it's incredibly satisfying seeing all that sludge fire out. Gotta say, when you think how many BMWs are running around with DPF deletes because the owners don't want to fork out to fix it yet you pay £250 to get your cat & DPF renewed this way, it's a no-brainer. Cheaper than getting new parts & it's effectively as good as new
with older cars like this one or BMWs you mention it is often the case of dead catalyst (study how DPF works). So cleaning ceramic trap, thats the part lad here took to cleaner will fix the car for maybe 1000km until it gets clogged up again unable to regenerate. Also would like to see you fork out as you say, 2400 + labor into 3000 car. Maybe you would but many wouldnt, hence the situation. Cheers
@@UPnDOWN i completely agree that dpf “deletes” are not really necessary, but to address the doing it when half blocked thing, I will have to admit to looking into it a few years ago before cleaning really became a thing like it is now and I had a dpf that wouldn’t regenerate for love nor money. I took it to a deleting guy to get a quote and he said I can’t do a delete on a car that is blocked, the cars software won’t accept a change when it’s in that condition and in limp mode, so I don’t know if tech has moved on now but my experience around 8 years ago was if it’s actually blocked it’s too late to delete, maybe things/tech have changed in time or models obv differ etc, so in the end 1100 quid later my 2k worth of car at that time car had a new dpf lol and I still run it to this day :)
Diesel engines and DPFs, two of my favourite things. 😍 Great video as always, thanks! Peugeot and Citroen use Eloys fluid on their diesels as it reduces the temperature needed for the DPF to regenerate. A hotter engine produces more NOx so a cooler engine and exhaust is beneficial for the engine and the environment. I have a 2007 Mondeo Mk4 2.0 TDCi (code QXBA), which is the same engine as fitted to the 407 and C5 of the time. The Ford Mondeo, S-Max, and Galaxy of this era don't use Eloys whereas the Peugeot and Citroen still do. I'm curious about the regeneration process so have actually monitored with Forscan. When my car regenerates the DPF, it over-fuels, closes the EGR, and turns on the glowplugs, pushing the exhaust temperature to over 600c. This can take about 20 minutes or so. The advice is to keep driving but i have found mine can still continue to regenerate even at idle. Sadly they didn't fit a DPF regeneration warning which means many turned their engines off mid regen, which leads to diesel seeping past the piston rings into the oil, causing dilution, the diesel also cleaned the bores which of course leads to issues with the rings on some models. The later Mondeo mk4.5 uses a DW10 (code DW10BTED4) engine which still doesn't have an eloys system. However, it has a vaporiser which injects diesel straight through the DPF, meaning the engine itself doesn't need to get as hot and there's less risk of engine damage. My Mondeo is currently on 224k and the DPF is still good. It's never been off the car either. Let them regen and they're good. As for eloys. Vehicles fitted with this dose the diesel each time the filler flap is opened. There's a small magnet on the filler which triggers a sensor. Those who only put in say ¼ a tank at a time will actually run out of Eloys faster than those who only put in fuel by the tankfull as the system as you say, doesn't know how much fuel has been added nor how much Eloys is remaining. By the way, check out O'Rileys autos as he does a lot of DPF stuff. Interestingly, he's noticed that certain Citroen and Peugeots are programed to give DPF warnings at around 120k. Reason being, PSA deem a DPF to be a service item so they want customers to go back to the dealer to have them replaced but as you've found, they can often be cleaned up and last well beyong this quoted mileage. Happy Christmas and thanks for reading.
6:50 One thing about "every now and then", this is decided by filling up, more specifically, when filling up over half a tank. If you keep putting in 10 quid worth of diesel all the time and keep running the tank almost empty, you won't get any Eolys added and clog the DPF. So make sure you fill it up to full, at least every few fillups.
The reason for this was when the system was first implemented in the 307, owners just kept putting 5 quid of diesel at a time, everytime the fuel cap was taken off the eolys was added to the tank, eventually the fuel was heavily diluted with eolys and the car would no longer start, and the eolys pump would burn out, these faults all occurred during warranty period and PSA had to foot the cost, hence why now the system only adds eolys once a minimum amount of fuel has been added
Yay, Deltic!! Not only did I drive one for my 55th birthday, but the person from the DPS supervising me said "I think we need to clear the exhausts. Pull the handle all the way back but keep to the speed limit". I would have LOVED to have seen the clag come out, even on that one engine...
Cor! a couple of those cleaning machines would make a nice lucrative little bussiness. Thanks for all the entertainment and lessons learnt from your experiences in 2023. Long may it continue. Merry Christmas and a happy new year to you and yours.
about 17:00 you can't see any light through a good DPF, they arent' built up like a Cat, they are in fact shaped like you mentioned a few seconds later.
I almost skipped the video when I realized the topic. So glad I watched.... fascinating tech and explanation thereof. Shout out to Richard B too. Happy New Year from Beantown!
