Troubleshooting Common Issues

Encountered an issue while using VCDS? Here are some common problems and potential solutions:

• “No Response from Controller” Error: This usually indicates a communication problem. Check your cable connections, ensure the ignition is on, and try a different USB port on your laptop.
