Great video thank you! I always thought it was odd that people say you can't clean a dpf. Odd because we worked for Eminox who make dpf filter systems for heavy goods and PSv etc. every year the Filter is swapped out and the dirty one sent to eminox to get cleaned. It's about time car manufacturers or exhaust companies offered a cleaning service (maybe they do, I've no idea)
Cleaned mine with the same fluid about 2 months ago, back flushed when rinsin aswell maybe 20-30 times also used air pressure which help blow out some of the red ash at the end and alot of the water. Worked for me lowered my dpf pressure from 250mbar at 3k rpm to 50mbar at the same revs. I also used the same chemical as brick acid which really helped with the red ash was a weakened version but did the job.
The pressure in the DPF should be no higher than 10 mbar.and one should never let the diesel fuel in the tank drop below a quarter,preferably a half tank of diesel for the DPF to function properly.👍
@johnpatterson5744 50mbar or kpa can't remember at 3k rpm this was directly after cleaning with water still coming out and before it has done a regen aswell. Havnt checked it since, but will check it this weekend and see what it's at now 4 months later.

Been 6 months now its flushed all the water, lose soot and Ash out that was broken up by the chemicals along with a few natural regens. The pressure is 6mbar on idle and around 50 at 3.5k so it did the job very well and was very easy to do.

did mine an old 520 bmw took it of soaked it in a big bucket with two dishwasher tabs and half a bag of soda crystals for an hour washed it out with a hose and refitted power restored and no lights on cost about a quid 😁😁😁😁😁
Dishwasher tablets will do a good job of removing oil and soot, but you need an acid after that to get rid of the metallic ash as well. ruclips.net/video/Zw-EAc_Lpv8/видео.html tests 9 chemicals on a chopped-up one to see how well they work in practice.
I broke one of the sensors when doing that on my wifes X trail. After i was told "you didnt need to do that" I did have trouble getting it dry, Blew air thro after draining and flushing from a workshop vac outlet connected to the pipe and heated the pipe in front of the core with a blow lamp on and off for about 30 minutes.
I leave the DPF on the vehicle. Just disconnect the exhaust joints and cover the exhaust holes with plastic bags. Then stick the powerwasher lance up its snout. You don't have to disconnect any sensors as they do break unfortunately. I just fitted a new NOX sensor, but all the threads stripped removing the old one. I just drill it out, sit the sensor in place and mig the sensor. Saves a lot of hassle
Top job mell that's exactly how I do mine, keep flushing till there's no foam it can take 45mins with jet wash, the soots not a problem, it's the ash left behind 👍
I’ve got a Toyota Coaster , ever since I first bought it the DPF has been giving me continuous grief and lots $ in professional cleans by diesel mechanics, recently installed is a new DPF filter ($1600 ) after a another scan resulted in the DPF being blocked.DPF is still not performing proficiently despite the new filter as it’s not reaching high enough temperature to complete a thorough burn . The DPF warning light was flashing on the turn of the ignition start up .After each burn the malfunction light comes on.Presently replacing the manifold outlet hose as there was a tear in it . Let’s see how effective the burn is after the hose replacement 🙏
I have a 2010 VW Polo TDI, and almost exclusively do short trips. You can notice when the DFP-filter cleaning cycle starts. The telltale signs are: choppy running at lower rpm, extra smoke, and bad smell coming from the exhaust. Higher idle RPM, goes from 900 to over 1000. Whenever this happens I simply go on a high octane detour from work, instead of going straight home. Had zero problems, since I started doing this. Now the car only goes into cleaning occasionally, instead of all the time, fuel mileage has also improved, except for the times I drive it like i stole it to clean the filter...
It's great to hear that you've found a solution for your Polo TDI! Those DPF cleaning cycles can be a hassle, but it sounds like you've got it figured out. Keep up the good driving!
Cleaning the dpf on the van is also an option , i used manol dpf cleaner injected through the pressure sensor pipe . Works without taking dpf off , which is very tricky on renault trafic as high up behind engine.
This worked perfectly for me on a 2010 Audi TT TDI. Was in limp mode and soot load was so high it was beyond the level for forced regeneration. Mannol DPF cleaner in from the top reduces the load far enough that forced regen was successful and all is good now.
Chemical DPF cleaning agents are designed to break the carbon down into smaller "particles" so they CAN be flushed out of the filter in the direction of flow.