Because it's not the government's choice for me to drive this particular car, in fairness. If they wanted to be fairer, they could tax based on mileage/amount of fuel burned, rather than time. £600+ a year for this is ridiculous.
I remember when the government asked a scientist if they should encourage diesel or LPG. They chose diesel because as the scientist said later ... The German car manufacturers assured me it was cleaner ....
EOLYS fluid is injected into the fuel tank every time you refuel, so a little bit is always being burnt. You might want to check level of Eolys on your C6 as it can be cause of DPF blocking soon as well. The generic PAT/FAP fluid types are horrible. Best off going to dealer or genuine Eolys branded fluid!
Make sure you use 309 filler wire when you weld the stainless flex pipes to the steel exhaust to ensure they don’t crack under continuous movement and temperature changes.
This is yet another reason why I cannot fathom the love of diesels in the UK. A diesel is no good in stop start traffic. It needs the open road. I for one would be quite happy to get rid of most diesel’s & go back to petrol.
It was because the government charged everybody less to run one for a quite a few years, and in many ways they're better. However, in others, they are not.
Good to see some C6 content, even if it lacks C6. Hope you have a good Christmas :D I'm spending mine worrying about my Saab leaking power steering fluid lmao
This was an interesting lesson to learn about. We don't have the amount of diesel cars here in the USA that is around in Europe. What we do have are a lot of diesel trucks and pick ups. Looking forward to seeing the C6 running with the cleaned out exhaust.
Very interesting...! It reminded me why i HATE modern diesel cars. First it was EGT valves blocking up. Then it was the intake, intake runner butterfly valves and intake ports clogging up with tarry cake ( = a MIX of sooth from the EGR and oil vapors coming from the crankcase ventilation) (Seen it all on my BMW 320d) Now you showed us that the insanely expensive sooth cat and DPF system can ALSO become problematic... I'll never buy a modern diesel car ever again.
This is just maintenance of the DPF, as you know nothing lasts forever. I have the 1.6 e-HDI and I've managed to hit 90 mpg in it a couple of times, you wouldn't be able to get near that on the old mechanical diesels but without the DPF and its regen I'd be able to get more but that's another story.
If you have a good driving pattern, those things are none issues. Of course, I can agree older diesels were less suceptible to sub-optimal driving pattern running.
Off the subject of the c6. Hope you and the family have a great Christmas and New Year. Great channel, and hope your channel grows bigger next year. Best wishes.
on the subject of ash buildup - You can reduce the rates at which the DPF ashes up with decent quality diesel-specific low ash oils and regular maintenance schedules. Also, inspecting for excess blow-by from the PCV or oil consumption on higher mileage engines is a smart idea if you want the DPF to last. ash buildup occurs when the engine burns its oil, as some of the additives will form an inert ash when combusted. Besides that, the soot's easy to get shot of. you can either trigger a static regen with a scan tool, or pootle around a bit to get the engine up to temperature, then 30 minutes in 4th down any motorway *that's not the M25 because it's a complete and utter car-park at the best of times* should do the trick since that will allow the engine to reach the correct EGTs to be able to at least actively regen. Extra points if you're mostly uphill for the duration of the regen run as the added load will increase the EGTs further.
dpf`s have indeed bulkheads, not through and through... as long as the regen works it burns out the soot, but the ash remains and that needs external cleaning after somuch time... also with the built in eolys system you get more of the reddish color when cleaning it out...
One thing I was taught is that a DPF should never need replacing, they can always be cleaned (unless of course the insides have broken up). I wish all DPFs were as easy to remove as the C6's though! On a Fiat Ducato you have to remove the engine. Nice to see the professional cleaning process too, I always wondered how that worked. I guess our way of shoving cleaner in them and then jet washing them out isn't far wrong! I'd guess that Peugeots bleed red from the DPF because of the EOLYS fluid, that's a dark red/brown colour. Nasty stuff.
On the Euro 6 Alexander Dennis Enviro 400 MMC, the DPF is an element you can remove from the exhaust by just two V-bands. The DPF element is meant to be cleaned once a year. Unfortunately, because of it's placement, it's an 8 hour job to replace the DPF element.
Subscribed from Indianapolis, IN. USA. Enjoying your content. A formula here on Autos seems to be MORE. Every nook and cranny, 50mins to 1:20. ♥ Hubnuts. Easily catching up.
Dam that got it clean, That is a top tip getting them cleaned like that. I bet the C6 will have all it's ponies at full gallop again when its back together.
You won’t see any light through even a clean new dpf because the tubes cast in each end of the ceramic overlap but do not meet. The gases pass through the porous ceramic from from one tube to its adjacent neighbours. The soot is trapped to be burned later. Each successive burn leaves a little ash depending on the quality of the fuel used. Eventually the ash builds up to choke the filter. Mild acids dissolve the ash.
The DPF is mostly to do with reducing NOx emissions. More or less or it is produced based on the combustion temperature. I can't remember if it's higher combustion temperatures mean less NOx or more, but either way, that's what the purpose of making the DPF stay at a certain temperature.
