DPF Cleaning at Home - 9 Chemicals Tested (Diesel Particulate Filter DIY Ash Cleaning)
ฝัง
- เผยแพร่เมื่อ 30 พ.ค. 2024
- In today’s video we test out 9 chemicals on an end of life, ash clogged diesel particulate filter at home. To do this test I first cut open an old DPF and cut it into small pieces, and then test each piece to see if the chemicals can dissolve the ash build-up. The chemicals tested are: Wynn’s Off Car DPF Cleaner, Drain Cleaner, Swimming Pool Acid, Dishwasher tablets, 32% Vinegar, Acetone based paint thinner, Brake Cleaner, Cola and Alloy Wheel Cleaner. Watch and find out! Please note that these kinds of chemicals are for cleaning a filter that has been removed from a car, and should not be used for cleaning a filter in situ. To see how these chemicals are used in an actual DIY cleaning process once the DPF has been removed from the vehicle, then follow along with this video called "The No Damage DIY DPF Clean": • The Non-Damaging DIY D... Warning: None of these chemicals should ever be added to your fuel tank.

If removing and cleaning your own DPF is something that you are interested in doing, then you can see the whole process in my video called "The No Damage DIY DPF Clean": th-cam.com/video/LE1boZ3fhLg/w-d-xo.html
I know you said the HCL won, but to my eyes the Oxalic Acid Alloy Wheel cleaner was the winner. It removed both the soot and the oil (see soapy foaming action)
@@crocodile2006 Hi, a few folk have used oxalic acid with good results, so either will work well.
hello Steve a lost your message how clean dpf with caustic soda and acig how meny grams
@@user-uw5en4pl9v Hi, the full 2 stage procedure can be found in my other video: th-cam.com/video/LE1boZ3fhLg/w-d-xo.html I use 200 grams of caustic soda granules with 2 liters of water, and when it comes to the acid wash I use 2 liters of 30% strength hydrochloric acid mixed 1:4 with water (8 liters of water). Do lots of shaking if you can, and don't leave the acid in for more than 30 minutes.
Porque' este interface deixou de funcionar no meu Aipad Scarlett sempre funcionou e agora não dá! Atualização que seja feita pelas duas impressas o mais breve possível pois não posso trabalhar em estúdio agradeço a vossa atenção!
I used a hammer drill, chisel, and a 3 inch drill bit. It never clogged again.
Makes the engine last longer too now it can breathe
😂😂😂
Better use dummy CAT CON, problems solved.
Just to be clear to people reading, you can't just do this and expect to drive off in a modern car. It will detect it, throw some codes and go into limp mode. An ECU remap would also be required.
🤣👍
Thank you Steven for creating this video. I have successfully restored a heavily blocked DPF from a Subaru using your Dishwasher Tab/Pool acid technique. Two months later, still working fine with no problems. The original cause of the blockage was sooty oil completely encasing the MAP sensor, and an intake boost leak. The car is running well, with performance and economy significantly improved. Cheers!
That's really great to hear! Sounds like you identified the causes, which should prevent any repeat issues too.
Happy to report the car is still running perfectly after the cleaning process seven months ago. Thanks again. ;)
This video! My MBZ DPF was completely plugged and I totally submerged it in 4 gallons of pool acid in a bucket for a couple hours then sprayed it out with a pressure washer. Came out new. Brand new. Works perfectly $44 total cost. Thank you!!
Well done in tackling this unpleasant job!
That’s a great idea , submerge it.
Thx!!
What was the concentration? Was it an off the shelf premix?
Just discovered your work ,here ,and you are one of the best !
If you aren't a teacher in this life ,this world lose a great opportunity to have some kids well ,,trained,, for this life ! You know how to explain, kind voice , good with details!
Anyway, congrats and keep it running!
Thanks and welcome!
The irony of DPFs is hilarious. Save the environment by filtering out some particulates, while at the same time consuming almost double the fuel and halving the efficiency and life of the engine. Great video though, pretty enlightening. Coke is scary stuff.
