I was wondering if anyone has ever had their DPF serviced. If so is this recommended and what do they do?

 

the word is that around 150,000 miles it needs to be replaced or cleaned.. cleaned means heating to burn off the residue and some kind of wash. haven't seen any refurb units show at the typical parts houses yet.

doubt any of us can do this ourselves (heat & clean)

I was wondering about this... can't one simply take an air hose and blast some (if not most) of the ash out?

 

no.. it is stuck in the filter portion.. the filter element is very fine to capture the smoke particles.

its like the tar that builds up on a baking sheet used over and over in the oven. the stuff becomes baked on. you have to heat it with a higher heat and wash the tar off with something.

We are in trucking business and they do make a machine to clean DPF's. However, the one we are looking at cost a little over $ 100,000. They say they will be charging us like $ 800 or so to clean one, so since we have 120 trucks we will be purchasing one of these once our trucks hit the 350-400,000 range and start to need cleaning.

 

Hmmm.... just as I suspected... it's cheaper to DPF delete it than to clean it once it comes off

 

How much does it cost to do the delete? How many people have seen issues caused by the delete?

 

a couple hundred for exhaust pipe changes
and some few hundred dollars more for the programmer to turn off the regens the computer will force..

as an example, Spartan Diesel systems kit is about $1500 total. on sale for $1300 sometimes.

others are comparable.
Some dealers are very particular, and its a mod that can affect the engine performance (partan top is 310 rear wheel hp additional over stock)..
that could cause engine, tranny, suspension, etc kinds of troubles.. so being particular, they will notice and mark your vehicle as no longer warranted.

other dealers sell/install these as add ons and make money.. and support them (somehow)..

on the 6.0s there seemed to be a lack of extra in the engine design and many pumped up by turner truck blew head gaskets..
we haven't seen that on 6.4s tho.... but there are potential problems.. and I stress 'potential'.. many of us haven't seen any problems.

but spartan has sold less than 2000 units if I read their forums correctly.. not a big sample set.. compared to a million superdutys.(at least)

If you prefer to stay stock, what is the cost to replace the filter instaed of having it cleaned?

 

I can't find it right now.. but $1500-2000 as I recall.

and currently there is no general purpose 'cleaning' available. and no aftermarket DPF part from autozone, etc. so there really isn't a choice

I think those DPF-R's are going for $400. It doesn't 'tune' the PCM per-se...it supposedly only modifies the stock tune to clear out the DPF mechanism versus completely replacing the existing tune if I'm correctly reading/understanding how it works.

I read somewhere (I forgot) that you have to reset some ECM parameter after cleaning a DPF so it will recalibrate something to deal with regens. What I don't get is why would it care? It'll just take a clean DPF longer to fill up versus one that's almost plugged up with ash--Sort of like emptying out and trying to reuse a vacuum cleaner bag that I just fouled up with drywall dust versus getting a new bag. I'd think distance between regens should simply increase afterwards.

 

I would suspect that if someone was worried about there warranty, they would let the dealer deal with the dpf problems! After warranty, if a problem arose, than you could delete away and not worry about the dealer. PPL need too remember, these trucks are rated far less than what they are capable of, so ford has a cushion, so they dont do alot of warranty work! You Tune, that is a chance You take on YOUR $10,000 engine repair bill!

 

The dpf will fill completely in a couple thousand miles. Ford has a failsafe regen around 650 miles. If you leav it on, you must clean it (regen). If you take it off, you must STOP the regen. The computer cannot tell it s not installed.

It's still $10,000 after warranty is over.. Someone on another topic said he was negotiating for $12,700.

I have a tuner, so I am rolling the dice.

I guess I was saying, you can choose too eat it while the truck was supposed to be under warranty, or you could wait and keep your warranty. No matter what after warranty you pay, so you may as well play!
