Ok, drove my truck through some more mountains on my way out of town. Much bigger than the hills it would do this on. It did it very bad, tons of times. I would give it more fuel so it shifted and stayed at higher rpms, when i would let off of it it would do that noise very fast like 3 times in a row. Got to where i was going and truck sat for a day and a half. Right before i went to leave I unplugged egr for the trip home(truck was off). Coming through the big hills it did a total of 3 times the entire way home. So it did help it but it still did it. Any ideas. I also lifted it and havent had speedo adjusted for bigger tires. Could this be part of the problem? Any updated news from you guys would be greatly appreciated.

 

anybody got any ideas???

 

EPDP99, take it to the dealer. You are under warranty. I seem to recall that when mine was going in to try and determine my problem, they changed the egr and ebp sensor as they were throwing codes. Do you have a good 6.0 tech at your dealership? That is the first step.
You have e-mail, Tim

 

I hope so since there are alot of 6.0's running around here. It will be going in next week. Did you get a code reader and delete codes from unplugging egr or if I plug it in will it reset itself?

 

I believe this info is in the Tech Folder. Here is what I have done after the egr plug "falls out", and I then have to bring it to the dealer for service:
Of course you dont want to take it in with evidence of the plug falling out. So, while the engine is off and the key is out, plug the egr plug back in. Then, disconnect the negative posts on the batteries. (I believe it was primary first, then secondary but I don't know if it really matters which one first) I let it sit for 5 or 10 minutes with the batts disconnected, then reconnect them. This should erase the memory of the plug falling out as I understand it. Take a look in the tech folder for clarification. The battery cable clamps are either 8 or 9 millimeter. I forgot which one but is one of those.
Don't worry, things will work out great and you'll be grinnin in no time, Tim

Edit: Take a look at the battery disconnect instructions in the Tech Folder in the opening page of the 6.0 Forum. There you will find step by step instructions and also info on the relearning the computer. Even if you don't do the re-learn thing, it is no beg deal as the computer will relearn it's strategy on it's own eventually. It is a real easy procedure and good info to know.
Good Luck, Tim

 

Tim, Thanks for all your help. I was super scared when it happened and until i found out egr wasnt that big of deal. Dont get me wrong brand new truck should not be doing this but not as bad as i thought. I have been on here for a while trying to learn and help when i had the v-10 now that i am a psd owner i need the info and i appreciate it.

 

No problem. I just hope that what I am addressing is in fact hitting on what you are experiencing. By what you described, it does sound like we're on the right track.
Did you read the instructions on the battery disconnect and egr info? It's good stuff to know.
Tim

 

yes I did. I will be doing it tomorrow.

 

well i havent checked it for the egr vavle opening while going up a hill yet so I dont know if it fixed that, but it does have a TON more turbo lag. I seriously think Im going 10MPH before the dang turbo kicks in. Its bad when even the wife said something about it. So far not very happy, but havent ran a tank through it yet to check mileage. Dont know if it is fixed but turbo lag got much worse. I might tell them to try to put old flash in and deal with egr surging. but maybe with the new egr it would have taken care of it. Truck doesnt seem to idle any louder either.
Service advisor says they dont get what version of software was used just said it called for upgrade.Heres what paper work says:
Multiple EGR DTC's present.P0404, P0403,monitor record EGRVP, EBPA,VGTDC.EGRVP at .89,EBPA 13.55. Removed egr valve, valve stuck open. Rec. egr valve and PCM,TCM,FICM reflash to latest level.Replaced egr valve and reflashed PCM,TCM,FICM and retested. Vehicle OP normal at this time.


Whats all this mean??(readings that is)

 

any ideas from you smartie pants out there??

 

EPDP99, sorry to hear you didn't get her done. I was hoping that we had it figured out. Anyway, thought I would reply to ya to give a bump to your thread. Hope one of these diesel lords can come up with something for you.
I think you should at least visit another reputable dealership for another opinion. Hopefully they might be able to set you up. You did call Wade right?
Good luck and keep us posted.

 

Tim, Yes I called Wade and told my dealership the info he gave me. However my dealership said ne program available but didnt know/want to tell me which one. My service advisor said he wasnt aware of any flashes that were taking care of the problems. Ill try to see what another says but am still waiting on parts from this dealership.

 

Bingo, there is your problem. As discussed earlier in this thread and in a couple others, alot of the "turbo huffing" comes from not downshifting soon enough. Part throttle shifting tables are based upon vehicle speed, and with larger tires the vehicle is shifting at too low an RPM, because the vehicle is reading a speed lower than what the truck is really traveling. These shift tables utilize what is known as an N/V value (engine speed/vehicle speed), and the self-adaptive functions which allow the computer to "learn" the correct NV value are limited in there ability to "learn" to certain values. If your tires are larger or smaller than the minimum or maximum scalar values allowed, then the shifting will always be off, even after the self-adaptive learning cycles are complete. In your case, it is simply upshifting too soon, and not downshifting soon enough.

Try running in tow/haul mode, and see if this lessens or solves the problem. If it does, it is highly likely that this is the issue. The dealer can calibrate for up to 35" tires; if your tires are larger than that you will need to go with custom tuning.

One more thing to consider...if you have tires over 33", did you regear? This will really exacerbate the problem if you haven't.

 

no I havent regeared yet, What do i need to tell them to adjust for tire size? I am running 35's now and wont go bigger. Is there anyway to reload old program and just have the computer set for tires and try that? Turbo lag got worse than it was when it went in and lift and tires were already on the truck.

 

As far as the old program is concerned, you are screwed, unless you know someone very well at the dealer who is willing to de-flash...these techs are few and far between.

If it was my truck, I would regear first, then have the computer recalibrated for both the new gears and tires. You'll notice a ton of performance difference, and quite honestly you should pick up some fuel economy too.
