What is VAG-COM 409.1 KKL USB Cable?
VAG-COM 409.1 KKL USB cable is a device that plugs into the 16-pin OBDII socket of your vehicle and connects to your computer via a USB port. It works with the VCDS-Lite software, which is a free version of the popular VCDS software from Ross-Tech. The cable and the software allow you to access various diagnostic functions and data of your vehicle, such as reading and clearing fault codes, viewing live data, performing basic settings, coding, and more.
However, there are some limitations of the VAG-COM 409.1 KKL USB cable and the VCDS-Lite software. First of all, they only support vehicles that use the ISO9141-2 or ISO14230-4 (KWP2000) protocols, which are mostly older models up to year 2004. They do not work on vehicles that use the CAN-BUS protocol, which are newer models from year 2005 onwards. Secondly, the VCDS-Lite software is a free version that has some features disabled or restricted. For example, you can only scan up to 3 control modules at a time, you cannot save or print any data, and you cannot access some advanced functions. To unlock these features, you need to pay $97 to upgrade to the full version of VCDS software from Ross-Tech.
Therefore, if you have a newer vehicle that uses the CAN-BUS protocol, or if you want to access more features and functions of your vehicle, we recommend you to get the complete VAG-COM 2021 cable with original, unlocked and full version of VCDS software from Ross-Tech. This cable supports all protocols and models of VAG vehicles, and has no limitations on the software.