Great video mate, just a quick one would I able to undo that nut on the pipe that connects to the exhaust that holds the thin pipe? Access on mine is very limited, I can only access that nut with that thin long pipe. Was thinking undoing it and spraying cleaner inside it.
@@randoshanks I followed same method as O’Rileys Autos on you tube used wynns dpf cleaner pumped fluid in pressure pipe before dpf lots of videos on you tube also sprayed dpf cleaner in air intakes as per revive product video on RUclips.

@@BigVanSmallWorld had a dpf censor but lights kept coming on was showing injector fault on dash but not when garage plugged into computer... had dpf deap clean over 300 miles ago and no warning lights coming on ...
The way the filters are made it work forwards and backwards. I think a fire hose from the back would be best though. These filters are a total pain and the regens do not work well, my older diesels had no problems with these or the ADBLUE because they were not there.😊
At high enough temps during a regen cycle the black carbon should burn off... its the white ash that comes from the additives and oil burning and such that clogs them up... and by about 100,000 km it's effects get noticeable. Unfortunately the regen cycle won't burn that ash off.. so your method will help hopefully get rid of the ash but not damage the latticework inside... wondering how that high pressure hose affects things inside...
Mel, could you have brazed the drilled out bolt in place, maybe clamping it in position? Though perhaps tack welding in place will be sufficient. Clever plan to use the bolt to seat the sensor, very resourceful.
Did my crv dpf this week. Bit of a bastard to get out as its right down the front of the engine and a heat shield gets in the way. Once out cut the heat shield corner and you will makes life alot easier. The chemicals and additives just dont work. Save your money. Just take it out and clean it. Jetwash, chemical soak, jetwash. Back in , force a regen and its good as new.
You will get better results with your welding if you prepare the area you are going to weld by cleaning it as much as you can. A wire wheel or brush works good.
how does a DPF get blocked on a camper? we use a camper for holidays, weekends or even day trips - usually all long(ish) journies including motorways or dual carriageways. Never had an issue with DPF.
You answered your own question with "long(ish)" journeys . I live in mine , it doesn't go on holiday , it's either sitting or goes 20 mins up the road to do work at my parents house which i try to avoid or i'll do in 5th gear at 2k rpm to run it hotter because model diesels with dpf simply arn't made for short journeys
@mel I have a problem you may have come across mate. I have a 2017 sprinter - pooling water in the footwell by the pedals. Heavy rain is giving me water . The material against the firewall is soaked Checked the roof and around the window seals and can’t find anything untoward Anywhere else I should check ?
@@patkelly9907 Crankcase breather pipe. It's normal to have some oil residue going through the intake. The unfortunate part is the oil vapour mixes with sooty EGR gases in the intake manifold and turns to gunk attaching itself to components and over time clogs everything up.
Do you know if it is necessary to reset the ECU once you change the DPF with the scanner or a regeneration to get the new values from the differential pressure probes?. I have to change it for a new one, it is very saturated.
The DPF is a particle filter. Cleaning it in reverse does make sense but if you are using a chemical to disolve the particles then cleaning it in either direction will work. BTW, cleaning using the vechicle inbuilt system to burn off the carbon is a better method.
It will not burn it off always, and will continue to build up small amount by small amount. The best way is to clean it manually, or put DPF cleaner fluid after some time which will allow soot to be burned on lower temperature, because it is less likely we can achieve required temperature for regeneration. It would need 3000 rpm or more constantly which is almost impossible in the city. Or just sitting in the car with 3000rpm foot on gas pedal but questionably for how long. Older cars do not tell you when they start or finish regeneration.
Dpf are not fit for purpose. To prevent blocking people who don't do a high mileage have to do a hard run for 40 minutes once a week to keep it clear. How can this be good for the environment.
I have had a 2016 sprinter for a few months . Every 500 miles or so the exhaust smoke leaks from the drivers side bonnet and gives off a sulphur kinda smell . This lasts about 10 mins then it's fine Took it too a local diesel garage and they said that's nothing too worry about , just the dpf purging ?? I'm not 100 % convinced' ?
Yeah mine definitely smells odd when it’s doing a regen actually did it today I and as soon as I could smell it I looked at my rear view mirror and sure enough it was smoking does it every time and sometimes it’s embarrassing 😳
The main reason the contaminants dont flow through the filter is because the particle size is too big. by using a solvent the dissolved contaminants can become smaller than the filter can hold and it will exit, so those on-car cleaning methods *can* work, but taking it off and cleaning in both directions is by far the best way.
