battery.
• Use the OBD-II scanner to clear any stored ABS codes.
• Test drive the vehicle to see if the ABS light returns.
