Hi there. I bought a 2012 XF about a year ago. Shortly after the reversing camera stopped working but a couple of weeks later it was fine. Last week the windscreen wipers started doing bizarre things, eventually stopping altogether in a vertical position. I shut everything down for a minute and they started working again but not in any happy way. This morning the camera went off again. Hmmmm. I’m thinking maybe the battery might be getting low? Any other suggestions?
