what does the ABS light mean on my Volkswagen Golf MK7.5 (2020-Present)

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and turn off the engine.
• Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace ABS Wheel Speed Sensors

• Tools Required: Socket set, multimeter, torque wrench.
• Sub-steps:
  1. Locate the wheel speed sensors at each wheel hub.
  2. Disconnect the electrical connector and remove the mounting bolt.
  3. Remove the sensor from its housing and inspect for damage or debris.
  4. If damaged, install a new ABS wheel speed sensor and torque the bolt to manufacturer specifications.
  5. Reconnect the electrical connector.

3. Check and Replace ABS Fuse/Relay

• Tools Required: Fuse puller, multimeter.
• Sub-steps:
  1. Locate the fuse box and identify the ABS fuse using the diagram.
  2. Remove the fuse and check for continuity with a multimeter.
  3. If blown, replace it with a fuse of the same amperage.
  4. Check the ABS relay in the fuse box; replace if necessary.

4. Brake Fluid Inspection and Replacement

• Tools Required: Brake fluid tester, wrench, bleed kit.
• Sub-steps:
  1. Remove the brake fluid reservoir cap and check fluid level and condition.
  2. If fluid is low, top off with manufacturer-recommended brake fluid (usually DOT 4).
  3. If fluid is contaminated, perform a brake fluid flush.
  4. Bleed the brake lines using a brake bleed kit to eliminate air.

5. Reconnect Battery

• Reconnect the negative terminal of the battery.
• Start the vehicle and check if the ABS light is still illuminated.
