How to Use VCDS-Lite 1.2 13 to Diagnose Your Car




VCDS-Lite 1.2 13 is a software program that allows you to communicate with your car's on-board diagnostic system and access various modules and functions. It is compatible with older VAG cars (Volkswagen, Audi, Seat, Skoda) from 2005 or earlier that use K-line or KWP-1281 protocols. You can use it with any 3rd-party interface that supports these protocols, or with some of the old Ross-Tech interfaces.

Connecting Your Interface and Car




Before you can use VCDS-Lite 1.2 13, you need to connect an appropriate interface between your PC and your car.

You can find a list of compatible interfaces on the Ross-Tech website: https://www.ross-tech.com/vcds/download/.


The interface usually connects to your PC via a USB port or a serial port, and to your car via the OBD-II port under the dashboard. Make sure you have the correct drivers installed for your interface if it uses USB.


Once you have connected the interface, turn the car's ignition switch ON. No need to start the engine.

When you start VCDS-Lite 1.2 13 for the first time, you will see a screen like this:


Click on [Options] and select the correct communication port that your interface uses. You can use [Test] to confirm that the program can use the port and find the interface. Then [Save].


Now you are ready to play with VCDS-Lite 1.2 13. Make sure the software can reliably access all the control modules that it should in your car. You can see a list of supported modules and functions on the Ross-Tech website: https://www.ross-tech.com/vcds-lite/application-charts/.
