I must say, you have the most first hand knowledges about DPF here. I learned a lot from your videos.
Hi, thanks for watching, and I'm glad that they help you out!
I realize I'm kinda off topic but does anybody know of a good place to watch newly released movies online ?
@Kylo Leonardo I use Flixportal. You can find it on google =)
@Roland Eli Yea, I've been using Flixportal for years myself :D
@Roland Eli thanks, signed up and it seems to work :D I really appreciate it!!
Thanks for the video. I watched and enjoyed every single one.
Awesome, thank you!
Absolutely fascinating learning about the complexities of a modern diesel. Thanks for your efforts. Regards
Hi, thanks for watching and I'm glad you are getting something out of them!
Thank you for making awesome videos man
Hi, I'm glad you like them!
Nice video.
Thanks! :-)
“Not getting that close” with the pressure washer. HAHAHA as he’s two inches away with 2000 psi.
hey Steven, another great video... I'm sure alot of people would really like to see a video of how "you" would go about cleaning a dpf installed on the car, especially me.. because your videos go in depth and you explain everything properly and clearly.
Hi, thanks! A lot of folk want that kind of video, starting from error code / ash level, then to removal and cleaning and re-installation, and then finally a 2nd ash reading from the diagnostic tool. It would be a bit rude if I didn't do one!
@@StevenBTuner That would be awesome to have on a video. I have e91 2007 year with m47 engine inside. It ss working good...but (there is always but) it is burning oil...aprox 2l on 10 000 km...seems oil rings. I was thinking to tackle dpf cleaning myself, but couldn't find proper video with all of the details needed for some diy. And btw your videos are awesome and very well made. Cheers and keep up with good work :)
Hi, video coming soon! :-) That's a lot of oil to get past the oil rings, unless your engine has a very high mileage - are you sure it isn't the turbo, or the rocker cover or head gasket?
Turbo was first thing to check, I had a little bit of oil inside intercooler so turbo was sent to specialist to be rebuild (also he cleaned dpf). There are no oil leaks outside the engine so my mechanic concluded that oil rings are not good. I am not sure for mileage...for sure it is not correct because in Serbia majority of imported cars have incorrect mileage. Beside oil problem car is good condition, no rust, interior is really preserved so I am thinking the correct mileage is around 300k km...that is just me guessing :)
Hi steven B. Tuner thanks for making awesome video. What about the pressure withstand capacity of DPF substrate.
Hi, the silicon carbide material itself is super tough and is not even marked by 140bar pressure at point blank range.
Use a karcher with a vario lance, most of them have one. You can wind down the pressure to suit
Steven thank you for these dpf cleaning videos. Is there a pressure wash psi that would both clean the dpf and not damage it?
Hi, thanks for watching! I would say that there is always a risk with this kind of cleaning even if you do it very carefully, and not get too close, and it is not really safe at all for DPFs made after 2010. I now prefer a chemical clean, like the one shown here: ua-cam.com/video/LE1boZ3fhLg/v-deo.html
Is parts cleaner OK for DPF's ? I've been using degreaser as a pre wash but wondered about parts cleaner. Love your work!
Hi, degreaser is perfect for oily soot if there is any. You'd have to look up the ingredients to make a good decision about how safe it is for your environment. There is no need to use substances that burn or explode when you don't have to.
Best way to clean it is, "Add 200ml Harpic + 1 cup of detergent mixed in 2 litres of water and keep it soaked at least 1-2 hours and then wash it with pressurised water. dry it with compressed air before to reinstall it 👍🏾"
Thanks for sharing your method!
Great video I was wondering what the ratio is between drain cleaner(LYE) AND water is
Hi, it is not critical, but I started with 200 grams in 1 liter of water, and then repeat until no more black gunk comes out.
I'd love to see you making a heater core series. That thing keeps clogging up. People flush it with citric acid, special cooling system flush, etc. Are there any alternatives?
Hi, thanks for watching! I'll add it to the list! :-)
Love your dpf videos and this is very interesting but I have one concern... since the filter was cut into pieces don't you think that would effect the overall structure integrity Of the filter elements, glue etc? Maybe less damge would be done if the filter was intact? Would love to know what you think. Thanks for the videos!
