Vcds Lite 1.2 Full 25l
What is Vcds Lite
Vcds Lite is a continuation of the development of VAG-COM, which was the original name of the diagnostic software for Volkswagen Group cars. VAG-COM was developed by Ross-Tech LLC, a company that specializes in automotive electronics. VAG-COM was first released in 1996 and was updated until 2004, when it was renamed to Vcds (VAG-COM Diagnostic System).
Vcds Lite is a version of Vcds that works with older versions of VAG-COM interfaces, as well as some third-party interfaces that are compatible with the K-Line protocol. The K-Line protocol is a communication standard that was used by most Volkswagen Group cars until 2004, when it was replaced by the CAN-Bus protocol. The CAN-Bus protocol is faster and more reliable, but it requires a different type of interface.
Vcds Lite has some advantages over the older versions of VAG-COM, such as:
It works without any problems on Windows 7 and Windows 8.
It also supports 64-bit operating systems.
The interface has been improved and made more convenient.
It has more features and functions than VAG-COM 311 and 409, which were the last versions of VAG-COM.

What is the difference between Vcds Lite and Vcds
Vcds Lite is a simplified version of Vcds that works with older cars and interfaces. Vcds is the full version of the diagnostic software that works with newer cars and interfaces. There are some differences between Vcds Lite and Vcds that you should be aware of before using them. Here are some of the main differences:
Comparison of features and functions
Vcds Lite has fewer features and functions than Vcds. Some of the features and functions that are not available in Vcds Lite are:
Advanced measuring values, such as graphs, gauges, min/max values, etc.
Long coding helper, which assists you in coding new or replacement control modules.
Label files, which provide detailed information about each control module and its parameters.
Auto-Scan, which scans all the control modules in your car and generates a report with fault codes and other information.
Service reminder reset, which allows you to reset the service interval indicator on your dashboard.
SRI reset, which allows you to reset the airbag warning light after replacing or repairing the airbag system.
OBD-II generic scan tool, which allows you to access generic OBD-II functions such as readiness codes, freeze frame data, etc.
Vcds Lite also has some limitations in terms of functionality. For example, it can only access up to 32 control modules, while Vcds can access up to 255. It can also only display up to 12 measuring values at a time, while Vcds can display up to 64. It can also only log up to 3 measuring values at a time, while Vcds can log up to 16.
Compatibility and requirements
Vcds Lite is compatible with older cars that use the K-Line protocol, as well as some third-party interfaces that support this protocol. However, it is not compatible with newer cars that use the CAN-Bus protocol, or with Ross-Tech's HEX series interfaces that support this protocol. If you have a newer car or a HEX interface, you need to use Vcds instead of Vcds Lite.
Vcds Lite requires a Windows PC with at least 1 GB of RAM and 100 MB of free disk space. It also requires a USB port or a serial port to connect the interface. It works with Windows XP, Vista, 7, 8, and 10. It does not work with Mac OS or Linux.
Pricing and registration
Vcds Lite is free to download and use for non-commercial purposes. However, it has some restrictions in terms of functionality until you register it. To register Vcds Lite, you need to pay a one-time fee of $99 USD. This will unlock all the features and functions of Vcds Lite for one interface. You can register multiple interfaces if you have more than one.
Vcds is not free to download or use. You need to buy a licensed interface from Ross-Tech or one of their authorized distributors. The price of a licensed interface depends on the type and model of the interface. For example, a HEX-V2 interface costs $199 USD for 3 VINs (vehicle identification numbers), $349 USD for 10 VINs, or $599 USD for unlimited VINs. A VIN is a unique code that identifies each car. You can only use a licensed interface with a limited number of cars depending on how many VINs it supports.
How to use Vcds Lite to diagnose and repair your car
Now that you know what Vcds Lite is and how it differs from Vcds, you might be wondering how to use it to diagnose and repair your car. In this section, we will show you some of the basic steps and procedures that you can follow to check and fix your car problems using Vcds Lite.
Connecting the interface and the car
The first step to use Vcds Lite is to connect the interface and the car. The interface is the device that connects your computer and your car. It can be a USB or a serial interface, depending on the model. The car has a diagnostic port, usually located under the dashboard, where you can plug the interface.
To connect the interface and the car, you need to do the following:
