360 ° camera is sometimes dark

Hello dear DS specialists ! On and by myself I am fully satisfied with the 306 ° camera. Strictly sharp and very good even in the dark. However, it has already happened to me for the second time that the camera delivers very dark pictures, so that I can perceive almost only more outlines of the environment. Remedy only creates engine shut down and restart. An example: I park out of the garage – normal picture. Drive shopping – when in – and park out also normal picture. I come nac h Home and park me in the garage – environment only dark perceptible. Camera is not dirty !!!! Did any of you have such a problem and how did you solve it? Thank you very much for your help !!!! P.S. otherwise our new DS 4 Rivoli is an absolute HIT and eye-catcher !!!!!!
