Turbo Surge
Sorry to start a new thread guys but can't find what I need in the old threads. This should be an easy one for all of you. While pulling my two car hauler yesterday crusing at a steady speed of 70 my turbo surged twice, and once later after shifting from third to fourth. We all know the sound of it spooling up more when your crusing at a steady speed in OD or 6th and you barely step down on it. It whistles more. Well my truck did it all by itself without a throttle pedal change. I thought I was hearing things at first but then it did it a second and then a third time. Does this sound like the VGT actuator, EBP sensor, VGT sensor, or EGR sensor? Its an 04 with an 03 motor (build date 9/03). It only did it for a second or too. At steady throttle it just sounds like the turbo spools up by itself spinning at a million miles per hour. I don't have a boost guage yet so I can't look at it. Which sensor that might be bad would cause this in relation the throttle position? We have a really good dealership here that listens to us when our 6 oh's are broke which by the way is very rare 
. Any input is appreciated

Well Pan I am also surprised thatno one has jumped in yet.
You mention that your build date is 9/03...Have you had any reflashes and if so, when?
How many miles are currently on your truck?
Have you had any previous issues that have gone into the shop? Who, what, when, where, whatever.

I had it reflashed on 12-26-03. I've never ever had any problems with this truck since then. I had the normal problems of chugging at idle and white smoke but the reflash took care of it. It has 19,000 on it. I really think this is a sensor just starting to act up
Thanks

It could be a number of the typical sensors and actuators on this engine...but my bet would be the VGT control valve.
If it only does it rarely, and never seems to get any worse, I would probably just ignore it, but that is just me.
At this point in time, I'm not sure its reasonable to *demand* that one of these trucks work without any little quirks whatsoever. I think alot of people have been spoiled with the "smoothness" of normal gasoline EFI, and don't realize the complexity of these machines. Getting hundreds of sensors and actuators to work in complete unison all the time is extremely, extremely difficult from an engineering point of view, not to mention expensive.

I agree with you totally PSD. It hasn't done it since and like you say it wouldn't bother me to just ignore it if it rarely happens. I just was wondering what might cause it for if it ever does do it again or break.
Thanks

my truck does the same thing but the turbo will keep surging not off and on but for a long time and at idle the turbo shuts completely off and the engine sounds funny too like a cummins and the turbo dont come back on until you tap the gas and it will stay on or somtimes when you tap the gas the turbo will come on and then shut right back off. and it does'nt show up on the boost gauge.

You are right about that. Having gas engine powered vehicles all my life, I know I have been spoiled. I like the deisel sound. The power is unreal and the mpg is very nice as well. So having my first deisel has been a learning experience, learned alot from this board as well. I read the deisel bible for the 6.0, wow, that engine is very complex.
Question: (to anyone)
I am making a safe assumption here that FMC knows about these issues and is working on trying to fix them. I know Cummings helped Dodge with their deisel, is Navistar helping Ford with these issues that some of us are having?

Ford and International have a great business relationship, despite the rumors you might hear. Somewhere, recently (on here) I saw someone senselessly post that the 6.0 was soon out the door (2007) and that they were giving International thier "walking papers". These rumors are just that; and they are started by people who are willing to generate lies just because they do not like the new engines (most are just stubborn and stuck in the past). There will be an engine update in 2007- but I can ASSURE you it will be based on the original 6.0 base.
Ford and International ARE working hard to solve the problems with these engines- both companies' names rely on doing so. I think the new flash for the 2003 MY engines is a great example.

Turbos should not be noticably surging at any time unless you are on cruise control and the terrain is changing.
I would recommend taking your truck in to a dealer service department you trust.
The latest flash seems to be rock solid and seems to eliminate throttle response issues. Make sure you document everything when something happens.
I am comfortable that Ford is addressing technical issues. Now, the people issues are something else. I think inadequately trained and informed dealer service personnel are a big issue.

The service hotline is also the cause of alot of problems- if there are any Ford techs in here, you know exactly what I'm talking about

our dump bed hangs out behind the cab to the sides and up above, and catches air between the cab guard and the cab itself. going into a headwind sometimes spools the turbo up a little more. the ECM is thinking that you are going up a hill or need more accleration, when in fact you are just poking along with some throttle applied.
Were you heading into a wind? the extra cars on the trailer could have caused the momentary boost in boost,(haha