Hi, thanks for watching, and for bringing up a very valid point! If I end up with a DPF that is no good for anything else, then a full-size test will be done. The important thing to note however is that almost all DPFs now have integrated catalysts, and a pressure washer will definitely ruin them.
@@StevenBTuner thanks for the reply! The integrated catalyst you speak of.. what year did they start including that? For example I have a 2008 6.7 cummins. Thanks!
@@thomasglace6999 Hi, 2008 was in the transition period so it really depends on local laws and model release cycles. Sometimes you can tell by looking at the housing (or a diagram of it) and if there is a temperature sensor one third of the way along it, then there is more than just the DPF ceramic material in there.
Hi if the DPF clean like u showd one video , dpf clean after fit on the car dose it need re generation ??? Or just start the car warm up nd test drive !
Hi, thanks for watching! There should be no black soot left in the filter, so no forced regeneration is required. Depending on the car, you may need to tell the ECU that there is a new DPF installed (usually only for cars built before 2010).
How about cleaning them in a specialized or computerized machine like i did for my mazda 6?
Hi, that is the perfect way to do it.
Hi just discovered the channel, really intresting videos.
What do you think about hydrogen washing to clean Dpf and Engine?
Hi, glad you like the channel! Are you referring to a specific product or do you mean hydrogen gas or maybe hydrogen peroxide?
@@StevenBTuner Yes the HHO by electrolysis, there are some videos about.
They put a tube in the intake and rev to about 1500 rpm in neutral for some hours (generally 2), than detach the tube and a run on street at high rpm to heat up and burn residues. They claim to clean Dpf, injectors and valves.
Seems a little too simple without taking anything apart?
Hi, it could be useful for cleaning the intake system and valves as the process removes carbon (soot). However, it's not going to do anything to clean out the end-of-life ash deposits from a DPF, so a chemical clean is still needed when the DPF gets clogged.
Also, how about backflushing the DPF using compressed air? You could get to each channel separately (if you cut the filter housing and then weld it back together) and most compressors do only 8 or 10 bar of pressure, so that wouldn't be that damaging I guess.
Hi, that kind of method works great for truck and bus filters that are designed for easy cleaning, and the compressed air is used after an overnight bake in an industrial oven.
I wonder if there isn't a risk of plugging up the filter bu forcing particulates to migrate further into the ceramic material.
It is generally a pretty bad idea, but if you did do it, you would only back-flush the filter so that the soot was forced out the way it went in.
So don't hold the pressure washer nozzle very close to what you're washing , especially not for an extended period of time. The lessons learned here can be applied to most things you'd want to pressure wash
Hi, thanks for watching! A lot of DPFs are very enclosed in their housing with only a 2 - 3 inch inlet pipe - which makes knowing how far away the jet is, and what is being pointed at pretty challenging - especially with water and gunk flying straight back at you. For that reason I still prefer the 2 stage chemical cleaning featured in my other video: ua-cam.com/video/LE1boZ3fhLg/v-deo.html
I pressure washed my dpf in the car wash. I used the low pressure at the beginning and it seems to be cleaning it. Then I used the high pressure and some particles came out of the exhaust end and I stopped right away. I hope I didn't do much damage. I'll just re install it and see where we end up with
You must clean it with compressed air after washing 👍🏾
I like how he is experimenting on cuted on pieces loose and externaly broken DPF to begin with and talking about pushed back insulation and loose silicone)))))
Washed away platinum is a hit of a day))
I was going to say something similar. Because by cutting it into smaller pieces makes it weaker. I'm not as compact. But I get the general idea of what his on about👍🏿
Hey mate. Love your videos!! I have a question about just a Peugeot 307 1.6 HDI DPF
I've got an app for just this car called FAP, it's telling me loads of info and my filter is good for now. But one reading in the app is "Deposits in FAP" and the number is 122 grams, slowly rising. Now what does this mean? My car does around 300 km between every regen
Thanks again for great videos
Hi, thanks for watching and I'm glad you like the vids! If that 'deposits' number is that high just after a regen, then I would say that your filter is getting quite clogged up with ash. Has your car done more than 200,000kms? Also, 300kms between regens sounds very low too, which indicates that there is less and less room in the filter for the soot to accumulate between active regeneration cycles.
