Ok, its ben a while since ive had a diesel, but ive got this weird noise ive noticed,that shows all different times,no pattern. sometimes it will stay a few days, others it wont,sometime back and forth during the day.
video #1 is normal operation and sound,video #2 is the strange rattling sound almost at idle and at the end of the rev in low rpm,almost sounds like if you put your car in park before youve stopped completely,metal on metal?.....is it normal? ford says its air in the turbo pipes (yeah right) let me know what you think, and turn up the volume!

It does sound like some form of resonance. Whether its exhaust or intake I can't tell. Is the intake system stock or modified? Also, if you do a lot of short trip driving you may be catching it during its exhaust cleaning cycle, which will change the exhaust system dynamics -- possibly causing some acoustic anomalies. These are just some ideas that went through my head (which is also a short trip). Edit -- If you've modified the exhaust system in any way, such as deleting the the resonator, you'll get all kinds of new sounds. I did some exhaust mods. on my '06 which caused it to sound like the turbo was clawing its way down the pipe upon shutdown.

Nope, no mods yet, 2000 miles on it, and the noise sound comes from the eng compartment. Very metalic, like two gears not quite meshing, and rubbing against each other.

I feel as though it is fuel is being injected at different times, which does make it clatter at different times. mine at times after i get off of a highway ramp. wow its loud. then it gradually gets quite. dang reminded me of the good ole 7.3

ok, i stopped by a big local dealer today and the diesel tech said he never heard the noise before, and thought it might be something plastic behind the intake....my buddy who is a tech for dodge the past 25 years put a long screwdiver on the fuel lines and put his ear to it and said he thinks its "fuel related" he said a couple of lines where clanking like crazy...maybe a bad injectoy or fuel pump??....runs fine,no codes.

sounds like regen

Mine makes a similiar sound during regen. I have never stopped during a regen so I dont know how it sounds at idle but at highway speed i hear a similiar sound during regen, alhough obviously a lot harder to hear. sounds like a surging in the engine. It would be a fuel related sound since fuel is being dumped into engine during a regen to heat up exhaust.

Unless Ford has changed the regen Strategy, when in park, it's not happening. Passive and active both happen while in gear. As soon as you go to park, netural or apply the parking brake, regen stops.

Don't make fun of me for referring you here, but thought it worth a shot. I have a strange clunking front end noise in mine, and I'd want any recommendations I could get.

Might try this thread: raw diesel in cab on regen. Not sure if you've noticed any diesel fumes, but the fitting referenced in this thread might be loose causing some sort of pressure or air noise?

No clue, just thinking aloud and trying to help.
