How do I troubleshoot my Audi A5's electrical system?

I'm having issues with my A5's electrical system, specifically the radio and dashboard displays flickering. What steps can I take to diagnose and fix this problem?

First, check all the fuses related to the electrical system. Sometimes a simple blown fuse can cause issues with the displays. If the fuses are all fine, it could be an issue with the wiring or the displays themselves. It's best to take it to an authorized Audi dealership for further diagnosis and repair.

Try disconnecting the battery and letting it sit for a few minutes before reconnecting it. This can sometimes reset the electrical system and fix any glitches. If the problem persists, it's best to bring it to a professional for further inspection.

I had a similar issue with my A5 and it turned out to be a faulty ground connection. It's worth checking all the grounding points around the radio and dashboard to see if any of them are loose or corroded. That could be the culprit of the flickering displays.
