Hello Steven, we want more videos from you and the BMW, it doesn't matter which subject!!
Man this guy is hilarious lol. My favourite channel
Hi, thanks for watching! What is your favorite part of the video?
Best channel out there !!!! Greetings from Belgium !
Thanks, and greeting from your neighbour up the road a bit in Denmark!
Hello Steven. Miloš from Serbia here. I have just started a DPF cleaning service. Thank you for sharing your experiments and results with us! I would love to see more. You give great insight.
A great service to provide for the diesel owners out there! What type of cleaning method are you providing? Oven cleaning, chemical, reverse flushing or ultrasonic?
Steve, this channel deserves million subscribers!
Right kind of humour, informative and extremely useful.
That plutonium joke in the other video ...I spat coffee all over my keyboard :)
Thanks!
I have now cleaned both my VW and my wife's BMW with your chemical & acid clean recipe it worked fantastically Thank you for sharing
Great work!
great video steve
Thanks!
Steven, I'm loving your series and your approach to testing the different processes and chemicals on DPF cleaning.
Can you PLEASE do a study on whether there's any effectiveness difference between the iron based and cerium based soot cleaning additives?
Thanks - a great idea for some testing!
These kind of experiments are awesome!
Hey btw! Maybe you remember me from the comments under your video about cleaning the DPF with chemicals (HCl and NaOH). It's been 22.000 km since the clean, the error has come back but in reality everything is actually fine. My 120d has returned to being fuel efficient and regens occur every ~200km without a noticeable increase in fuel consumption. Not bad for one that has been used for 391.000 km :D A.K.A. a succes as far as I'm concerned!
Hi, thanks for the update! What is the error message you are getting? I can't remember if your car needed to be told it had a new DPF fitted or not.
@@StevenBTuner it did! I went to the mechanic I go to for these kind of things. He reset it and the error stayed away for a while.
It says that the backpressure is too high. But if I check it, it never exceeds 130mPa. After regen it goes below 50mPa (I believe, I haven't checked in a really long time. It's probably even lower). So I'm not really bothered by the values (Y)
Ciao Steven, ti ho scoperto tramite un video di un ragazzo che puliva il DPF nominando te, così ho iniziato a guardare i tuoi video anche se non parlo inglese, aiutandomi con un traduttore. Complimenti per le spiegazioni, mi hai risolto un paio di dubbi. Grazie
Ciao, grazie per la visione! Nelle impostazioni di youtube scegli di visualizzare i sottotitoli in italiano.
Ok grazie
for doing the test with an industrial ultrasonic tank, boiling water and dishwasher tablets.
on the other hand it is necessary to ensure that the filter is perfectly filled with water to avoid that the vibrations are perfectly transmitted. (water is not compressible, air is)
Good point! Something like dishwasher tablets could work very well.
Hi Steven, Appreciate all the videos, very useful and science based information which will save a lot of money for a lot of people. One general question: at what sort of mileage would you expect ash build up to start be a problem in a dpf? I have the very common 1.6 multijet diesel in a Suzuki with no engine problems that I'm aware of and used 90% of the time for short journeys. Experiencing gradually reducing fuel economy which doesn't improve much anymore after instigating passive regen on motorway. Car has done 58000 miles only.
Hi, thanks for watching! I wouldn't expect ash to be a huge problem at that mileage unless your car was burning a lot of oil, or if the car had been serviced with the incorrect (non low ash) oil. Short journeys are a problem for modern vehicles as there isn't enough heat in the DPF for passive regeneration to happen, and there aren't the right conditions for an active regeneration to be started or finished. Short journeys also allow more oily soot to form in the EGR valve and intake system, so you can get a bit of a vicious cycle going on where one issue causes another. I would recommend attaching a good OBDII code reader to your car like the Autel AP200, so you can see if any system has reached failure point. If there are no errors, then it could be time for intake system to get a full clean.
Hi Steve. Love your videos and channel.
As a result of your videos and research I finally removed my own dpf and used your dishwasher tab method, it work like a dream!!
I have been having ongoing issues for 2 years now, and found some strange when I had my dpf on the bench.
Someone has drilled 2 x 8mm holes right through the dpf filter section. I’ve wonder why my soot mass reading jump around on diagnostics. I assume these holes would effect the pressure readings. Could this be the cause of my regeneration cycle randomly not working from time to time? Have you ever seen or heard of this before
Thanks, keep up the great videos 👍
Paul
Hi, small holes like that could have been drilled like that as a way to get past a DPF error light or regeneration issue, rather than fix the underlying fault. There has been a lot of misunderstanding about DPF issues throughout the years, and often by mechanics who have not kept their training up-to-date.
