Thanks asm777. Do you think I need to keep Byte 8 Bit 4 on?

So I have my setting as:

MMI Hidden Menu
[car] [cardevicelist] -> check "charisma"
[car] [carmenuoperation] -> change "charisma" from 0 to 5
Reset MMI - Setup/Scroll Wheel/Top Right

[Coding - 07] -> [Long Coding Helper] -> Byte 7 -> Bit 5 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 1 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 2 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 4 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 17 -> Bit 7 change 0 to 1

[Security Access - 16] [Adaptation - 10] -> Channel 63 -> Change to 4
[Security Access - 16] [Adaptation - 10] -> Channel 64 -> Change to 4
[Security Access - 16] [Adaptation - 10] -> Channel 65 -> Change to 4
[Security Access - 16] [Adaptation - 10] -> Channel 66 -> Change to 4

Well, I don't know if it works only with 3.2 V6 engine because I tried everything on the post, I get the ADS item to show up, only to have it greyed out if I turn on the ignition/engine.

So I adjusted it back.

Also in the long coding section, I don't even have any options in byte 8 and 17 for ADS. I tried do direct binary edit but still to avail.

Does anybody with 2.0T were able to get it to work?

The first time I tried the coding my menu was greyed out also. I went through it all again and found i had missed one of the bits. I don't know about the 2.0

or,

[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 2 change 0 to 1
This is exactly what I did (below). However, I will also test bit 1 and see if I notice a difference.

[09 - Cent Elect.] VCDS coding of Audi Drive Select

[Coding - 07] -> [Long Coding Helper] -> Byte 7 -> Bit 5 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 2 change 0 to 1 (Display Engine in MMI)
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 4 change 0 to 1 (Display Steering in MMI)
[Coding - 07] -> [Long Coding Helper] -> Byte 17 -> Bit 7 change 0 to 1 (enable MMI display)


tortuga - Did you read the Audi Enthusiasts detailed write up at the below link? I believe it may answer your questions as well, here's the link again:

http://audienthusiasts.com/Project_ADS.html

Paste from there:
Byte 8 Bit 0 Change 0 to 1 - Enable Engine/Gearbox (This bit enables thorttle response control)
Byte 8 Bit 1 Change 0 to 1 - Enable Steering (This bit enables steering reponse control)
Byte 8 Bit 2 Change 0 to 1 - Enable Engine On MMI Menu (If equiped)
Byte 8 Bit 4 Change 0 to 1 - Enable Steering On MMI Menu (If equiped)

09-Central electric:
[Long Coding] Byte 7, bit 2, change 0 to 1 (this appears to be optional as no effect has beed determined to date as to why this should be enabled)
[Long Coding] Byte 7, bit 5, change 0 to 1

What you set for the next 4 screens will be dependant on your project. If you have ADS already or have a non MMI car you will set the ADS to what ever you want the default settings to be. In most cases I am assuming you will want Dynamic and will be setting the value in the "New Value" field to 3. If you have an MMI car you will be setting this to 4 as you can alter the settings directly in the MMI. Enter your new value and click save.
1 = Comfort
2 = Auto (Factory default)
3 = Dynamic
4 = Individual

Have a look through this thread.

I believe there are numerous folks that have done this on non-MMI (non-nav) Q5's and A4's without issue.

Good Luck!

Well I tried again this morning, still no go.

I can get the menu to show up but as soon as I turn on the ignition or engine the menu simply grays out.

I have a feeling ADS doesn't exist on 2.0T models.

Oh well, back to normal.

Finally got a chance to test out the ADS with MMI. I definitely feel the stiffness on the steering when in the dynamic mode but not sure if I notice any difference on the engine/gear box when in the dynamic.

Here is my current settings:

MMI Hidden Menu
[car] [cardevicelist] -> check "charisma"
[car] [carmenuoperation] -> change "charisma" from 0 to 5
Reset MMI - Setup/Scroll Wheel/Top Right

[Coding - 07] -> [Long Coding Helper] -> Byte 7 -> Bit 5 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 1 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 2 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 8 -> Bit 4 change 0 to 1
[Coding - 07] -> [Long Coding Helper] -> Byte 17 -> Bit 7 change 0 to 1

[Security Access - 16] [Adaptation - 10] -> Channel 63 -> Change to 4
[Security Access - 16] [Adaptation - 10] -> Channel 64 -> Change to 4
[Security Access - 16] [Adaptation - 10] -> Channel 65 -> Change to 4
[Security Access - 16] [Adaptation - 10] -> Channel 66 -> Change to 4

Bits 1 and 4 are for two different types of steering. You can likely turn off bit 4 as it doesn't do anything.

Are you seeing two options on your MMI screen (steering and engine/transmission) or three?

Currently, I see 2 options on the MMI, Engine / gearbox and Steering.

I haven't got a chance to turn off Byte 8 - Bit 1 but I think you're right since I didn't turn on Byte 7 - Bit 4 (dynamic steering installed), plus I know for sure I don't have dynamic steering installed.
