How can I fix the charging issue in my Audi A2?

I have been experiencing a problem with my Audi A2 where it won't charge properly when connected to a charger. What could be causing this and how can I fix it?

Based on the information provided, it seems like the issue could be related to a faulty charging port. My advice would be to carefully inspect the port for any damage or debris, and if necessary, replace it.

Another possible cause for this issue could be a faulty battery. I would recommend getting it checked and replaced if needed. It's always better to have a professional do this for you.

Sometimes, charging issues can be caused by a software glitch. Try resetting your Audi's infotainment system and see if that resolves the issue.
