Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%. Some filters are single-use, intended for disposal and replacement once full of accumulated ash. Others are designed to burn off the accumulated particulate either passively through the use of a catalyst or by active means such as a fuel burner which heats the filter to soot combustion temperatures. This is accomplished by engine programming to run (when the filter is full) in a manner that elevates exhaust temperature, in conjunction with an extra fuel injector in the exhaust stream that injects fuel to react with a catalyst element to burn off accumulated soot in the DPF filter,[3] or through other methods. This is known as filter regeneration. Cleaning is also required as part of periodic maintenance, and it must be done carefully to avoid damaging the filter. Failure of fuel injectors or turbochargers resulting in contamination of the filter with raw diesel or engine oil can also necessitate cleaning.[4] The regeneration process occurs at road speeds higher than can generally be attained on city streets; vehicles driven exclusively at low speeds in urban traffic can require periodic trips at higher speeds to clean out the DPF.[5] If the driver ignores the warning light and waits too long to operate the vehicle above 60 km/h (40 mph), the DPF may not regenerate properly, and continued operation past that point may spoil the DPF completely so it must be replaced.[6] Some newer diesel engines, namely those installed in combination vehicles, can also perform what is called a Parked Regeneration, where the engine increases RPM to around 1400 while parked, to increase the temperature of the exhaust.
Diesel engines produce a variety of particles during combustion of the fuel/air mix due to incomplete combustion. The composition of the particles varies widely dependent upon engine type, age, and the emissions specification that the engine was designed to meet. Two-stroke diesel engines produce more particulate per unit of power than do four-strokediesel engines, as they burn the fuel-air mix less completely.[7]
Diesel particulate matter resulting from the incomplete combustion of diesel fuel produces soot(black carbon) particles. These particles include tiny nanoparticles-smaller than a one micrometre (one micron). Soot and other particles from diesel engines worsen the particulate matter pollution in the air and are harmful to health.[8]
New particulate filters can capture from 30% to greater than 95% of the harmful soot.[9] With an optimal diesel particulate filter (DPF), soot emissions may be decreased to 0.001 g/km or less.[10]
The quality of the fuel also influences the formation of these particles. For example, a high sulfur content diesel produces more particles. Lower sulfur fuel produces fewer particles, and allows use of particulate filters. The injection pressure of diesel also influences the formation of fine particles

#dpf #fix #save
Fantastic advice from a real mechanic. Most would say its all sorts of things and charge you a small fortune. This video needs to be shared far and wide to help prevent people from being ripped off !!!
I’ve worked in the industry longer than you and I’ve never met anyone who WANTS to rip anyone off. I’ve seen misdiagnosis before, yes, that is called human error, but all you can do is try to do better next time. We can only hope to be as perfect as you.
@@Fullsendfilosophy I've had many garages', that have tried, to rip me off!!
Most garages are rip off merchants
You do know they don't actually give you a new DPF! They take the old one out clean it spray it with a rattle can if your the kind of customer to check if it was actually changed and then charge you thousands for a new one! A new dpf is no better than a cleaned one. Bloody gangsters!!!
Wish I knew these things prior to having a car with a DPF. Could have saved a lot of money and many headaches.
I'm well impressed......how the hell did you figure that out?! ......I have a leaky crack - you wouldn't want to put your lips near it though :-)
Lol
Just use a lighter near the 'crack'...quick regen! Butt be careful!!!!!!!!!!!!!!!!!!!!!!!!!!
Moving the hose a little bit, watch the pressure different value change.
Proper mechanic, the plug in “technicians” today would state new DPF every time!
Exactly. Most shitty "mechanics" nowadays only know hot to replace parts which any monkey with proper tools and a lift can do. Proper troubleshooting and understanding how stuff works doesn't happen anymore
Damn straight.
