How to clean a DPF

[@hookahb8299]

Thanks for the video...I went ahead and did this...First i boiled lots of water, i put the filters in seperate containers big enough to hold each..Then i poured the rolling boiling water in ,and sumerged both..Then after about 20 min i grabbed each filter and lifted them up and back down, swishing the water thru them..This got tons out of the filters..Next i pulled them out after about 45 min...Let them cool a little , and powerwashed them like you did..I did that for about 30 min, being careful to not go to hard and damage them.I then reboiled water and repeated this process the same way, and powerwashed again afterwards..They came super clean, i was very happy with the results .I then put them in the sun to dry..The next day they were reinstalled ,and everything is perfect..I driven about 10,000 miles since then ,and life is good, no problems..

[@firstname6208]

with out proprietary software how do you update the dpf miles in the computer? cleaning is only 1/2 the battle- the light is still on unless you update the module. every pound of diesel has soot in it. years ago it just went into the atmosphere, now we trap it, burn it, spray chems on it, then remove the filter, clean the filter and flush it down the drain into our water supply. besides making several new industries to either delete the dpf or clean it, what has been accomplished with all that crap the epa has mandated! another prime example of the fourth branch of government forcing crony capitalism down our throats.

[@JBFromOZ]

I've recently had a DPF issue on my Mini Countryman, and ended up cutting my filter open, performing a high temperature pyrolytic clean (in our self-cleaning oven no less...) and then pressure wash in the reverse direction as you have shown here. By using the high temperature process first, it made sure all of the unburnt fuel in the filter was already turned to ash, (without chemicals) and making it much easier for the pressure washer to clean the remaining particles clean. thanks for sharing

[@cankofana]

does not that filter already go through higher temperatures in the truck than in the oven?

[@jimbush8325]

Dude, You are the Bomb. Thank you so much for clarifying this. I just did what you said and used my hot-water pressure-washer with a wide-angle tip and cranked back the pressure a bit [it is a 3500psi] to below 2500 or so and started cleaning very carefully. Dam if the whole cap popped right off and a ton of soot can out [They do a lot of short trips around town]. Did a quick Borescope and found no visible evidence of damage. Bought 2 gaskets and reinstalled the sensors. This is the fix. Again thank you so much and my customer loves ya.

How’d it go?

[@jeffwestbrooke279]

I worked at international dealership and I serviced the doc and dpf. we used fsx air machine and I was quite impressed, I thought it did a great job. my opinion was it was stupid we collected the soot from the items then throw the soot in the garage. the soot ends up in the environment anyway. that still has to be way better than removing from water. I also thought EPA was stupid...... how is it illegal to idle more than 5 minutes but somehow good for the environment to run at 1200 rpm for half hour dumping raw fuel in the exhaust? bp and mobile must have designed after treatment system.

[@sstevocamaro]

jeff westbrooke how much do it cost to have DPF cleaned at the dealership? I have a ProStar with the regen system

[@mibars]

It doesn't work like this: Soot is caught by DPF and burned off either during heavy load or when engine enters regen mode. Soot is carbon, it goes into CO2 and flows out of your exhaust as a gas. What stays in the filter is ash - non-burnable solids that pass through your engine and come from oil and fuel additives, engine wear products or even very fine dust particles that make their way through air filter and get stuck in DPF. You get only tiny fraction of ash in your exhaust compared to soot, otherwise your DPF would get filled in no time.

I'm not a tree hugger by any means. But seems kinda silly that we can't have the soot in the air but we can wash the soot out of the filter into the water systems......lol makes perfect sense. Still ended up into the environment just took more steps to get there.......enginering at work. Just my 2 cents

[@TheDieseler]

Jamie Prentice Soot is trapped in the filter and then converted. What you're seeing washed out is Ash. There's a LOT less of it but, you're right, it's not very good for the environment either.

[@firstname6208]

every pound of diesel fuel has pollutants the epa does not like. we used to put them into the air straight away, now we have an entire industry to build computer controlled boxes to trap and incinerate these , but once they are full we wash the "concentrate" down the drain and call that progress.

Never done it before didn't even know what a DPF filter was until a week ago and found another video and how to break it down so that I can clean it and worked out great trucks driving nice and it was extremely dirty I learned a lot from the process appreciate you putting the video out there telling people that there is an alternate way to take care of this problem other than spending one two three thousand dollars so thank you for doing that I'm going to add my own video link to yours and appreciate it.

