So I received the EGR Recall fix last week. My 2016 ecodiesel was already in the shop awaiting parts first for EGR and then for a intake manifold they broke while doing the EGR. So when I received it this time they stated it would have a whistling sound. And I can choke down a mild whistling sound.... but mine is quite loud and annoying! Has anyone else received theirs and also has a whistling sound. I dont believe this is right... and have been told by another mechanic that he believes it's a pressure leak. Any feed back is appreciated!!