They're doing that to me right now. Telling me I need a new one
JEEZ an honest mechanic THE WORLD IS CHANGING FOR THE BETTER, JUST WISH I KNEW WHERE YOU ARE AS I HAVE AN VW POLO 1.6TDI WITH THE DREADED DPF. I;M Ex mechanic,Ex class 1 lorry driver and Ex mobile Crane operator but got very sick 2010 so find it hard to work on my own car. LOVE THE TIP THOUGH MATE THANK YOU SCOOBS UK.
Thanks, but you're not actually showing how to fix the problem.You're showing how to ensure that you know you have a problem.Then the troubleshooting starts. But anyway thanks valuable information
Another great video Leon, and something that every diesel owner should watch! Thanks mate, and hope you are staying safe and well.
Thanks mate you too
I'm looking at a Vauxhall insignia,dpf fault in limp mode ,that's all the info I have on vehicle
Really Genius, a piece of advice that is hard to imagine... BIG THANK YOU!
That really was an excellent tip. So bloody common DPF and EGR problems these days. Thanks fellas.
Thanks mate
Stop gap repair, cut pipe at split and insert short length of suitable sized thin wall stainless pipe from your "never throw away treasure chest" !
Trying to convince myself not to delete the dpf , and every video I watch in TH-cam about DPF and EGR drives me to delete it immediately and live in the era of Euro 3 . By the way , I live in country have no environmental enforcement yet!
Thanks for your help with this! Dealing with a sprinter in limp mode as well as a hissing noise that i just picked up. Hoping its something as simple as the hose
done loads of these on mondeos also injector blocks up and can be cleaned with welding wire. A real PIA to get out tho very very tight. The pipe is very expensive as well
You can get good aftermarket pipes now
Yes mate it's a nightmare when they get blocked
Yes mate you just need to make sure you get the exact right pipes otherwise they would just melt on u
Great video my VW Transporter 5cyl was plagued by DPF blocking and sensor problems and a simple pipe could have been the key to solving that. The garage repeatedly replaced the sensor as faulty then after 2 years on limp mode said the only option was to remove the DPF and remap.
Thanks mate glad you enjoyed the video may be best off not thinking about that he could have just been a split pips
I'm going thru it some mechanics are clueless but know what they charge
Thanks mate, I've got one tomorrow, on a A3 Audi, and I'd never have thought of this first .
IOU. 1Pint, Guinness.
Awesome tip mate, the pipe looked perfect before removing the sleeve 👍👍👍👍 cheers
Thanks mate boom sorted lol
Very common on the focus 1.6tdci 👍 and the vapourisor on the 2.0 and transits , the new shape quasqui pressure sensor pipe blocks up and a pita to get to 🤦♂️
👍💪
I didn’t think the PDF’s are so expensive any more. I challenged a Peugeot main dealer about this. £1200 fitted for a Partner HDI. I said nope, I’ll go elsewhere, get one and fit myself. Dealer then say they can supply me a ‘spurious’ one. Ahh you mean a pattern part that’s half the price and comes out the same factory. Yes please! £220 later, four bolts and a play on the laptop later, it’s fixed. £1200 my ar@e!
Great video this one. I’m sure at a main dealer that would have been a DPF and a pipe mind.
