excessive moisture in egr valve

[williamsbuilding]

I'm sorry if I've wasted your time.
I have done egr tune up about 20k miles after inflame, including egr temp sensor, delta p, exhaust manifold pressure sensor, dpf delta-p. The back pressure sensor tube was replaced during rebuild as I requested. At this time it began passive regens again till lately. Turbo and dpf were replaced shortly after rebuild.
Egr cooler replaced at rebuild.
Doser is less than 120k miles and cleaned head whe I did egr tune up to eliminate it as suspect as best I could.
I do not yet have software. Hope to get it soon. Reason is thought it was cost prohibitive until waterloo post.
I'm not afraid to wrench a bit, but hate to do all of it on my time off.

I wouldn't be the guy to do my own inflame or head removal, don't have and don't want a full on shop.
Forgive me if I wasted you time.
