How can I troubleshoot the Audi A2's electrical issues?

I am experiencing intermittent electrical problems with my Audi A2. Sometimes, the lights will flicker or the power windows won't work. Other times, everything seems to be functioning perfectly. Is there a recurring issue with Audi A2's electrical system and how can I address it?

The most common cause of intermittent electrical issues in the Audi A2 is a faulty battery. Have your battery checked and replaced if necessary. Additionally, check all the wiring connections and make sure they are secure.

Another possible cause is a faulty alternator. A failed alternator can cause electrical components to not receive enough power, resulting in intermittent issues. Have your alternator checked and replaced if needed.
