If you don’t know the acronyms, then this thread is not for you. If you do know, but are going to suggest deleting, then again, not for you.

My 2015 F350 with 125,000 miles needs a new DPF. Of course it, the SCR, and the DOC are all one unit. I can get a remanufactured one for $3,000 while new will be $4,500 or more.

Which should I get?

If you have an MVA due to HBP you will appreciate the DOC. JMHO

For those of us thinking WTF, and feeling somewhat marginalized/reduced to spectating in this thread, here's a cheat sheet, I think...

Thank you, nhracecraft.

When I fought this battle it all came down to what warranty was attached to each alternative and ultimately the price difference. I decided on a new one. But it really depends on factors that matter to you. Downtime is a huge issue for my use.

Try checking Craigslist. Here is an example. https://inlandempire.craigslis...ckup/7457915092.html
People sell these when deleting, as you know.

I would agree warranty would be a consideration as well as how long you intend to keep the truck.

The reman has a 1 year unlimited mileage warranty, while the new one has a 2 year unlimited mileage warranty. I plan to keep the truck. I still need it to tow the boat and 5th wheel.

Ford actually extended the warranty on the DPF to 11 years or 120,000 miles for 2015-2016 Super Duty trucks built in Kentucky that show a P2002 code. I just missed it on the mileage. They also extended the warranty on the DEF pump/heater, so I'll be getting my money back on that which was done at 50,000 miles and withing the extended warranty period.

For those that seem to be, DEF - diesel exhuast fluid.

Both emmissions issues left me stuck with our 5th wheel unable to go more than 50mph. This last time, the truck stopped running completely on US1 between Homestead and Key Largo, succesfully blocking southbound traffic to the Keys on a Saturday afternoon during spring break for a few minutes. Somehow, my son and I were able to push the 23,000lb combined rig enough to allow traffic to squeeze by. The third vehicle through was a dually. He hooked a chain up to us and got us completely off the road.

What's with the attitude? It's off-putting and completely unwarranted.

You carry a UB-21 Schnauzer with a Gnab silencer. That's KGB. You prefer an H&K over an A.K. Your surveillance technique is NSA. Your ID is CIA. You received your Ph.D. at NYU. Traded in your GTO for a BMW. You listen to CDs by R.E.M. and STP. And you'd like to see J.F.K. in his BVDs, getting down with O.P.P. And you probably put the toilet paper back on the roll with the paper on the inside.

For the difference in cost I would go new. I work in the industry, and I am familiar with new plant production of these items, and with remanufacturing plants. Reman is a done on a shoestring budget by service organizations, not production. Their process controls are much less stringent than production. This goes for just about everything.

Thank you. New it is. I’m having trouble understanding how it can be remanufactured without cutting it apart then welding it back together. I don’t believe the DPF can be cleaned with the DOC upstream without ruining the DOC.

Slight thread drift, does you Ford have the manual regeneration option and if so, has it worked well?

I haven't seen a Ford aftertreatment system up close, but all the ones I am familiar with are made in separate sections for the DOC, DPF, and SCR, then stacked and held together with V-band clamps. Before assembly, each substrate is pressed into its section and then the can is crimped to hold the substrate. Sort of like loading ammo. The whole thing can be disassembled into its sections and the DPF section can be cleaned in a special machine a special machine.

If Ford uses a single can with everything in it, then I don't know exactly how they do it.

Have you considered deleting it?

ETA, why are you against deleting it?

There are separate housings for the DOC, SCR, and DPF that are welded together into one unit. No clamps.

I’m not, but Canada is a long way from Florida.
