The sensor/system might need resetting which will be the easiest option. As such is recommend a diagnostic check. The sensor might need replacing. 

It could also be the pump as it was in this case:

Hello Conner,

Probably best to send Thomas a PM since he hasn’t returned to the forum since the day after he first posted. 
Kind regards,

Gareth.

It could be the ssensor, float in the tank.

Tank you everybody. The problem solved! We did the normal resetting procedure. Everything is fine. Switch on the ignition and wait the one minute and then off. Wait the one minute again. Done.

Hi the Adblue filler is next to the fuel filler its circular and made of plastic with a 17mm plastic bolt on the top, if its the filler flap that won't open there is an emergency release red cable behind the boot trim that side.