Cleaning a dpf while in place is often a cheaper and easier option due to the location of the dpf and due to exhaust sections being seized together. But, it does not clean as well as removing the dpf and back flushing to clean it.
Years ago I looked after forklift trucks in chemical plant, they had large honey Combe spark arresters on the exhaust, always used pressure washer, but importantly they were allowed to dry in a heated room, otherwise the soot stuck to them very quickly, like you see on videos in situ loads of steam but builds up too quick if not dried. 👍
@@BigVanSmallWorld unfortunately I don’t have the funds to take to a garage. I’ve used everything including the foam dpf cleaners and it’s still saying dpf on my scanner. Now again goes into limp mode switch off and on the van drives fine again. Getting fed up. Starting to feel my ecu is fucked because ever time I scan it comes up with other sensors then I scan again and there gone :( I sick of these modern vans
Basically yes they are the one I broke was a heat sensor the two pipes are for a pressure sensor that senses the difference in pressure between the inlet and outlet of the DPF if the pressure is high on the inlet side and low on the outlet this tells the ECU that the DPF is blocked 👍
@ it’s been running perfectly fine since but I did have to get the ECU re set to 0 soot so it started from 0 again Sort of resetting the ECU into thinking that the last regeneration worked hope this makes sense! Basically you will still need to get a mechanic to plug it in to do this
Hi Mel have you tried just putting petrol mixed into the diesel makes the engine run bit hotter but clears the DPF my truck fitter gave me the idea and it worked put about one gallon of petrol into a full tank of diesel .worked on my Renault Master van?
I vrone down up scotland blocked DPF so ordered a reconed one from DPF clean team down Lester £750 😱 causw of the blocked DPF was a machanic fitting a cheap sensor and couldnt delete the engine management light which wouldnt allow the DPF to regenerate. Cost me a thousand pound in total and ruined trip.
So,they put these filters on the vehicle so it doesn't polute or contaminate the enviroment but loads of people are flushing them out like yourself (and i'm not pulling you on it as i would do exactly the same) with some kind of detergent/chemical and then rinsing it down the drain or into the nearest grass verge etc which then contaminates the enviroment,what nonsense. I just cannot see any difference between the old steam engines were they had to clean the soot and clinka out of the boilers and this dpf filter,it's ridiculous. Great video glad you got the soot and clnka out 😀👍
great demo.....instead of the soot going to the atmosphere as you drive.....flushing down the drain in one go.......defeats the whole object of reducing emissions......so whats the point of dpf's
i had problems with me last kuga had to remove the dpf to clean it. did clean it before via dpf pressure sensor tube this worked just as well as the removal watching the pressure drop on my forscan system. then doing DPF rest the values. the biggest problem is people don't investigate correctly as to why the DPF regen is not working in the first place to keep it clean. Mel this could be to the fact that your DPF pressure sensor is faulty. also make sure that your sensor when you get fits in place and goes as deep into the exhaust as the original or you could get incorrect readings. that sensor works like a 02 sensor it needs exhaust flow over it hence the holes in it.
1/4 pool acid 37%- will do the job as well :)))) I think you broke not heat sensor, this is particular matter sensor- it reads pressure and sends info to computer. This is how you find out that dpf is blocked.
@danielhines5698 In a normal regeneration cycle the soot is burnt off at high temperature, very different to removing soot by chemical methods. Slightly different to using a chemical flush and then pouring the resultant debris in an open ditch. I'm sure Mel is a lovely chap but he is in this case setting a very poor example. Sorry if that offends you or Mel but sometimes the truth hurts. I
@@Dickie2702it's soot that's basically carbon. Carbon actually absorbs lots of bad stuff - it's used in NBC suits and filters and such, so while looks dirty it's ok. No worse than emptying a BBQ.
If you drive plenty it should never need doing. My work transit has never had an issue and currently on 170000 I do 250/400 miles a day I guess that’s the trick
So let's all drive around for 300 miles a day for no reason at all adding pointless miles , other wear and tear at our own cost not mention the £80 a day in fuel to save fixing or cleaning a dpf filter 😂 Ermm no . We'd all do that if we had the time paid for , company diesel card and the company paid the services / tyres and maintenance .
it doesnt matter which way its flushed, best not to use narrow stream or turbo nozzle pressure washer on ceramics. soot doesn't matter, it can be flushed out after soaking in dishwasher tab or washing liquid, its the red ash that needs dissolving. wynns works to a point and needs 2 days, actually coca-cola works pretty much the same. alloy cleaner or HCL works better and does the job in 2-3hours,
The reason why dpf additives are used inline with the flow is because they make tue ash burnable thus allowing the filter to catalyze it , still a nasty process for the enviroment
A restricted/blocked DPF is the biggest killer of turbo's due to excessive back pressure. If only the DPF's had an access panel for cleaning without having to remove them.
