Why is the halogen headlight on my Audi A2 not working properly?

I recently noticed that the halogen headlight on my Audi A2 is flickering and sometimes doesn't turn on at all. What could be causing this issue and how can I fix it?

From my experience, this could be due to a faulty wiring or connection issue between the headlight and the car's electrical system. I recommend checking and cleaning the connectors and wires to see if that resolves the issue.

One possible cause could be a failing headlight bulb. Make sure to check the bulb and replace it if necessary. It's always a good idea to have spare bulbs on hand for any future issues as well.
