My old xc70 had rear haldex noise, they changed under warranty, but the diagnosis took ages as thoughts were tyres, bearings, even brakes first.

The ERAD is the complete unit at the back consisting of the motor and the clutch/gearing. The well publicised ERAD failures are almost exclusively the clutch/gearing which is repaired by the dealer using the repair kit. This kit is modified from the original design.
It sounds in this case that the OP has had the ERAD repair done to the clutch/gearing, but now the motor has failed too which is I think very rare.