That's probably why a lot of companies clean a dpf on the vehicle? You went from a £60/100 job to £500 or more depending on vehicle ! BUT you have only fixed a symptom of a fault that was causing your dpf to not be doing regens to burn away the soot ! Usually when they block it's because of ASH that needs cleaning but soot is usually a different problem !
I cleaned mine by removing it and fitting a straight piece of pipe. No more DPF issues and very happy with it. Also blocked off the EGR valve. Of course got an engine light so I removed the lamp. All good now.

Feel you on the DPF hate...really curious about your comment about remapping, how involved is this? Like, do I need an engineering degree? Or can it be preformed using a VAG/vcds tool? As someone who's looking to learn more and is comfortable with mechanical work, can you steer me to where/how to get started? i have a 2012 JSW 6M btw, Thnaks
great vid ,i did mine with 2 cans of oven cleaner.
Nice 👍
Excellent way to clear dpf how needs to go to garage looking forward for further video thanks
did mine an old 520 bmw took it of soaked it in a big bucket with two dishwasher tabs and half a bag of soda crystals for an hour washed it out with a hose and refitted power restored and no lights on cost about a quid 😁😁😁😁😁
Oh brilliant 👏👏👏
Dishwasher tablets will do a good job of removing oil and soot, but you need an acid after that to get rid of the metallic ash as well. ruclips.net/video/Zw-EAc_Lpv8/видео.html tests 9 chemicals on a chopped-up one to see how well they work in practice.
I broke one of the sensors when doing that on my wifes X trail. After i was told "you didnt need to do that" I did have trouble getting it dry, Blew air thro after draining and flushing from a workshop vac outlet connected to the pipe and heated the pipe in front of the core with a blow lamp on and off for about 30 minutes.
Well done 👍
I leave the DPF on the vehicle. Just disconnect the exhaust joints and cover the exhaust holes with plastic bags. Then stick the powerwasher lance up its snout. You don't have to disconnect any sensors as they do break unfortunately.
I just fitted a new NOX sensor, but all the threads stripped removing the old one. I just drill it out, sit the sensor in place and mig the sensor. Saves a lot of hassle
Nice 👍 thanks for the tip 👍🤓👍
Could you post a video showing that? it would be helpful to leave the pipe in place.
Top job mell that's exactly how I do mine, keep flushing till there's no foam it can take 45mins with jet wash, the soots not a problem, it's the ash left behind 👍
Good to know thank you 🙏
@@BigVanSmallWorld leave them over nt if you can gives 💯, better results 👌👍👍
Great video. Best thing for the DPF is a long chisel and a hammer 😉
Great tip! Lol 😂
I’ve got a Toyota Coaster , ever since I first bought it the DPF has been giving me continuous grief and lots $ in professional cleans by diesel mechanics, recently installed is a new DPF filter ($1600 ) after a another scan resulted in the DPF being blocked.DPF is still not performing proficiently despite the new filter as it’s not reaching high enough temperature to complete a thorough burn . The DPF warning light was flashing on the turn of the ignition start up .After each burn the malfunction light comes on.Presently replacing the manifold outlet hose as there was a tear in it . Let’s see how effective the burn is after the hose replacement 🙏
I feel your pain and frustration hope you get to the bottom of it 👍
You can backwash it with soapy water then rinse. It always works
change the wing mirror for the DPF problem, the outside temp sensor may be missing or damaged.
It’s all fixed now thanks though 👍
How long does it take to dry after cleaning, before I can refit the DPF?
@@Sirparker I left it over the weekend and it still foamed out the tall pipe
You can connect pressure tank as for the truck tire mounting and fill the dpf with water, open the air tank and it will purge the dpf.
Interesting 🧐
Excellent video. After refitting do you need to tell the ecu it's been cleaned/renewed or can you just clear the dtc code.
