E55 amg 2003 I have and I’m having a issue to where I can’t get my plates. I have a p0600 code serial communication link and can’t figure it out. The battery was charged and they said it was good. It’s not draining or anything. Has anyone had this code before and got it fixed? Plz send me in the right direction this is nerve wrecking

Most common culprit on the 211 is the audio gateway module. Check battery voltage before and after you pull fuse #6.

thanks for replying .... I bought this car as is and it has an aftermarket touchscreen android with the canbus and axxess box. Speaker wires From the radio are run to the back of car professional installed. It has the Harman speakers in the door. There is no factory amplifier in the trunk. The audio on the dash says off. The sound doesn’t work only power on the android screen. The seats don’t work. Only lumbar make a air noise then stops. The fuse #6 audio gateway is good.
