Volvo EGR help!

[mayhem1]

I have a 2012 Volvo VNM with D13 that is having severe regen issues. Only code was Mid 128 Sid 146 Fmi 3 Engine ECU Egr valve voltage above normal or shorted to higher voltage. Dash says 2791 fmi 3 which is same. Replaced egr and same issue. would not do a regen and there is no voltage at two wires that plug to egr. I presumed it should have been 5 volts since other sensors were. Traced both wires all the way to ecm plug. Found some oil in ecm plugs, cleaned and still same issue. No voltage on wire and egr code still active. I have called myself double checking everything, but can't belive old and new egr have same issues. can't do a manual regen neither. cleaned seventh injector that was carboned up. When a try to do manual regen everything is green and says nothing is prohibiting it from happening. What am I missing?