Yes I’m told that is exactly what I need to do video coming up soon 👍🤓👍
I have a 2010 VW Polo TDI, and almost exclusively do short trips. You can notice when the DFP-filter cleaning cycle starts. The telltale signs are: choppy running at lower rpm, extra smoke, and bad smell coming from the exhaust. Higher idle RPM, goes from 900 to over 1000. Whenever this happens I simply go on a high octane detour from work, instead of going straight home. Had zero problems, since I started doing this. Now the car only goes into cleaning occasionally, instead of all the time, fuel mileage has also improved, except for the times I drive it like i stole it to clean the filter...
It's great to hear that you've found a solution for your Polo TDI! Those DPF cleaning cycles can be a hassle, but it sounds like you've got it figured out. Keep up the good driving!
Cleaning the dpf on the van is also an option , i used manol dpf cleaner injected through the pressure sensor pipe . Works without taking dpf off , which is very tricky on renault trafic as high up behind engine.
Thank you
This worked perfectly for me on a 2010 Audi TT TDI. Was in limp mode and soot load was so high it was beyond the level for forced regeneration. Mannol DPF cleaner in from the top reduces the load far enough that forced regen was successful and all is good now.
100%correct, sir. Lots of people are doing it in the wrong direction.
Thank you for the positive feedback really appreciated
From the ODBC2 readouts I see, the usual cleaning method is very effective too!
Chemical DPF cleaning agents are designed to break the carbon down into smaller "particles" so they CAN be flushed out of the filter in the direction of flow.
Great video mate, just a quick one would I able to undo that nut on the pipe that connects to the exhaust that holds the thin pipe? Access on mine is very limited, I can only access that nut with that thin long pipe. Was thinking undoing it and spraying cleaner inside it.
Yes, absolutely
what about using white vinegar to flush it out ?
Try it let me know how it goes
I cleaned the dpf on my Range Rover on the car with 100% success and will do at every service with lots less hassle
Care to share how you cleaned your DPF? Did you use the same method or a different method?
@@randoshanks I followed same method as O’Rileys Autos on you tube used wynns dpf cleaner pumped fluid in pressure pipe before dpf lots of videos on you tube also sprayed dpf cleaner in air intakes as per revive product video on RUclips.
How just to help others please 😊
injector warning lights on my renault trafic and had it plugged into computers 5 times had new dpf cencor and some other part but lights kept coming on and after a year of this another gargage checked it over said it needed dpf deap klean so far done 300 miles and been great feels like it has more power as well....for a 2012 van with 181.000 on the clock still good for her age..
As far as I’m aware of you have any warning lights on your van won’t do a re gen and that’s why the DPF clogs up
@@BigVanSmallWorld had a dpf censor but lights kept coming on was showing injector fault on dash but not when garage plugged into computer... had dpf deap clean over 300 miles ago and no warning lights coming on ...
The way the filters are made it work forwards and backwards. I think a fire hose from the back would be best though. These filters are a total pain and the regens do not work well, my older diesels had no problems with these or the ADBLUE because they were not there.😊
Hello... during cleaning should I remove the sensors off the dpf
I’m not sure if you have to I did and I broke my so if ever I need to do it again I wouldn’t remove them good luck with yours
At high enough temps during a regen cycle the black carbon should burn off... its the white ash that comes from the additives and oil burning and such that clogs them up... and by about 100,000 km it's effects get noticeable. Unfortunately the regen cycle won't burn that ash off.. so your method will help hopefully get rid of the ash but not damage the latticework inside... wondering how that high pressure hose affects things inside...
Mel, could you have brazed the drilled out bolt in place, maybe clamping it in position? Though perhaps tack welding in place will be sufficient. Clever plan to use the bolt to seat the sensor, very resourceful.
But it won't be in the correct position
Did my crv dpf this week. Bit of a bastard to get out as its right down the front of the engine and a heat shield gets in the way. Once out cut the heat shield corner and you will makes life alot easier. The chemicals and additives just dont work. Save your money. Just take it out and clean it. Jetwash, chemical soak, jetwash. Back in , force a regen and its good as new.
You will get better results with your welding if you prepare the area you are going to weld by cleaning it as much as you can.
A wire wheel or brush works good.
Thanks for the tips
Hello, I want to clean my Prius 3 catalytic converter. Do you know can I use this product for my car? Thanks
You are very original meister. Respect👍
Thank you kindly
Interesting video. Plenty of clever tips. Best wishes from CarSpyTV.
Thanks for watching!
how does a DPF get blocked on a camper? we use a camper for holidays, weekends or even day trips - usually all long(ish) journies including motorways or dual carriageways. Never had an issue with DPF.
