Crossing fingers. Car in the shop for parts swapping..

[TopherSho]

The following conditions may result in overboost.
•
    One or more wastegates stuck closed <---likely not opening fully.  not sure if there are pids for actual and requested.
•
    One  or  more  control  hoses  leaking/disconnected  between  wastegate  diaphragm  and  wastegate  vent
solenoid. <--- possible leak.. but i feel it a leak would have issues lower down as well as at WoT..?? am i wrong?
•
    Wastegate vent solenoid stuck in vent position <---possible.
•
    Control hoses to wastegate vent solenoid swapped.  <--- doubt this one.  no mods were made prior to failure.
•
    Hose between boost volume and wastegate vent solenoid disconnected.  <---will have ford look at the hoses.
•
    Not-yet-detected Turbocharger Boost sensor in-range failure.  <---possible but i think it is the diaphragm as Brad mentioned.

it is not starting again so its going back to the shop.  while it is in i will have them replace all the hoses that come off the turbos and wastegates.  after that im hosed.

I have a bypass on/off PID...dunno if that's any help

Did anyone get on the phone with the Hotline?

I don't think so.  so far if it doesn't have a code they are playing dumb.

No crank condition?

exactly.  no codes,  no crank attempt at all.  it goes through all the motions like it did start. sweeps the tach, cycles the air, etc.  it worked all day yesterday no issues.  this morning to cranking at all.

Fried PCM?  No codes found can be a symptom.

Did you monitor voltage while trying to start?

All of the shiny lights during startup is not an indication of cranking power.

There is a possibility that low power could cause your other issues as well, I've seen all of mine exhibit very strange behavior when the battery was in it's death throes.

Did you look for DTC's with the X4?

Never underestimate the stupidity or laziness of some Ford techs...

 

[TopherSho]

i will have to check again but we did not see any codes last time.  as to the voltage while cranking i don't have the tools .. but im sure the dealership will  

 

[TopherSho]

Update:  Bad start switch thingy.    Ford is replacing the entire Button-to-control module for the PTS.  scary part... the assembly is in back order.  since June 2017 0_0 ?

so were stealing another dealerships parts.  also getting a quote to replace the turbo... Massive pain and cost incoming.

[TopherSho]

Well in for a penny in for a pound.  Just ordered 2550$ (labor included) 2 full turbo replacements. 

sigh... 

@AJP,  I think i'm going to ask you for a copy of my last tune (with meth) with TQ management for the 1-2 shift.  I wonder if i tore up my wastegate diaphragm with the hard 1-2 shifts and all that wheel hop and shuddering.

 

[SHOdded]

  You are going to retain the old turbos, right?  Give a good onceover and stuff to see what might have gone wrong with them?  Sorry it's hitting your pockets so hard ...

 

[FoMoCoSHO]

Do they know exactly what is wrong or are they hanging parts?

 

[ajpturbo]

I guess that’s not terrible with new turbos and ford doing it...but I fear they are just changing parts even though my best guess is that the wastegate canisters are bad

And Topher I don’t think vibration is the main culprit but maybe just the age ? But sure we can look into the tune

 

[TopherSho]

Do they know exactly what is wrong or are they hanging parts?

It's a educated guess on my part with AJP providing feedback.  It is not speed sensors,  its not the solenoid, its not the connectors, junctions hoses, misfire, knock sensors, or Tq source codes etc..

Couple that with the behavior I'm pretty convinced.  If not ... well I'm going to actually set it on fire because this dealership useless.. and there are no speed shops for 100+ miles that i think can do the job.

 

[SHOdded]

... and then it turns out it is the PCM connectors that have corrosion ...

 

[ZSHO]

I would say for $2550 can the dealer guarantee any repair with certainty that replacing the turbos will fix your issue! 
Agreed with AJP and playing guessing games by throwing parts @ it will add up to a substantial amount!  Dunno!  Z

 

[TopherSho]

ye-gods i know...  It is a risk but at this point all i have left is totaling it somehow.  Hoping the predictability of the of the boost problem is mechanical as it presents itself.

Just for funsies, have you checked your baro pid for accuracy?

That is built into the PCM and if you have a failing sensor or PCM I could see that causing all kinds of hard to diag boost shenanigans

 

[TopherSho]

probably not since I have never heard of it before now :help2:  ... how does it work?

 

[FoMoCoSHO]

It is your barometric pressure sensor and very important to speed density calcs.

Oh that's the 3bar/MAP.  I have three of them.  still has the same behavior.

No, I'm talking about the baro sensor that is mounted to the pcm board.

I double checked and there is a a 3 way correlation check between the sensors at startup and it looks like another 2 way @ 1500 rpm if I'm reading it correctly.

Pgs 137, 142

I'd want to make sure its not malfunctioning outside of those conditions.

Just curious, how much is it over boosting?
