Hello. Thanks for your work, I used your firmware and I have one problem, I don’t know how to solve it yet, I’ll try to describe it.

  1. What I have, Audi A6 C7 2.0 petrol
  2. Active Exhaust Unit flashed in FL_4G0907160B__0007_UNLOCKED.odx
  3. I have no errors that the wrong car etc.

I have 2 errors

0000A [10] U112100 Databus missing message (Keine Funktion durch CAN FehlerMotorsteuergeratebotschaft fehlt-_ keine Klangerzeugung)

0000E [14] U112100 Databus missing message (Keine Funktion durch CAN FehlerESPsteuergerätebotschaft fehlt-_-> keine Klangerzeugung)

I got exactly the same errors when I installed Sound Actuator and flashed it to FL_8S0907159__0004.TTRS.MOD1.odx I was very upset at that moment that I made a mistake somewhere, but then I flashed into FL_4G0907159B__0010_UNLOCKED.odx and everything worked perfectly for me, the errors were gone, from which I concluded that these firmwares had some kind of different core and that TTRS does not work on A6 C7.

It may be that the firmware FL_4G0907160B0007_UNLOCKED.odx FL_565907160A0005_UNLOCKED.odx FL_8W0907160___0001_UNLOCKED.odx a common core was used, in which there is a parameter to use some other CAN Databus, which does not work on A6 C7?

Oh, it’s a pity that you won’t be able to try all the firmware options, you probably have to buy a Kufatec unit for better sound. In general, I managed to get the exhaust to work, I found it in this thread a similar problem, https://github.com/jilleb/m... I found the firmware there: https://github.com/jilleb/m...

I think for the first time this is enough for me to play around, then I will wait for Kufatec and deal with exhaust welding. Maybe I'll try to deal with the 010 editor and edit other files for the MLB platform :(

Im having the same errors with FL_4G0907160B__0007_UNLOCKED.odx Tried what you wrote as a solution earlier and:

Flashed FL_4G0907160B__0007.MODIFIED3.WORK.PERFECT-Benzin.odx, no errors, I have sound, it responds to the acceleration throttle but is very very low volumed, any thoughts? Highly appreciated any feedback

Car is an Audi A7 4G platform, 3.0 TDI V6, and did not had the option, I retrofitted the harness and the original sound module, if it matters
