Wasn't your truck just in the shop for a while? They may have updated it to the latest flash, as part of their standard checklist. From what I understand, it only momentarily displays the message, instead of leaving it on the screen until it is finished.

For the short time I had my dpf on (and got this reflash), the one regen I had, I never caught on the dash... the only way I knew was because the Livewire started blinking (I have an alert set for regen). I was driving in-town and kept interrupting it too... so it had to restart like 5 times. Never saw the message once, though I don't constantly stare at my gauges, but you'd almost have to, to catch it.

So maybe you missed it? Just throwing that out there.

Oh, and to trigger it... I think someone said you can unhook the pressure sensor's wire for a second while the engine is on to trigger it. For example, start the engine, crawl under, disconnect the pressure sensor, reconnect the pressure sensor, regen. I'm not 100% sure on that. Haven't tried it myself.

Yeah, I think the newest flash only displays the message for a second... making it easy to miss. You've probably regen'ed more often than you think. I noticed on mine, while the dpf was on for 2 weeks, the regens with that flash had very good manners and were barely noticeable. They're still washing the cylinder walls with fuel, so, its back off now. Thats all the details I have from the short time it was on.

Ford just put this latest update on mine. I noticed the cleaning exaust show for about 2 seconds. Is this Fords way of making us quit *****ing about regen? I can usually tell when it is cleaning exaust becasue it smells hot and runs a little different but I prefered to see it on the dash. I drive a lot of 20 minute trips in the city. It usually goes into regen a few minutes before I get to work so I never know if it ever gets cleaned through a full cycle now.