Good question!
You answered your own question with "long(ish)" journeys . I live in mine , it doesn't go on holiday , it's either sitting or goes 20 mins up the road to do work at my parents house which i try to avoid or i'll do in 5th gear at 2k rpm to run it hotter because model diesels with dpf simply arn't made for short journeys
We don't all have the luxury of houses with driveways to sit them on and a choice of 2nd or 3rd vehicles to use instead of the camper ..
Would the high pressure from the washer do damage to the dpf
Not at all it’s been working great ever since
@mel I have a problem you may have come across mate.
I have a 2017 sprinter - pooling water in the footwell by the pedals.
Heavy rain is giving me water .
The material against the firewall is soaked
Checked the roof and around the window seals and can’t find anything untoward
Anywhere else I should check ?
Great video Mel
It’s my next job now I’ve seen how bad my EGR valve and intake manifold was clogged with oil and soot
Good luck 🤞
You need to ask your self were is the oil coming from There should be no oil EGR and DPF we're designed for dry soot and ash only
@@patkelly9907 Crankcase breather pipe. It's normal to have some oil residue going through the intake. The unfortunate part is the oil vapour mixes with sooty EGR gases in the intake manifold and turns to gunk attaching itself to components and over time clogs everything up.
Do you know if it is necessary to reset the ECU once you change the DPF with the scanner or a regeneration to get the new values from the differential pressure probes?. I have to change it for a new one, it is very saturated.
Yes you do 100% i had to have this done on mine but i was sick at the time so didn't film it sorry. good luck with yours
@@BigVanSmallWorld I have not scanner. Ummm. Thanks.
The DPF is a particle filter. Cleaning it in reverse does make sense but if you are using a chemical to disolve the particles then cleaning it in either direction will work. BTW, cleaning using the vechicle inbuilt system to burn off the carbon is a better method.
I completely agree with you except The carbon isn’t the problem it’s the ash that is left behind that blocks them and needs to be removed
When someone leaves comments like that, I know they've never even had a vehicle with a dpf 🙄
It will not burn it off always, and will continue to build up small amount by small amount. The best way is to clean it manually, or put DPF cleaner fluid after some time which will allow soot to be burned on lower temperature, because it is less likely we can achieve required temperature for regeneration. It would need 3000 rpm or more constantly which is almost impossible in the city. Or just sitting in the car with 3000rpm foot on gas pedal but questionably for how long. Older cars do not tell you when they start or finish regeneration.
Very nice coverage of the cleaning methodology.
Thank you.
My pleasure
Just wondering does anyone know oven cleaner or WD-40 work?also how long will that cleaning out filter last for cheers
The Soot that comes out of a diesel is actually 99% carbon. It is only temporarily airborne. Plantes love it.
If the DPF is blocked will it stop the engine from starting??
No I don’t think so but it definitely affects the performance
Dpf are not fit for purpose. To prevent blocking people who don't do a high mileage have to do a hard run for 40 minutes once a week to keep it clear. How can this be good for the environment.
environment is YOU
Can you updates us please? Did your dpf lights came back?
All ok 👍 not had a problem since
How many months have you travelled since last dpf clean up? By the way i think you are an amazing guy thanks for your this video.
How did it turn out? Ive searched a hundred videos but this is the only that does what im looking for but its not complete.
its working great studio.ruclips.net/user/videoftMeUlUL4eg/edit?o=U
Did you have to plug the holes mate to let it soak overnight?
Yeah I did that 👍
Hola. Te faltó eliminar el material incinerado en el DPF ( de color rojizo).... solo eliminaste el hollín.....
Correct 👍
I have had a 2016 sprinter for a few months . Every 500 miles or so the exhaust smoke leaks from the drivers side bonnet and gives off a sulphur kinda smell . This lasts about 10 mins then it's fine
Took it too a local diesel garage and they said that's nothing too worry about , just the dpf purging ??
I'm not 100 % convinced' ?
Yeah mine definitely smells odd when it’s doing a regen actually did it today I and as soon as I could smell it I looked at my rear view mirror and sure enough it was smoking does it every time and sometimes it’s embarrassing 😳
My smoke comes out of the bonnet
Be convinced , that's a regen .
The main reason the contaminants dont flow through the filter is because the particle size is too big. by using a solvent the dissolved contaminants can become smaller than the filter can hold and it will exit, so those on-car cleaning methods *can* work, but taking it off and cleaning in both directions is by far the best way.
