Poor radio reception

[audifin]

Thanks Snapdragon. At least in my previous car (Honda) I was able to read and clear air conditioning fault codes with this same module, but I shall investigate further. Maybe I need to buy proper VCDS kit.

I removed the trim above rear window today and there it was...

If the amplifier is broken, will that create a fault code or is there any other way to test it? I couldn't find anything amp related by A8L Chick...