I have to admit I did a fair amount of short journeies in her. That said, She use to get at least 2 long blasts down to the south eastern part of France, over 400 miles each way and would cruise at 80 for most of it. I think the Eolys was filled up at about 100K
The other idea of the high temperature burn off in the DPF. Is some magic chemistry so the Regened ash is less harmful than the normal ash. (Well that's what i was told years ago)
Yes, in theory, the black soot (which is mostly just carbon) gets burned and turns directly to CO2, an invisible gas. It will always leave some unburnable residue though. Hence the state of this filter. For the mileage this car has done, they look in really good condition!
Eolys (cerium-oxide based compound, nasty) lowers the necessary temperature required to burn off soot, and AdBlue (1/3 man-made urea mixed with 2/3 deionised water, much less nasty) decomposes oxides of nitrogen into nitrogen and water. Eolys is dosed into the fuel and there's an audible ticking sound after filling up. I was wondering if having both solutions (i.e. like BlueHDi) would be theoretically more reliable, but if cerium supposedly stays in the filter, like ash, would the DPF need clearing out earlier? I imagine that with newer cars, you'd need to investigate why a DPF got that blocked in the first place as it's likely to happen again (literally rinse and repeat), but given the C6's age and mileage, I'm not really too surprised. Oh, Merry Christmas.
I've got an '09 Passat tdi with nearly 130k miles on the clock; I take it for a good run on the m'way every couple of weeks or so and generally try to keep short journeys to a bare minimum (I have additional means of getting around). Seems to keep everything sweet. I 'lost' an engine (Mazda 6) a few years back due to ignorance about DPF management. Once bitten...
Alledgedly, though the guy who cleaned it didn't seem to think so. Motorway use definitely more important than which type of fuel to use. I'm now using normal diesel on long runs, and putting V-power diesel in every other top-up for short town work. Doubt it'll do anything except cost me money, but you never know...
The red splodge at the end makes it look like an amputated leg! Or Is that just me? It reminds me a bit of a mobile phone or computer. It goes through life picking up all kinds of data clag, but you can't see it and only resetting your phone gets rid of it.
I think getting the regen temp in the exhaust down to around 400° is probably a tactic to reduce NOx emissions, there's a known peak at around 600° that just so happens to also be about the point that soot needs to burn off. Citroen must have taken the trade off that you'll need to do a proper clean at around 150k miles in exchange for meeting then current emissions limits.
If I understood correctly, the DPF collects the soot and small particles (less than 2.5 nm), and when it's cleaned or regenerated, those particles go away as chunks, not small ones that are the really dangerous ones.
I use extraction sockets on the exhaust bolts and quite unexpectedly they do come ondone. I dont know what it is but PSA has very good exhaust fixings. Broke one but thatwas my fault for using the wrong tool a first.
Cats you can see through the side walls are the catalyst and exchanges the oxides, DPFs are filters so the holes at the front are the blocked holes at the back, the exhaust travels sideways through the channel to the open channel at the back of the DPF (splice your fingers together the exhaust travels sideway from left to right arm to arm) cleaning is a specialist task OR a pressure washer up the back end (seal the pressure washer to the back end and pump the hole pressure in)
Every time I see DPF and Cat cleaning I can't believe we are breathing that crap. Because some of it escapes and "some" multiplied by millions of cars is insane. And in the past it was straight out. Vroom vroom noises are still fun though. 😌
Wow! Result! Good luck with the welding. I note that one of the flexis is set up to be slightly longer than the other, possibly so that the clamps don't interfere with each other. Should go like a rocket now. Maybe HubNut needs to pay a visit.
At 17:50 the sound is wonderful: BANG. BANG. ... thunk. TING. The rhythm is perfect, and it inspires me to listen to the whole audio without the picture. Might be fodder for the Institute of Contemporary Arts.
Much learning, very knowledge! After now seeing the whole video, got to wonder how those are good for emissions, are they just holding onto all the muck which is then replaced/cleaned. Then releasing all the clag that's bound up in at places like this. But then surely that muck has to be disposed of in some way, so making the process even more long winded, requiring more steps, must make it worse for the environment? As in the energy used to reclaim them. That's not counting what the car manufacturers do with any blocked ones they change, they must have to be disposed of in a planet hugging way. Just doesn't add up.
I think all things considered, they do more good than bad, but if you burn fossil fuels, you'll never be able to stop the harm to the planet entirely. All you can do is minimise it. I'm learning more about them all the time, and I certainly wouldn't 'delete' it now I've seen what it held onto.
If the DPF is missing visually, it's an instant fail. If it's drilled out and mapped out of the software, in theory it'd pass, but I'm not sure if there would be an emissions issue.
Merry Christmas Rich! That was very educational. We've all heard of the mystical DPF but how many know what it looks like and how it operates? Can't beat a video with some pure filth in it!