[@LimousineIndianapol1]

I want to add an update to my previous story and that is that after we change the filter I went on another trip and had more problems with my DPF. My DPF light went on but I was not able to regen at all.I was able to get to a mechanic before it went to level four and he found that all of the sensors were in the wrong position.now that the DPF was cleaned the sensors were receiving information that did not make sense to the information they should be receiving since all sensors were in the wrong positions the data they were receiving was also incorrect.the mechanic was able to move the sensors to the right positions and allowed the truck to go into regen process.I think cleaning the DPF was the catalyst that expose the real underlying problem of the sensors being in the wrong position since all of the sensors were able to receive information due to the unclogged DPF filter now the data that they were receiving did not make sense with the information they should be receiving.the moral to the story is make sure that all of the sensors are in the correct position before digging into more complicated Solutions says there's a good possibility that the DPF system was worked on prior with another owner or mechanic. This mayhelp you reduce your repair cost once you know that the DPF sensors are all in the correct position on the DPF housing.

I don't understand how a DPF saves the environment. If you remove it the particulates fall to the ground, they are heavier than air. If you clean it the particles go down the drain. If you replace it the particles go to the landfill. One way or another it all ends up back to the Earth.

I'm not sure what the substrate of the filter media consists of but I can't see why you couldn't pre-soak the dpf filter in a hot bath mixed with CLR or similar product to soften/loosen the carbon soot buildup then a short rinse with high pressure water. Another option I wondered for older diesels like mine without emissions and EGR is a simple steel mesh air filter like the same one used on the intake side to capture carbon soot particles, then wash it out at every oil change "B" service.

[@firstname6208]

one problem for the backyard mechanics. you still need proprietary software to get in the exhaust management computer and update the clean/replace dpf miles or the light will not go out. also when you reinstall the dpf you need to lead/asbestos wrapped clamp so it will reseal when it gets hot. failure to replace the clamp will give a leak inside the one box. and then you get a dpf pressure diff code. if the code comes up to clean the dpf you can still go 10k-15k miles with the light on. engine will not shut down.

[@firstname6208]

forgot to mention , perform a parked regen before removing the dpf's. when u have the dpf's out write down the dpf serial numbers. you will need those numbers when you update the exh management computer. also inspect the dpf's close. any crack or meltage on the surface of the substrate - they are junk. no core, not reusable. there should be zero, zilch, nada, no soot on the outlet side at all. have a dozen 1/4" fender nuts and 1/4 x3/4" bolts in the tool box because you will need them.

+First Name For Detroit's, this is all true. Like I've written in other comments though, resetting the Ash Accumulator is literally a 1 minute job.

Dpfs on big trucks are hardly a restriction. not like your cat on your car at all. a plugged dpf you will see 1 psi . not enough to cause a reduction in performance by any means. trucks run 30 psi of boost so that's at least 32 psi between exhaust valve and turbo, and then it drops to on average 0.5 -0.7 psi between turbo and aftertreatment.

No problem. Glad to hear that!

[@TRUCKINGTIPSDIY]

check out my video how to clean dpf filter using a vacuum

[@Marcusf250]

Do I need to clear a code using a laptop with the software afterwards, like on some other videos? Or can I just slap them right back in and DPF light should be gone. My Freightliner has 800,000 Miles.

[@TheDieseler]

If the engine light is on because it is requesting an Ash cleaning then it will most likely need to be reset with software. Detroit calls it resetting the Ash Accumulator.

[@easydoz1]

Ask a dealer to reset the Soot Counter. Took three different dealers and a promise to replace it when we had the money...

[@ZafarIqbal-qe2po]

neat - thank you for easy and cost saving method I will try this simple method on my 2011 freightliner - btw do I've to buy new clamps to reinstall the filters or can use the old ones please let me know Thank you 😊

[@1VicentG]

After the clean up .. I have to plugged the truck to a computer or any specific program. I'm asking because I don't have neither of those, just want to know thanks and keep the amazing job

[@Anonymous03100]

what psi compressor to use? how strong? i am about to do this. thanks

[@TheDieseler]

I couldn't give you exact numbers. I'm not sure what the pressure washer I use is rated for. I guess a typical unit that you would use to wash a vehicle.

[@d.j.robinson9424]

Just wondering, wouldn't "DAWN " do a more thorough job..?🤔🤔

[@robertt6430]

Reverse jet wash.. works a treat.

