I brought my truck to the dealer with a overheating problem only to get the "no code, nothing we can do" story. But the new PCM flash was needed so they did that. Ran the truck for about 20 miles when wrench came on. Now the dealer has it and is talking with the Ford engineer. They still can't find the problem, but now the wrench keeps coming on so they know it's something other than me. So it looks like the upgrade is doing its job, now if the techs can just do their's and fix my truck (I'm in the middle of my third week).
So those of you worried about the upgrade, all I can say is that the computer is now picking up that somthing is wrong, which it didn't before.
Very interesting. I wonder if anything else will change with the new programming. I recall some older flashes showed the "cleaning exhaust filter" message while others dont. It will be interesting to see the feedback from those getting this done early.
I had a termostat changed in M.S.
They flashed the computer without notifying me.
On my way back home to S.C.
I noticed that the "Cleaning Exaust Sytem" Hasn't appeared in over 400 miles. The followigng Monday I drove to N.C. Still no CES message.
I stoped to a ford Dealer in NC and told him of my problem.
He looked on his PC and told me they had flashed it, and it may need to be reflash. Set up an appointment for the following Wednesday.
Well low and behold, on Tuesday I saw a message "Drive to Clean Exhaust" First thing I did was to jump on the HYW till it was completed.
Since then I kept an eye on the dash and the message "Cleaning Exhaust Sytem" would apear for a second ot two. Then I would feel it kick in.
To my understanding. The 6.4 may stall if it doesn't clean the exhaust.
I have a F450 Altec Bucket truck,with a 40 foot bucket . With a PTO "Pump" to the transmission to control the bucket. When I engage it, the engine revs up to 1300Rpm, and the engine idles like this sometime for half hour or more.
On Friday I had the dealer reprogram the PCM in my 2008 F-350 as instructed by the letter I received. I just about made it home when the Drain Fuel Sep message came on. I drained it and restarted the truck. The same message came on but now the wrench was on. I attempted to drive to work but now the truck was in the limp mode. 2500 rpm 40 MPH - had to let up between shifts to get it to 65. Had to drive back 45 miles to dealer to have them check it out. They came back and said it needed all the fuel filters changed and the bottom of the fuel filter cleaned out. They said it also needed two batteries. Now keep in mind the old programing said everything was fine and with the new program now two systems failed. Ford "Raised" the bar for the sensors with this new program and now systems will show errors sooner. I could have replaced the batteries and fuel filters myself but had no way of erasing the codes. And I did not know if they would reset themselves. With it being the Labor Day Weekend and me needing to get to a Car Show and swap meet on Sunday (with my 10,000 lb trailer) they had me over a barrel...
End result, the FREE computer upgrade cost me $419.00... Not Happy
To top it off the service writer tells me "You'll get a survey to fill out, I know you had some problems but could you fill out that everything was fine. If you don't they'll take $200 out of my pay. If you say everything is fine I'll get $100" Thanks for using Brandon Ford...
It's pretty important. It updates all the early detection parameters to prevent issues down the road as well as various other adjustments. It has also been reported on the letter that if there is any issue that could have been prevented by the flash, you could be denied the warranty repair.
If you have a good rapport with your dealer, I would hit them up for the rental.
