What is the actual DTC code?
You can check whether or not the haldex oil pump is working by removing electrical connector and connecting a 9v radio battery across the terminals.
You should be able to hear the pump.
You can also get live data via VIDA/DICE of some haldex/dem conponents.
As you cant rotate propshaft it would suggest issue is in the Haldex unit/components or the DEM.
