Automatic headlight light sensor

Hi, I noticed my auto lights aren't working.. It looks like the sensor is missing completely! Does anyone have any instructions on replacing the sensor? Do i have to get it direct from renault? Also, the interior trim at the top of the windscreen doesn't seem to be fitted properly, so obviously, a previous owner has bodged it. If anyone has disassembly/ reassembly experience with that, it would be appreciated

Do you have the auto headlights activated? I haven't heard of this issue before. Unless it is a replacement windscreen...

Teied to switch on auto headlights, got a message saying they don't work (can't remember the message exactly) checked where the sensor should be on the windscreen, the 'gel' sticker is still on the windscreen but nothing behind it
