Retrofit Volvo V60 B&W

[mupo]

It's reporting a DTC; go into the module to see the error and you'll know what's wrong.

Yellow means DTC Stored for that module.

Also, I don't see AUD module on top of the DTC Report.
Could red module means that module is faulty or no connection with it?

At the same time I don’t have issues with the sound system (or at least I don't see them) and everything is working correctly.
