I am new owner of a used 2012 M8540 HDC-1. The tubing connecting the EGR valve is severed. I have read several articles/posts about the "pros and cons" of the egr system.
Some say it's better for the engine, some say not. Then there is the environmental issue.
My main concern is for the health of the engine. I will probably re connect and test to see if the valve is working, but I would appreciate any experiences/opinions on whether or not to run the egr. One of the main reasons I bought the 2012 model was because I did not want ANY emissions controls to "mess" with. I didn't know the 2012 had egr,,,it does.