[@jonathangray4262]

In the state of California this is not legal. Also this looks to be a Detroit one box and doing this will void your warranty and could also cause the one box to go bad costing you $10k or more instead of doing it right the first time. Detroit requires you to exchange the filter instead of cleaning them and that goes for any where in the states. The dealers telling you that you need to replace them are getting that info from the manufacturer. I would say the engineers at Detroit know what they are talking about and its probably a good idea to listen.

[@wb2679]

Jonathan Gray what he’s doing is not legal anywhere EPA says soot/ash is not to be released into the environment its to be disposed of properly. I laugh at these types of videos they ppl who do this seem to end up at a dealer later and spend a lot more money than they would if they came in for a proper cleaning

[@paulanderson79]

My first DPF car was a 2001 Peugeot 406 HDi. I've had two others (not Peugeots) since and so far no issues. Possibly just luck??

[@NN-xu6jw]

I think that after this proces of cleaning i think it's the best you have dot put the dpf in a oven are something to dry the water that stil is in the dpf out of it.

[@badbob666]

I use a torpedo heater and blow it through until you see that it's dry you can easily see the difference of where the moisture is the medium will be a different color.

[@youandme2010ify]

How much pressure should be on pressure washer, so can't damaged filters

[@supertrucker1356]

Is there a alternative gasket to use when having to properly seat filters that have been installed improperly? Im going to try and readjust them since i see soot, but want to reuse rings since i just bought them. Is there hvac tape that can act as a new gasket?

[@TheDieseler]

These filters see 1100 degrees. I wouldn't recommend using anything but the seals that are intended for them.

[@MK-yg3go]

thanks so much for the video very helpful . i did the same as the video . after the black ash came out i noticed so brown or dark orange color started coming out also. just asking myself did the filter got damege or some ?????????

[@SalimKhan-gk1fh]

You will get orange coloured particles come out it’s where these DPF filters get redhot trying to regenerate it turns the ash to an orange colour if orange coloured water came out that’s a good sign you are flushing it out!

[@nasseerismael4394]

Hi ,.. Does it need a certain ( psi ) for the water pressure machine ? Cheers

[@ishatpreetnagra671]

I tried cleaning my dpf with water but now truck shows code P2002 which is for DPF efficiency below threshold... Any suggestions for that?

[@lex4758]

Did you let it dry out completely. If you did, maybe you need dealer to do manual regen.

[@j.e.2323]

Dont wet wash a dpf, period. I clean DPFs. The process is as follows: visually inspect the clean side of the dpf. What you're looking for is small cracks in between the cells, shifting ceramic or more than 20 corrupted cells. A very easy way to tell from a visual inspection if your dpf is bad is if there is soot all around the outer diameter of the clean side. If the dpf passes visual, we pin them. Were checking for soot depth. Then we flow them on the fsx table and correspond that reading to the fsx provided spec. After pinning we blow them out, on average a moderately dirty dpf will take 20 minutes. Then we reflow and pin again. If the dpf is still out of spec, we bake them in a kiln for 12 hours. This allows the remaining particulate particles to be broken down and blown out after a second time through the machine. Wet washing a dpf is a highly inefficient way to clean them. Its ceramic...you dont get ceramic wet. It's common sense

[@j.e.2323]

@Bryan Case coffee mugs and DPFs arent even comparable lol. But hey man, thanks for the professional opinion.

[@reaperreaper5098]

Bryan Case Coffee mugs are also coated with glass on the inside and most of the outside. Also, what liquid is being used in FSX's machine and how it's delivered play a huge role. Not a stretch for their specialized machine to safely clean a DPF if pressure washing it doesn't.

[@MrJachacon]

I sent my to a shop who baked twice and still have the check engine light on

[@rubberduckyconvoy2723]

My 2014 Peterbilt 384, Paccar MX13. I have a Check Engine, and I had a light High Exhaust Temperature, and blinks light Stop Engine. So I had that when idling, but when I drive it is ok, automatic regeneration cone on. So I have been to call to Peterbilt shop, I had talked to mechanic, he asked me few questions, it is mileage 415500, it is need to clean DPF. So this is my first time with DPF issue. But I like you do clean a DPF on video. I would like to bring my truck to your hands. But I am living at Middletown, DE

[@GG-ub4ej]

Oleg Vishnevskiy I think he lives in Canada do to the rear license plate and speedometers in other videos. Just thought I should let you know in case your not bonded for 20k to drive there or governed under 65mph.

