We clean DPF's - we weld & repair them too. The DPF on my own vehicle is the original & has 374,000 miles service done. Still works perfectly. Get yours cleaned when it needs it, follow the advice of this video & it will be all G. If it ain't... well there's people like us who can help.
if there is a problem with the car even a brand new dpf will be full in a few days so cleaning it is not always the answer.if something is wrong elsewhere it will not regen , and even a brand new dpf will be ruined in a few days
The whole video idea, concept and conclusions about DPF are right and can be called as a BASE for long lasting DPF. I've been working with DPF's alot and in advance of this video i want to point out some things: 1. Don't listen to those who say that DPF cleaning or 'washing' (call it whatever you want) is pointless, because it is not! If you're doing it in, as i say, basement workshops, they will surely ruin it with agressive chemicals and other stuff. Find a nice, approved workshops who specialize in DPF cleaning procedures, and do it, i would say, every 150k on clock. 2. Don't use any of DPF cleaning chemicals which is supposed to be added to the engine fuel, because it will ruin your DPF's ceramic and you will be in a big PAIN as the ash will stick pretty hard on it. 3. Keep in mind to once in a while check your sensors and keep an eye on active regen cycles, if they are getting often or not. 4. Never, never tune your car with history of bad DPF. 5. Use quality fuel. Besides that thumbs up, information is great. Suggestion for the next video is EGR valve, as it can be a culprit for a DPF related issues.
The info that you have highlighted is "Golden" ... in doing the research for this video I have seen how the DPF system is cleaned for heavy vehicles and same concepts can be used for the our small vehicle DPFs ...
@KD-kf4zm I'm not convinced that's true regards the additives. Some additives simply reduce the temperature at which the Ash burns away. Therefore they can help with shorter journeys
What do you think about the DPF additive that needs to be poured into the fuel tank? I read on many forums that some people use it. Do you think this could help with a longer life DPF?
There are loads of reasons a DPF won't regen: faulty thermostat, broken sensors, fuel tank below 25%, faulty differential pressure sensor, bloked sensor pipework, faulty glowplugs (they are used for more than just cold starts), broken or missing outside ambient temp sensor (the one usually found in a wing mirror). The list goes on.... But the main points are to keep your engine well serviced: at least every 10,000 miles. Correct oil spec for your diesel, usually C3 or C4 low SAPS. And use premium diesel.
@@LesleyStoddard I thought so too as all this means is the more likely you going to have condensation build up in the tank in cold/wet conditions so it's entirely a fuel filter issue not a ptf issue, just means you have to drain/replace the fuel filter more often nothing to do with ptf.
In 4 years my DPF light has only come on once. The rest of the time I'm on the open road running a diesel like it's supposed to be run. What damages these diesel systems is driving them around town at slow speeds and low RPM's. If you're an urban dweller, trade into an EV or gasser.
I bought diesel because i needed the torque for towing,DPF has been major flaw in the system as there is no light or anything to inform that a regen is in operation,so you can pull into the garage for the night and regen is still active,next morning,without actually knowing it.
@@tednoone3414 any tips on the best way to delete it? Looking at buying a 2.0 150bhp diesel as I need it for towing but I do a lot of short journeys too, always drove diesels, love the torque.
@@roadwarrior8560it depends on where you live. However I think you’re also looking at a 2015 or newer version if it’s the 150hp. That brings along challenges with the DEF system. You need to find a tuner that removes those. Do your research for Malone or MR Tuning for the US - they will work well. Then look at the down pipes available for your vehicle along with dpf, EGR, and the requisite block plates/. Some people keep their EGRs. I’ve been told the pcv is an underlying cause of soot buildup and the EGR isn’t an issue but removing the pcv is not an option. Anyways watch delete videos - it will save you some time with some of the kits that are out there.
Some Regens are only triggered by distance they don't all kick in when you go on a drive if dpf is not clogged or over accumulated. If the soot accumulation is bad 30 minutes drive with Regen activated won't be enough. If soot accumulation is high you will find the set distance the Regen should kick in (600km ) is ignored and will Regen more frequently even after completing a full Regen. This means more diesel fuel is being sprayed into the dpf over a longer period of time. Not only is diesel used to move your car but at the same time it's pupmping diesel into the dpf to clean it meaning fuel is being used at a higher rate making you fill up more frequently. Then there is the difference between soot and ash. When soots burned off it leaves ash when this builds up it's worse than soot.

