I’m SO GLAD I’ve kept good care of my rust-free 2003 Dodge Ram 3500 Cummins! None of this crap to deal with. For over 22 years this thing has run reliably, and other than rebuilding the manual transmission 5 years ago, and the lift pump and the water pump- oil changes and fuel filter changes have been all that Ive ever done.
It’s an older proven technology. I have rebuilt a 2008 Mercedes CDI last year. Been using it as my touring vehicle. It’s much better than the new electronic circuses they are selling now . But U am curious. Why would you need to rebuild the tranny ? Don’t manuals last as long as the vehicle?
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.
@@johnpatterson5744 No more than 10mbar on idle, ideally half that and 50mbar at 3krevs is very good AFAIK. The DPF will normally get blocked for a reason.... Built in fault code with some vehicles (around 120k miles), sensors not working, nozzles blocked, etc.
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.
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!
I wonder if you could get a ultrasonic actuator from one of those ultrasonic cleaners, attach it to the dpf and see if you could get the cleaner to cavitate and therefore super activate the cleaner.
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 🙏
a thought Mel, as I wish to remove my DPF ...my idea is to remove the exhaust like yours, then cut a hole through the ceramic to put a straight pipe through, welded to each end. This way it looks like the dpf is there, but the gases are going straight through, and have the dpf shut down on the ecu. :)
Lots of people do that. Your car runs far more economically and smoother and it’s very difficult to tell that it’s been done. People also remove the DPF and replace it with a straight pipe and if your car has to be inspected. Put the DPF back on.
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 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.
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...
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.
@@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.
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..
@@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 ...
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.
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.
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)
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.
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.
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, 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.
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.
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 Your reasoning for taking off the dpf to be cleaned is flawed. The dpf captures the bigger particles created at lower temperatures when the engine is cold. Then burns them off during the regen allowing them to passthrough the filter. Blowing a cleaning solution into the dpf dissolves the soot into small enough particles allowing it to passthrough the filter.
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.
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,
More 'forever chemicals' finding their way into our drinking water. These are not totally cleared out by current water treatment practices with 18 out of 20 plants tested having well over limits deemed safe (although even that is a daft idea, they are not safe at all). We all (literally) pay the price for laziness like this.
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.
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
In theory your right, in actual fact you are incorrect. Wet cleaning is just as effective from the 'inlet' end of the DPF especially if the DPF is near vertical such as a Mercedes S class. One other point, is the heat sensor going to be at the right depth into the gas flow...
@@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.
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.
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.
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 👍
@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 ?
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
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.
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 !
The fluid they put in the DPF dissolves the soot and the engine pressure pushes it out ,and launch fluid works better mate ,but I could see the method in your madness, any how not every body has the time to do this method they need the car for work
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 😳
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 😀👍
Im not a fan off DPF how ever they there for a reason and work reasonable well untill the mileage get to around 100.000 mile then we all have problems However in my experience the dpf is blocked by oil coming from the crankcase breather filter which is blocked As the soot and ash build up then you add engine oil fumes you have a real stick mess inside your dpf Check inside intercooler pipe make sure it bone dry if not you will soon block the DPF
@ 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?
There are several reasons why there are companies that clean filters. 1. they use hot liquid for washing. 2 they recycle the liquid. 3 their cleaning liquid is filtered and the waste is disposed of correctly. 4 there is a guarantee on their work. Not like your solution, where chemical liquid and particles run directly onto the ground and contribute to contaminating the groundwater. It doesn't matter now, it's your grandchildren who can't drink water, unless it's cleaned WITH chemistry to remove solutions that you and others use now. think about it
Like talking about exhaust gases in Glasgow, pointless with the winds we get,same with rain,the environment with filter it...worry more about volcanic activity!
@@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
If you were just going to use water to rinse it, i wouldn't have bothered with the treatment solution. Best way to clean these is heat and airflow, just like it would get on the vehicle.

@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.
@@johnpatterson5744 No more than 10mbar on idle, ideally half that and 50mbar at 3krevs is very good AFAIK. The DPF will normally get blocked for a reason.... Built in fault code with some vehicles (around 120k miles), sensors not working, nozzles blocked, etc.
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.
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!
great vid ,i did mine with 2 cans of oven cleaner.
Nice 👍
I wonder if you could get a ultrasonic actuator from one of those ultrasonic cleaners, attach it to the dpf and see if you could get the cleaner to cavitate and therefore super activate the cleaner.
I have absolutely no idea 🤷♂️
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!
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 👍
a thought Mel, as I wish to remove my DPF ...my idea is to remove the exhaust like yours, then cut a hole through the ceramic to put a straight pipe through, welded to each end. This way it looks like the dpf is there, but the gases are going straight through, and have the dpf shut down on the ecu. :)
That would be an mot fall and it’s against the law to remove the DPF from the vehicle
Lots of people do that. Your car runs far more economically and smoother and it’s very difficult to tell that it’s been done. People also remove the DPF and replace it with a straight pipe and if your car has to be inspected. Put the DPF back on.
