How to troubleshoot a faulty headlight on my Audi A1?

I've noticed that one of my headlights is not working on my Audi A1. What steps should I take to troubleshoot and fix the issue?

First, check the headlight bulb to see if it needs to be replaced. If that is not the issue, then check the fuses and wiring for any damage. If everything looks good, then it could be a problem with the headlight switch or the wiring harness. Your best bet would be to take it to a mechanic for a proper diagnosis.

Before taking it to a mechanic, try cleaning the connections and contacts for the headlight. Sometimes dirty connections can cause issues. If that doesn't work, then it could be a faulty headlight control module. In that case, you may need to get it replaced.

If you have recently replaced a headlight bulb, make sure it is the correct type and properly installed. Sometimes using the wrong bulb or not installing it correctly can cause problems. If that is not the issue, then it could be a problem with the headlight leveling sensor or the headlight motor. Again, it's best to take it to a mechanic for a proper diagnosis.
