Q7 (4M) Coding

[andyhud007]

All,

In an effort to start documenting what can be changed/altered/enabled/disabled on the new Q7 (4M), I am creating this post/thread to keep all the information in one single place. This post is a "sticky" so will remain at the top of the Q7 forum. I will then keep this post updated as more information is uncovered. Of course, anyone can contribute by replying to this thread and I'll do my best to add it to the first post so all the information is stored in one easy place at the top.

Background

Audi/Seat/VW and other cars have always had the ability to be interogated from a computer diagnostic level to see what is within the car. This is all done via the ODB II connector you will find under your footwell on the drivers side of your car. Its a purple connector (colour could be different) and by connecting a device to this along with a laptop (or nowadays even a mobile phone with an app) we are able to interface with the cars computer systems and see whats inside, whats configured and in some cases alter, change, enabled and disable things.

Some items are easy to change because they are the same across varying cars (like all Audi models for example) while other items are much harder to change/alter because they are (for example) stored behind security access which requires getting past. Even then, some items are not available because to alter them they require "calling home" to Audi HQ to make the changes.

That all being said, there is a lot available to look into and that is what this thread will attempt to detail.

Q7 (4M)

The new S/Q7 (4M) is one of the first cars from Audi to utilise a newer platform they call MLB 2 (somtimes refered to as 'MLBEvo') Do a search for these terms online to read more about them.

The downside to this is the new Q7 (4M) utilises the new MLB2 platform, and so a lot of the information around changes that were uncovered under the older MLB platform (common across many Audi's/VWs etc) do not apply to this new platform. We are effectively starting from scratch again to uncover what may be possible and sadly this just takes time.

In addition, the systems used to connect to the platform, in some cases themselves require updates/changes to be able to interface with the car. As you can imagine, this also takes time as those vendors start to peel back the layers of the MLB2 platform and learn how to interrogate it.

On the plus side, there are many enthusiasts, such as myself keen to understand and break these barriers down and I have been talking a number of folk across the world to see what is possible and we are slowly making progress.

Devices

There are many devices you can purchase online to connect to your car. Anyone can purchase these and you dont need to be a car dealer/mechanic to get hold of them. However some of them can be very powerful and if you dont know what your doing you could end up with a car that wont start/lock/turnover or whatever else. This would involve getting it to a dealer to effectively be "factory reset" which no doubt will come at a price!

I have only worked with 2 devices and I do not work for either of these companies but over the last 6 years of using them I find them good for my needs. There are other products available but I have no experience of any other products so unfortunately can't comment on them. Some may be able to do the same/more/less.

The two I use are called VCDS (Vag Com Diagnostic System) and VCP (Vag Com Pro). A quick search online and you can find out about these, their cost and how to use them.

Update 2/11/2016: I am now starting to include ODBEleven device coding changes for those of you that have an ODBEleven device. Will add as we uncover them.

Coding / Adaption Changes

Below I will start to detail what changes can be made that we have uncovered so far.

1. These are nearly all for the Q7 4M ONLY.
2. *** Ensure you create a backup of your car before making any changes. In VCDS for example, do a complete "Auto Scan" and let it finish before carrying out any coding. Save the output (txt file) to your computer. ***
3. If something doesn't work as expected go straight back to the change you made and revert it to avoid losing track of what you altered.
4. The changes below will have been done by either VCDS (with a Hex-NET Interface) and/or VCP or in some cases ODBEleven. I'll detail which system for each one. It may be possible other devices can use the same steps.
5. I accept no responsibility for any damage this may cause to your car. I detail the below to the best of my knowledge and as safely as possible. Follow the steps and you should be fine. If your unsure, ask.

Useful Helpers

MMI Reboot

Sometimes the changes require the MMI to be rebooted (like a 3 finger salute on a computer) for changes to show up/take effect. Switching the ignition off/on isnt enough

In the Q7 (4M) a 3 Finger salute is done by holding the Nav and Radio Buttons "up" and then pressing the main rotary knob. This will cause the MMI to do a quick reboot.

Note: Yes, you can do this while driving.