@@StevenBTuner Hi
Ok so a manual cleaning might be in it's place. No "deposits in FAP" doesn't get to zero after a regen, so I think that number is what's left and can't get rid of. But a manual cleaning seems pretty straight forward actually, not the first time I've been under a car so I'll think I manage that
Hi, if the filter isn't too painful to remove and re-install then a few hours with a few nasty chemicals will have it back to as-new condition!
Hey mate. So the washing of my dpf is now a done deal. Really not much soot so the regen must be working. Loads of ash thou, which is now gone. I used oxalic acid in i aluminium wheel cleaner, 4 liters. Soaked for 2 hours, flushed it with 4 liters of boiling water and then loads and loads loads of cold water in a backflush while shaking the filter. Eventually all that came out was clean water. F*cked up a little bit by forgetting the gasket while putting it all together, so i had to tear it all apart again haha. Now it's showing 0 g of deposits in FAP, and the acceleration is better. Thx for the help mate!!!!
Awesome! Thanks for sharing your experience!
hello Steve: I have an SL63 AMG 2011. four cats totally clogged. i remove entire pipe ten feet one piece long... Do i pour hot diluted sodium hydroxide pellets food grade, and let sit for one hour? Any suggestions would be very helpful... Thanks much..
Hi, if it oil clogging caused by a blown or leaking turbo (for example) then sodium hydroxide should loosen it all up for sure. I haven't done exactly that before so I can't recommend any quantities. I suspect some agitation every 15 minutes will help too. I hope you'll report back about how it goes!
@@StevenBTuner thank you. The 4 cats are clogged after normal driving 265,000 miles. Nothing broken.
Hi, it will be interesting to see what comes out. I would hang up the pipes and let them dry out for a couple of days after the cleaning to make sure that there isn't a lot of water being turned to steam when the engine starts up - and even then 10 minutes at idle might be a good idea before driving. It will be an experiment for sure, but might be one that is worthwhile compared to the normal 'fix' which is to buy new units.
@@StevenBTuner i removed all four sensors out sprayed ten cans of PDF cleaner made in germany product , it cleaned it a bit, but they are so clogged that it was a waste of time and money..
Hi, those kinds of products are more of a servicing type thing - they can help if you do them once every year or two.
Hi Steven, What about using an oven cleaner as available at any grocery store?
Hi, thanks for watching and for the great suggestion! Oven cleaner is similar to the drain cleaner/caustic soda that I use in a couple of my other vids, so it will probably work great as a 'pre-wash' to remove any oil and oily soot ready for the main acid based wash.
What chemicals use to clean the DPF?
Hi, I have another video where I show the full cleaning process: ua-cam.com/video/LE1boZ3fhLg/v-deo.html
Why is the filter orange in the middle? When I washed my filter a bit of orange/light brown came out. I used alcohol and a low pressure water beam.
Hi, thanks for watching! The orange/red is ash residue, which was left over from my previous video where I hit this piece of filter with the gas torch. A few minutes with the gas torch was enough to remove all of the black soot, but it wasn't enough to remove the ash residue. The different shades of ash depend on what it is made from - more red is probably more iron oxide (from the iron/steel in the engine), and more of a white shade probably indicates more phosphates/sulfates (from engine oil).
@@StevenBTuner Thank you very much! I was afraid of having flushed out part of the filter :) Great videos for DIY cleaning your filter. They saved me some time and gave me a few ideas on how to clean my DPF.
Funny I’ve cleaned my filters on my truck three times with high pressure water and did not damage them . Every 200 thousand miles
Hi, thanks for watching! It is a bit different with a truck as you can get good access to everything. With a lot of cars the filter is only accessible via a strangely angled pipe, so it is impossible to evenly spray the ceramic or even see how close you are or what kind of job you are doing - so the danger of spraying too much on the weaker adhesive material is much greater.
@@StevenBTuner whos cleaning the dpf while its still in the car
for a start why would you go closer when washing also use lower pressure washer never messed one up yet ...when you add fluid let leave it soaking for ten hours then use washer to clean it out will come out easy the soaking in the fluid would have broken it all down so you do not need to go mad and up close with washer it will get all the shite out and bingo nice and clean
Hi, not all DPFs allow you to see easily where you are cleaning - so unintentional damage is possible, and you will definitely damage the DOC if you send high pressure into the engine side of the DPF housing.
