Hi,
Just had my DS4 at the workshop again.
The camera in the right rear view mirror went totally black/dead from one minute to another and stayed dead.
Workshop found “Camera overheating” as a fault code (weird because it’s below 20C temperature outside).
Apparently there was a new software update that fixed this issue. No OTA, only cable and workshop.
The tech succeeded to trigger reboot of screens and all DS related software, this is an issue that has been happening every now and then while driving, annoying but better then black and no reboot as before.
After the update he could no longer trigger the reboot. Hopefully this was it - all the small gremlins ironed out at last!