Greetings Steven,
Another great video. When can we expect the complete test with the big ultrasonic cleaner?
Hi, thanks! I've got the DPF, I've got the machine, I just need a bit of spare time - and the test will proceed!
@@StevenBTuner Thank you for the reply. Hope you find the needed time soon as I am sure I am not the only one eager to see the results.
Hi Steve liked your videos on cleaning the cat specially the nine test one have you tried oven cleaner on any of the samples yet ie Mr muscle could you please keep up the good work
Hi, oven cleaner should work great for the first stage if you can force it to go all the way into the channels. The sodium hydroxide granules probably work out a lot cheaper though.

hello Steve, apparently there is a certain frequency at which the filter of the DPF gets cleaned without affecting the protection surface that the filter is treated that has to remain un-affected.
My findings are that the detrimental frequencies would be 20-25 kHz. All other higher frequencies are better tolerated by the filter..
That's some good information to know!
Relating to DPF only in that I''m looking to test the DPF pressure sensor out of the car
Very nice idea for a test! :) it would be nice to know how big the small one was and how big the bigger one is. (Tank volume in liters)
Thanks for your answer in advance! :)
Hi, thanks for watching! The small one only holds 1 liter, and the large one is advertised as 35 liters.
@@StevenBTuner thinks for your quick answer! Keep up the great content!
Hi Steven. I'm writing to you from Argentina. Very interesting topic about how to clean the dbf. I was wondering if you finally tryed with the bigger ultrasonic cleanner. I was thinking about taking of the dbf, fill it with some ultrasonic cleaning fluid and close it from both sides and then sink it in an ultrasonic cleanner. I think that the ultrasonic power can travel through materials but I do not know how much of that power is going to be absored by the metal. The main idea is to have the same effect that you could get at the surface but inside of the dbf. Make sense? 😅
Hi, ultrasonic cleaning is how some professional DPF cleaning companies do it, so it definitely can work. There is probably a best fluid to use, but I think you will get good results even with water. I'd love to hear how it goes!
Hello steven
Can it also be used for gasoline cars ,?
Hi, some of the comments are from folk who have done it to petrol catalytic converters, and it has worked well.
Have you done the video with the bigger ultrasonic cleaner?
Not yet - it is on the list!
@@StevenBTuner Must be a hell of a long list since its been over a year!
I have a question.
How are the stability, internal carbonization and external emissions, engines burning alternative fuels, gas, methanol and others, in the world, you already have experience from these destinations?
Hi, I'm not sure I fully understand your question. Alternative fuels aren't used in most place because there is no good infrastructure to deliver them cheaply, or they are too annoying to store. Whether they are good for the engine is a secondary consideration.
My van gives 0.2 opacity in ITV (in my country), MOT in yours and according to the manufacturer's sticker it is 0.1. I see some exhaust smoke at very high revs, above 3000rpm or higher. Not much. Everything seems to be fine according to the scanner. The old owner changed the DPF. Does the DPF have to retain all the smoke? What can I check, I don't know where to continue looking at what the problem is.
Hi, that is not the best indicator as a DPF should not let any soot through at all. That kind of reading usually indicates a crack in the ceramic material. I helped a friend get through the inspection recently by adding a bottle of fuel injector cleaner and two bottles of diesel no smoke additive (all by Liqui-Moly) as well as filling up the tank with premium diesel. The passed the smoke test with no problem. It doesn't fix the DPF issue but at least it will keep you driving for the moment.
@@StevenBTuner Ammm, I hadn't thought about the crack in the ceramic material, maybe. I already tried all kinds of miraculous liquids, go up to 4000 rpms, etc and nothing. Thank you very much.
Do you think cleaning the DPF with a dirt water pump and a mortar box might work? I've seen people use it to clean their intake manifolds and i tried it myself and it did work. You connect the water pump to the intake manifold through a garden hose, fill the box with water and a cleaner and let it circulate for a few hours. So i thought maybe doing the same procedure might also work with a dpf?
Hi, a lot of professional DPF cleaning companies use high pressure / low flow back-flushing as part of their process - so there is no reason why it can't work...
Alright, thank you
Do the video with fhe big ultrasonic cleaner ever came out?
Hi, thanks for asking! I have filmed most of it, but, spoiler alert, the ultrasonic part is a complete failure, so I continue instead with my normal 'no damage' method. I guess the big consumer-grade units just don't have the required punch...
@@StevenBTuner thank you very much for answering Steven! I was thinking about mixing the two chemicals method with the ultrasonic cleaner, using one of those modules that you can attach to anything in the filter Inox body.