Hello! I have a brand new 6 months old Toyota Innova Kijang/Crysta 2400cc diesel manual, which has done only 4000 kms. It developed reduced engine power and performance,sluggish and choked feeling at 700 kms. Since then the dealership has not been able to solve the problem. They have manually conducted manual/forced dpf regeneration multiple times but the malfunctions have not been rectified. Once after forced dpf regeneration the car improved a little but worsened again.

I would get a diagnostic scanner and check it ... something like th-cam.com/video/mXaAMZUEsMY/w-d-xo.html or the D7 line of scanners. I might make a video showing how to do that ...
@@BestCarMods I know Mercs and Vauxhalls turn on rear heated screen and heated door mirrors (if fitted) when doing regens other manufactures probably do as well, Connect an LED light to one of those circuits and if it comes on when the rear screen is not manually turned on you know its doing a regen, there are youtube videos showing some ways of rigging up the LED, I have one fitted to my Merc C220d and its works really well
Good info, but one of the most important things to check is how much engine oil is being used, if a lot of oil is being used >1 liter per 1000km, then the cause needs to be investigated, wear, bad oil trap for the crankcase ventilation, leaking turbo lubrication etc. This quickly leads to increased amount of soot and ash amount in the particle filter. So be sure to fix this first before cleaning or regenerating the particulate filter regularly.
The manufactuars should put lights on. So you know when its regenerating. so the driver can finish the regen instead of turning it off. I am sure my short drives kils my dpfs. I have had 3 vans of wich one was new who had the check airinlet system and engine light on 95% of ownership.
I've driven a few trucks that tell you when they are doing a regen and one that can do a regen while parked, because it's work involves very little of the type of driving needed for an automatic regen.
I have a Fiat Ducato motorhome 2.2 140bhp 2023 model year completed 11,000 miles. After getting a cheaper scan tool I’ve noticed the regen takes place roughly every 150 miles. The soot level increases to about 85% then not long after does a regen. The pressure looks good at idle around 5mbar and rises to around 45mbar at higher rpm. Is this normal or am I worrying for no cause? I’ve started to use Shell Vmax fuel in hoping it improves the soot level.

I change oil & filter twice a year and any other maintenance as required eg fuel filter (a bitch), glow plugs, coolant, brakes. 177000Km no problems.

Thank you! Your insight will be of great help. I will follow-up with a email and we can sort-out the details. Is this email "ash________es@h____ail.com" good to get in touch ?
theoretically yes for passive regen ... it would also help with the time needed to get the DPF up to temp, however you don't want to be always at that rpm. the temp in the dpf needs to be over 500 deg for the regen to happen but at the same time there is a limit to the max temp ... and the temp for active regen is not achieved by air flow, but by injection in the exhaust faze ... that is used in the DPF to increase temp. .... so to conclude yes and no :)
Hello. I’ve bought an used car, and now, at over 280k km, the dpf needs to be cleaned. What solution do you recommend ? Burning (extreme heat) or wet cleaning (water with a bunch of chemicals). Thank you
the companies that recondition DPFs do both methods ... they heat up the dpf first in an oven (they burn the soot)... and after that use the chemicals to remove ash. It depends on many factors.
I am looking at a car with a known issue right now, lifters have failed in the engine after 100000 miles and expected timing chain failure shortly after... The cause, numerous failed DPF regenerations as a result of driving a diesel car short distances, as diesel ends up in the oil diluting it and causing crank bearing wear, lifter bearing wear, timing chain wear and oil pump/chain wear, and probably anything else lubricated by the oil... The fix is £2500-£5000 depending on damage caused, and will occur again in another 100000 miles or so... All because of DPF technology in some newer cars being flawed.
well said. for this type of situation I am looking at affordable ways of monitoring the DPF condition/regen cycles not completed and load to avoid this ... also would be interesting to evaluate the service intervals and how these could have been improved. how many oil changes has that car had in the 100.k miles?
@@BestCarMods well one way i am aware of it to find something that goes live in Regen mode, apparently on some Mercedes reason unknown the rear window heater comes on during Regen so you can just connect an LED into this and stick it in your dash somewhere, or as one person did inside and existing light that you will see.

@@Robs.channel the GM equivalent to my SUV did have a light and it drove people crazy,imagine driving home for the night and light comes on,and you have no real chance of getting out and doing a regen.People are being stretched just to survive and don't have time to divert to a highway just anytime.
yes correct,and if my latest effort fails i will be forced to do a removal,I don't necessarily want to but will do as my vehicle is still near showroom cond at 12 years,I'm not going to allow it to go to the wreckers to be scrapped just because of a failed flawed system.