You won't see light through it. It it designed to force the gases at high resistance so those Chambers are not straight through but go back and forth to maximise the contact with the filter. It also aids buildup of heat. (John Smith)
Mmmmm, Deltic. How these things aren't more well known I do not know. Very cool engineering. Diesel soot isn't nice, true but when I'm being tailgated driving my mk1 Fabia vRS dropping a couple of gears and leaving a smokescreen is very satisfying! What I didnt realise is how the DPF gets up to light-off temperature, the ECU injects extra fuel at specific times to allow hot fuel into the catalyst to raise the temperature in the exhaust. I had a cat fail causing the DPF not to reach light-off. I have a lot of experiance running vans with EOLYS and yes, we topped them up around 100k miles and its nasty stuff (gloves firmly on!) but also theres a counter in the ECU that after a certain number of EOLYS injections will announce the DPF needs replacing. This counter can be reset is all i'll say..... (Apologies for the wordy response, I've had a beer...) Edit: That DPF clean seems amazing!
Vehicles obviously differ, so this isn’t a general rule of thumb for all vehicles, my 2007 Volvo V50 1.6D ( from the time of ford ownership so like the focus 1.6 tdci it is a PSA HDI engine) had a new dpf then 8 months later the warning came on that EOLYS was low and needed topping up, both completely different “warnings” Like I said no doubt what you said is absolutely true, but it’s far from a rule of thumb 😊
@garygreenwood3995 Absolutely! It varies enormously based on all sorts of factors, especially with that 1.6 diesel as it goes in absolutely everything seemingly. Very versatile engine tbh, seemed much better than the 1.5 that replaced, mind you, that's comparing late generation 1.6 with relatively early 1.5, so not entirely fair!
@@chrisdowns1987 yeah the 1.6 hdi gets a hard time from many, but like most frowned upon engines it’s people who never had one from new or nearly new and also like most frowned upon engines they may have just had experience of a badly maintained one, my Volvo over 180 k now and is still a great little Trojan of an engine, now don’t get me wrong in the last couple of years it’s had a few wee things that every engine needs, cambelt swaps etc and I did have a buggar of a time with a chuffing injector last year that was a devil to get out to replace the copper washer, and I think a turbo may be on the cards next year but for now I’m enjoying an almost supercharger type whine lol, but personally I love that engine in anything, back in the day had a pug company van and loved that engine in that too, economical as hell and can still chase the pigeons when need be :) PS I’ve two hillman imps too that I’ve owned for decades ( with original engines not transplants lol) and I’ve never cooked one or changed a head gasket either lol :D
@garygreenwood3995 🤣 Not had many injector blow by issues on them, tbh but I've done more cambelt & waterpump changes than I can remember! 180k on the original turbo is pretty damned good 👌
I had to deal with Citroen DPFs and was surprised how easy they came off. I’m on my 4th Picasso with only 58k miles on so hopefully that DPF should last a while. Andrew
Never Stellantis (psa) cars uses both eolys and adblue. I work at a Peugeot dealer and you will have a fair bit of luck to remove the pipe of the dpf even on cars thats is a couple of years old. Usually the snap or the threads are gone (they are staniless)
The video insert of the 'Belching Bertha' diseasal heritage locomotive passing through, with that poor lady and her kid in the pushchair on the opposite platform vainly trying to fan the fumes away makes me wonder how such air pollution can ever be acceptable. 🙄
I can't imagine how much you must be looking forward to the test drive when it's back on the road, would that be clickbait? I'll have an Adblue cocktail to celebrate anyway. Could you see light through it afterward? Thanks for sharing a Load of Cr@p with us and best wishes of the season to all.
Pleased to see you are not deleting your DPF. I dont want to see more people suffer from silly schemes like ULEZ which would probably not even exist if everyones car ran as designed.
Nope, I figured it stopped all that shite going into the air, therefore it serves a purpose. And you're right...people cheat the systems and then moan when the rules get changed.
Indeed! Thank you! Lots of people don’t understand me when I say that. I have lived between France and the UK for 30 years and have visited 80 countries. I hope that’s helped give a bit of perspective. I’m my experience the UK feels as European as Japan feels Asian. Or as Malta feels European. It’s one of those things that once you’ve heard you can’t unhear. I always feel the UK would get along better with its geographically and culturally closest neighbours if Brits realised where they actually were in the world. I get especially frustrated when broadsheet newspapers do it. And I did know what you meant; of course I did. I just think it’s more accurate to say ‘in mainland Europe’ or ‘on the continent’ instead. Although that expression comes with it’s lot of issues too; when Corsicans say ‘sur le continent’ it’s meant to be extremely disparaging towards mainland France, for example…
The only guy that knows facts about DPF is O'Rileys Autos on you tube there are so many variants and those two small tubes calculate offset pressure in DPF enabling ecu to calculate and determine when to activate regen .