Hi I have a question anyone could help i live in NSW Sydney i have a 2019 2.2 turbo diesel mazda cx5 the car was showing dpf warning light the mazda cx5 has been taken 3 times to mazda car workshop dealer they have changed the DPF sensor and checked car all around and they done a full report test. The was repaird but the issue still has come again with the same problem the text day DPF warning light What could it be please.
Hi, they have not been too helpful! Unless your car has over 200,000kms on it, then you can probably rule out ash clogging - so your DPF probably doesn't need any cleaning, it just needs all of the systems to be working well. There are quite a few systems that can stop the DPF from doing its normal regeneration, and it varies a little bit depending on the make/model, but generally you will want to make sure that the turbo is working well and not leaking oil straight into the DPF, the EGR valve needs to be working well, the intake manifold needs to not completely clogged up (if the EGR valve is completely clogged then the intake manifold is too), the glow plugs and glow plug controller need to be working (most cars), and the crankcase ventilation system needs to be working correctly. Phew! Sounds like a lot of stuff, but most of the time you will either get an error code on an OBDII reader, or the visual inspection is not too difficult. Some cars won't regenerate the DPF without a nice 30 minute drive at over 80km/h - so that can be an issue too if you are mostly stuck in traffic.
@@StevenBTuner
It's a mazda cx5 2019 done 55000kms still a baby its still under warranty with mazda but still getting the same issues again and again

@@issasafar1107 Hi, start with getting a good OBDII reader connected and read those error codes. I have had good success with the Autel MaxiAp AP200 with BMW and GM cars, so there is a good chance it will work as well for Mazda too.
Just sell it man, those 2.2 Mazda Skyactive D engines are pure shit. They’re so cheap on the second hand market for a reason. Have you had a look on the whirlpool forums? There’s been a few posts on there about them.

Why no more videos?
More videos coming soon!
hey, no doubt chemicals will be worth using in the ultrasonic cleaner.
If not sure which chemicals are best for melting the red-orange ash like there's no tomorrow - there's a guy with channel on youtube, some "Steven B. Tuner" or something like that :) and that chap has performed exhaustive tests with some surprising winners.
Looking forward to 35 liter ultrasonic video Steven : I believe the mechanical vibrations will extremely amplify the aggressiveness of both dishwasher tabs or 32% HCl whatever you decide to use (both ?). The question is what will happen with the stainless steel basket, main problem being "not all Chinese stainless steel really is a stainless steel".
Maybe lesser concentrations... 1:20 dishwasher tab prewash and 1:10 HCl instead of original 1:10 and 1:4 used in your original videos. I mean ... that youtube bloke Steven's original videos !
Maybe compare both concentrations, 1:4 HCl and 1:10 HCl ? Hmmmm.
All in all, thanks a lot & Cheers
note : didn't mean to use time references to video, this was done automatically by youtube.
Thanks for the great comment! You have identified the problem correctly - acids and cheap ultrasonic cleaners are just not compatible. Fortunately the ultrasonic action does seem to do quite a good job on its own.
Ultrasonic baskets as spare parts ? :) process four DPFs, throw away collapsing basket, replace with new one, process couple of another DPFs... yeah I'm twisted mind.
I'm dreaming about putting DPF into Ultrasonic bath with some HCl or DishWasherTabs, switching that thing on and getting a perfectly clean DPF 45 minutes later when Top Gear episode is over. Actually I wanted to try that since your videos with chemicals were out months ago... Being a gasoline owner and having no big ultrasonic contributed to no real result so far.
Would be blatantly perfect not having to manually wash, pour acid left right and center and generally "physically deal with" DPF for hours and hours... (breaking some glass along the way and potentially cutting couple of fingers off).
Thank you very very very much for sharing your knowledge, experiments and findings with us !
@@lubomirzvolensky3630 All good thinking! I know that some DPF cleaning companies already use ultrasonic cleaning machines - so I guess the real mystery is whether cheap consumer grade machines (cheap 35 liter machines are not THAT cheap...) will also work well enough. With new gasoline cars now having particulate filters too, the same issue with ash build-up will apply to them in a few years.
@@StevenBTuner I don't think gasoline GPF would have identical problems as diesel DPF. I might see couple of reasons :
1) gasoline burns differently than diesel, it doesn't produce nowhere near as much soot (and hopefully ash) == should not clog up GPF the same way as diesels do.
2) gasoline reaches much higher temperatures in exhaust = much quicker regens, achievable much sooner & easier. What's the major diesel regen problem ? Achieving high-enough temperatures, quickly enough : can you regen a diesel during 4-6 mile drive in town ? Hardly. How long will they take when running ? 5 to 10 minutes ? Gasolines will start GPF clean-up processes in shorter time than diesels, and will finish much sooner too.
3) dozen+ years of experience with diesel DPF. Material science and natural progress.
