Ok with 215xxx miles on this bad boy, I attempted to remove the EGR valve, notice i said attempted to, not a single bolt would budge.
Sprayed them down last night with Kroil.
Put my gear wrench the bottom EGR bolt and nothing, Nadal, no budge. So I get another wrench to use as a cheater.
I put everything my 180 lbs butt could into and still nothing, finally I said F it and put all my tools up.
Not going to worry about it as there is no issues with it now, code is for valve stuck closed.
Spayed Kroil in the valve opening and will see if that has any effect.
I'd leave it be if it's stuck closed. Probably the best thing that could've happened to the engine itself.
