How do I troubleshoot a low oil pressure warning in my Audi A5?

For the past week, I've been getting a low oil pressure warning every time I start my car. I checked the oil levels and they seem to be fine. What could be causing this issue and how can I troubleshoot it?

The first step in troubleshooting this issue would be to check the oil pressure sensor. It could be malfunctioning and giving out false readings. If you are not familiar with car sensors, it's best to take your car to a certified mechanic for proper diagnosis and replacement if needed.
