Hi! It is super common
problem to 2020 and early 2021 MY. Not sure what is you warranty time but in Latvia it is 5years or 100k km. In 60k km run I had this
problem twice. Both times changed by warranty. So if your car still has warranty. Contact dealer and they should change it on their own charge. No costs should be applied to you. As across EU we have the same warranty rules. Maybe for GB has something different since Brexit. Wish you luck and hope any infotainment bugs wont happen.

As for putting back, by yourself, not sure you will get any good image quality as the lens should be calibrated- atleast that said my dealership in LV.
