Troubleshooting Guide: Audi Won’t Connect to VCDS

Step 1: Check the Basics

1. Ensure the OBD Port is Clean: The OBD port can accumulate dirt and debris, hindering a proper connection. Clean it gently with a small brush or compressed air.
2. Verify the Connection: Ensure the VCDS cable is securely plugged into both the OBD port and the computer. Try wiggling it slightly to ensure a firm connection.
3. Check the VCDS Software: Ensure you’re using the latest version of the software. Outdated software can cause compatibility issues. Download the latest version from the official VCDS website.