There's nothing ironic about the DPF, because its purpose is not to reduce emissions overall, but to reduce the *toxic* emissions by transforming them to essentially non-toxic substances. In that regard it's a marvelous invention, because it reduces toxic and cancer causing emissions with at least over 95% efficiency. Also your double fuel figure is off by a magnitude of two at the minimum. In reality DPF only increases fuel consumption by a few percents in the worst case (even less in most cases), which, again, is a very small price for not having to die of cancer or even just live with asthma and in constant smog in cities.
Let's not forget about the manufacturing of def and and the waste of plastic containers. So smart!
@@cg5138 For one, DEF (as in Adblue or urea mixed with water) has nothing to do with the DPF, and is used for a completely different purpose. It's not doing something with the DPF, albeit it's there - just like the DPF - to reduce poisonous emission, but a different kind of that: NOx gases, that can cause a wide variety of respiratory diseases. Also, DEF is produced as a byproduct of ammonia production, and its production is actually reducing the environmental impact of that. As for what's smart: smart would be if people would educate themselves about the DPF, DEF and similar stuff, before spitting out stupid statements about it, because for one these are there to save their lives and health, but also because only the really dull ones believe that all this stuff is built into cars not because of very good and valid technical and health reasons, but because of being part of a guvemah conspeerazzy to oppress them.
@@berczigabor yea it's basically identical to the urea that carries all of grain ag today which means it's peanuts in comparison
@@cg5138 I mean how many plastic containers do you buy in a year? So is it really honest for you to complain about that?
You're an Advanced Mechanic - a Scientist Mechanic, really. Thanks for the video
You're most welcome!
😂
Tested and worked perfectly. Bmw 2007 E60 520d dpf removed from car, pre cleaned for about 30 mins. with 1L of mr.muscle drain unblocker (diluted with 1L of water) , this stage will remove grease mainly. After, i used 20L water + 5L brick acid HCL 34%, and let the dpf soak for about 3 hours. I give it a rinse with just a hose garden initially and after a jet wash with 2 bar pressure (no higher than that as you'll destroy your honey comb inside). Also keep your jet wash nozzle/lance at a 200mm distance from dpf honey comb. Water came clean after all this process and had a good flow from both sides. Dried the dpf for few days and reinstalled on the car. Before this diy clean my car was cutting off right after engine start as dpf was fully blocked. Now my dpf readings are: 4mBar at idle, 12mBar at 2000rpm and 42mBar at 4000rpm. Cost for replacing dpf to this 15 years old car is £1400 just the genuine part + labour to install it. Cost for diy this method is under £50 and some diy enthusiasm. My car has the dpf separate from Catalytic converter. Thank you for all your videos Steven. Nowhere on youtube you can't find such detailed explanation.
Awesome result from a job well done! :-)
Many thanks for your research! I did my DPF on 318D F30 using Drain Cleaner and Hydrochloric acid two years ago and since then I have successful 70k km on it. I passed also annual inspection without problems.
Perfect result!
Thank you! Worked like a charm.
My friends Bmw E60 525D had a blocked DPF for 2 years (Warning on display). It was very blocked. I used drain cleaner, mixed it to about 1:10. Then used pure aloy wheel cleaner.
Then i pressure washed the dpf from both sides. (Didnt damage it one bit, even on full blast)
When done i cleared all codes on the engine. (Very important) then used carly dpf request regen to "clear it out" got ash to 1gram.
Now it works like a charm😁
The drain cleaner i used was a Mr muscle type like. With natriumhydroxide
Thanks for sharing your experience!
Really enjoy your channel , love the presenting and the thorough facts and results, brilliant thank you.
Glad you like the vids!
Thanks for this pragmatic approach. The outcome is quite surprising and very interseting.
Glad you liked it! If you are interested in doing a full DPF clean yourself, then my other video is still my favorite method: th-cam.com/video/LE1boZ3fhLg/w-d-xo.html
Most definitely appreciated. I'm and ardent follower of Project Farm.
Hi Steven, Thank you for sharing your knowledge. I First burned the filter off at 650 C for 15 min and then let it soak for a night in dishwasher tablets with water. At last I poured over some cleaning vinegar since it was all I could find easily. And the result is that I can keep on driving the car for another year without having to pay 1000,- for a new filter so thanks a lot. Keep up the good work!
