Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface.
  • Disconnect the battery to prevent any electrical issues.
2. Inspect and Clean ABS Wheel Speed Sensors
  • Locate the wheel speed sensors at each wheel hub.
  • Disconnect the electrical connectors from the sensors.
  • Clean any dirt or debris from the sensor and the mounting area.
  • Reconnect the sensors and ensure they are securely fastened.
3. Check and Replace Brake Fluid (if necessary)
  • Locate the brake fluid reservoir.
  • Check the fluid level and condition; if the fluid is dark or contaminated, it should be replaced.
  • Use DOT 4 brake fluid (as specified for Porsche vehicles).
  • Bleed the brake system to remove any air bubbles after replacing the fluid.
4. Inspect ABS Control Module
  • Locate the ABS control module, typically found near the brake master cylinder.
  • Check the electrical connections for tightness and any signs of corrosion.
  • If corrosion is found, clean the connectors with electrical contact cleaner.
5. Test ABS Pump and Relay
  • Locate the ABS pump relay in the fuse box.
  • Use a multimeter to check for continuity in the relay.
  • If the relay is faulty, replace it with a new one.
  • If the pump is not functioning, it may require replacement.
