I've been lurking around here for years and can usually find the answers I need from this great site; but I just don't have time to research this one at this moment.
I have a 2006 F250 6.0 with 49,000 miles on it. I bought the truck with 20,000 miles on it and have had good luck with it so far. I change the oil and filter every 5k and fuel filter every 10k. Always use ford filters and mobil oil (delvac 15-40). Always use reliable fuel (pilot or speedway) and proper adative.
@ 39632 miles (12/08) had check engine light on (code P0299) dealer finds lots of soot in turbo and a bad vgt actuator. They said they cleaned all the soot out of the intake and the turbo and replaced the vgt acuator under warranty.
Now at 49950 miles I have the check engine light on again (code P0299 & P0611)dealer says it's a bad egr valve and lots of soot in the intake. They say the egr valve is warranty but I have to pay inexcess of $500 for the intake and the injectors to be cleaned (320 for intake 180 injectors). Then they tell me that I have to pay a $100 deductible on top of the $500. When I catch them on the fact that there is not a deductible on emission coverage they become defensive. When I ask what the "root cause" (wording out of tsb 06-4-12) of the soot is they tell me it's the oil I use. When I prove that the oil is the proper specs they then say it's my choice of fuel. I don't believe that they have any idea as to the cause of the excessive soot. Am I wrong to think that the cleaning of the intake and injectors if necessary should be covered by warranty? They say that cleaning the intake is a maintenance issue and that I should do it every 15k @ $320 a pop. Is it me or is the dealer trying to pork me?
Sorry for the long post just wanted to make sure y'all had as much info as possible.

 

goto another dealer. if its not in your manual as a maintenace, its not needed for you to get warranty coverage.

 

....and also report the bribery to Ford. I betcha if you tell the service manager you are reporting that to Ford, they will do an about face.

 

I hate this. There is a tsb that covers coking and if its that bad then its a covered concern or at least our shop. What they are tring to sell you is a chemical cleaning broght to you be the nice guys at "bg". This is not a service I by into, nor one that ford motor co recomends you wont find injector service in the service/maintance guide.

I cover this a few days ago. the fuel pressure at the tip of the nozzle can reach beyond 24,000 psi. if you can find something that will plug that hole Im willing to bet you wont get it unpluged.

now lets look at the p0299 and p0611 codes. the underboost p0299 is caused by a few things. all of what relates to engine fueling of some type or an exhaust concern . this means egr concerns, fuel pressure, low or poor quality oil, injectors.
now lets look at little bit at the p0611. when the ficm fails you get fuel and injector issues. reread above what cause's the p0299. so what it comes down to is a failed opr failing ficm can easly set codes for boost. not only boost but it will effect egr flow when boost goes low becasue it will be tring to compensate to make the motor run so you can get p0404,p0401 codes. A nother result is a p0470 for ebp can come in to play with a ficm because the ecm will change back pressure with the egr and vgt to try and produce enugh power/boost to run and when it cant you will pop the p0299.

now back to the intake cleaning. Its very possible that a failed ficm can lead to coking in the intake. and infact that would be from fuel. as the tsb states ttah any injector under 15rpm could lead to excessive coking. so in theory yes they could be right about fuel as the source but then the condition would be caused by the failed ficm and once agian warranty.

IM A TECH and thats my .02

if this is as clear as mud let me know what you dont understand and Ill see if I can explain more.

 

Well your .02 means alot...Way to go cheezit

 

Cheezit, that was more than 2 cents, looks to me like it was almost a dollar. That is what makes this site great, people like you with great knowledge helping those of us looking to learn. Thanks Cheezit and others for your expertise.

 

Exactly what he said!

It's great to hear from the experts on these 6.0 motors so we can all figure out what the heck is going on with our trucks when they have issues!

 

Gentelmen, thanks for all the imput.
Cheezeit, if I understand you correctly you agree that its a fuel issue however you believe it is a fuel delivery (ficm & or injector) problem not a fuel quality problem. Bottom line since they failed to identify and correct the root cause I will be going through this again in the future...but not at this dealership. I finally agreed to pay 1/2 of their original price for the intake cleaning just so I could get my truck back on the road. They won the battle (they got me for $160) but I won the war. Unknown to the "new" service writer who stuck it to me my partner and I were susposed to pick up a new 2010 truck today. Since the dealership's integrity is now questionable we walked away from the deal! Neither my partner nor myself nor our company will ever do business with this dealership ever again.
Thanks again for all the help!

 

from a tech stand point its a fuel condition, there is no way to go beyond that if you have an injector misfireing and the root casue of the misfire, runs rough etc is a failed ficm.

glad to be of help.

 

It really surprises me what some dealers will do to their customers, or should I say what they won't do! They need to look at the big picture and realize that if they eat $100 dollars today and make me happy then I'll gladly return and bring more money their way during my trucks ownership! That $160 they charged you may actually cause them to miss out on $1000 or more in the future! Customers being displeased or feeling ripped off or just not feeling taken care of is a bad thing for a car dealer! What ever happened to customer service and simply just doing the right thing? I guess they would rather get your $160 today even if you never come back to them?
