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.
Great video. Thanks!
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 ...
Do you have an example of the chemicals added to fuel that should be avoided (point #2) ?
@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
@@at0micsheep If you need those chemicals, something else is wrong. If you ONLY have shorter journeys, you should probably not have a diesel.
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.
Delete hardware+software,no smoke,no smell nothing...car runs super good !
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.
thanks for taking the time to share some knowledge
Good explanation
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.
verry good observations
You’ve got some good knowledge on dpf systems. (I’ve spoken to my boss who’s said you’d like to do a video on our cleaning process) but I’d like to help you with some of the technical back ground if your interested?
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 ?
@@BestCarMods yeh, that’s fine. Think I’ll be having a discussion with my boss this week about doing something with you.
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?
Yes increased Cetane reduces soot 50%
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.

Clean your dpf Injector spray nozzle. DPF Crystals build up on the nozzle and disrupts the spray pattern.
Need your help to remap a Nissan Qashqai 2012 model....we removed the DPF and so need to remap it
that is not a service that we offer at the moment
Don’t be a selfish idiot. Put the dpf back on the car.
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
use premium diesel, drive your diesel on motorways once or twice a week for 40 minutes, should be fine.
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
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.
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.
Best way to avoid DPF is not to buy a diesel car
😏
Fully agree with u .buy a petrol car if u have anykind of brain.
