How do I troubleshoot a faulty electrical system in my Audi A5?

I've been experiencing issues with my Audi A5's electrical system, specifically with the radio and headlights flickering. What steps can I take to diagnose and fix this issue?

First, check if your battery terminals are clean and securely connected. Loose or corroded terminals can cause electrical issues. If this does not resolve the problem, it could be a faulty alternator. It's best to have a trained mechanic check and replace it if necessary.

Another potential solution is to inspect your fuses. A blown fuse can disrupt the electrical flow and cause malfunctioning components. Refer to your owner's manual to locate and replace any blown fuses.
