7.1 What is VCDS-Mobile?
VCDS-Mobile is diagnostic software for VW-Audi Group cars running in the
VCDS Mobile includes a web server in the interface and can be used with any device that has WiFi and a modern web browser. VCDS-Mobile is not an "app"
that runs on your mobile device.
7.2 What do I need to use VCDS-Mobile?
You will need a HEX-NET Interface.
You will need some sort of computing device that can communicate via WiFi and has a reasonably
modern web browser. This can be a smart phone (iPhone, Android, Blackberry 10, Windows Phone, etc);
it can be a tablet (iPad, Android, Windows RT tablet, etc); or it can be a laptop or desktop computer
running Linux, MacOS, or even Windows. ;-)
7.3 Is VCDS-Mobile easy to use?
Well, that depends. Unlike VCDS running on a Windows PC with a wired interface,
using VCDS-Mobile requires some rudimentary knowledge of networking to get the HEX-NET interface
communicating with whatever device you're using as well a finding it a way to access the the internet
so it can communicate with the VCDS-Cloud server. However if you get past that hurdle and you've
used VCDS, you'll find VCDS-Mobile to have a familiar look and and feel, and it should be just
about as easy to use as VCDS is.
7.4 What can VCDS-Mobile do?
Well, that depends. VCDS-Mobile has two modes of operation, Stand-Alone and Cloud-Connected.
In Stand-Alone mode, VCDS-Mobile can do Auto-Scans, read and clear fault codes, look at measuring values,
and log data. If it can communicate with the VCDS-Cloud server (and it's associated with an account on the server),
it gains additional functionality and is able to do Adaptations, Basic Settings, Coding, Login/Security-Access, and so on.
Please understand that at the time of this writing VCDS-Mobile is a
and we may have overlooked something.
7.5 Why won't VCDS-Mobile won't me show fault code text or measuring values?
On control modules that use the latest UDS/ODX protocol, it's not possible to
interpret fault codes or show any meaningful measuring value data
without a 'data dictionary' file specific to the control module in
question. VCDS-Mobile will get download these from the Cloud server on an as-needed basis. Once
it has downloaded the data for a specific module, that data will be cached (stored on-board) and will remain
available even when VCDS-Mobile does not have a connection to the Cloud server.
The best way to ensure that VCDS-Mobile has the data available for the
control modules in your car(s) is to do a complete Auto-Scan on any
car(s) that you will be using VCDS-Mobile on, then manually check for
7.6 How do I register my HEX-NET with the Cloud Server?
Right now, the only way to do that is to plug the HEX-NET into a car, access a control module in the car, click [Functions]
and then [Cloud Functions]. If your interface is not yet associated with a Cloud account, the server will
redirect you to a registration page, where you can either create a new account for it, or associate it with
an existing account. The HEX-NET must be able to communicate with our server, i.e. it must have
internet access when you do this.