A bit of a hybrid process, but is sounds like it did some good!
I have tried it and it works. The car has been running for almost 3 weeks now with no more issue with DPF. Cheers. The only thing I would emphasize is to make sure that the filter is completely dry, because after installing it there was some water coming from the exhaust pipe, however as recommended by Steve I kept the car on idle for couple of "minutes/hours",.
Great to hear! I have tried all sorts of ways to dry out the filters before refitting, and none of them work all that well, as the ceramic absorbs water like a flowerpot. Overnight in an oven would work, but otherwise a gentle engine warm-up like you have done is probably the best.
@@StevenBTuner What about the differential sensor, will it be damaged with the steam?
@@novak4142 Hi, the differential pressure sensors are at the end of a long thin tube so that nothing actually travels up to them except the pressure.
El mejor video sobre limpieza que he visto👍👍👍👍
Great work, really helpful. Was looking for to these type of tests. Thank you!!!
Hi, thanks for watching, and glad it helps you out!

Sir, your level of detail and work ethic is inspirational! Thank you for such a comprehensive comparison, and I hope you succeed in all your endeavours.
Many thanks for the kind words!
Your Video is worth its weight in gold! Thank you so much!!
You're very welcome!
That acid pool wash seems like the hot ticket.
Hi, it is the best combination of price and availability and consistency that I've found so far.
If you think about most agressive chemicals that can be easyly available to use in the household - there are some cleaners for ovens and fireplaces available in markets and cleaners for water residue buildup - recently they started be really effective . Thanks for your tests
Stove glass cleaner should do best results. And EGR cleaner spray.
Intelligent, precise, calm, methodical, good videographer and editor, doing a good quality work with a touch of humor.
and certainly a nice person in real-life.THANK YOU STEVEN
**bmw 330d e46 facelift 204 hp (M57N), 300000km, and still like new, I don't let any mechanic touch it, I do everything on it on my own**
:-) :-) Always good to hear about folk keeping their cars in great shape!
GREAT video mate and really informative.
Thanks!
Great vid, Steven! After watching, i removed the lambda sensor and poured 4L of Coca Cola through the hole. My engine light has now gone off and my drive smells of ashy Coke. Win!
Haha, that's the wildest method I've heard of yet! Thanks for sharing your great result, and thanks for watching!
Did you let it soak overnight?
And did light came off by itself or by connecting an obd2 diagnostic device? Thanks.
@@pezeshkimh no, i just let it go through the dpf, followed by a kettle of hot water then went for a blast down the motorway. Light went out.
Hi Steven, I tried ALDI all in one dishwasher tablets (not family pack) and Super Alloy concept wheel cleaner (10-25% phosphoric acid, 25-50% hydrochloric acid as per data sheet). Condition of BMW DPF (520 d se2008) -before hand-fuel economy nearly doubled, car sounded juddery sometimes-fuel emission light on frequently-turbo failed a month ago-looks like fuel or something got into engine oil also as oil level increased after turbo replacement. I got the local mechanic to remove the DPF. Crushed 40 Aldi tablets into 15 litres of 40 degree water (15 litres covered my dpf fully) agitated every 15 minutes for two hours . No water flowed through dpf at the beginning - dpf was used for 306,000km. After an hour soot started appearing and breaking down. (Probably could have used 80 tablets as I think this is what you suggested. After two hours soot only was removed (No sign of ash). Washed out with water both directions before next phase of ash removal. Diluted wheel cleaner 1:4 adding acid (12 litres of water and then 3 liters of wheel cleaner ) to water 40 degrees also (kept the hands warm with the rubber kitchen gloves and disposable gloves under these -just in case with safety glasses). Agitated every 15 minutes for 1 hour 30 minutes. Rinsed out with water both directions until no ash seen, then water and washing up liquid, then final rinse with de-ionised water. Dried in oven at 50 degrees for 4 hours . Before the final wash I could see that when using the garden hose that if I placed the hose against a selected few dpf holes the water flowed straight through. I realise this may not be possible for others but this particular dpf allowed me to see both ends. I got the mechanic to re-install and re-set today. After engine warm up fuel economy back to normal. I bought the Altel AP200 unit also so I will check for glow plug issues etc tomorrow. Did test with wheel cleaner on some stainless steel screws beforehand some tarnished and other brands did not . The dpf case did not tarnish. Thanks for the help.