👍
My Renault Kangoo 2 (2019 1,5 L diesel K9K) had the same issue. One day the engine went into full error - I guess the soot had reached a high level and on a hot day, the temp reached 700 C in the DPF as I was stupid enough to let the car drive at 900 RPM (took the gear out to cruise 200m) coming into a crossroad - that probably caused lack of gas movement in the DPF (keep the gear in so you have at least 1500 RPM pushing the gases - so that the DPF won`t overheat while you drive the car) that was already too full of soot and the temperature sensor maxed out - gave an error - also an error with the DPF dif. pressure sensor (which may have been there for awhile - me unaware of it - the engine light was on - but it is so general that it can be an ABS fault also - if you don`t have a Fault Code scanner - you have no clue). I changed one of the two pipes and the sensor (DPF differential pressure) was fine (I had bought a new sensor also but did not install it in hopes that it was not necessary - I used contact cleaner on the sensor opening after removing the tube). I used the opening of the pipe (while installing a new) to put in DPF cleaning liquid from a bottle of aerosol - went driving it for 20 min at 3000 RPM - it cleaned the pipes - the exhaust gasses from behind the car came out like 4x more powerfully after the drive (it is like soap - gets the accumulated carbon out - which normally cannot be burnt, only soot turns to CO2 and gets out of the DPF). Then a mechanic with a diagnostic computer cleared the error - and it started to regen itself as in order while normal driving. Then I got a diagnostic computer myself and saw clearly how it starts the Combustion mode and how the level of soot in the DFP goes down as does the differential pressure while I drove 90 kph on a highway. No eco mode button on, and it was visible that while normally the car takes 4,5 L/100km, then during regen or i.e. combustion mode - it took 7 L/100 km about 8 minutes (start looking at your fuel consumption - it is the only indicator that the Regeneration is happening). I kept driving on the highway till the fuel consumption dropped to 4,5 L/100kgm again, as I did not want to ruin the regen. It took me 13 hours to change the tube, with 2 flashlights with magnets, tools secured with lanyard, so they do not drop behind the engine, a mirror on a stick, and only one hand barely reaching down there (no freaking room for even pliers !!, used my fingers to get the metal squeeze rings open and self-made hook around a finger - made from a wire), before that I had taken open the window wiper cover metal, it sucked - the worst and hardest job I have done in my life, but it worked. So 1. Get your own fault scanner - so you can see what the fault code it is. 2. Use the scanner to clear the fault code after the fix. So it will start to regen again by itself. (If you don`t clear the sensor fault code, the regen does not work - official Renault manual tells so also. The ECU keeps on thinking that the sensor is not fixed even if you have fixed it physically or its tube.) 3. Use the scanner to confirm that the regen is happening (and the car is not a ticking time bomb - accumulating soot until 100% and goes into error). I use Delphi 2021 (10b) program (and a physical scanner piece - the Delphi program`s drivers manage it) on a laptop - works excellent from Aliexpress and shows live data and with a push of a button records the parameters you choose during a car drive - displays them later in a graph. A freaking miracle. Stop being a victim of mechanics who are not transparent about their business. Get yourself a scanner.
Happened to my 2009 Mondeo a few years back also. The entire hose at the back connection was burnt completely off. I just replaced both hoses with transparent silicone hoses. Still works perfect.
boom sorted
What is max temperature those pipes should be able to handle? I am not able to find one for mye car. It is Volvo v50 d2.
Would this problem make it feel as if i have no power under foot ?
For ALL DPF's is the need to empty a small can/bottle of ANTI crystalising fluid to every time you fill the AD-BLUE tank. This agent IS to stop the ADD-BLUE from making crystals that can & DO block the exhaust/BLUE sensor & cause some very expensive repair bills. For a few £ you can avoid these HUGE bills.
If you dont believe me, then just spill a few drops of AD-BLUE & watch how it crystalises.
Thanks lads, I’ve got a Citroen Berlingo van just gone in limp mode DPF blocked warning. Will check the pipe first. 👍🏾
Thx for a great video! I´m to replace my dpf pressure sensor tomorrow because of second time "soot filter full" and limp mode, first time a guy I know at a volvo shop did a force regen with Volvo Vida, took half a tank of diesel in 35minutes.... will def check the hoses at the same time!
Hi did the pressure sensor work?
Hi, I have a 1.6tdi psa engine mazda 3 bk (mazda, focus, volvo 1.6 diesel) and i often get surging and an error code P024B, often felt to me like an air leak of some sort. Could it be this? I am defo going to look at the hoses from dof. Excellent video thanks. Just have to find the hose now 🙂 👍
Hi mate it certainly a possibility no harm to check
hey, thanks for the advice, please tell me where i can found the sparks on galaxy 2,0d 140 horse power engine cod ufwa.thanks
Thanks for this, I'll check this tomorrow.
