Hello and welcome 
Low beam fld vision falt on dash (what ever the hell that is?)
Comes up sometimes on mine, it is due lack of communication from ecu to headlight controller, don't worry about it to much, I don't. I have past 2 MOT's with it appearing from time to time.
Do check on the passenger side wheel arch that your wire loom to headlight is not rubbing, this is easiest, in my experience from underneath 
Welcome to OOF

If yours is a pre or mini facelift there are 2 sensors - one on front passenger wishbone and one on rear passenger suspension arm. Normal problem with these is that arm has popped off socket - easy cure. Also check elec plugs in fully and contacts clean - again a no cost check.
If its not that one or both sensors could be breaked.
OR servo motors on back of headlights could be breaked - altho some members have removed them, cleaned them up and regreased with +ve results.
