From what I have seen, and heard...the dealership will look at the heads, but thats about it.
They will most likely replace the gaskets, and thats all...that way, when they go again...it's on your tab, not theirs.
They may install studs for you, but prolly say that it will void your warranty.
The use new bolts, not studs. (They are a torque-to-yield...read: "Throw-away")
They will not delete your EGR for you.
Good luck.
I am realizing why most people trade them in and get something else, or move to a different brand....Cuz no one can afford to fix these Diesel engines once they are out of warranty.
The saying: "If you want to play, you gotta pay" should be: "If you win a lottery...go for it."