I think you need to make sure your glow plugs are in good condition so the vehicle can cold start ok without running on 2 or 3 cylinders as that can cause issues, interesting point about oil consumption so I'd definitely check the inlet to make sure no oil is getting dumped into it, if it is get it checked out & fixed if it's a breather issue. Check engine temp as if it doesn't get hot enough it won't regen so may need a new thermostat, also make sure the exterior temperature sensor is working as if its blank you will get DPF issues.
Also, glow plugs take part in a Regen. As I understand it, diesel is injected on the exhaust stroke and the glowplugs are energised. This is what heats up the DPF to approx 600degrees.
I have drille i whole in the dpf, close off the egr and deleted dpf/egr from computer - still i get errorlight from the dpf sensor..?!! Pls bassist if Anyone can 🙂🇳🇴
Let’s develop an emission system to save the planet, but the only way it’ll work right is if you drive more for longer and burn more diesel? Let’s not mention the millions and millions of cardboard and plastic packaging for the DEF
there are too many vehicles out there in good cond otherwise,seems it's not so easy to develop an aftermarket kit,you would think after 20 years someone would have solved this dilemma us diesel owners are going through,especially as EV's need years and years of further development before they become a viable alternative.
Driving for 20 minutes to an hour at constant speed is nearly impossible when you’re going to work and back the motorways are horrendous lucky if you’re doing 20 mile an hour on there
never thought about it this way. in theory for that you have the active regen, where the ecu injects fuel on the exhaust stroke and increases temps artificially. not to be confused with the forced regen that you see done in the garages. but overall low speed driving might not be the best for the dpf.
Why not just clean the DPF from ash? It seems quite easy using dilute hydrochloric acid. The only problem if you don't have a garage with a lift is to get the darn thing off of the car.
the problem is as you have highlighted that the part is not designed to be cleaned. 1. it is hard to reach 2. it is welded 3. it is close to the catalytic converter. however the DPF is not failing ... something else fails and the dpf is just a byproduct
@@BestCarMods But (at least in Europe) the increased monthly taxes and other costs are not compensated by the improved fuel economy if you drive such short distances.
@@cbats1888 it is not effective ,n the long term, to use a diesel for short trips. maybe the first owner that has a vehicle up to 5 years does not have to see the serious damage, but after 5year the bills will start to show up.
@@BestCarMods I do not know what is a new car, can't say what this feeling is. It's just a car. You go in and you go out after some time.

@@BestCarMods That's my next goal, which will be almost impossible to buy such car with less than 100k. I will be happy to find such person that want's to sell me :)
Any device that demands you drive differently and further to work properly means more emissions overall! In time engines wear so that they’ve less chance of passing relevant tests and temporary fixes include a new DPF and all the sensors that are seized in cost a bloody fortune…..so the answer is to scrap it and start again with a new one? How big will the carbon footprint be for that operation? Built in obsolescence and a lifespan of three parts of FA seems to be the way we’re heading right now.
sadly that is how the economy works :) ... also don't forget that cars get scrapped even faster due to high labour cost in some countries. EVs are even worst because off all the EV precautions and specialised tools and training required...
@@cliffordkirk4825it has nothing to do with CO2. The emissions are bad for the lungs and cause a lot of health problems, and smog. If nobody cared about CO2 these things would still be installed.

@@BestCarMods yeh, that’s fine. Think I’ll be having a discussion with my boss this week about doing something with you.
Would driving at 2-3k rpm help with having a stronger exhaust flow?
theoretically yes for passive regen ... it would also help with the time needed to get the DPF up to temp, however you don't want to be always at that rpm. the temp in the dpf needs to be over 500 deg for the regen to happen but at the same time there is a limit to the max temp ... and the temp for active regen is not achieved by air flow, but by injection in the exhaust faze ... that is used in the DPF to increase temp. .... so to conclude yes and no :)
DPF regen happens above 200c with an oxidation catalist
Higer egt temps can be reached between 1500 - 1800rpm, therefore this is better for regen, both passive and active.
Hello. I’ve bought an used car, and now, at over 280k km, the dpf needs to be cleaned. What solution do you recommend ? Burning (extreme heat) or wet cleaning (water with a bunch of chemicals). Thank you
the companies that recondition DPFs do both methods ... they heat up the dpf first in an oven (they burn the soot)... and after that use the chemicals to remove ash. It depends on many factors.