Good knowledge sir! thxs for sharing
Cleaning a dpf while in place is often a cheaper and easier option due to the location of the dpf and due to exhaust sections being seized together.
But, it does not clean as well as removing the dpf and back flushing to clean it.
Yeah I know
Years ago I looked after forklift trucks in chemical plant, they had large honey Combe spark arresters on the exhaust, always used pressure washer, but importantly they were allowed to dry in a heated room, otherwise the soot stuck to them very quickly, like you see on videos in situ loads of steam but builds up too quick if not dried. 👍
Thanks for the advice 👍
How many liters of the Wynn’s DPF Cleaner was needed to fill your DPF?
What year is your Sprinter?
All of it
Hi Mel I know it says off car but is it possible to do this on vehicle as I don’t have the means or place to remove it ?
yes you can but to be honest i would take it to a garage and get them to do it for you
@@BigVanSmallWorld unfortunately I don’t have the funds to take to a garage. I’ve used everything including the foam dpf cleaners and it’s still saying dpf on my scanner. Now again goes into limp mode switch off and on the van drives fine again. Getting fed up. Starting to feel my ecu is fucked because ever time I scan it comes up with other sensors then I scan again and there gone :( I sick of these modern vans
You should go downtown and blow air backwards through the DPF, wafting all the soot into the air, so that the circle of irony is complete.
Amen brother
😂😂😂
Can you name all the tubes and wires going on to the dpf? it's not all sensors are they?
Basically yes they are the one I broke was a heat sensor the two pipes are for a pressure sensor that senses the difference in pressure between the inlet and outlet of the DPF if the pressure is high on the inlet side and low on the outlet this tells the ECU that the DPF is blocked 👍
good video what did you use to clean it🤔
Wayne’s Dpf cleaner
@BigVanSmallWorld thanks did your van rum well after it🤔
@ it’s been running perfectly fine since but I did have to get the ECU re set to 0 soot so it started from 0 again Sort of resetting the ECU into thinking that the last regeneration worked hope this makes sense! Basically you will still need to get a mechanic to plug it in to do this
@BigVanSmallWorld ok fella thanks for that 👍
another question fella. was it difficult to take off🤔and what was your vans symptoms 🤔
Hi Mel have you tried just putting petrol mixed into the diesel makes the engine run bit hotter but clears the DPF my truck fitter gave me the idea and it worked put about one gallon of petrol into a full tank of diesel .worked on my Renault Master van?
This could seriously damage your fuel pump I wouldn’t recommend doing that
Thank you Mell..... great as usual.......😊
You are so welcome
Mel you should of put Evapo Rust on the hole thing £16 from Tool station Now on sale was £22
My Karcher make the same noise as yours when trigger not squeezed.
Interesting 🤔
It’s not normal, I’ve had mine about 20yrs and it started doing it last yr, it pulsates like yours, no idea why.
Possibly one or more broken springs on plungers . If so can be replaced as I did for a clone. Fiddly but extends useable life aka eco friendly
@@jondor654 Thanks.
I vrone down up scotland blocked DPF so ordered a reconed one from DPF clean team down Lester £750 😱 causw of the blocked DPF was a machanic fitting a cheap sensor and couldnt delete the engine management light which wouldnt allow the DPF to regenerate. Cost me a thousand pound in total and ruined trip.
Hi Mel were you getting any driving or performance issues prior to doing this clean out.
Yes was going into limp mode 👍
@@BigVanSmallWorld Thanks. Did you get any dash warning lights showing up when it was going into limp mode.
So,they put these filters on the vehicle so it doesn't polute or contaminate the enviroment but loads of people are flushing them out like yourself (and i'm not pulling you on it as i would do exactly the same) with some kind of detergent/chemical and then rinsing it down the drain or into the nearest grass verge etc which then contaminates the enviroment,what nonsense.
I just cannot see any difference between the old steam engines were they had to clean the soot and clinka out of the boilers and this dpf filter,it's ridiculous.
Great video glad you got the soot and clnka out 😀👍
Nice video Mel.
Thank you that’s very kind of you to say 👍🤓👍
That filter should be oven dried after wet cleaning before it is reinstalled.
Why, it is no different than condensation flowing through when a cold engine starts.
Hi have you put the end result after refitting on RUclips
Yeah it’s all good 👍
Are you going to tell us the dpf is still showing a problem and actually it was the exhaust back pressure sensor (£45)?
