I HAVE THE SAME ISSUE ISSUE WITH MINE A 2012 XF 3.0 DIESEL .THE CAMERA WILL WORK THEN ALL OF A SUDDEN THE SENSORS AND CAMERA WOULD GO OUT.THIS HAPPENED AT BEGINNING OF YEAR FIRST THEN WHEN THE DRY WARMER WEATHER CAME IT WAS OK .NOW WE ARE BACK TO THE COLD DAMP WEATHER THE SAME HAPPENS AGAIN.
HAVE HAD A SIMILAR PROBLEM ON MY BMW PREVIOUSLY AND WAS WONDERING IF IT WAS A SIMILAR ISSUE..I FOUND THAT TO BE A BROKEN WIRE IN THE GAITOR GOING FROM BOOTLID TO CAR BODY.
WHEN WE GET SOME DRY WEATHER I WILL LOOK.
