1.0 VCDSAN INTRODUCTIONIf yourelike me, keen to want to take advantage of the optional extras that you can enable via
VAG-COM, but afraid that you might screw things up, here is an introduction and a simple task
that should help overcome your initial concerns.
Please note this is not an authorative document, purely a guide to help you get started. For some it
may appear overtly verbose, but is purely aimed at getting you through each step with to build your
initial knowledge and confidence.
So, before you start a few simple tips.
Having connected your cable to the car and using the VAG-COM software, the ignition
should be on. (The engine doesnt need to be running). Normally a good idea to turn off
your lightsset switch to 0.
Leave the MMI switched on as you will need to use the MMI screen to view the hidden
menu and such like.
When running tests it is normal for the car to flash up warnings like ESP Failure Warning
on the DIS, accompanied by various clicks as the car runs through these checks.
1a). VCDS Home screen
Pressing on the Select Control module button willpresent you with a display of all the control
modules available(see next screen)
1b). The modules are contained in a separate tab
format starting with Common through to
Electronics 2.
INFO: Thecommon tab changes name to
Installed, when connected to your car reflecting
the modules installed on your car.
If 09-Cent. Elect. is selected, you will be presented
with the controller info(see next screen)

1c). Changes are typically completed by selecting
the Coding 07button, you will be presented
with the re-code module (see next screen)
1d). Modules and Slave Modules (Drop Down
Menu).
INFO:If the module shown is greyed out, there are
no selectable slave modules.
On the latest cars, many "slave" modules are
codeable.
The coding screens (both regular and "long") will
present a drop-list of available modules which can
be selected for coding.
You have the option of writing the new coding in
here; however for ease of use it is strongly
recommendedthat the Long Code Helperis used
(see next screen)
1e). For ease of understanding a separate
explanation of each aspect of this screen is show
below

A RECOMMENDATION FROM A SEASONED PRO (NOT ME IMIGHT ADD!!!)
As you starting out dont get over confident using VCDS and ALWAYS, ALWAYS keep an eye on everything
you do regardless of how many times you have used it until you have become semi pro.
It is very easy to change something and you may end up with a dead MMIor rock hard steering just by a
simple change of a 0 or a 1. Then its either off to the dealers (along with some currency in your hand), or
requesting codes for comaprisons from fellow members along with the resulting headache.
KEEPING TRACK OF CHANGES
Before changing any setting, have a blank Word doc open and copy a screenshot beforechanging the
setting values. Therefore, if you have an error after changing the value you can always revert back to theoriginal setting.
(Ctrl + Alt + PrtSc) captures the uppermost open screen
(Ctrl + V) will paste it into the Word Doc.
Hold (Alt) button then press (tab) to swap between Word and VCDS
Finally good luck and be careful!
Remember to make notes and "backups" of any settings you change so that you can try to
go back if something goes wrong.
Please be aware that VAG-COM is potentially a dangerous tool, you can mess your car up.

2.0 Adjustable Footwell lighting:Task Difficulty Rating:
Okay, so here is a simple task (1/5) that will get you accessing bytes, changing bitvalues and
activating the hidden menu.
The mod enables you to adjust the footwell lighting on Audi A4 B8/A5 cars that do not have the
adjustment menu enabled as standard.
There are three stages to this, first is enabling the Ambiance lighting and second is activating the
hidden menu and lastly setting the lighting in the MMI to control the brightness.

FAQS
FAQs The lights stay on all the time the car is on when headlight is set to off.
It has been confirmed the lights will go on and off with the light sensor if the headlight
switch is set to Auto.
This does work on both the front and rear foot lights.
If you turn the lights all the way down the lights will go to full brightness when you open
the door. Master light switch will not control these lights at all anymore. They will work
separately through the MMI.
Lights will not go to 100% in Ambiance mode but will when door is opened.
