Ford change Turbo strategy instead of Replacing Turbo ???
My 2006 6.0 has been making some strange sounds for the past month so I took it in to the dealer. It was making a squealing sound that you could hear really loud at idle or when you were pulling a load down hill and you let off the throttle (Normally you wouldn't hear anything).
Anyway the tech said he was 95% sure it was the inner parts of the VGT. He called to say he was waiting on approval from ford. He calls back and says Ford wants to change the turbo strategy and not replace. The tech had told me there was some updated components for the turbo, but when he pulled it apart, my truck had the updated components.
So what's the deal, is Ford just buying time before the Turbo goes out? Will changing the turbo strategy change the boost or the way the truck drives?
2006 6.0 40k miles. Well maintained, No mods whatsoever.
Ford will often have tech's "recondition" the turbos - I would bet that's what the tech meant. I can see how a new strategy will remedy a mechanical issue.
No strategy. They are talking about the turbo center section. This is the part of the turbo that houses the bearings and compressor wheels. As per TSB 08-16-03, if a turbocharger fails testing and is torn down one of three things happen. 1. Coking deposits present, no corrosion or mechanical damage. Turbo gets cleaned and updated turbo drain tube installed. 2. Coking or corrosion present on the center housing (CHRA), replacement of the center section is required. Turbo vanes and unison ring are cleaned, CHRA replaced, updated turbo drain tube installed. 3. Unison ring is cracked, vanes are damaged, compressor wheel missing/damaged. Complete turbo gets installed minus VGT solenoid. Replacement of the complete turbo assembly is rare. Non level 1 dealers (warranty) are required to obtain prior approval to replace the turbocharger assembly (calling Ford). The squealing noise you are talking about could have been a problem with the CHRA, since the tech went in that direction. Replacing the CHRA is basically replacing 80% of the turbo and by doing this, cleaning the vanes and ring, and applying anti-seize, there should not be any more problems as far as sticking goes. When the turbo poops a compressor wheel down the down pipe, that's another story.

Thanks for all the info. The tech specifically said they had updated the programming? Maybe he was talking about an updated flash?
I just thought it was odd to talk to the guy running the fleet department; him telling me he's going to change some of the inner components of the turbo except the housing; but he was just waiting on the okay from Ford. Then he calls me back saying that he looked at the turbo and I have the updated parts and Ford wants to try changing the programing/ strategy. Maybe he just applied some anti-sieze compound to stop the squealing.
I'll see how it runs tomorrow. Thanks for your help.
Um, that ain't the turbo dude. If it is still doing it don't take delivery back from the dealer. I would also point them to the video, since now it is documented they can't hide it.

Hank..what I hear is a "scraping type sound" If still there when you go to pick up..I wouldn't sign off on it. Actually tech. shouldn't release if noise still there. JMO
But, what is that noise? AFAIK..your 06 t. is diff. (part wise) than my 03. Changes made VGT 03/06 6L TURBO Your tech. already confirmed. When mine started drying..it didn't make noise like I hear in your sound video.
Maybe t. can make that noise..or..pulley or ? Good luck!
btw..I doubt any reflash would cause noise to go away if thats the plan, but??
