Truck has been in for a turbo actuator code recently. It's on again. Just found this awesome little den of knowledge and could use some advice. Owner wants the truck to go to the dealer this time because it was just in the shop for the same problem. Now we all know without some guidance they aren't going to fix it this time either. So I told the owner that we need to clean or replace the imap sensor, he good with that. Will dealers usually clean the soot and do an egr tune up or am I just dreaming? I know it is something I could do but the owner has a certain way he does things. I'm sure if I could get the dealer pointed in the right direction and get this thing running better, next time I can do exactly what needs to be done instead of slowly proceeding. Looking for suggestions on how to push the dealer and what to have them do right now.

I tried to get a KW dealer to take just the intake off and clean it up. Was told that they didn't because the tech didn't think it looked too dirty. In one of Rawze's egr tuneup videos, he makes mention that most places won't do it because you can't really clean the soot from inside the head. Might just have to call around, or look for a good repair shop and see what they say.