A retoricall question, whats the yellow Shepards Crook behind your camera man?
Fantastic advice, now I know what to look for !
Top tip mate 👍
Thanks mate
If only folks could knock a small chisel mark on their dpf's before taking them in. Imagine their faces when youve checked your "new part" and question it😂. And that hose looks nobbly to me unless it's the video?
I've got Peugeot 3008 has depollution faulty and jump go e in limp mode today any ideas to get out limp mode to get it home
ho lo stesso motore su ford focus cmx2005 adesso cercherò quel tubo e controllero se è sano! grazie mille💪🏻👍🏻🔝
Just had this on my 1.6 tdci cmax. Hose had split and put the car into limp mode. Sorted the hose but it wouldn’t come out of limp mode. Apparently it needs to have the values reset on the ECU cos it remembers the old values where’s it got sent into limp mode. Also the hoses are £££. It’s a high temp hose. Replaced it with a high temp fuel line.
⚠️To be fair though, some garages would simply replace the DPF sensor.
Some come with the pipes so in this case the fault would be ignorantly cured because they would have concluded the sensor had gone bad & not realised the actual cause !!!
I have a Peugeot rifter 20 plate my car has give me no warning on the dpf all I got was a air valve intake warning and now the engine is nackerd
I’ve got a message on the scanner vehicle conditions incorrect for dpf regen 😡 I’m now thinking have a look at the pipes - great video Leon 👍🏻
Thanks, but it took you six minutes to say: Check the pipes and tubes. Replace if uncertain.
Then it's the mileage: Around 120 000 km for many cars DPF.
is it just a case of taking that pipe off and fitting new one,is a relearn needed tto do this ?
phewww i bet that was 'exhausting work, Leon 🙂 Thanks for that great video, as ever, keep producing them please, BLESS 😇
Amazing people still around 🎉
All those having DPF and NOX sensors issues stop using cheap diesel
I’ve been using shell V power diesel and all the issues gone no engine check light now 👌
👌👌👌👌 Love to know how you first found that fault as a smoke test would not show it up? 🤔
Nice one ☝️ Bloody sick of rip off so called macaroni s 😅😅😅😅👍🙏🏼❤️💛💚🔙🔜
Hello, thanks for the video. I have Fiat Bravo 2008 1.6 multijet diesel. The car keeps regenerating way too often even after EGR repair and unstable idle repair (which was from the Throttle body electronics). When I scan the DPF I can see that sometimes it is about 31-38% but also very often there is a log which always states 64% and 107k km exactly. Can it be a fault in some DPF sensor or something stuck in the software? The car has power and good fuel consumption. Thanks!
Wow well good tip...nice one fella
Fascinating...thanks for sharing this with us!
Great stuff my friend...always great to see tips like this Leon!
Thanks mate
Hello Sir…
Could a DPF (2017 Jag F-Pace Diesel 2.0 US Spec) leak exhaust into the cabin?
If the filter inside the DPF canister breaks apart, would it sound like set of Headers?
Can one buy the actual filter and replace it inside the canister, or must one buy a complete DPF whole?
My F-Pace had exhaust in the cabin. While driving somewhat hard, the quietness instantly changed to the sound of Headers. I looked at the DPF plumbing while the car was lifted and all the pipes are solid. So, I’m thinking that the the filter inside the DPF exploded.
Your thoughts, PLEASE.
Thank you. Mr DJ
Where is this hose or pipe confused
Ok- but you only have to show the internal crack once, not 10 times, unless your viewer is a member of the Labour party.
😆😆😆
This is a funny video, bending pipes and blowing into them
your buddy looks like he could be a bit of a hoot ?? shifty eye,s .
Lol
What was the customer complaint on this please or did it have a fault code?
Limpo mode no power
Does back box delete create any problem to the turbo on a diesel?