I am looking at a car with a known issue right now, lifters have failed in the engine after 100000 miles and expected timing chain failure shortly after... The cause, numerous failed DPF regenerations as a result of driving a diesel car short distances, as diesel ends up in the oil diluting it and causing crank bearing wear, lifter bearing wear, timing chain wear and oil pump/chain wear, and probably anything else lubricated by the oil... The fix is £2500-£5000 depending on damage caused, and will occur again in another 100000 miles or so... All because of DPF technology in some newer cars being flawed.
well said. for this type of situation I am looking at affordable ways of monitoring the DPF condition/regen cycles not completed and load to avoid this ... also would be interesting to evaluate the service intervals and how these could have been improved. how many oil changes has that car had in the 100.k miles?
@@BestCarMods well one way i am aware of it to find something that goes live in Regen mode, apparently on some Mercedes reason unknown the rear window heater comes on during Regen so you can just connect an LED into this and stick it in your dash somewhere, or as one person did inside and existing light that you will see.
@@BestCarMods Hello!
I have a brand new 6 months old Toyota Innova Kijang/Crysta 2400cc diesel manual, which has done only 4000 kms. It developed reduced engine power and performance,sluggish and choked feeling at 700 kms. Since then the dealership has not been able to solve the problem. They have manually conducted manual/forced dpf regeneration multiple times but the malfunctions have not been rectified. Once after forced dpf regeneration the car improved a little but worsened again. My questions are:-
1) Is it possible for the DPF to get clogged at just 700 kms?
2) Is it possible to get the DPF removed and get my car remapped without any side effects?
I am from India.
@@HYukti-k8w 1) yes the DPF can get clogged up in 700km
2) yes, however in many countries it is ILEGAL to drive on the road cars without the emission control systems fitted from the factory.
More details about your local rules should be known by the companies that do ENGINE REMAP in your local area.
Got rid of my diesel, DPF is the devil, cars regen and you don't know about it, so switching the car of mid regen is really bad
Ye, why is there no dash light on when it's on regen. This always puzzels me
@@Robs.channel the GM equivalent to my SUV did have a light and it drove people crazy,imagine driving home for the night and light comes on,and you have no real chance of getting out and doing a regen.People are being stretched just to survive and don't have time to divert to a highway just anytime.
better getting rid of the dpf than the diesel car imo. Diesels worked fine without this stupid shit.
excellent information thankyou
I am glad to see it was useful.
Good presentation; I worry that my Range Rover 4.4D doesn't get a good blast because even at motorway speeds the engine is barely doing 1500 rpm.
Drop it down a gear or two then. 20 mins @2500 - 3000rpm should get things moving, so long as all other Regen parameters are met.
@@AdamDitheridge Thanks.
too many things can cause this to not regen ,,even an outside temep senor fail will stop the dpf from regen .its a constant battle.
yes correct,and if my latest effort fails i will be forced to do a removal,I don't necessarily want to but will do as my vehicle is still near showroom cond at 12 years,I'm not going to allow it to go to the wreckers to be scrapped just because of a failed flawed system.
@MrLeslloyd remove it and get it remapped pal. Will be OK.
@@connectlogic thanks m8!
I think you need to make sure your glow plugs are in good condition so the vehicle can cold start ok without running on 2 or 3 cylinders as that can cause issues, interesting point about oil consumption so I'd definitely check the inlet to make sure no oil is getting dumped into it, if it is get it checked out & fixed if it's a breather issue. Check engine temp as if it doesn't get hot enough it won't regen so may need a new thermostat, also make sure the exterior temperature sensor is working as if its blank you will get DPF issues.
Also, glow plugs take part in a Regen. As I understand it, diesel is injected on the exhaust stroke and the glowplugs are energised. This is what heats up the DPF to approx 600degrees.
If you have an auto with a dpf run it in sports mode, it raises the revs and runs hotter.
that is a option that you can do from time to time ... i would not keep it in sport mode all the time.
I have drille i whole in the dpf, close off the egr and deleted dpf/egr from computer - still i get errorlight from the dpf sensor..?!!
Pls bassist if Anyone can 🙂🇳🇴
.. And car is grunning, but with very little power..
@@solskivenrt7516 send me a email @ 8hello@bestcarmods.com
Let’s develop an emission system to save the planet, but the only way it’ll work right is if you drive more for longer and burn more diesel? Let’s not mention the millions and millions of cardboard and plastic packaging for the DEF
interesting perspective
there are too many vehicles out there in good cond otherwise,seems it's not so easy to develop an aftermarket kit,you would think after 20 years someone would have solved this dilemma us diesel owners are going through,especially as EV's need years and years of further development before they become a viable alternative.
The dpf looks surprised 😮
use premium diesel, drive your diesel on motorways once or twice a week for 40 minutes, should be fine.
Gut it and map it out, simple.
I avoid it not once have i had a problem. My solution i drive a petrol.