No not at all it’s actually working fantastic now I have cleaned it and reset the ECU
great demo.....instead of the soot going to the atmosphere as you drive.....flushing down the drain in one go.......defeats the whole object of reducing emissions......so whats the point of dpf's
I have absolutely no idea 🤷♂️ they are just a pain in ass and a waste of time as most people are just cutting them out and re mapping there ecu
You'll have the environment agency on the blower,about contamination of the ground from washing it outside 😂
i had problems with me last kuga had to remove the dpf to clean it.
did clean it before via dpf pressure sensor tube this worked just as well as the removal watching the pressure drop on my forscan system. then doing DPF rest the values.
the biggest problem is people don't investigate correctly as to why the DPF regen is not working in the first place to keep it clean.
Mel this could be to the fact that your DPF pressure sensor is faulty.
also make sure that your sensor when you get fits in place and goes as deep into the exhaust as the original or you could get incorrect readings.
that sensor works like a 02 sensor it needs exhaust flow over it hence the holes in it.
That’s so true
How would you unblock a sink?
by getting a plumber az its totally differnt ,obviously
1/4 pool acid 37%- will do the job as well :))))
I think you broke not heat sensor, this is particular matter sensor- it reads pressure and sends info to computer. This is how you find out that dpf is blocked.
Hey Mel handy having that drainage ditch to wash all the Crap into .
Yeah just like all them people that wash their cars every weekend 👍
Congratulations for creating your own environmental disaster! I'm no eco warrior but I really can't approve of your disposal method.
That's what happens on a regeneration....drive up the motorway and all the crap flies out the back ..... leave Mel alone
@danielhines5698 In a normal regeneration cycle the soot is burnt off at high temperature, very different to removing soot by chemical methods. Slightly different to using a chemical flush and then pouring the resultant debris in an open ditch. I'm sure Mel is a lovely chap but he is in this case setting a very poor example. Sorry if that offends you or Mel but sometimes the truth hurts. I
@@Dickie2702it's soot that's basically carbon. Carbon actually absorbs lots of bad stuff - it's used in NBC suits and filters and such, so while looks dirty it's ok. No worse than emptying a BBQ.
Whatever coming out..is it environmental friendly??
Its only Ash
If you drive plenty it should never need doing. My work transit has never had an issue and currently on 170000 I do 250/400 miles a day I guess that’s the trick
I think you could be right 👍🍻
So let's all drive around for 300 miles a day for no reason at all adding pointless miles , other wear and tear at our own cost not mention the £80 a day in fuel to save fixing or cleaning a dpf filter 😂 Ermm no . We'd all do that if we had the time paid for , company diesel card and the company paid the services / tyres and maintenance .
Never mind the dpf how did you manage to sharpen the drill bit on that wheel.never works for me. 😂
Years of practice 😊👍🍻
it doesnt matter which way its flushed, best not to use narrow stream or turbo nozzle pressure washer on ceramics. soot doesn't matter, it can be flushed out after soaking in dishwasher tab or washing liquid, its the red ash that needs dissolving. wynns works to a point and needs 2 days, actually coca-cola works pretty much the same. alloy cleaner or HCL works better and does the job in 2-3hours,
The reason why dpf additives are used inline with the flow is because they make tue ash burnable thus allowing the filter to catalyze it , still a nasty process for the enviroment
Gut DPF. Have a remap deleting adblue ( if used).
That’s e legal
@@BigVanSmallWorld And.......
You do not have a DPF &🎉 ADD BLUE in same vehicle, it is one or the other !
wow Great job yang man well done 😀👌
Thanks 😁
A restricted/blocked DPF is the biggest killer of turbo's due to excessive back pressure. If only the DPF's had an access panel for cleaning without having to remove them.
Is it acceptable to allow this substance to enter the drainage system?
No it’s not that’s why I re bottled it
...... "I'll be right back" *talks back to phone screen: you're not going anywhere boy!! 🤣🤣🤣🤣
I’m really sick right now sorry i didn’t end the video like I usually do 🙏
Nice make sense 👌
Glad you think so!
That's probably why a lot of companies clean a dpf on the vehicle? You went from a £60/100 job to £500 or more depending on vehicle ! BUT you have only fixed a symptom of a fault that was causing your dpf to not be doing regens to burn away the soot !
Usually when they block it's because of ASH that needs cleaning but soot is usually a different problem !
You’re right there thanks for that 👍😂👍
Great work Mel 👍
Thank you 😁
