Seems to be made well, and the rest on this ecu also the time the delete well. Which errors do you from? but the position of the egr varies in diagnosis? however, on this machine errors EGR, can also not hit with the egr, but them why? are caused by other components.
So it should be one of the egr.... in many cases, for?, not ? the egr itself the cause of the errors on the egr, but the other. However, make sure that it is functioning as an electrical part. But the elimination as you made it?
