hey mates,


i have a Audi S6 US Import and some functions not available.
I guess somebody tryd to update MMI but wrong Firmware (TEL button opens Car Menu, some pictures are missing etc).

I cant enter in Hidden Menu.. tried every combination with TEL and MENU but nothing happens.. i did in 5F hidden menu activation.
Is it possible to reflash with ODIS-E or VCP?
Do i need to convert to EU or just do SVM Code and every works again?

Anybody have a Idea to make it work again?

Steering Wheel Button doesnt works to, just wheel heating.

Actually Firmware: HN+_EU_AU3G_K0942_3, Navi Version is empty.

thanks.

So you installed A4 software to A6 unit ...
Need to fix that back.

Soldering or jtag can't be done here. I also have a device from q7 4l mmi 3g where they threw the wrong firmware, it seems from 3g plus

Nah, you can do solder and jtag but why?
All is fixable w/o solder.

[VasyaUA]

Can you provide instructions or help remotely?

what you need to do is to install the right software for the model
to do that enable gem and then enable ignore region and variant and user defined
to enter gem you need to find the irght combination - as keyboard is not right now but it will work
or modify meta and add
EnableUserDefinedSWDLMode = "true"
skipMetaChecksum = "true"
skipChecksum = "true"
skipCRC = "true"
skipCheckRegion = "true"
skipCheckVariant = "true"
