Hello Congo,
I hope you're doing well.
I recently bought a 2017 Audi A3 8V, and I’m experiencing an issue with the MMI (MHS2_ER_AU_P1240). I can connect my phone via Bluetooth and play music without any problems, but I cannot use the hands-free feature or read messages. It worked for one day, but since then, I haven't been able to get it working again. I’ve already tried a factory reset, but it didn’t help.
After some research, I found out that a firmware update to MHS2_ER_AU_P2035 might solve this issue. I don’t really care about navigation maps, and I have no intention of activating Android Auto or Wireless CarPlay, since my car only has a USB charging-only port in the armrest.
I’m not very familiar with cars and MMI systems, but I do have extensive knowledge of Linux and Unix-based systems, so I believe I can handle the update process with the right guidance.
I’d like to ask:
  1. Could updating from MHS2_ER_AU_P1240 to MHS2_ER_AU_P2035 fix my Bluetooth hands-free issue?
  2. Do I need to use any kind of activation method for this update, or can I simply copy the firmware to an SD card and install it from the Red Engineering Menu?
Thank you very much for your time and help!
 
Good morning,

First of all, thank you for your quick response Alex-07.
I'm having a little trouble understanding your last sentence.

Why install the congo activator after updating the firmware?

is this really necessary?

THANKS.
 
its needed if you have not the 2024 maps today working or the other FEC´s arent activated/legal,
I mean if you dont need all FEC activated/legal, then no activator installation needed,
nothing else I mean.
Thank you for your details and the quick response, it's really appreciated.

I'm simply going to test a firmware update as you mentioned to me without installing the Congo activator afterwards because I don't need the 2024 cards to modify anything.

I just hope this solves my bluetooth problem. Which is quite curious.

I will come back here to say if this solved my problem or not.

Have a nice day thank you
