my F 250 super duty truck has 115,000 km and has been at the dealer 4 times with particulate filter problems, now they said i would need a new particulate filter and catalytic converter since its all in one unit. My 2011 F350 super duty had the same numerous problems since DEF was introduced, Any quick fix or does anyone else have the same issues ?

Apparently all 3 major truck manufacturers have the same problems and the problems stem from when they introduced the DEF additive to burn off the soot caught in the particulate filter. The dealers don't tell you when you purchase these expensive trucks that they should be driven for long hauls under load in order to bring temperature to desired levels for the soot to be burnt off in the particulate filter. These units were not designed for short runs because the soot will be crystallized in the particulate filter with the DEF fuel, thus plugging and fracturing the filter. This tight pollution controls were set by government's and not well thought out by governments nor dealers before coming out with a good reliable system and we the consumer pay's and pay's through the nose for trucks that should be reliable for the money we put out. I feel that WE initiate a class action suit against the Government and the dealers for full compensation for repairs at no cost to the consumer until a more reliable system is designed and installed to all customers that experiencing these problems.

welcome.

Any quick fix? Yes trade it in, delete it, or pay the dealer.

Is anyone else having these issues?

@manitoulin lets try not to spam the forum with your class action lawsuit... when you start it share a link to the filing.

Hello manitoulin and welcome to the forum from N.E. Indiana!! It seems that your truck is being driven a decent amount with that many km's on a 20+ truck! Not sure why you would have a DPF problem! My 2016 only has 75k miles on it but, haven't had any issues with the DPF. Unless you do a lot of short runs per day! Good luck with your issue!

thanks TKR
my truck is a 2019 and the problem is using the DEF diesel exhaust fuel that it does not do the job as designed and the particulate filter micron size is not the adequate size. That's my view.

I'm getting the feeling you do not know how the exhaust filter and SCR catalyst work. I am also getting the feeling the person working on your truck at the dealer doesn't either.

Yeah the not using the correct names of the DEF and misunderstanding on what it is doing isn't boding well for us thinking you have any idea what you are talking about OP. As far as class action lawsuits go, I'm not sure what hate worse, the government or a bunch of people getting together for a class action lawsuit to MAYBE end up with $50 dollars after years and years of litigation (which is also a waste of funds).

Suit settles for $500m! Lawyers get 200m, I get a check in 5 years for $23.15

No the DEF is the diesel exhaust fuel in a separate tank that is used to fire up and clean the DPF diesel particulate filter, it is known that the DEF after a long period of time rather than burning the soot in the DPF it actually chrystalizes the soot thus plugging the DPF and eventually cracking the filter and the whole unit with the catalytic converter has to be replaced as they are one sealed unit at a cost $8,500.00 Can.

NO DEF is not fuel its 32.5 % urea and the rest is water.

 

[Hydro]

DEF is fertilizer -- water it down and put it on your grass
will make it pretty and green

We side dress 28% on the corn to help it grow

 

[Hydro]

Short runs where the system is not allowed to get to full temperature
and engine oil consumption
are the two main causes I see in the shop for failures

DEF = Diesel Exhaust Fluid

A catalytic converter is not the same as a DPF. They aren’t even made of the same material. If you want to come be a smart *** and “correct” someone, do a 5 second google search first or GTFO.

I know that but they are incased in the same housing check it out .

I was being a bit harsh and I apologize. The DPF does fill up over time and you do have to replace the assembly. The SCR is similar to a catalytic converter, but calling it a cat is not correct.

This link covers how the emissions on the 6.7 works pretty dang well and where the DEF is inserted into the exhaust flow and how a regen works in terms of burning off of the soot capture in the DPF.

No problem Socket, but it's quite frustrating that the exact same thing happened with my 2011, F350 a number of times and now on my F250 as you know these trucks are not cheap and the warrantee is minimal. But yet in comparison if you go and have a window installed in your house you have a lifetime warrantee which is a minimum of 25 years.. I know the window is a fixed unit while a truck is a running object. I think if the automotive industry is really boasting about the vehicles they sell then they should back it with a longer warrantee. I don't know if you are aware but dealers now a day's do not make much money on sales, they make money on service this was echoed to me by a seasoned sales person from a Ford dealer. So are they assembling vehicles with parts knowingly that parts will fail prematurely??

 

[kbnw15]

They don't design them to fail "prematurely", just to fail as soon as the warranty is up and the cost isn't on them. Many of us share your frustration with the emissions bull crap but you definitely need to do a bit more learning on the terminology and how the system actually works. Like Hydro said I've used the leftover DEF I had before parts fell off as a fertilizer in my garden, yard, and even dumped it in my water tank I was using to water my Christmas trees.

I have a 2016 F350 with 50,000 miles and have had zero problems. But, I have been told by several diesel mechanics is that they are meant to be driven hard. That is what they are designed for. Do not drive them on short distances (like you might a gas truck), they do need to get hot to burn off any particulates, etc. Good luck!

 

[keving1449]

What is everyone’s definition of “short run”? When I run 30 highway miles empty, my oil temp runs @198F. Hardly use much def. When I tow @10K lbs, I run @207-214F. I will use @ 1 gal. DEF/400 miles. Are EGTs at highway empty miles enough to prevent soot accumulation in DPF? My lack of DEF usage at no load highway miles suggests either 1) yes, or 2) no, 30-60 miles empty is not far enough, hard enough, or hot enough to prevent clogging DPF. Thoughts?

 

[MrTackett]

Here's what too many people driving a diesel don't seem to understand...ALL driving makes soot accumulate the DPF. When it gets "full", it does a regen. If you are doing short trips all the time, using it as a daily driver and not long trips, you are NEVER going to complete a proper regen. Here's what I do on my '16 F350. I keep my screen on my DPF % screen so I always know how full it is. If you don't have that screen, you need to get FORScan and turn it on (if your truck has it). Mine didn't when I bought it so I had no idea how full it was until it popped up and said it was doing a regen. When mine gets close to being full and I know I'm not going on a trip long enough to do a regen, I hook up FORScan and do a manual regen...just like they do at the dealership and charge you a bunch of money. When using FORSCan to do a manual regen, it checks to see if you are at operating temps and if all is well, it raises the rpms to 2k and starts the regen process. For those that don't know, the regen process is nothing more than dumping extra fuel into the system so raw fuel goes into the DPF causing it to super heat and burn off all the soot. DEF has absolutely nothing to do with that process. Treat your DPF right and there's a good chance you'll never have a issue. Maybe not NEVER, but you'll go a heck of lot longer without having a problem!