I never had any trouble with my focus 1.6tdci dpf however I ragged the thing to hell assuming probably helped get the temps up in the dpf. Mine was 2012 so didn't have eolys fluid I believe a diesel injector pre dpf which most modern fords use now. However I still wouldn't buy another car with one unless I really have to I like my pre dpf smax. Apparently it was an option at that age I wonder if there was anyone insane enough to pay for the extra. I watch a lot of the orielys autos video and to be fair most the problems are pretty common sense but it's insane how many garages get it wrong. My sister in law's focus constantly had dpf issues in the end we chopped it in for a petrol to save the hassle. Having health problems for last year or so I just didn't have it in me to try and sort it myself.
@@HA05GER Well more stuff is more to break, thats true. However, at least if you do lots of miles in not too many years, it seems to be fine. I am involved in running a fleet of Taxis and I havent really seen any problems of note until they are sold on at 300k miles or so.
@@HA05GER We dont have any such distinction where I am at, we use whatever fuel we can get, and always did. Currently we use diesel fuel with 30% renewables mixed in, as is the law here. Earlier we have used fuel with as much as 100% renewables because of contract stipulations. No differences of note. All in all, I seriously doubt there is much distinction between "supermarket fuel" and anything else chemically either if you are in western europe, as far as I know, these things are pretty regulated...
Dpf is crap technology in my opinion. My Honda CRV (2011) has one mounted on the front of the engine. It is intended to periodically ramp up to 700 deg C with extra fuel burn when the differential pressure reaches a certain value. Sadly this temperature is often not achieved even at motorway cruising speed in cold weather due to the airstream behind the radiator! I have had the car default to limp home mode after a 200 motorway blast several times! After two expensive forced regens, I invested in an obd machine to do it myself. I used aerosols of dpf cleaner sprayed down the upstream pressure sensor duct into a warm dpf. Worked a treat every smoky time! I wish I was clever enough to do the audit maths to establish if the continuous 3-5mpg extra fuel consumption was better or worse for the environment than the particulates that are only an issue in conurbations. Most of the clean technology carries a significant CO2 footprint price tag. Funny old world we enjoy since they invented “the science”! These guys look a whole magnitude better in the job they do. 👍
I feel happier knowing I'm doing what I can for the planet tbh , even if it's not much. The DPF does work well, as previous MoT emissions tests have shown.
I spent over 10 years braking 1000s of Citroën and Peugeot cars that has let me see the worst and the way additive is guesstimated and complicated to deal with even if you know what you are doing has killed way to many cars
Peugeot used to use adblue and end Eloys in the first generation of 3008. The common problem with those was th3 tank had a habit of failing as mi e did 18 months old! I think these days they just use adblue and it is squirted into the system every time the engine starts. So, if you turn your stop/start off then you allow potentially the problem to build earlier.

A 3 litre tank holds 200 15ml doses (3000/15). If 15ml is used per 100 litres of fuel that's 20,000 litres of fuel per eloys tankful ... Or 4,401 gallons (20,000/4.544, where 4.544 = 568ml per pint * 8 pint oer gallon). At 30 mpg this would need the eloys tank filling at 132k miles! (spot the deliberate mistake - this needs recalculating based on 2.3 litres if the refill warning comes on when 700ml is left ... That works out at a refill at about 100k miles)
Yeah, most cars seem to run out of pat fluid around 90-100k. But can be a lot less if your a person that never fill their tank and puts just £20 a time in. It injects it into the fuel tank and it's a dumb system that doesn't know how much fuel you put in, it only know that you have open the fuel cap. So assumes you have filled it.
"Risk of DPF blockage." Citroen software clearly operating in understatement mode.
I think that ship had sailed 😆
Merd! Quite literally. I hate diesel even more now.
Happy Christmas everyone.
A taxi C5 i drove said it had a "AdBlue issue". The AdBlue injector was literally melted open and it was smoking white like a sentinel steam lorry
@@grossteilfahrer well there was indeed an issue with the adblue injector. I don't see the issue. The computer just didn't want to annoy you too much.
it's incredibly satisfying seeing all that sludge fire out. Gotta say, when you think how many BMWs are running around with DPF deletes because the owners don't want to fork out to fix it yet you pay £250 to get your cat & DPF renewed this way, it's a no-brainer. Cheaper than getting new parts & it's effectively as good as new
with older cars like this one or BMWs you mention it is often the case of dead catalyst (study how DPF works). So cleaning ceramic trap, thats the part lad here took to cleaner will fix the car for maybe 1000km until it gets clogged up again unable to regenerate. Also would like to see you fork out as you say, 2400 + labor into 3000 car. Maybe you would but many wouldnt, hence the situation. Cheers

@@UPnDOWN i completely agree that dpf “deletes” are not really necessary, but to address the doing it when half blocked thing, I will have to admit to looking into it a few years ago before cleaning really became a thing like it is now and I had a dpf that wouldn’t regenerate for love nor money. I took it to a deleting guy to get a quote and he said I can’t do a delete on a car that is blocked, the cars software won’t accept a change when it’s in that condition and in limp mode, so I don’t know if tech has moved on now but my experience around 8 years ago was if it’s actually blocked it’s too late to delete, maybe things/tech have changed in time or models obv differ etc, so in the end 1100 quid later my 2k worth of car at that time car had a new dpf lol and I still run it to this day :)
Diesel engines and DPFs, two of my favourite things. 😍 Great video as always, thanks!
