Help to code MMI Screen down to stay down on engine start d4 s8

[d4s8]

Hello,

I have a 2015 s8 and I would like the MMI screen to stay down on engine startup. All other MMI functionality to stay the same.

Does anyone know the code to do this or where to start looking?

The interior has such a clean design I don't like the lines being ruined by a screen!

Thank you in advance

I want the MMI system to start but the screen not to raise. What bit will do this?

ChatGPT said:​

To have the MMI system start up while preventing the screen from raising automatically on a 2015 Audi S8 (D4), you will need to modify a specific setting in the 5F control module through VAG-COM (VCDS).
For your vehicle, the setting to control the screen's automatic raising (while still allowing the MMI to start) is typically found in Byte 18 of the 5F - Infotainment System module.
Here's the exact process to disable the screen from raising:

Steps:​

1. Connect your VAG-COM (VCDS) tool to the OBD-II port and open the VAG-COM software.
2. In the software, go to "Select Control Module".
3. Choose "5F - Information Electr." (Infotainment system).
4. Click on "Coding".
5. Open the "Long Coding Helper".
6. Locate Byte 18 in the list of available bytes.
7. Look for Bit 2in Byte 18 — this bit controls the automatic raising of the screen.
   • Bit 2 = 1: The screen will raise automatically when the MMI system starts.
   • Bit 2 = 0: The screen will not raise automatically when the MMI system starts, but the MMI itself will still turn on.
8. Change Bit 2 to 0 (this disables the automatic screen raising).
9. Save the coding and exit the Long Coding Helper.

Final Note:​

• After making this change, the MMI system will still power on automatically when the engine is started, but the screen will stay down, requiring you to manually raise it if desired.

As always, be sure to backup the original coding before making any changes, just in case you need to revert to the default settings.

Please post a complete VCDS Autoscan from the vehicle.

We'll need to see an Auto-Scan from this car in order to determine whether Chat GPT's answer is at all plausible.

Update.. I followed the GPT instructions and changed

Sure enough the MMI screen did not open on start up, however it now it does not close immediately when the car shuts off.

I've not experimented more than that. A janky work-around might be to make the screen shutdown timer to a super short time. But still looking for the optimal solution

You cant knock it - You got exactly what you asked for !!

For your vehicle, the setting to control the screen's automatic raising (while still allowing the MMI to start)

I think Byte 18 is the setting to control the screen's automatic raising automatic function - but you never know !!

What is it doing up in the first place ?? Clean lines and all that ?
