While VWTool 2.0.9 is excellent for quick scans, it has limitations compared to paid VCDS software:
Inside the software:
Locate the file Audi-VWTool Version2.0.9 -Car Diagnostic Program-.exe from a trusted source (e.g., reputable VAG diagnostic forums). Warning: Many free download sites bundle malware—scan the file with antivirus software first.
Since this is an unofficial tool, installation is not as straightforward as a typical commercial product. Follow these steps carefully: Audi-VWTool Version2.0.9 -Car Diagnostic Program-.exe

Recommended setups:
Important: This tool does not support WiFi or Bluetooth OBD2 dongles (e.g., ELM327). It requires a direct USB-to-OBD hardwire connection.