Peugeot and Citroen use Eloys fluid on their diesels as it reduces the temperature needed for the DPF to regenerate. A hotter engine produces more NOx so a cooler engine and exhaust is beneficial for the engine and the environment.
I have a 2007 Mondeo Mk4 2.0 TDCi (code QXBA), which is the same engine as fitted to the 407 and C5 of the time. The Ford Mondeo, S-Max, and Galaxy of this era don't use Eloys whereas the Peugeot and Citroen still do. I'm curious about the regeneration process so have actually monitored with Forscan. When my car regenerates the DPF, it over-fuels, closes the EGR, and turns on the glowplugs, pushing the exhaust temperature to over 600c. This can take about 20 minutes or so. The advice is to keep driving but i have found mine can still continue to regenerate even at idle. Sadly they didn't fit a DPF regeneration warning which means many turned their engines off mid regen, which leads to diesel seeping past the piston rings into the oil, causing dilution, the diesel also cleaned the bores which of course leads to issues with the rings on some models. The later Mondeo mk4.5 uses a DW10 (code DW10BTED4) engine which still doesn't have an eloys system. However, it has a vaporiser which injects diesel straight through the DPF, meaning the engine itself doesn't need to get as hot and there's less risk of engine damage.
My Mondeo is currently on 224k and the DPF is still good. It's never been off the car either. Let them regen and they're good.
As for eloys. Vehicles fitted with this dose the diesel each time the filler flap is opened. There's a small magnet on the filler which triggers a sensor. Those who only put in say ¼ a tank at a time will actually run out of Eloys faster than those who only put in fuel by the tankfull as the system as you say, doesn't know how much fuel has been added nor how much Eloys is remaining.
By the way, check out O'Rileys autos as he does a lot of DPF stuff. Interestingly, he's noticed that certain Citroen and Peugeots are programed to give DPF warnings at around 120k. Reason being, PSA deem a DPF to be a service item so they want customers to go back to the dealer to have them replaced but as you've found, they can often be cleaned up and last well beyong this quoted mileage.
Happy Christmas and thanks for reading.

6:50 One thing about "every now and then", this is decided by filling up, more specifically, when filling up over half a tank. If you keep putting in 10 quid worth of diesel all the time and keep running the tank almost empty, you won't get any Eolys added and clog the DPF. So make sure you fill it up to full, at least every few fillups.
Ahhh, really? I did not know that!
The reason for this was when the system was first implemented in the 307, owners just kept putting 5 quid of diesel at a time, everytime the fuel cap was taken off the eolys was added to the tank, eventually the fuel was heavily diluted with eolys and the car would no longer start, and the eolys pump would burn out, these faults all occurred during warranty period and PSA had to foot the cost, hence why now the system only adds eolys once a minimum amount of fuel has been added
also make sure you are using proper low ash oil
Can't wait for the next video to see how it runs
Yay, Deltic!! Not only did I drive one for my 55th birthday, but the person from the DPS supervising me said "I think we need to clear the exhausts. Pull the handle all the way back but keep to the speed limit". I would have LOVED to have seen the clag come out, even on that one engine...
That's something I need to do!
Cor! a couple of those cleaning machines would make a nice lucrative little bussiness.
Thanks for all the entertainment and lessons learnt from your experiences in 2023.
Long may it continue.
Merry Christmas and a happy new year to you and yours.

Thanks, hope you have a good one too.

Looking forward to seeing this get straight on the rolling road as soon as you’ve put it all back together again
I'll need to soon, as all is still not well with the C6...
Wow, well I haven’t see that before, thanks Rich👌🏻
I almost skipped the video when I realized the topic. So glad I watched.... fascinating tech and explanation thereof. Shout out to Richard B too. Happy New Year from Beantown!
I've learned to always give things a go, regardless of preconceptions. Then you decide whether it was worth your time or not. HNY to you too.
Why isn't a dpf clean done free by the government if they're genuine about cleaning the environment?
Because it's not the government's choice for me to drive this particular car, in fairness. If they wanted to be fairer, they could tax based on mileage/amount of fuel burned, rather than time. £600+ a year for this is ridiculous.
I remember when the government asked a scientist if they should encourage diesel or LPG. They chose diesel because as the scientist said later ... The German car manufacturers assured me it was cleaner ....
@@UPnDOWNthey do.....its called fuel duty 🙄
EOLYS fluid is injected into the fuel tank every time you refuel, so a little bit is always being burnt. You might want to check level of Eolys on your C6 as it can be cause of DPF blocking soon as well. The generic PAT/FAP fluid types are horrible. Best off going to dealer or genuine Eolys branded fluid!
