Yes there should be heat on both sides of the aux pump, it possibly has some obstruction inside it, I agree it should set a code if it isn't working. Or there may be an air lock inside that hose by the pump is maybe another possiblity. Or the pump has failed in such a way that it isn't setting a code, like the impeller is broken,

So should I also purchase a "Aux Pump" ?
I usually purchased the parts from "********" but couldn't find the part there.
So I found this one via eBay -
Motorking Mercedes Benz Auxiliary Electric Water Pump 0018351364 D065 | eBay
As for the "Duo Valve" my dad told me that the part was off another benz that was at the local pick a part.
Also the hose after the "Aux Pump" that goes to the "Duo Valve", is the coolant suppose to be coming from the "Aux Pump" to the "Duo Valve", if so wouldn't it that mean the "Aux Pump" is the reason the coolant is not getting to the "Duo Valve".. or is it both???
Sorry I'm just trying to find solution.. I don't have much knowledge about benz etc.. so anyway... thank you everyone for the help!
