Common Issues with Audi A4 Audio System

I'm experiencing some issues with my Audi A4's audio system. How can I troubleshoot and fix these problems?

First, check the connections to make sure they are secure. If that doesn't work, try resetting the system by disconnecting the battery for a few minutes. If the problem still persists, it could be a faulty audio unit and will need to be replaced.

I had a similar issue with my A4's audio system and I found that there was a loose connection in the wiring. Double check all the connections and make sure they are secure.