[@rubberduckyconvoy2723]

G G Excuse me, I do not understand what do you mean.

[@GG-ub4ej]

Oleg Vishnevskiy You said you live in Delaware and want to take your truck to him. To cross the border in a commercial vehicle requires a few things I pointed out.

[@onionpeeling5822]

My truck is in need right now l am going to try to myself .. any more tips about how to take it out ??

[@azimof48]

Mine too. Only if I knew the way to take it out. Let me know if you find out please.

[@gmolina0614]

Abdul Azim is not hard man, i just took my out today. you remove the skirts if you have any and the steps. after that use a 10mm to remove the cover of the box, than remove the clamps from the filters and slide the front one out and do the same thing with the back one. you will HAVE TO but the clamps, the front ones(2 clamps) are sold as a kit with the metal gasket included(2 gaskets) The back ones are a little pricey, maybe 140-160 each, thay are sold reparately. Some people reuse them, you will have to but some sort of sealent if decide not to buy new ones. I recommend you buy new ones.

[@azimof48]

manuel doesn’t seem too complicated. I’ll give it a try this weekend. Thanks for taking your time to reply!

[@TheDieseler]

+manuel Sound advice. I would also recommend new clamps. Leaks will give you further trouble down the road.

[@desvariosdeuncamionero8856]

Remember to write down the filters code, so when you get your dpf system update on the computer you will need them

[@MrFrank1121000]

Do you have to dry them ? Or install them straight after while wet???

[@usdpaulp]

Blow them out w air first.

[@BSbull]

So it's safe to say this would work on my little VW Jetta TDI's DPF?

[@steve5912]

Delete it!! I deleted my TDI

[@joesanchez4895]

Great video 👍thanks for sharing your knowledge!

[@catherineroche2382]

It only worked for about 100nmiles and then had the same problem and had to regen it 4 times before I got it to a shop to get the DPF and DOC filter baked

[@musheghhayrapetyan8982]

inlet side of DPF is fantastic clean. before making this video have you cleaned/wiped inlet side ?

[@TheDieseler]

Mushegh Hayrapetyan I believe there was only a regeneration performed before the cleaning. Regenerations should be ran before cleaning whenever possible. Especially if air cleaning since air cleaners cannot remove Soot.

[@musheghhayrapetyan8982]

I cleaned one dd15 dpf today. My hot water pressure was 45psi and I just used nelson fireman's nozzle instead of pressure washer. I did like in your video. But I tried flow direction also. I think 5 minute one direction and 5 minute opposite direction will give you better results. I saw brown pieces of ash(like little stones) was coming out from both ends.. it took 45 minute until everything came out. After washing I did a test using long wire/rod. measured different areas. I see some spots where half inch hardened ash is packed and did not came out. Overall this method is much better than bake and blow. thank you for posting this video !

[@alexandruvirgil1625]

[@gregallenphoto]

Thumbs up! Thank you for being to the point. Well done!

[@nilayamrathor6014]

What is the pressure of water ? What is the range of pressure that we can use for cleaning?

[@scottrayman5817]

How do you get around the service life monitor that is linked to serial number on some of these filters?

[@redwhiteblueamerica1952]

On the newer trucks would you have to reset the computer after cleaning?..thanks for the video btw

[@TheDieseler]

Yes that's a good point. It would be best to have a shop reset them. Detroit calls it an "Ash Accumulator". Cummins calls it DPF maintenance I believe. I'm sure every manufacturer has their own term for it. It literally only takes a minute to do.

[@doriandorian5651]

TheDieseler Hello sir If i clean it myself and then go shop to reset it.They gonna reset it? Also this way keep cleaning and rolling same dpf, how long u can use original dpf ,. Thank you for your video!

[@sergiyvlasenko4309]

TheDieseler Is it okay to use little bit of dish soap? Don't you think it will remove soot easier?

[@TheDieseler]

+Sergiy Vlasenko I wouldn't risk it. Mostly because it would find its way downstream into the SCR system. In reality though, both it and the DPF rely on chemical reaction to function properly. I wouldn't risk introducing anything like that into them just because of the slim chance it could interfere. There's also the chance it could harm NOX sensors. Cummins has even Incorporated a shield to protect the Outlet NOX sensor from getting soap on it when cleaning the truck.

[@BailinAN]

Hi does this method also apply to Mitsubishi Pajero DPF? Thanks
