Bought a year old ex-demonstrator Xfrs in Jan 2017. No issues with cameras until this year and discovered this topic page while seeking information. Camera failure was regular but random and warning signs came up when mobile not just when selecting reverse. For example would get a warning whilst driving that road signs were not readable but, after a lot of problems, I am convinced that the big coincidence was the weather. Car is not garaged and was subject to extremely high temperatures on front or rear during the summer. Cooling the car either using air-con to screen when driving or sheltering it when parked used to right the problem every time. Once the temperature dropped to “normal” levels all was ok and there has been not been a hint of repetition since we lost the ambient 38/39°. Regards. Roger R