Congrats on a job well done!
If only all you tube video's were as good as this one. Thank you.
Many thanks! :-)
Well produced and much appreciated, at the moment I need information like this. Many thanks.
You are most welcome!
Great video
Love the sarcasm 👍
:-)
Hi Steven, I really liked you`re videos. I found that the best combination to clean a DPF filter is a 2-mol Oxalic acid and Ethylenediaminetetraacetic acid in water. The materials are kinda cheap since you only need a few grams of each per litre and you can do a flush with the engine running. I`ve done this for about 4 times on my own VW Touareg in the last 3 years and the dpf is in best condition.
Hi, that sounds like an excellent solution for in-place cleaning. I'll have to try it out :-)
Hello, sounds good, but how does something like this work with a built-in DPF? Fill in the agent via the lambda sensor opening or temperature sensor opening? What does this do to the differential pressure sensor? Thanks!
Yeah, remove the oxigen sensor and pour about 1-1.5 l solution. Be careful not to pour into turbo. VERY BAD IDEA
@@StevenBTuner please send me you`re thoughts on this after you try it. The original solution is from a german company that does a solution for on-car dpf cleaning
Excellent scientific and unbiased test. Suprising results.
Glad you like it :-)
Love your work Sir - well done!
Many thanks!
Hi Steven,
using acidic solutions only might be a bit of a gamble since acids promote the formation of emulsions and a permanent sludge if too much oil and soot present.
I would suggest adding cationic surfactant to prevent sludge, promote active binding and removal of soot and the acid to remove ash. Go with something like Bezalkonium Chloride in the 1-5% range addition.
(Anionic surfactant and alkaline chemicals are usually in dishwasher powder/tablets)
You might be on to something here.
Great experiment, no sane person would flush part of the exhaust system with coke though :D the added sugar will do more harm than good!
Hi, all good points! In my other vid I do a full DPF clean as a 2 stage process - the first stage is to clean away the oily soot so that the 2nd stage acid wash can do its work.
@@StevenBTuner Yeah I thought of that too, using either hydrocarbons or something like HEATED! sodium hydroxide solution or commercial/restaurant grade glass detergent to take off the soot before attacking the ash.
The surfactant idea is more about creating something like Steven's even more effective mystery wonder solution or concentrate (would buy!!). Why do two soak and rinse cycles if you can make the acid work reliably for both with surfactants keeping the sludge/emulsion particle size controlled and small while the acid is happily eating away at the ash :)
Commercial grade dishwashers are doing basically the same but with an alkaline solution. For plates, the wash cycle detergent is basically potassium hydroxide with added surfactants in the ~5% range to deal with fat/emulsion, glassware only detergents are just potassium hydroxide solution (this is why coffee cups with milk remains, very greasy lipstick prints and plates don't properly clean up in glass washers).
I work for a global manufacturer of commercial dish- and ware washing solutions and content like this really intrigues me acidic route if adjusted right can result in a bucket of pH ~7 neutral watery suspension of ash, salts and soot particles. Mildly acidic one-cycle solutions with surfactants shouldn't be a problem either. Time to check environmental legislation I guess :D
I'd definitely take that route considering the nasty fumes and environmentally unfriendly nature of hydrocarbon based solvents ending up being toxic waste when contaminated.
Having the HCL and NaOH react together at the end to form water and salt is definitely a plus. You can then filter out the remaining particles with a coffee filter :-)
would be interesting if you could try using these as an "on car" application Steven, done similarly to the way DPF cleaning companies do it, soloution fed in via the pressure sensing pipes while car is running, and maybe have a before and after pressure reading, would be the soloution everyone would be interested to see.
