How to troubleshoot a faulty headlight in an Audi A5?

One of my headlight bulbs in my Audi A5 seems to have burnt out or malfunctioned. How can I determine the cause and how do I go about fixing it on my own?

First, inspect the headlight bulb for any obvious signs of damage or wear. If the bulb looks fine, try swapping it with a working bulb from the opposite side to see if the issue is with the bulb or the wiring. If neither of these steps solves the problem, it may be an issue with the headlight assembly and you may need to consult a professional for further diagnosis and repairs.

Before attempting any repairs, consult your Audi A5 manual for specific instructions and safety precautions. You can also try cleaning the contacts and connectors for the headlight bulb to ensure a secure connection. Sometimes debris or corrosion can cause issues with the electrical connection. If this does not resolve the issue, it is best to take your car to a certified mechanic or dealership for further assistance.
