DPF Manual Regeneration
Hi,
I just bought a 2022 F350 with the 6.7L Powerstroke Diesel. I paid an extra $250 to get the manual regeneration feature for the DPF.
I didn't realize in order to do a manual regen the truck has to be stationary, otherwise I wouldn't have paid for the option.
I just can't find much information on exactly how to start a manual regeneration. I can't find a button anywhere.
When the DPF gage showed approx 75% full at approx 500 miles the truck did an automatic regeneration. Only way I knew
was because my mileage went way down, the DEF gage went down and the DPF gage went back to 0% Full.
I've seen some videos and it looks like the filter must be at least 80% Full then you will have the option of doing a manual
regeneration. Right now my DPF Filter is at 75% and I can't find anywhere where I have the option of doing a Manual regen.
Only reason I can see to do a manual regen is if you don't drive long enough to allow the Truck to complete automatic Regen cycle.
Can someone please enlighten me on this issue?

I don't know about how to trigger the manual regen, I suspect the option will show up in the gauge cluster screen if the truck is at a point where regen is needed.
But, you said something about the DEF gauge moving when it did its automatic regen, you know the DEF has nothing to do with regen or the DPF? They are separate systems. If the DEF gauge moved during the regen process, it must have just been coincidental.

This is my second 6.7L Powerstroke Diesel, I had a 2017 also. My DEF level always went down after a regen.
Usually like an 18th of a tan or so.

On my 17' I had the dealer turn on the OCR. It also gave me the dpf %gauge on the cluster. The only way I could do a manual Regen was when the dpf was at 100%. The cluster would read exhaust filter full or 100%. Something like that. If I just kept driving it would automatically start a Regen about 5-8 miles after seeing the message. Then you cannot do a manual one. If I stopped when it read full, then I could put it in park and it would say hold ok button to clean exhaust filter. Then the Regen would start. 2K rpm for about 25 min. Don't have the option on my 21'. Haven't done the forscan option yet.
bottom line is the exhaust filter has to be whatever the computer thinks is "full" to do a manual one.

I have not seen where I can turn off Auto Regen. But I'll look again. I knew about Forscan but was leery about using it at first. But when I got my new 2022 and they have the rear tire pressure TPMS value set
to 80 pds. I decided to purchase the Forscan software so I could reset the value to 60 pds ad eliminate the constant alarm. As I run empty most of the time. Should have just activated manual regen with Forscan and not paid for the option.

Thanks for the detailed info. I initially wanted Manual regen so I could trigger Regen at a time I felt was appropriate when the Filter was starting to get Full like around 75-80% Full
For instance when I would be driving long enough to complete the cycle.
To avoid the times where it didn't complete and would have to Regen the next time the Truck was driven. So this along with the fact that the Truck must be stationary
make it pretty much worthless to me. I asked my salesman about the possibility of turning on the Manual Regen before I bought it and he said they wouldn't do it. So I just
ordered it as an Option. Thanks again for clearing this up for me. Ford should really have some Literature explaining how this works.

Be that as it may, DEF has absolutely nothing to do with the regeneration of the DPF.

of the Exhaust to approx 800 degrees to burn the Soot off and clean the (DPF) Diesel Particulate Filter?

Plus, DEF is injected downstream of the DPF, into the SCR catalyst which is behind the DPF.

But, that has nothing to do with DPF regeneration.
And, it would be a miniscule amount extra, not enough to make the DEF level gauge drop during that process.

You can only do a manual regen when the DPF filter is 100% full, you will have the option on the DPF Status screen.
Yes it has to be parked, thats what a manual regen is.. a static regen.
Don't be in a garage, and don't be parked beside anyone or have dry grass or anything under you! It takes approximately 30 minutes and the exhaust coming out is very hot. RPMs sit at 2k and your fan screams. Don't touch the arrow keys away from the screen or it cancels it, at least with my 19 it did.
I think I understand your intentions when paying the extra for the option but it's definitely not what you thought it was.
Real question is on your new truck is why do a manual regen?
it's brand new. My 19 I didn't turn on the ocr screens until 25k miles. Nice to just let the truck just do its thing and not worry about it.
In my opinion it's nice to do a full manual regen maybe once every 5 or 10k miles to get a nice thorough clean of the dpf filter.