HI, thanks for watching! I know exactly what you mean, and it could work for most cars, but I feel that it is way too risky to suggest to folk as a home DIY. I can imagine what could happen, for example, if the cleaning solution went back through the turbo and ended up in the exhaust manifold, and then flowed in through an open exhaust valve and filled up a cylinder.
@@StevenBTuner I would imagine if you limit the fluid volume to say a litre or 2 of each stage or whatever volume the DPF itself would roughly take up then you wouldn't have any issue's on most cars as the amount of pipe from turbo to DPF would comfortably take up way more than a litre on most cars, not to mention the turbo's are always higher than the sump/tailpipe height to allow proper turbo oil drainage so the fluid would 99.999% probably drain out of the tailpipe first, sure, i get that you can't account for the human stupidity factor like someone on a steep hill with front facing down but there's always the "disclaimer" option at the start of the video as well, explain possibly risks, video for info purposes only, do not try if you have an IQ lower than room temperature inside a freezer combined with a lack of common sense to match etc lol
I'm hearing you! :-) A reasonably strong phosphoric acid sprayed in using fairly fine droplets could work like that. If it could be made to foam up somehow that might be even better. The process might be something like: spray in 200ml, wait 30 minutes, then spray in another 200ml, wait another 30 minutes, spray in a liter of distilled water then blow in some low pressure air (14psi / 1 bar) for 5 minutes to dry things out. Such a method could work really well as something done every 2 years or so to keep the filter in top condition.
@@StevenBTuner The pressure differential from the turbo exhaust port into the DPF (let alone from the turbo into the exhaust manifold) would prevent that, the turbo exhaust is always at positive pressure compare to the DPF or the exhaust which is at atmosphere. Otherwise, any exhaust gases would back-flow into the turbo or exhaust manifold as well, which would choke the engine.
Exactely what I was looking for - great video! Thank you 🙂
You are most welcome!
You use an awesome English in my favourite topic of car servicing. Thanks. Look forward for new technic videos
Thanks! :-)
Spray a can of $2 oven cleaner into DPF then flush with Gerni! Couple of days beautiful 👍🤗
Hi, thanks for watching! Oven cleaner is similar to caustic soda so makes a great pre-cleaner to remove oil and oily soot, but unfortunately won't remove any of the 'end-of-life' ash deposits. High pressure washing with a Gerni or a similar unit can cause cracking of the DPF modules as seen in my other video: th-cam.com/video/-0mtz3Icg5o/w-d-xo.html
I wrapped my dpf in titanium wrap and it gets alot hotter during the regen. My regen times have cut by half now. Maybe 12 minutes instead of the usual 19
What a great experiment!
Great videos very informative
Great job on making this video very helpful
Glad you like it!
Caustic soda worked for mine on a 2014 ford ranger.
It is great for getting rid of oily soot.
For jet turbo engines we use a brand called ZOK, pls try that. God to remove sot and aches
Sounds like it would work well.
Really interesting and well put together, very informative, cheers
Thanks!
this is the best video ever I have ever seen... useful and pratique

I hope no one in the family got sick drinking from the glasses. By the way, I drink Coca Cola when I'm a bit under the weather

Brilliant, thank you for your efforts. Dishwasher Tabs. Who’d have thought it?
Hi, thanks for watching! It was a viewer suggestion on one of my other DPF videos, and it turned out to be a good one!
Thanks for this video. Ive just cleaned my 2012 Vivaro's DPF / DOC using dishwasher tablets first followed by oxalic acid alloy wheel cleaner. I had error codes on my dash 'Check Injection' and 'Check Emissions' which means DPF is blocked. The van failed last year's MOT with these warnings so the garage did a clean using aerosols with the DPF still on the van. This turned the warning codes off and got the van through MOT but warnings were back 1 month later. Watching your video gave me confidence to tackle it myself this year ahead of the MOT. I was really nervous about loosening the two manifold nuts to remove the DPF/DOC exhaust section as it's 11 years old, and manifold nuts of that age tend to like staying put. But a good quality socket and a bit of GT85 got things moving.
