How can I fix the backup camera in my Audi A4?

The backup camera in my Audi A4 is not working properly. How can I troubleshoot and fix this issue?

First, check the camera itself to make sure it's properly connected and not obstructed. If that doesn't work, try resetting the camera system by disconnecting the battery for a few minutes.

If that still doesn't fix the issue, it could be a problem with the wiring or the camera itself. I recommend taking your car to a certified mechanic or dealership for further diagnosis and repair.
