I just recently purchased a 2019 s4 and for some reason the previous owner changed the Mmi startup screen to show a5 not s4. I have Ross tech vcds. Does anyone know the coding process for changing this back to the s4 splash screen?

Google doc referenced here has coding to change vehicle type

Thanks, somehow I missed this in that document. I notice it says for changing the virtual cockpit but not for the mmi screen. My virtual **** pit comes up as s4 but the mmi screen shows a5 on startup.

Maybe this one as well then, though it mentions Tegra MMI rather than Qualcomm one.

Thanks. I tried this and so far no luck. I am new to the long coding process so maybe I'm doing something wrong. If anyone with a b9 s4 is willing to share their 5F module coding on here for me to compare that would be much appreciated. I attached a photo of my mmi version.

Here is OBD11 coding for MMI splashscreen made by myself. Just enter 5F>Long coding>byte 18 and put your desired value. If using VCDS then this OBD11 value must be converted to HEX and change it in 5F>byte 18

I would be using ross tech VCDS. Here is my code currently I guess I'm a bit unsure of which is byte 18 that needs to be changed and dont know how to convert. any assistance would be appreciated?

Using the MMI sheet from above:

0E Hex = 14 Decimal = A5 Quattro
0A Hex = 10 Decimal = S4 Quattro

thank you so much!! Finally after a 1.5 years this is fixed!!! THANK YOU!