I used an old dustbin to soak the exhaust in overnight with dishwasher tablets, and some frequent flushing through / agitation soon released a lot of soot. I would say this preliminary cleaning was most affective. Next I drained and rinsed then soaked overnight in oxalic acid alloy wheel cleaner. I'm not convinced this had a huge benefit considering the dishwasher tablets worked so well. Maybe if I'd skipped the dishwasher tablets and gone straight to alloy wheel cleaner then I'd be saying how wonderful it was. Thinking optimistically though, maybe the alloy wheel cleaner removed the important last 5% of soot from deep down in the DPF.
Rinsing the DFP with freshwater took forever to remove the frothing. The flushing water would not run out without some frothing, even after about a million gallons! Not sure what's causing that, either the dishwasher tablet or the alloy wheel cleaner residue in the insulation. I had to call it eventually and run with it. I don't think the frothing would have ever stopped.
I left the exhaust out in the sunshine for about a week to dry out (cant believe we got a week of sun in UK!). Then refitted.
I didn't use the OBD to cancel the warning codes, instead I took the van for a good drive. Pulled over once after 15mins, turned off and on. 'Check Injection' warning had gone. Drove again for another 15 mins, off and on. 'Check Emissions' warning also gone. Alleluia, the dashboard no longer lights up like a Christmas tree.
A week on, and all is good. runs great, no warning lights and the van could be a keeper for another ten years. The only thing I'm concerned about is the Emissions Test at next MOT in few weeks time. Has the dishwasher tablets or alloy wheel cleaner affected the metals on the DOC and that no longer processes CO correctly? I hope its OK or else expensive replacement.
(By the way, despite 1 week in the sunshine to dry out the exhaust, there was still quite a lot of moisture vapor coming from the exhaust on its first run. Only visible when stationary on tickover. It must have been lingering in the insulation. If doing it again, I'd be tempted to leave a hair dryer running through the DPF / DOC exhaust for a few hours also before refitting.)
Thanks for sharing your method and results so far! That ceramic material is like a flowerpot - it just soaks up heaps of water and only an oven or an hour of driving is going to get it to evaporate out again...
I was wondering if blowing compressed air into the DPF would have helped with eliminating some of the water.
That possibly may have some positive effect depending on volume flow rate for a sustained period, but I think a lower pressure/higher volume air flow source would be better over a long period. A dry heated air source would be best. Borrowing the wife's hair dryer and letting that blow through for a few hours would work good.
An update on my van and MOT test........ All good during the emissions test and passed. I hadn't ruined the DOC Cat and all my dashboard warning lights still off. Very happy!
Thanks for the update - awesome result!
I took my dpf out for cleaning but forgot to put it back in, whoops!
Haha, lots of folk make that mistake...
The best way🤣
The red residue is probably the cerine used by Peugeot as catalyst added to the fuel, to bring down the combustion temperature from 550 to around 450 C
My Peugeot 508 - 2012 had the DPF completely plugged, so we cut it open to clean it as it came entirely welded, contrary to other DPF models which can be opened.
When we inspected the filter, it had very low amount of black ash residue, compared to the red ash which was all over the DPF walls, so it was basically plugged with cerine.
We ended up removing the DPF all together and reprogramming the car to work without EGR and DPF.
The red residue is probably Nitrogen Dioxide and ash mixture. The catalyst would have taken care of this gas.
Awesome / helpful 🤝🏼
Another great video, cheers for the information

You're diluting your 32% HCl 1:4 here
In the other video (the brick acid), you were diluting 9.5% HCl 1:4
Aim for 6.5 - 7%
Thanks I cleaned my DPF using your suggestions. Caustic Soda, dishwasher tablets the pool acid at 1/4 dilution and got a stack of black sh!t out, not much orange ash though. Now I get no error codes and runs great. Cheers for that.
Awesome result!
Subbed Brv from here in the UK - Keep the videos coming
Will do!
On both of my cars I cleaned them with hammer and drill. They mapped out along with EGR crap and no problem since😂🖕🏻
You mean apart from the problem that your car now puts out over 50 times more pollution?
You forgot to have water as a negative control in a scientific experiment you must also wash your tweezer when going from one glass to the next
Very true!