No bud you will be fine
Awesome advice buddy
That an excellent find , good stuff 👍👍, I'll always be checking pipes like that now
Thanks mate
Really good 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Come and fix my Audi please and thank you 😁
Or just delete it with the EGR
Lol it seemed all to familiar, the hoses, the sensor. And it was my model of Mondeo! Hoses were changed by the previous owner to thicker more resistant ones, no wonder why, probably destroyed by the heat/soot like in this case. Very very poor design on Ford's part. But DPF overloaded came on my dash. Hoses robust and ok. One hose seemed to not be fully plugged in, so first thought it was this. But the error came again. Then I saw on OBD diagnostic that my pressure sensor is showing basically constant 104kPa. That's atmospheric pressure! So I unplugged both hoses and still the same pressure. Wires measured ok. Hmm tried to blow with my mouth to one end of the sensor and the pressure in diag changed. So it seems the electric connection or SW if fine. Probably just faulty sensor. So I changed it and boom, 0-5kPa ! Problem solved ! Most likely blocked by soot or simply failed.
Just decided NOT to spend a fortune on a low mileage G350d. Instead, a little petrol powered Suzuki GV will land the job.
1st...
AHAHHAHAH
Boom lol
I founD on diagnostic DPF TRAP Volvo v50 1.6D 2010 . I want check the pipe like video. Thank you
Great video!!! But there is one thing I cannot understand - how come diagnostics didn't show some 'low pressure' error or similar? If you had to discover problem manually, what's the point of pricey diagnostics scanner an other software-hardware?
If you watch my other video on the hue will see exactly why they did not show low pressure
That's what's made this problem very difficult to find
Leon full video on this start to finish please. everyone stay in keep safe SORTED!!!!!!
Full videos coming very soon mate
bodgit and leggit garage cheers Leon can’t wait 👍
I have been told I have DPF problems and its thousands if I cant get it fixed bloody Mazda Demio Diesel wish I had never bought it! Its ruined me financially!
Hello, I have a Ford S-Max 2010, 2 l engine. 6 months ago, the message "engine Malfunctions" appeared. I took the car to a mechanic and changed the DPF, then injection unit particle filter regeneration, then exhaust gas temperature sensor, then exhaust pressure sensor.
After all this it kept giving me an error and I took the car to the Ford representative where they changed it Turbocharger Boost Control Valve, turbo pressure solenoid valve and Turbo Converter Solenoid Vacuum Valve.
After all this, he did a DPF regeneration for me, but the car still gives me an error. The people at the Ford representative advised me to set it on fire.
Can you give me some advice? what can I do to them?
I also bought a tester and put it on the car and it gives me the code P 244C-00 "Exhaust temperature to low for particular filter regeneration.
I just bought my first diesel car, it's a Golf Mk6 1.6 2011 It's done over 220,000kms I'm thinking I should have stuck with petrol.
I have a Sensor Circuit High P0473 Error on my car and the mechanic is like, "All right here goes DPF" without any sort of diagnose...
Cracked Rubber Tube from Turbo
The car saw me an alert of a car and a key. The pc of the mechanic saws problem 1901 sensor dpf.
The turbo of the car doesn't work.
The problems maybe are?
And the solution maybe what?
Give an advice
Thank you
Accent too annoying unlistenable
I hope God blesses you guys good for you trying to help others so good heartedly.. thanks.. got issues with an injector and glow plug fault codes showing up on Dacia Duster but I'm thinking it might be cables or something like that as it's only done just over 30,000 miles
Where is located these pipes I have Volkswagen golf 2013. ? Thank you
Here's a question lads.. I found a totally torn dpf pressure sensor hose (one at front of dpf not rear one).. Would this stop a static regeneration from taking place!? Ford s max with P246C P2463 and P2463-C codes.... Soot accumulation etc.. Limp mode. Can't Static regen. Presume it's this torn/useless hose?
