2011 Volvo FM Com Data Bus Adblue Abnormal upload rate

Hi All,
I have a 2011 Volvo that is coming up with a adblue fault.
The fault code is
Communication data bus Adblue module managment, abnormal update rate.
Data Link, Instrument System, Abnormal update rate

The auto elec cant get any signal back from the adblue module, which leads me to believe the module is faulty? anyone had this before?

Can volvo reflash/program the module?

Cheers,
Nick
