Not sure how you have measured these voltages nor what they signify.
I basically worked out that if there was power to the DEM, the pump could be heard to start any issue with the Haldex unit was either the DEM controller, the pressure switch, or the the solenoid.
The solenoid I checked out using a 9v radio battery. A member on here lent me a known good pressure switch to substitute, which then left the DEM as the prime suspect despite being given a clean bill of health by BBA.
The unit was rechecked by Lucus, found to be faulty and a recon unit supplied. Plugged straight in and worked out of the box.
One thing I did have was very dirty Haldex oil. I had oil stored in glass jars which had 1" of sediment in the bottom after 24hrs standing.. I "changed" oil well over 6 times before I noticed an improvement in the quality.
Good luck
