I bought a 2012 XF a year ago. Shortly after the camera stopped working for a couple of weeks, then started working ok again. Then last week the wipers went crazy. They eventually stopped altogether. I had to pull over and turn off the engine, then after a couple of minutes they started again. Now this morning the camera has stopped again with the dreaded "refer to dealer" message. The loom in the boot seems to be a frequent problem but I'm wondering whether, given the wiper issue, it might be the battery?
