How to fix malfunctioning headlights on Audi A1?

I've been having issues with my Audi A1's headlights not turning on or flickering. What could be causing this and how can I fix it?

First, check the headlight fuse and replace if necessary. If the fuse is intact, then the issue may be with the headlight bulb. Consider replacing it, making sure to follow the correct installation procedure to prevent future issues.

Another possible cause could be a faulty headlight switch. Check for any damage or corrosion on the switch and replace if needed. Additionally, cleaning the contacts on the switch may also help resolve the issue.
