What causes the headlights in my Audi A4 to flicker?

I've noticed that the headlights on my Audi A4 have been flickering lately. What could be causing this issue?

The most common cause of flickering headlights is a worn out alternator. It could also be an issue with the battery or a loose connection.

I had the same issue with my Audi A4 and it turned out to be a faulty voltage regulator. I would recommend getting it checked out by a mechanic.

Make sure your headlights are properly aligned. If they are misaligned, it can cause flickering. You can easily adjust the alignment yourself or take it to a professional.