Make sure you use 309 filler wire when you weld the stainless flex pipes to the steel exhaust to ensure they don’t crack under continuous movement and temperature changes.
I was wondering about that, I've never attempted to weld normal steel to stainless.
Technically, you're correct. That said, I've never actually used it, and I've never had a problem!
This is yet another reason why I cannot fathom the love of diesels in the UK. A diesel is no good in stop start traffic. It needs the open road. I for one would be quite happy to get rid of most diesel’s & go back to petrol.
It was because the government charged everybody less to run one for a quite a few years, and in many ways they're better. However, in others, they are not.
Good to see some C6 content, even if it lacks C6. Hope you have a good Christmas :D I'm spending mine worrying about my Saab leaking power steering fluid lmao

This was an interesting lesson to learn about. We don't have the amount of diesel cars here in the USA that is around in Europe. What we do have are a lot of diesel trucks and pick ups. Looking forward to seeing the C6 running with the cleaned out exhaust.

Same!
That was the cars personality chip kicking in, it trusts Rich to know what hes doing, if it had been me those bolts would never have budged.😂
Very interesting...!
It reminded me why i HATE modern diesel cars.
First it was EGT valves blocking up.
Then it was the intake, intake runner butterfly valves and intake ports clogging up with tarry cake ( = a MIX of sooth from the EGR and oil vapors coming from the crankcase ventilation)
(Seen it all on my BMW 320d)
Now you showed us that the insanely expensive sooth cat and DPF system can ALSO become problematic...
I'll never buy a modern diesel car ever again.
This is just maintenance of the DPF, as you know nothing lasts forever.
I have the 1.6 e-HDI and I've managed to hit 90 mpg in it a couple of times, you wouldn't be able to get near that on the old mechanical diesels but without the DPF and its regen I'd be able to get more but that's another story.
If you have a good driving pattern, those things are none issues. Of course, I can agree older diesels were less suceptible to sub-optimal driving pattern running.
To be fair, this car is asked to work in a way that it's really not suited to. It's also got to 164,000 miles and just had its first DPF issue.
Although I believe it's suffered EGR issues in the past, before I owned it.
Learned something useful (again!). Thanks for the video.
Off the subject of the c6. Hope you and the family have a great Christmas and New Year. Great channel, and hope your channel grows bigger next year. Best wishes.
Thanks, you too!
on the subject of ash buildup -
You can reduce the rates at which the DPF ashes up with decent quality diesel-specific low ash oils and regular maintenance schedules. Also, inspecting for excess blow-by from the PCV or oil consumption on higher mileage engines is a smart idea if you want the DPF to last. ash buildup occurs when the engine burns its oil, as some of the additives will form an inert ash when combusted.
Besides that, the soot's easy to get shot of. you can either trigger a static regen with a scan tool, or pootle around a bit to get the engine up to temperature, then 30 minutes in 4th down any motorway *that's not the M25 because it's a complete and utter car-park at the best of times* should do the trick since that will allow the engine to reach the correct EGTs to be able to at least actively regen. Extra points if you're mostly uphill for the duration of the regen run as the added load will increase the EGTs further.
I'd heard about the fuels before, but admittedly had let my wallet take over due to the cost.
dpf`s have indeed bulkheads, not through and through... as long as the regen works it burns out the soot, but the ash remains and that needs external cleaning after somuch time... also with the built in eolys system you get more of the reddish color when cleaning it out...
This is the weirdest Christmas video I've watched so far! Merry Christmas, sir.
Same to you!
Looks cool when it comes out of a deltic! That's such a real ale thing to say!
Well, it does!
One thing I was taught is that a DPF should never need replacing, they can always be cleaned (unless of course the insides have broken up). I wish all DPFs were as easy to remove as the C6's though! On a Fiat Ducato you have to remove the engine. Nice to see the professional cleaning process too, I always wondered how that worked. I guess our way of shoving cleaner in them and then jet washing them out isn't far wrong!
I'd guess that Peugeots bleed red from the DPF because of the EOLYS fluid, that's a dark red/brown colour. Nasty stuff.
I did wonder if it was cos of the EOLYS fluid. Been told not to drink it...
On the Euro 6 Alexander Dennis Enviro 400 MMC, the DPF is an element you can remove from the exhaust by just two V-bands. The DPF element is meant to be cleaned once a year. Unfortunately, because of it's placement, it's an 8 hour job to replace the DPF element.

Welcome Tom!
Wow that looks really nice!
Dam that got it clean, That is a top tip getting them cleaned like that. I bet the C6 will have all it's ponies at full gallop again when its back together.
You won’t see any light through even a clean new dpf because the tubes cast in each end of the ceramic overlap but do not meet. The gases pass through the porous ceramic from from one tube to its adjacent neighbours. The soot is trapped to be burned later. Each successive burn leaves a little ash depending on the quality of the fuel used. Eventually the ash builds up to choke the filter. Mild acids dissolve the ash.
