Front assist no sensor view & screenwash fuse blown

Hi all, recently had "front assist no sensor view" pop up on the dash & on the infotainment screen after a couple of freezing nights, the warning comes on intermittently & sometimes will stay on until the engine is turned off or will just pop up for a few seconds. 

I also had the screenwash fuse blow as well, but that could have been due to me trying the screen wash while it was frozen up & the front assist warning error started around the same time as the fuse blew, so I don't know if the problem is related but I replaced fuse 22 & the screenwash seems to be working fine, I also checked fuse 37 which is for the radar but it hasn't blown.

Is it a known fault that requires yet another visit to the dealers or is it just a temporary glitch?

TIA
