Just had the same issue, adblue heater fault

Good Day RACOrange, I recently had the same issue, and following the thread above went through the rigmarole of opening op the control box under the battery and found nothing out of place!! What I did do was got under the van, and removed every connector in turn, cleaned them, and then dried them with a hair drier, and then taped them up on reconnection. The adblue tank protection plastic had fallen off, so I have now replaced it with a nice sheet on stainless. So far the light and fault has not returned!!
