Hello guys, so first of all thank you for all the info regarding A9 and C0 sound modules information it was very helpful and educative :)
I have an Audi A7 4G platform that did not had the sound module or the sound actuators, so I decided to retrofit it, all god all nice, I made the harness, connected to CAN gateway(CAN High-drivetrain and CAN Low-drivetrain), activated the C0 in CAN installation list, everything worked perfectly, module is communicating ok, in the first phase I had the Wrong vehicle type error witch had been resolved by flashing FL_4G0907160B0007_UNLOCKED.odx file on it with ODIS, after flashing now I have these 2 errors:
0014 -Data Bus
-U1121 00 [009] Missing Message
0010 -Data Bus
-U1121 00 [009] Missing Message
Afterwards I flashed both
FL_4G0907160B0007.MODIFIED3.WORK.PERFECT.odx
and
FL_4G0907160B__0007.MODIFIED3.WORK.PERFECT-Benzin.odx
In both cases the sound module had no errors, the sound is present, it changes with acceleration, but it is very small/low/quiet even if the volume is set to100%, also another thing I've noticed is a background noise present like a small buzzing in the actuator high pitched from the moment i put the ignition on and also when the car is on.
I tried to do a test tone which worked had some UFO sounds :)) and it sounded quite ok and high [as volume]
What am I missing? Any thoughts would be highly appreciated, I got so far with this retrofit and got stuck at the end :(
