It reads the internal EEPROM of the diagnostic cable to identify the specific ATmega chip type (most commonly ATMega162) and the firmware version loaded onto it.
To correctly identify your hardware version, follow these steps: This is a critical piece of information if
Plug your USB VCDS cable into the computer and to a 12V source (such as the car's OBDII port). Run the Utility: Run VAGCOM_HWType.exe . Read Hardware: Press the Read button.
VAG-COM is a popular tool among car enthusiasts and professional mechanics for diagnosing and troubleshooting issues in vehicles produced by the Volkswagen Group. It allows users to read fault codes, monitor vehicle systems, perform basic settings, and more.
It is primarily used by owners of older or third-party diagnostic cables to ensure they are using the correct drivers and software versions (like VCDS-Lite) for their specific hardware. Key Functions
: If the tool cannot find your cable, check your Device Manager to ensure the Virtual COM Port (VCP) is installed and configured correctly, typically between COM1 and COM4. Why Does It Matter?