I was planing to wash it with a small pressure washer ( dont have much pressure), but now I will just use the garden hose with pressure head😂
If you have done the 2 stage chemical wash (from my other vid) then rinsing with water mixed with some dishwashing liquid will clear out any chemical residue well enough.
Hello Steve, I have a Citroen C4 PIcasso from 2007, the dpf is 400%, a new dpf is 170euros and a clean 150,what should I choose? thanks indavance
Hi, if it is a genuine Citroen DPF then it is an easy choice, but if it is a re-manufactured or copy part then it may be made with less than OEM quality materials, so a clean of your original filter can be a better long term deal.
@@StevenBTuner thanks for the reply,much appreciated, what I found is a no name spare, I'll try a clean by closing one end of the dpf, fill it with concentrated wheel cleaner and let is soak for 24 hours, than wash out. If that doe a bed job I'll replace it,tbd with which part.
Hi, if you're ok with DIY then you can see my whole process in the video "The No Damage DIY DPF Clean". You don't want to leave most acids too long as they will eat the steel / stainless steel.
Damn i wish i saw this video earlier😭.I ended up buying new dpf😂
Hi, good knowledge for next time!
I feel your pain.
I'm very sorry for you... Can you tell what was the model of the car and what was the price of the new DPF you replace?
So far it seems that all those workshops that use special pressure washing cabinets are actually doing more harm than good, while simultaneously claiming that cleaning a dpf with acid or drain cleaner is going to destroy the filter.
Hi, there are a few ways that professional companies clean the filters, and the 'high pressure / low flow' method works well too.
another way if the DPF is to boil water an stir in a small box baking soda-pour it in the DPF /it cleans the inside of car radiators-do it twice an then flush with clear water/should work great on DPF too/plug the end of pipe as you did/it takes rust-slime an griddy stuff out of radiators/an its cheap/but do it twice-you done have to buy that other stuff/thanks much
Hi, thanks for the suggestion - I will certainly add it to the list of methods to test!
@@StevenBTuner - Don't try it inside the Radiator please
I do loads with a pressure washer never had an issue 🤷♂️
Hi, if it is done at a bit of a distance and carefully to avoid the ceramic glue between modules, and only done to back-wash the filter then it can definitely work. The problem can be where you can't see what you are doing due to bends in the exhaust pipe etc. The other thing to avoid is hitting the catalyst material with high pressure as you will rip the precious metals off and send them down the drain!
Mate what did you film that with!!!! A toaster 🤷♂️
Not sure what you mean - it should be good quality if you have your youtube settings set to 4K playback.
I have destroyed one like this. Audi A3 Sedan limousine. Don't use hi pressure
Hi, that's my feeling too. I would recommend a much safer chemical clean like: ua-cam.com/video/LE1boZ3fhLg/v-deo.html
I usually just wash My exaust By putting in a water hose in it with a running engine
Hi, thanks for watching, and for sharing your method! The risk with that method is that if any water gets trapped in a blocked channel then it could instantly turn to steam and cause a crack in the ceramic. What kind of water flow and engine rpm are you using?
Steven B. Tuner i dont know the pressure exactly but basically just regular gardening hose pressure. Basically the pressure that it is pouring out of the hose like from a tap. If i am not mistaken 7-10liters a minute i am pouring. RPMs at idle and once in a while i accelerate until 2.5 - 3k rpm
@@davisliepins1380 I can't believe this method would work whatsoever, not without looking at the dpf internally, refitting, using your garden hose method, then pulling dpf out again to inspect
Did I just ruin my dpf 🤣
You'll have to see how it behaves...
Why can’t you blow it out with a air hose
Hi, thanks for watching! Ash removal using air pressure is used after a DPF has been heated for 8 hours in a high temperature oven. Without the heating to break down the ash it is much too stuck on to remove just with air.
@@StevenBTuner ok thanks
It would have been fine if you stayed back a little more
Hi, it is certainly a possibility depending on the design of the DPF casing.
Ridiculous that we have to fix something that shouldn't be on the car in the first place... I rather remove the dpf and egr and have a healthy engine without problems
