    This guide has been written to show you which feaures can be changed/added on the Mk2 Leon. This includes:

    Turning off seatbelt warning
    Making the car beep when you lock/unlock
    Changing the steering weight
    plus much more


    The first section is for beginners who have never attempted this before. skip to the end if you want a list of coding options.

    Introduction

    VAG-COM is an amazing tool, more so with the latest generation of ECU's.

    There is so much that can be done with this piece of software:
    Checking and clearing fault codes.
    monitoring and logging hundreds of sensors inside the car.
    Recoding and chaging features of the car.
    Finding out other information from your car.

    To Begin, you will need the appropriate cable.
    The cables avalible are listed here: http://www.ross-tech.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=VAGCOM

    The Mk2 Leon (and all MkV golf platform based cars) use the newer CAN-BUS diagnostic interface. So ensure it is a CAN-BUS compatible cable.
    I personally use the Micro-CAN interface, as it is the cheapest one, but it will not work with the older cars such as the Leon Mk1.

    Ok lets get started. This guide will concentrate on how to change features within the car.


    Start VAG-COM

    (Click images for larger version)

    Click on the Select Control Module button:
    [​IMG]

    You then need to select which control module you want to go into. once you enter the control mdule you will be presented with the follow screen:
    [​IMG]

    Depending on what is required, there are two functions we will use:
    Coding and Adaption


    Coding:

    There are two types: Coding and Long Coding. This is depends which module you are coding.

    Lets start with changing something in a Coding Screen.
    [​IMG]

    First click on the "Coding - 07" button in your chosen module.In the above example, we are in Instrument Cluster.

    The coding screen comes up. The only field that we are interested in is the 'Software Coding' text field. The numbers in here are the settings for the chosen compoment. On most modules, once you open this Coding screen, a comment will appear with the instructions (as per the screen shot)

    In the example above, we are going to turn OFF the seatbelt warning.
    As instructed in the text comment, we need to change the 3rd and 4th number in the string. By default it would be 02, but we need to change it to 00 to turn it off.
    Once this is done, simply click the 'Do It!' Button and thats it.

    Next will will try Long Coding.

    As above click on the 'Coding - 07' button.

    The Recode mdule will open, then click the Long Coding helper button.

    You will then be presented with a long coding screen:
    [​IMG]

    Column 3) Is basically each page of items to change

    Column 4) Lists each bit (item) you can change on that 'page'

    In this example we will turn off The Coming Home feature.

    This is located in Byte 0 (81 as shown in column 3) on bit 7.
    If the feature is turned on, there will be a tick, if it is off, there will be no tick.

    So, to turn it off, untick bit 7.
    Then press the Transfer Coding button. This will then take you back to the recode screen. (below)

    [​IMG]

    The new code which you have just created, will be present in the New coding: Text field. Click 'Do It!' Button to make the changes. VAG-COM will comfirm to you if it has worked and accepted the coding.


    Adaptation:

    Adaptation is similar to coding, but can also be used to change variable values, such as steering weight and volume settings.

    [​IMG]

    This is pretty straight forward:
    Pressing read, it shows you the values in the top fields.
    Press the up/down button next to that, scrolls through the different channels (each channel has a different setting or none)

    Like the coding module, many channels will show a text comment with instructions, showing accptable New values. For example, On the Park Assist module, you can change the rear beeper volume. The default level was 60, but I wanted to turn it down to 50 level. The text comment told me this was possible.
    When you have changed the valve, press Test, then Save. and that is it.


    List Of Changable Options

    **These are acording to my '2006 Sport', the controller module versions may differ in newer cars so may not work as below.**

    One Touch Indicators (Comfort Indicators)
    This turns on or off the one touch lane indicator which gives you three indicator blinks on a sungle touch. This is on by default.

    Module 09 - Cent. Elects.
    Coding
    Byte 2
    Bit 8 - Comfort turn Signals


    Leaving Home Lights
    This feature turns on your lights when you unlock the car (if your headlight switch is on). I believe this option is standard if you have the auto lights option. This also adds an option in the MFD lights menu for how long it will stay on.

    Module 09 - Cent. Elects.
    Coding
    Byte 0
    Bit 5 - Assistance Driving Light_Leaving Home active


    Coming Home Lights
    This turns on or off the feature, where it leaves you lights for a short period on after you get out the car. This can also be changed via the larrger MFD if you have it.

    Module 09 - Cent. Elects.
    Coding
    Byte 0
    Bit 7 - Coming home active


    Coming Home Lights Active Time
    This sets how long the comning home lights styay on for. This can also be set through the larger MFD if you have the bluetooth option.

    Module 09 - Cent. Elects.
    Adaptation
    Ch.01
    Set a value between 10 and 60 seconds, must be in 10s.


    Emergency Brake Flash
    Im am not sure this features works, I have the option, but does not seem to activate on mine, may be a model year dependant feature.