I've had the best results from removing it and welding the empty can back together. Works like a charm, still has the catalytic converter intact, passes MOT with soot levels under max permitted value for my car.
Great video, lots of good information
Hi, thanks for watching and glad you like it!
Only clean i know is ... remove and remap ..... pointless thing is a dpf!

We have a fleet of machinery (cat, komatsu, kubota, ect.) We've had great luck simply pressure washing out the dpf filters. Once any of the machines start frequent regens, or will no longer clean them selves effectively through a normal or forced regen, we will pull the dpf off and disassemble them. Then use a low pressure pressure washer (maybe 1500psi) and wash them out from both directions with just water. This seems to clean 90%+ of the soot. The machines always run better and generally take way way longer to even do the next regen because they're so cleaned out it takes a long time to build enough soot back up to need to regen. The first couple times we tried it we were pretty scared to mess something up. But now its become a regular thing and have yet to have an issue. Once the filter is washed out we will blow out with air, place in front of a fan to dry, then reassemble. Codes may or may not need to be cleared. We've done this process probably 40-50 times over the past several years. Its quick and free.
Hi, that works great on older cars too, as long as they don't have an integrated DOC - the catalyst material is easily damaged by the high pressure.
merci pour ce comparatif intélligemment réalisé , ça va m'aider a déboucher mon FAP. merci l'ami
Salut, merci d'avoir regardé ! Ma méthode préférée vient de cette vidéo : th-cam.com/video/LE1boZ3fhLg/w-d-xo.html
Great job! Thanks!
Welcome!
Thank you very much for all your efforts. I'll clean my DPF next week.
Hi, thanks for watching! What cleaning method do you think you'll go for?
@@StevenBTuner Dishwasher tablet for pre-wash, and hydrochloric acid for the ash. Glad I found your videos when I was planning this job. Michael from Melbourne.
:-) That is my new favorite method - so I'd love to hear how it goes! Hope everything is improving in Melbourne with all of the Covid lockdowns.
@@StevenBTuner Thanks Steven, I hope the Covid thing will go away soon, also in the UK. I'll report back.
@@ccfabs8932 yes we hope the lockdowns and restrictions go away soon but considering the numbers of asymptomatic cases its likely that twice as many infected would be untested and contagious ....so it seems the best way to fight it now is herd immunity or this will drag on for a long long time?
Thanks for that...thats what i was thinking too especially as same thing occured last time i cleaned it.
No problem 👍
ASMR for mechanics!! Great video
:-)
Thank you Steven I appreciate your work my Bma will b for keeping
Wooww.. awesome Mann...u r the best .. congrats from India..
Thanks!
I've just spent 20 quid on a bottle of off car dpf cleaner and I've got about 50 dishwasher tablets under the sink. Gutted.
Great video Steven. I'll Try the dishwasher tablet as a pre wash and then use the dpi cleaner fluid. Subscribed and Liked. Thanks Pal..
Give it a go - I'd love to hear about your experience! Some folk have reported that it can work well, but you may have to soak overnight and do some extra shaking.
@@StevenBTuner i used an old baby bath and soaked the dpf in dishwasher tab overnight. the liquid was black don't know if any ash was removed tho i put the dpi cleaner in next. overnight again. and spent 2 hours rinsing it. i put it on the radiator in the hall to dry and fitted it. i had some black liquid coming out the tailpipe but it went after the car was warmed up DPF is fine so far. thanks pal
nice test !
I hope it helps you out!
PRO test. Thanks
You are welcome!
Finished the cleaning process on BMW N47D20A 177 hp.
I used 10 liters of 10% NaOH and 7 liters of 10% HCl. Afterwards I did a lot of vigorous flushing with water and shaking like crazy. Overall about 200 liters of water. DPF backpressure before cleaning was 90-96 hPa and after it is 10-14 hPa at 2700 rpm, and 123-126 hPa -> 24-28 hPa at 3700 rpm. DPF pressure sensor was calibrated at engine off so the results are very accurate! As far is I compared these pressures on BMW forums the DPF after your cleaning method has backpressure as good as a brand new filter! Therefore I applaud you Steven and highly recommend this method. PS after first startup of the engine I was afraid it didnt clean well because the backpressure was as high as before of higher! But this was due to soke water being absorbed in the porous ceramic. After 15 minutes it dried nicely and the pressures are super low!
