I removed the egr today to check it out, would like to know what is the best way to clean out the interior of the valve? Is there somthing better than carb cleaner spray, I have a bucket of carb cleaner and could submerige the bottom part of the valve, its steel, the small cyclinder that moves up and down i’m not sure of!
I bench tested the valve and all coils move when energised. I placed a small scre driver in the ports and 2 were free, 1 would not move, I didn’t force it, but it does move when power is put to it.It is the on with the most carbon in it. 2 of the ports do not close all the way, but close to it.
