What are the common issues with the Audi A2's electrical system?

I've been having some problems with my Audi A2's electrical system. What are some common issues that I should look out for and how can I fix them?

One common issue with the Audi A2's electrical system is a faulty battery. It is important to regularly check your battery's voltage and replace if necessary. Another issue is with the alternator, which can cause all sorts of electrical problems if it is malfunctioning. My advice would be to have a professional mechanic check and replace the alternator if needed.