Well done on doing this job yourself, and many thanks for posting those detailed results! By the sound of those numbers, your filter was very badly clogged, and definitely needed a good clean.
@@StevenBTuner i was hoping to decrease the turbo lag (gas pedal pressed to full torque time) but this didnt really change much in the 1700-2500 rpm range. However above 3000 the engine revs much cleaner and with more ease :) makes sense I guess.
Hi, the most likely reason for a lack of throttle response in that mid-range is a MAF sensor that needs to be replaced. As they get older, they get very slow to respond, and the only way to properly test this is with an oscilloscope.
@@StevenBTuner I have an oscilloscope. What is the parameter to be tested?
@LazicStefan i changed my whole timing chain assembly 70k ago and it runs like new.
Thank you. It's useful
Glad it helps you out!
Great vid! Thanks
Glad you liked it!
Excellent, thankyou.
Hi, thanks for watching!
Very nice video and I like your presentation style
Thanks!
It was so interesting mate all the best for your future projects am not a mechanic but always trying to learn something new thankyou for your effort ☺️☺️👏👏👏👏👏👏👏
Hi, glad you like it!
Brilliant vid you cant beat real world testing you were diplomatic with the WYNN product though lol
Hi, thanks for watching! The Wynn's product did a fair bit over 24 hours, so if you combined it with some vigorous shaking and a good bit of back-flushing then you would probably end up with a filter that was pretty clean. I have noticed that there is a new 'professional' version out now, which maybe is a bit stronger.
Bravo Steven 👍
Thanks!
Very good!
Hi, I hope it helps you out!
Love ya dude!
:-)
good video! thank you
Glad it helped!
You got a like from me when you threw the regular grinder out and brought out the big kahuna grinder
:-) :-)
Another great video Stephen
Thanks 👍
Thanks.
Hi Steve , before to see this video already I've cleaned an DPF with Doctor DPF cleaner and then with caustic soda , I got good result ! DPF it was cleaned more than 90% , anyway Thanks for your video !
Hi, thanks for watching, and glad to hear that you had good results with the method you used! It is much better get these filters cleaned and back into operation, than it is to throw them away, and buy a new one.
@@StevenBTuner Thank you too, your video it was relevant for me , like confirmation !
Hi great video thanks. I had problems with my dpf so put some dishwasher tabs in the fuel tank..its finished
All of the cleaning methods tested are for cleaning a DPF that has been removed from the car.
Quality video, ordered some brick cleaning acid ready to do both my cars :) Not blocked but better to get in there early!
Hi, all the best with a messy job! You are right about getting in early, as there is no good reason to wait until everything is completely jammed, as you will be putting up with years of reduced power and increased fuel consumption. You can see the full process in my other video: th-cam.com/video/LE1boZ3fhLg/w-d-xo.html
Brilliant set of DPF Videos
I checked my Mercedes Sprinter 2013 130 ( 651 Engine) last week before watching your videos and I can concur I had a 90% full DPF and High Nox P2BAC EGR Deactivated
Cleaned DPF with Brick Acid and Petrol
The Petrol /Gasoline cleaned out all of the soot
The Brick Acid dissolved all the ash
The DPF now shows 0% in Diagnostics
The fault code is still there which leads me now to the EGR to being blocked which also supports your explanation in one of your videos of this potentially being the initial fault of the DPF problem
Keep up the great work and stop stealing glasses....
:-) Well done in getting that DPF fully clean, and all the best in getting your van back to full health!
Great idea and very informative. Also great if you are on a budget, most people can afford a dish washer tablet 🙂
Hi, you would probably need quite a few tabs to do the first stage wash, so the sodium hydroxide drain cleaner granules may end up cheaper - but either should work well.
grand job
Thanks!
Thank you for your knowledge and videos USA 🇺🇸 USA 🇺🇸
I hope they help you out!
