During a regen cycle the EGT is ramped up very high to burn off crap in the DPF. This high EGT no doubt has an effect on the turbo due to the fact that the exhaust is what spins the turbo to generate boost.
Very high EGTs is what kills Diesels and limits power output.

The high exhaust temp occurs at the catalyst, downstream of the turbo.
This Diesel engine is not experiancing "very high EGTs", the DPF and exhaust system downstream is.
I don't see how anyone can even think its fair to claim warrenty work on a chipped or modded vehicle.
Don't think a new intake will hurt anything though.
All the hits FMCO took over the years in warrenty work from modded chipped diesels, you did it to yourself.
IMO...The only way a new intake mod could hurt anything would be if it were installed incorrectly...and that caused excessive dirt to enter the system. Or...if the new intake does not filter the same as the FORD OEM unit...which would allow more to pass the new intake air filter. Which could result in damaging the turbo(s).

Another factor to consider is that once aftermarket mods are installed that change the inputs the computer sees as normal to an out of range condition, further diagnostics to Ford's satisfaction for a warranty claim likely range somewhere between difficult and impossible.
A warranty can not be voided out of hand. The Warrantor must prove that a modification caused the failure you seek to have repaired.
Typically, the Dealers who "flag" your warranty are those who have a high warranty expense in relation to other Dealer of the same size. If the Dealers waranty expenses are high in a given catagorey, the manufactuer can require the Dealer get prior approval for the repair. As a factory rep for 20 + years, I dealt with the issue on occasion, refusing warranty is very difficult. If you maintain your truck (retain all reciepts) denial of a claim is not likely; unless any modification can be shown to directly cause the claimed failure, the factory must take care of it.
The FoMoCo rep stated to me that any modification to the exhaust, intake or tuning of the truck would directly void powertrain warranty. You gentlemen need to re-read my first and second posts on this thread. No where did I say that I thought it was wrong of them to void my powertrain warranty, when I bought the truck I had to sign a waiver form stating I understood that if I modded the exhaust, intake, or tuning of the engine in any way shape or form that I would loose my powertrain warranty. I understood this from day one. I am not arguing the fact that they voided my powertrain, but what I am disputing is the fact that a) they didnt notify me, b) they tried to void out my entire warranty.
I have said from day one, "You gotta pay to play" and thats the motto I live by. I just think its BS they tried to hammer my entire warranty over this whole ordeal.
And for the record, once again, the SCT tuner was NOT installed in the truck, nor has it ever been.

So in order to buy a 6.4 Ford you have to sign that type of form stating if you make mods to those certain thing it will void your warranty on the powertrain?
This is the 2nd time I have heard this, about that form when you purchase a new 6.4.
If that's the case, and you signed a form like that the Magnusson warranty act is irrelevant then. All they have to do now is pull out that signed form and say you modded the PCM or exhaust so you have agreed by signing this form that your powertrain warranty will be voided.
If that is the case I am afraid I would have to give the salesman the finger and walk away!

I thought when the dealer went to ask you about mods and warranty you said.........and I quote.
"Noooo
They know better".
I understood this from day one. I am not arguing the fact that they voided my powertrain, but what I am disputing is the fact that a) they didnt notify me,
Cowboy Steve
They notified you when you signed that paper...and then you made the mods. Kinda...like you notified yourself!
That is unless you forgot you signed that paper?!?
I do agree...that the entire warranty should not be void. Heck...if your radio goes out...YES...FORD should pay.
why in the world would a moderator need to see a vin# to verify any bodies story!!??? you guys are absurd! Why would Steve make up this story. He PM'ed me the day he got a call from the dealer asking if he was interested in a new truck. That was months ago and his story has never changed once! Get a life!
I am not saying he is making it up. I just know he was asked for a vin# very early in these posts. I just wondered it it had ever been provided. For anyone who might be considering modifying a new truck it is important to know whether people are running into problems with these trucks and mods or not.
edit: It was a moderator that asked for the vin. It would allow them to look at the actual reports on the truck. That would give info on what actions were taken with the truck and what else was written about it. It would give all of us lots of info even the owner of the truck does not know and can not see.

The mods would need to see a VIN because some have access to the oasis system and are able to run the reports. Not that it really matters, if he has the truck the dealer should have voided the powertrain warrenty and nothing else. If he doesn't have the truck (which sometimes it seems that way), well then I guess there's no point to this or any other of his threads and we've all been had.
