Here’s the real discussion initiated by users with VAS 5054A ODIS or/ and VAG VCDS.

* Bluetooth with VAS 5054, but not with VAG COM

That said, I do wish that Ross-Tech would introduce a Bluetooth-enabled scanner product! But even the clone vas5054 comes with Bluetooth, available within 2 to 5 meters. After a connection to the VAS 5054A has been set up, the Bluetooth software provides a virtual serial COM port (Bluetooth Serial Port Profile). The Diagnostic Base System uses this COM port to communicate with the VAS 5054A.

You need to specify this port when you install the diagnostic application.

* Operating system:

Vas odis- Windows 7, XP(xp2/xp3)

Vag- Windows XP, Windows 7 and Windows 8

* VAS PC by the manufacturer/China, while VAG COM by Ross teck

VAS PC is the manufacturer’s diagnostic system, and very populous by VAG owners even the China clone.

VAG com is a software created by Ross teck

Elsa is the system that allows the manufacturer to have technical documentation

and ETKA is the system that allows for the reference and saw broken pieces of a vehicle

* VAS is updated online, while only original VCDS can be updated online.

VAS is the builder interface (but the software is 2013) can be updated online

vcds or vagcom in clone can be updated online, but the only interface that can be updated online is original

* VAS coding must be online, while VAG not

The VAS / ODIS is the official tool for VW, the VAGCOM is a quality alternative to the VAS / ODIS, it is easier you can code some thing you can not with the VAS (because it must be Online), the VAS allows you to flash against by for update, but it’s a little plant has gas.

* China clone 5054a interface is enough for home use

If you have garage, car repair – you will need both. For home use, clone 5045a interface is enough. I have both because “there is no perfect interface for all job”. For example, Ross tech never calibrate RVC, even if you follow instruction, and all of my friend also couldn’t calibrate. For VAS is 5 min.

Cheap 5054a is simpler, clear, fast in use, but expert – Ross Tech not supply any special login / security code. Most of the time VAS no need this – VAS login to controller automatically, you don’t need to know Security Acces etc.

Some unit can be recode by Ross tech, this same unit to recorded in VAS need to be do online ;(

For special exchange controller, VAS is simple, can easy make copy of codding and all settings.