Also Change fuel filter every 15000km the dpf warning light will disappear
hello, i have strange problem wit my passat 1.6 77kw, TDI, nothing on diagnostic shows the problem, ther is no light for dpf, but he starts regeneration every 5 minutes. I changed pressure sensor ( which has only 1 line conected to dpf, and another just goes in nowere), but problem is still on. Injectors are ok, also turbo is ok.?? thanks!
My 2011vwpasst 1.6 tdi drops in power when I hit 120km would that be a vacuum leak or a faulty exhaust pressure sensor.? Thanks
Ones again Leon your are magic!!! ;-)
Lol thanks mate
At my wits end with a 2013 Ford Transit. £2k in so far and still in limp mode. New glo plugs, new DPF. Off the road every other week
Interesting
whats this , father teds garage
Very useful, I have the same problem on my Grand Scenic lll (engine light on, check injection system, pollution system and cruise control) Renault said its the air intake hose at the front of the engine, another says its the 02 sensor at the back of the engine!!
Where are these pipes you are showing please?? Renault Grand Scenic 1.6dci 2014
Just done mine on my Touareg. Dpf light on, limp mode showing no codes. Easy fix delete your dpf and delete from ecu, better fuel economy no issues in the future
Is there a tank for the DPF cleaning liquid in a ford focus 2016 TDCI 1.5? And where it is located? Thank you.
What cleaning fluid do you recommend….? Are the in tank ones any good…? Great video thanks 💪💪💪💪
Some food for though here. I am having repeated dpf warning light issues with my 2011 CRV despite it mainly doing long motorway journeys. The first cleaning lasted 25k miles and then it went again and Honda ?Reset? it and I got 200 miles and nearly home! I had it cleaned again and then 2000 miles. I have had 2 failures after long motorway runs in cold weather and often when I lift off the power from quite a high throttle setting. I shall check pipes and the switch now. I love the car in every respect otherwise but this is getting on my tits now. 🥺
I've got a citroen relay 2016 and I'm getting a p2002
Done a reading on it and I'm getting 0 pressure at idle and max rpm
Its also showing there is 0g of soot in dpf
Eml is on but the dfp light isn't just wonder what this problem could be
Great information mate..
SORTED 💣💣💣
Thanks mate
Would this course a loss off power and hold the car from pulling. I have a 11 plate zafira 1.7 and have a code off 2452 .
This is hopefully going to save me ££££ what r the pipes called I have Nissan Qashqai, thank you 🙏
I have Insignia eco flex 2014 goes to limp mode after front smash central locking don't work no horn and Navi 9000 won't light up ,what can fix it please if turn off on off ignition it does work need to sort it ,guy sold me it never told me was wrote off
Superb video lads, my kids call me redneck dad because of what they call my redneck engineering :-)
Ive just spent alot of money on a new DPF as they said it was done in, but now my engine light has come back on 😢 ffing stressing me
I scrapped my car cause of this 😂 my god well it kept blowing these pipes off and could not figure it out
Hello sir I have a Volvo V 50 2004 2 liter diesel Does that have DPF on it How do you know if you have one
Did you have a part number for the hoses? Just in case. I’m gonna check here soon
Wear is the dpf hose located? Ive had the problem for a year now, constant alarm going, it used to clear after every long drive but as of last week the dpf warning sign has stayed on. I did think it might be something more to do with a pressure sensor etc as it's been happening for so long with no actual driving problems.
Yeah , boost actuator! It happen to me too . I thought I needed a new turbo, but only a couple of dollars for new rubber hose 👍👍👍
cracking tip ????
Lol 😜😛
Very good tip Leon
I would like to see info (what car, age, engine, mileage) on the cars you work on in your videos, it gives an idea on when to expect something like that in this case
Thank you for the great videos
I mate you can get caught very easy with that Because then you would only look for problems with certain mileage and you might forget and miss problems it's best as to always check it regardless of the mileage
And also due to wildly different driving styles it wouldn't play out.
