What happens if you don't change the cam phaser?

Some trucks didn’t have a cold start rattle but could exhibit a knock noise at hot idle; the calibration corrects that issue. Which is the reason the reprogramming should have been done first.

Not really. The general public spends far too much time and effort speculating about things via the internet instead of just following the manufacturer’s direction.

The recall was straightforward. Receive letter, schedule appointment, have the update done, and you get the extended coverage.

Yea i feel ya. That makes sense on the hot idle. Some of us have had bad luck with Manufacturer programs in the past. Many that dont work, ie freezing door locks. I cant get calibration engineers to completely agree with all of this either, so everyone still seems to have their own opinion. Calibration 101 answer, software can only do so much to solve long term durability issues if the hardware isnt up to the duty cycle.

So I had my PCM updated today at the dealer. When I scan now with forscan, it doesnt show that the strategy has changed.

@FordTechOne , Do I have to do anything special with Forscan to make sure its pulling the latest data from the PCM after connection?

Well, I had to force it to create a new profile. Maybe forscan doesn't update each module revision each time you connect. Weird.

problem solved.

For what its worth, i had 100k on my 2017 had no issues but a very slight tick, Had the ford dealer do the cam phaser recall and the motor blew 45 miles later, from what i could tell they did not get the cam phaser timing correct the motor was scorched black from heat when torn down
Ford replaced the motor with a new long block, ( i had the extended warranty on it) if not iam not sure how that would have gone.

yea thats sadly poor quality workmanship issues. Thats why its always better to avoid invasive procedures if at all possible, sad but true.

When my phasers were done in Nov 21, i had another fun "issue" that magically fixed itself, again, which is just another reason why I don't trust without verify.

For about the first month after I had the phasers done, upon cold start and only if it was nice a cold/damp day/night/evening, about 30-45 seconds after startup I got a nice knocking sound similar to the knock at hot idle that I had prior to phaser replacement that would go on for about 15-20 seconds then clear up. I had engineers from ford engaged that were working with dealers on the program, no one could figure it out. We went back and forth for a month on what to do (mostly because the dealer then put me to the back of the line in their schedule if they needed to be redone which is a completely different issue) and if the motor needed to be opened back up then about the time they were going to redo the job, it magically fixed itself, never to be heard again, like the motor knew just to screw with us long enough. Of course thats not what happened as its an inadimate object, but this is 100 percent why my distrust of accepting things on the service from an OEM runs deep in addition to all the other things like the freezing door lock concern that are super invasive, mostly get screwed up and still dont work, so I've never had that done either after issues with friends trucks.

Ford really needs to provide more detail on why things are happening, not just "this is what you have to do" to put people at ease vs having to find this via techs and such on youtube. I deal with the Fortune just about everything in my day job and when we make software changes, customers ask a lot of questions because its their business that our software runs, they are the ones left holding the bag if something goes wrong and being able to provide answers to put them at ease goes a long way. Something the auto industry hasnt figured out and may never figure out.

The real kicker in all this. This is at major dealers in SE Michigan, Fords home, if there was a place for quick issue resolution, you would think it would be here.

I still bought a new maverick recently to add to the fleet, i guess I like pain, or maybe the devil you know (Ford) is better than the devil you don't know (any other oem domestic or foreign). That being said I got a late production 24 Maverick on purpose and built it as simple as possible, its been fantastic for the 2 mo, 2k miles I've had it.

Another topic for another time, but being someone in software, it hurts my soul that I dont get free updates to all modules in my vehicle, I understand there are logistical issues there as its not over the air, but i hate seeing things not updated when I run forscan. Sometimes updates that fix issues, but are unknown unless you pay a dealer to diagnose them, its a complete disaster of a process, when if you just got all the updates like on your phone issues you may even never know you had go away. But like i said a debate and rant for another day. Also, why aren't all the software module updates release notes freely available on the interwebs on Fords site just like any other software maker for business and or consumer?

I think the answer for the auto industry lies somewhere in the middle of the Tesla and legacy model. There are things like software that need to auto update, or be freely available with consent, but things like hardware changes need to be monitored more closely in the design / manufacturing process, which i heard tesla doesnt do as well as the legacy OEMs.



Ok rant over.

I've been wanting to get my 2017 done, get a half second diesel rattle on cold starts and then it's quiet. I don't think it's ever had the updated programing.

Got the update to both the ECM and TCM a few weeks ago and it seems just as noisy on cold start as before. Shortly there after I installed the Cobb tunes for both computers and that seemed to have helped a little. Rattle is still there but just a hair quieter, idles smoother and of course shifts a lot better. I'm not too worried about it but would like to get them changed at some point just out of annoyance.