    Module 09 - Cent. Elects.
    Coding
    Byte 17
    Bit 0 - emergency brake flash light active


    Turning Off Sealt Belt Warning


    Module 17 - Intruments
    Coding
    Change 3rd and 4th number in string to 00 as per text comment, or add up the number for the options you have, ie; you have headlight washers if you have xenons, so add that to the value.


    Selective Central Locking (single door opening)
    By default, when you press the keyfob to unlock the car, it only opens the drivers door with a single click. If you turn this features off, it will unlock all doors with a single click.

    Module 46 - Central Conv.
    Coding
    Byte 0
    Bit 0 - Selective Central Locking


    Automatic Window Closing/Opening
    This enables all the windows to close or open if you hold down the lock/unlock button on the keyfob, and or holding closed/open the keylock on the door
    I have found on newer cars (MY07?) these features are already active, but on my MY0 I had to activate it.

    Module 46 - Central Conv.
    Coding
    Byte 4
    bit 0 - Comfort opening power windows via door lock active
    bit 2 - Comfort opening power windows via remote control active
    bit 3 - Comfort closing power windows via door lock active
    bit 5 - Comfort closing power windows via remote control active


    Beep when locking/unlocking car (My favourite feature)
    This adds a beep when locking the car, and two beeps when unlocknig the car.
    Below; horn refers to the beep, and blink refers to the indicators blinking

    Module 46 - Central Conv.
    Coding
    Byte 6
    bit 0 unlocking confirmation (blink) via door locks
    bit 1 - unlocking confirmation (horn) via door locks - (makes 2 beeps)
    bit 2 - unlocking confirmation (blink)via remote control
    bit 3- unlocking confirmation (horn) via remote control - (makes two beeps)

    Byte 7
    bit 0 locking confirmation (blink) via door locks
    bit 1 - locking confirmation (horn) via door locks - (makes 1 beep)
    bit 2 - locking confirmation (blink)via remote control
    bit 3- locking confirmation (horn) via remote control - (makes 1 beep)


    Syncronised Mirror Adjustment
    Syncronised mirror adjustment, is the feature that automatically moves the left mirror when adjusting the right mirror. This is on by default.

    Module 46 - Central Conv.
    Coding
    Byte 9
    bit 6 - Synchronised mirror adjustment


    Anti Hijack
    This locks all doors when the car moves above 15km/h. This is on by default.

    Module - Central Conv.
    Adaption
    Ch.0
    1=on 0=off.


    Steering Weight
    Module 44 - Steering Adjust
    Adaptation
    Ch.01
    Select a value between 1 and 6 for weight.

    Volume of Reversing Sensor beep
    Module 76 - Park Assist
    Adaptation
    Ch.01
    Select value between 0 and 100. Default 60


    Changing Bluetooth Pass Code
    Module 77 -Telephone
    Adaptation
    Ch.15
    Choose a 4 digit value.

    Notes:

    The washer fluid level light will not work unless you have Xenons or headlight washers, so no need to enable it otherwise, as the car will not have a fluid sensor fitted.

    Thats it, let me know if you know of any others and I will add it to the list.

    Top post - really useful info.

    Is this data likely to be the same on the S3.

    I asked the dealer to use VAG.com to change the steering weighting and he looked at me if I was from another planet.

    Also want the mirrors to work together. S3 doesn't do this. Found it useful on the LCR as if I was parking in a space that was delimited between two high curbs you could tilt both mirrors down together.

    THere isn't one to make the mirrors fold in automatically when you lock the car is there?

    cheers

    Hi Warren, Most of things thing will probably be common, they are on the golf and the octavia etc. Best thing is to have a look and play really, cant see any damage being done if you tick the wrong option...

    I think the folding mirror option is possible on later cars if you hold the lock button down on the key fob, as per the window closing.

    If you look at the title of the thread, it says Mk2 Leon, you have a Mk1 Leon.

    Well done dan.. Took me a while to understand how the values worked for deselecting seatbelt warning without affecting the other options.. Binary! Doh blonde moment :D

    I only worked it out when i read the note in the seatbelt code section
    Brilliant post.. I think Vag-com is going on my shopping list and I think this post will become a great resource as people find more things out.

    In 2 minds about the one touch indicators.. they can be a curse and a godsend at the same time :)

    I may be adding something which has already been said before but I have just turned this on, on my 06 Leon Sport and also had to modify the following.

    Module 46 - Central Conv
    Coding
    Byte 3
    Bit 5 - Comfort functions via remote are inactive.

    I had to untick this to get it all to work.. took me ages to find! :blink:

    DanGB - not sure if you are altering this guide but thought you may like to include the above

    Cheers

    Hello mate havn't got vag-com yet, so I took my 06' 140 tdi to the dealers as total closure only works on key not the remote and was told this is only available on the 07' on wards. Can I confirm, you say you've done it on your 06 (they said not enough byte's to alter only 8)?
    Cheers Craig
