1) Missing the ground or ground and positive are not the same channel.
2) AUD did not boot up correctly.
Put the 028 RADIO, AMP AND SPEAKER SYSTEM to 04. Lock the car wait couple minutes and then check it. If that does not work, try to reboot the AUD from the ECU tools TAB.
Same thing happened to me couple of times, as if the amplifier is turned off.
I connect one cable to the upper connector and the other to the lower one. channel 2. I also tried to switch them. because I don't understand what grounding you mean.
