I was driving into work this morning and I started to hear what sounded like my turbo surging. My boost psi did not fluctuate on my monitor and the truck ran good, it just would just start to whistle and get louder and then get quiet again even with the cruise control or on flat roads.

I checked for DTC's on my monitor and there were none. Any thoughts?

Sounds like your VGT Solenoid. About 90 bucks on ebay with shipping. Had the same problem on my 05. Switched it out and it ran perfect....no more surging issues.

I just looked on e-bay and they are going for $249.95. I have no problem with that but is there a way to confirm that the solonoid is going bad and need replacing.

Ford Turbo Powerstroke 6.0 Turbocharger VGT solenoid | eBay

that one is only $35 but it's used....can't beat that.


ford oem 6.0 powerstroke vgt solenoid (turbo actuator) | eBay

this one is new and its $190



the only way i know of testing it is to get a known good one and swapping them out. If it fixes the issue you know it's the solenoid.

Explain "surging" more.

If you have access to a good scan tool you can test it with a vane sweep. Your surging could also be sticking turbo vanes. Just guesses from this side. Test,verify,repair.