🤣🤣🤣
Driving for 20 minutes to an hour at constant speed is nearly impossible when you’re going to work and back the motorways are horrendous lucky if you’re doing 20 mile an hour on there
never thought about it this way. in theory for that you have the active regen, where the ecu injects fuel on the exhaust stroke and increases temps artificially. not to be confused with the forced regen that you see done in the garages. but overall low speed driving might not be the best for the dpf.
Why not just clean the DPF from ash? It seems quite easy using dilute hydrochloric acid. The only problem if you don't have a garage with a lift is to get the darn thing off of the car.
the problem is as you have highlighted that the part is not designed to be cleaned. 1. it is hard to reach 2. it is welded 3. it is close to the catalytic converter. however the DPF is not failing ... something else fails and the dpf is just a byproduct
If you only do short trips you should be driving a petrol.
:) true, but some people like their diesels
How to complicate engineering should be simple . Simple means less time in workshops
Don't get the Adobe version.
?
Driving in London traffic will clog your DPF.
😂
with that 20 mph limit :) yes yes definitely yes
Best way to avoid DPF problems is to not have a DPF
@@BestCarMods Hi, how does the egr valve or blanking it effect the dpf , please BCM ?
@@nigelmitchell351 theoretically it will cause a DTC and the engine ECU will not allow active DPF regen.
Fully agree with u .buy a petrol car if u have anykind of brain.
HOW TO Avoid DPF Problems? Simply remove it.....
Best way to avoid DPF is not to buy a diesel car
😏
The best tips to avoid a miserable life, is to NEVER, EVER under any circumstance buy a vehicle with dpf
I will use this expression in a video :) .... NEVER, EVER under any circumstance ...
If around 70% of your single trips are not longer dan 40-50 km's, why buy a diesel car anyway?
because at a first glance the diesel is more economical, better on theoretical fuel economy.
@@BestCarMods But (at least in Europe) the increased monthly taxes and other costs are not compensated by the improved fuel economy if you drive such short distances.
@@cbats1888 it is not effective ,n the long term, to use a diesel for short trips. maybe the first owner that has a vehicle up to 5 years does not have to see the serious damage, but after 5year the bills will start to show up.
I fully agree with that, that's why I don't think anyone should buy a diesel for trips shorter than at least 50km's single trip :D
I buy my cars when they are over 400 000 km. For me 300 000 km are not much.
Finally someone that is crazier than me! Tell me this, when you get in someone's car and see 100.k don't you feel that is a new car ?
@@BestCarMods I do not know what is a new car, can't say what this feeling is. It's just a car. You go in and you go out after some time. Most of the time you talk to someone or drive and watch trough the window. The only difference is how soft it rides and is there something rattling, is there any smell.
@@MrDelgrigorov I see people that tell me they need to change their car, an when I see they have less than 100.k , for me that is a new car :)
@@BestCarMods That's my next goal, which will be almost impossible to buy such car with less than 100k. I will be happy to find such person that want's to sell me :)
Any device that demands you drive differently and further to work properly means more emissions overall! In time engines wear so that they’ve less chance of passing relevant tests and temporary fixes include a new DPF and all the sensors that are seized in cost a bloody fortune…..so the answer is to scrap it and start again with a new one? How big will the carbon footprint be for that operation? Built in obsolescence and a lifespan of three parts of FA seems to be the way we’re heading right now.
sadly that is how the economy works :) ... also don't forget that cars get scrapped even faster due to high labour cost in some countries. EVs are even worst because off all the EV precautions and specialised tools and training required...
just delete it lol
It's a scam this co2 crap 😂
@@cliffordkirk4825idiot. DPF has nothing to do with co2…
@@cliffordkirk4825it has nothing to do with CO2. The emissions are bad for the lungs and cause a lot of health problems, and smog. If nobody cared about CO2 these things would still be installed.
If mine needs replacing that’s what the dealer said as it’s 200,000k plus atm .. shouod I delete it ? And wouldn’t this harm the engine as the computer tells the car to be in the dieeel at a certain point ?
That’s why when I change oils and filter they reset computer to let it know it’s been changed ?
@@Semaj.18272 no if u delete it it will not harm the engine , it will make the engine run easier with more fuel economy & power
buy a petrol
yes, now just for fun, do you know that there is a GPF that does the same thing as the dpf for petrol cars ?
No good for towing,and if you do fuel consumption skyrockets.So not for everyone.
avoid diesels
😁
One more reason to hate government
I would not go that far 🥳
Buy a petrol, that’ll teach them
Just get rid of Diesel,Simple.😎
It is hard to let go ... I had only diesel cars :)
