Seat Leon VCDS Codes: Unlocking Hidden Features

This guide provides a comprehensive list of VCDS codes for customizing your Seat Leon. These adaptations, compiled from user experiences and online resources, allow you to enable features not activated by default. Remember to perform an auto-scan and save your original coding before making any changes. We hold no responsibility for any issues that may arise. Always proceed with caution.

Essential First Steps: Auto-Scan

Before implementing any VCDS modifications, conducting an auto-scan is crucial. This process creates a backup of your car’s current settings, allowing you to revert to them if necessary. Here’s how:

1. Ensure your computer is powered on without VCDS running.

2. Connect the VCDS cable to your computer’s USB port.

3. Connect the other end of the cable to your car’s OBD-II port.

4. Turn your car’s ignition on.

5. Launch the VCDS software.

6. Click on “Auto-Scan.”

7. Once the scan completes, save the results with descriptive details. This file contains your original coding.

8. If any fault codes appear, click “Clear DTCs.” VCDS will automatically re-scan.

9. After saving and clearing faults, return to the VCDS home screen.

10. Click “Select Control Module.”

11. You are now ready to begin adaptations.