So what about the downstream located particulate censor, that’s going to throw a code isn’t it ?
@@georgerenton965not if the dpf has been mapped out properly. I do this as a side hustle 😁
Thanks for the get back Art. 👍
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
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 👌👍👍
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 👍
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 way to clear dpf how needs to go to garage looking forward for further video thanks
change the wing mirror for the DPF problem, the outside temp sensor may be missing or damaged.
It’s all fixed now thanks though 👍
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...
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
The Soot that comes out of a diesel is actually 99% carbon. It is only temporarily airborne. Plantes love it.
You are very original meister. Respect👍
Thank you kindly
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 ...
Hola. Te faltó eliminar el material incinerado en el DPF ( de color rojizo).... solo eliminaste el hollín.....
Correct 👍
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.
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.
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)
Thank you!
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 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 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.
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 ..
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
Interesting video. Plenty of clever tips. Best wishes from CarSpyTV.
Thanks for watching!
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 👍🤓👍
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.
How many liters of the Wynn’s DPF Cleaner was needed to fill your DPF?
What year is your Sprinter?
All of 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. 👍
Thanks for the advice 👍
Hello, I want to clean my Prius 3 catalytic converter. Do you know can I use this product for my car? Thanks
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.
@BigVansmallWorld
Your reasoning for taking off the dpf to be cleaned is flawed. The dpf captures the bigger particles created at lower temperatures when the engine is cold. Then burns them off during the regen allowing them to passthrough the filter. Blowing a cleaning solution into the dpf dissolves the soot into small enough particles allowing it to passthrough the filter.
Very nice coverage of the cleaning methodology.
Thank you.
My pleasure
Did you have to plug the holes mate to let it soak overnight?
Yeah I did that 👍
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
If the DPF is blocked will it stop the engine from starting??
No I don’t think so but it definitely affects the performance
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
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 .
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,
Сделал из болта штуцер для сенсора ... Из оцинкованного болта . 🤦🏻♂️ А надо из ... А вот из какого в следующий раз 😂
DISCLAIMER: No plants where killed in the making of this video from DPF Residue over spill :)
that rite
I thought that was a bit naughty
More 'forever chemicals' finding their way into our drinking water. These are not totally cleared out by current water treatment practices with 18 out of 20 plants tested having well over limits deemed safe (although even that is a daft idea, they are not safe at all). We all (literally) pay the price for laziness like this.
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
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
In theory your right, in actual fact you are incorrect. Wet cleaning is just as effective from the 'inlet' end of the DPF especially if the DPF is near vertical such as a Mercedes S class. One other point, is the heat sensor going to be at the right depth into the gas flow...
Thank you 🙏
Good knowledge sir! thxs for sharing
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.
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
How would you unblock a sink?
by getting a plumber az its totally differnt ,obviously
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.
Thank you Mell..... great as usual.......😊
You are so welcome
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.
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.
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.
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 👍
Mel you should of put Evapo Rust on the hole thing £16 from Tool station Now on sale was £22
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 ?
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
😂😂😂
Just wondering does anyone know oven cleaner or WD-40 work?also how long will that cleaning out filter last for cheers
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
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.
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 👍😂👍
The fluid they put in the DPF dissolves the soot and the engine pressure pushes it out ,and launch fluid works better mate ,but I could see the method in your madness, any how not every body has the time to do this method they need the car for work
Dpf aren't so expensive if you replace your self and maybe 1hour of your time.
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 .
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 😀👍
Hot soap an water probably do the same thing
Im not a fan off DPF how ever they there for a reason and work reasonable well untill the mileage get to around 100.000 mile then we all have problems However in my experience the dpf is blocked by oil coming from the crankcase breather filter which is blocked As the soot and ash build up then you add engine oil fumes you have a real stick mess inside your dpf Check inside intercooler pipe make sure it bone dry if not you will soon block the DPF
That is probably the most helpful comment I’ve had on here thank you 🙏
Why not cut the broken bit off completely and the manufacture a new bit then weld it on?
I did something like that
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
There are several reasons why there are companies that clean filters. 1. they use hot liquid for washing. 2 they recycle the liquid. 3 their cleaning liquid is filtered and the waste is disposed of correctly. 4 there is a guarantee on their work.
Not like your solution, where chemical liquid and particles run directly onto the ground and contribute to contaminating the groundwater. It doesn't matter now, it's your grandchildren who can't drink water, unless it's cleaned WITH chemistry to remove solutions that you and others use now. think about it
Like talking about exhaust gases in Glasgow, pointless with the winds we get,same with rain,the environment with filter it...worry more about volcanic activity!
Whatever coming out..is it environmental friendly??
Its only Ash
You'll have the environment agency on the blower,about contamination of the ground from washing it outside 😂
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

Nice make sense 👌
Glad you think so!
Hi have you put the end result after refitting on RUclips
Yeah it’s all good 👍
If you were just going to use water to rinse it, i wouldn't have bothered with the treatment solution. Best way to clean these is heat and airflow, just like it would get on the vehicle.
Thank you for the advice