4) much easier to mount gasoline injector + spark plug into GPF and burn fuel directly inside [in front of] GPF. Old diesels try to change engine timing to achieve required conditions, diesel fuel gets into oil ...
5) gasoline not as sensitive as diesel in terms of clean combustion. Fuel & spark, it will burn. Smoking diesel ? Easy. Smoking gasoline ? Hardly ever.
6) gasoline creates more egress pressure in the exhaust system, runs at higher RPMs. Small factor, but still one.
7) gasolines do not have 18.000 mile (30.000km here in mid-Europe) oil change intervals. Almost all diesels do. What a difference in ash production !!!
8) gasoline has excellent cleaning characteristics/abilities. Diesel turbos (VGT), EGRs and intakes are easily cleaned by gasoline. ua-cam.com/video/e6_InfHj_w0/v-deo.html ua-cam.com/video/2wJZimRzKyY/v-deo.html that black "liquid",,, it's a gasoline polluted by carbon.
Hey, what a topic for new video ! Free talk about gasoline and diesel particulate filters, take all the ideas above, add some ... and simply discuss them out loud.
I take no commission :) they are yours for free. Seriously. Maybe invite somebody from the industry to talk it through with you...
What a nice chat we have here :) Cheers for the freaking weekend !
Hi, thanks for the great comments! Since ultra low sulfur diesel fuel is standard now throughout most of the world, the ash in DPFs mostly comes from the engine oil. Even low ash engine oils are going to create some ash because the compounds that form ash are also the compounds that prevent engine wear. I agree with you about the crazy long service intervals not being helpful either - but car manufacturers seem to not care very much at all about how a car lasts once it has passed the standard lease term (I think that they should specify shorter service intervals after 5 years). All the best for the weekend!
Oh man, I just bought 15l ultrasonic cleaner, that's way too small to my DPF. Manual shaking has to be enough
Hi, the 35 liter unit that I bought is just big enough for some car DPFs. The best process that I know of so far is my 2 stage chemical wash featured in this video: ua-cam.com/video/LE1boZ3fhLg/v-deo.html
I also bought a 15 litre model as I spent a ton of time scrubbing oily parts in a washing up bowl and never wanted to do that again. There are plenty of parts you can use the ultrasonics for like injectors and any other greasy/oily/corroded car parts.
Detergent? I’d have used
Hi, a strong detergent can be used as the first stage wash to help remove the oily soot.
Are you not following up with a full size ultrasonic cleaner
Hi, everything is ready!
@@StevenBTuner we want to watch it!!
@@StevenBTuner don't keep us waiting , please !
if only i could get my dpf off .its welded on with rust on all nuts and bolts.
That doesn't make the job very easy! If you can get a sensor to come loose then you could use something like Liqui Moly in place DPF cleaner.
Why you stop posting? :(
Everything is starting up again soon :-)
@@StevenBTuner yay!
Mr Muscle Foam oven cleaner will be nice to test. It seems it makes a lot of controversy in this video ua-cam.com/video/2k8IdyXwGE8/v-deo.html I think it might be the best engine cleaner but some worries about the aluminium corrosion, i would say that the oil breakdown from lubrification will be the possible issue. You might be the best to test this and a great video for sure. Instantly i was thinking about your tests and the ones from Project Farm.
Gotta love the Project Farm! Mr Muscle and other oven cleaners work a lot like sodium hydroxide drain cleaners, so it will be good for dislodging oily soot - just like it does in your oven or fireplace. However it won't be very effective against the ash deposits, so a second stage clean will be required - as seen in my other video: ua-cam.com/video/LE1boZ3fhLg/v-deo.html
@@StevenBTuner Thank you for your reply. I watched almost all your videos...Seeing your videos i was thinking that you might have an opinion if the Mr Muscle or sodium hydroxide can be used in EGR and intake manifold cleaning. In the same way like the carb / egr cleaning ones. Maybe to put in the second stage the acid and this will neutralise the base left. The engine water vapours might eliminate also the leftover and is possible that a small amount to reach also DPF. The video link from my first comment was this guy putting it into intake manifold. I'm intrigued and might work but a lot of people said that is a bad idea mostly to aluminium, second the water after...in small quantities and in short time might work in the same way like you experimented with the debris from DPF and filter without damaging the metals.
@@FlyHighWavesSounds For cleaning EGR valves and intake manifolds when they have been removed from the car, oven cleaners and sodium hydroxide will work great, along with lots of brushing and scrubbing. Rinsing after with lots of water and a bit of washing up liquid will make sure that nothing too nasty is left behind. There are commercially available sprays you can use while everything is still on the car, but all of the loose chunks will end up going through your engine, turbo and into your DPF - which is not perfect...
