For Menu navigation, you can practice through the DEMO here:
http://www.ross-tech.com/vcds-lite/m...in_screen.html
Keep hitting the buttons and the demo will take you through most menus, as though it is connected to a car.

Just wanted to share my knowledge and experience on VCDS: CAN Gateway: CAN (Control Area Network) is a Network hub used to exchange serial data between various controllers and sensors. Difference between model-versions is mainly with respect to increase in communication speed and bandwidth (additional ports - so that more controllers can be connected). Some of the newer versions have an additional function of initiating a stored program, when interrupted by connected modules (example: DAS).
Control modules that are
physically installed, should be activated in the CAN Gateway
Installation list. To find out the list of control modules that are installed in the car, we can refer to the
CAR DATA sheet, as this is
VIN specific.
Once a module is activated in the Installation list, CAN Gateway will establish communicate with it. If the module is physically not installed, CAN Gateway will
not receive any feedback from the module and therefore, throws an error in the Auto-scan.
CAN Installation list should be altered
only if any control module is added or replaced. Just activating a module in this list will
not help and will only create problems!
There is nothing much to do with the Long coding and Adaptation, in the CAN Gateway. DAS can be activated under adaptation. Again, anything with CAN Gateway should be changed
only after proper deliberation!
Control Modules: IMHO, modules like Engine, Gearbox and Airbags are best left untouched!
Rest are relatively simple. If a feature is not supported by the module, it will not accept the new code. If the code is accepted and the corresponding sensors are not physically present, it will throw an error in the Auto-scan.
Often, multiple modules needs to be coded to activate a particular feature – For example; CAN Gateway and Instrument cluster needs to be coded to activate DAS. Here, sequence of coding is important. In my opinion, driver interface wherever applicable, needs to be coded / adapted
before the primary module. That is, in this case, Instrument panel needs to be adapted first
and then the CAN Gateway. This way, all supporting modules will be ready for use, by the time the primary module is coded / adapted.
Points to ponder:
Make sure that all electrical devices such as AC/Fan, Interior lighting, 12V power sockets are switched-off / un-used during the time VCDS is connected to the car. This will avoid battery drain. Sometimes, a single session can go on for more than a couple of hours and could result in a drained battery! It is also a good idea to keep time during the activity.
All window glasses can be lowered for ventilation. Some of the modules require the doors to be kept open, for VCDS to properly communicate and execute user inputs!
To begin with, please scan all modules and save the report as reference.
It is better to change / activate one function at a time and then run an auto-scan, just to see that there are no errors registered. This way, if the auto-scan throws an error, it is easier to go back and correct the same.
Each time we input a request, VCDS communicates with the respective module and will carry out the operation – VCDS is
not just software running in isolation! While navigating through menus,
allow the software to finish the task in hand.
DO NOT interrupt - This can cause communication problems!
It is best practice to always start and end the session with an Auto-Scan. Exit VCDS
only after you see a clear scan without
any error!
Hope this helps!
Take care!! All the best!!!
