Sticking Turbo 299 code

Every time I climb a grade, I get the 299 code. My VGTs go to 15 or 85. Does this indicate my turbo is sticking?

Sure does. Clean, rebuild, replace center section or replace entire turbo. Disassembly will tell all. Three times on my 05 the turbo had to be replaced.

that code pops when the turbo is under boosting at 4lbs or more and for 5 seconds or longer.... it's sticking.

I plan on removing the turbo and/or cleaning it. I found a Ford MasterTech that will remove and clean the turbo for $300. Once the turbo is removed, it's easier to remove and replace other failure points like the EGR and oil coolers on the 6.0.

Engine EOT and ECT are in spec but the spread is high enough to concern me (12 degrees).

I have the E350 Super Duty van. It's hard to get at anything in the engine compartment. Once the turbo is removed, I may decide to do more since I am already "in there".

Are the EOT and ECT about the same after a cold soak?
