How do I troubleshoot a malfunctioning rearview camera in my Audi A8?

I noticed that my rearview camera in my Audi A8 is not working properly, showing blurry or distorted images. What could be the possible causes of this issue and how can I fix it?

One possibility could be a dirty camera lens, which can cause blurriness and distortion. Try cleaning the lens with a soft, damp cloth and see if that improves the image quality. If not, it could be a faulty camera module that needs to be replaced.

Another potential cause could be a loose or damaged camera wiring. Check the wiring connections and make sure they are secure and undamaged. If necessary, you may need to replace the wiring to fix the issue.