The DPF is mostly to do with reducing NOx emissions. More or less or it is produced based on the combustion temperature. I can't remember if it's higher combustion temperatures mean less NOx or more, but either way, that's what the purpose of making the DPF stay at a certain temperature.
Ad blue and the EGR reduce the NOx emissions. DPF reduce particulate matter.
EGR reduces combustion temperatures to reduce NOx.
Quite possibly. My knowledge of these things is basic, but haz hammer can weld
Merry Christmas old boy.
You too
I have to admit I did a fair amount of short journeies in her. That said, She use to get at least 2 long blasts down to the south eastern part of France, over 400 miles each way and would cruise at 80 for most of it. I think the Eolys was filled up at about 100K
The other idea of the high temperature burn off in the DPF. Is some magic chemistry so the Regened ash is less harmful than the normal ash. (Well that's what i was told years ago)
Makes sense.
Yes, in theory, the black soot (which is mostly just carbon) gets burned and turns directly to CO2, an invisible gas. It will always leave some unburnable residue though. Hence the state of this filter. For the mileage this car has done, they look in really good condition!
Eolys (cerium-oxide based compound, nasty) lowers the necessary temperature required to burn off soot, and AdBlue (1/3 man-made urea mixed with 2/3 deionised water, much less nasty) decomposes oxides of nitrogen into nitrogen and water. Eolys is dosed into the fuel and there's an audible ticking sound after filling up. I was wondering if having both solutions (i.e. like BlueHDi) would be theoretically more reliable, but if cerium supposedly stays in the filter, like ash, would the DPF need clearing out earlier?
I imagine that with newer cars, you'd need to investigate why a DPF got that blocked in the first place as it's likely to happen again (literally rinse and repeat), but given the C6's age and mileage, I'm not really too surprised.
Oh, Merry Christmas.
Quite a few surprises to be had in this upload.
I've got an '09 Passat tdi with nearly 130k miles on the clock; I take it for a good run on the m'way every couple of weeks or so and generally try to keep short journeys to a bare minimum (I have additional means of getting around). Seems to keep everything sweet. I 'lost' an engine (Mazda 6) a few years back due to ignorance about DPF management. Once bitten...
That's unbelievable. Could that blockage be negated by using better quality fuel and/or more motorway use?
Alledgedly, though the guy who cleaned it didn't seem to think so. Motorway use definitely more important than which type of fuel to use. I'm now using normal diesel on long runs, and putting V-power diesel in every other top-up for short town work. Doubt it'll do anything except cost me money, but you never know...
Blimey, That was really mucky
My previous C4 had this system, gave me no problems but had to get the fluid replaced.
My current C4 uses AdBlue.
The red splodge at the end makes it look like an amputated leg!
Or Is that just me?
It reminds me a bit of a mobile phone or computer. It goes through life picking up all kinds of data clag, but you can't see it and only resetting your phone gets rid of it.
I think getting the regen temp in the exhaust down to around 400° is probably a tactic to reduce NOx emissions, there's a known peak at around 600° that just so happens to also be about the point that soot needs to burn off. Citroen must have taken the trade off that you'll need to do a proper clean at around 150k miles in exchange for meeting then current emissions limits.
I dont know, newer cars that supposedly would fulfill at least as stringent rules use the heating method...
If I understood correctly, the DPF collects the soot and small particles (less than 2.5 nm), and when it's cleaned or regenerated, those particles go away as chunks, not small ones that are the really dangerous ones.
Makes sense.
I use extraction sockets on the exhaust bolts and quite unexpectedly they do come ondone. I dont know what it is but PSA has very good exhaust fixings. Broke one but thatwas my fault for using the wrong tool a first.
Merry Christmas to you and family
Same to you!
Cats you can see through the side walls are the catalyst and exchanges the oxides, DPFs are filters so the holes at the front are the blocked holes at the back, the exhaust travels sideways through the channel to the open channel at the back of the DPF (splice your fingers together the exhaust travels sideway from left to right arm to arm) cleaning is a specialist task OR a pressure washer up the back end (seal the pressure washer to the back end and pump the hole pressure in)
Makes sense.
Every time I see DPF and Cat cleaning I can't believe we are breathing that crap. Because some of it escapes and "some" multiplied by millions of cars is insane. And in the past it was straight out. Vroom vroom noises are still fun though. 😌
Yeah, I felt much more positive about it having a DPF when I saw the buckets of sludge.
Wow! Result! Good luck with the welding. I note that one of the flexis is set up to be slightly longer than the other, possibly so that the clamps don't interfere with each other. Should go like a rocket now. Maybe HubNut needs to pay a visit.
One side is longer than the other, but it's the piece of pipe on the end that governs that, not the flexi.
Fascinating video 👏👍

@@UPnDOWN And the LMH Orchestra.
Much learning, very knowledge!
After now seeing the whole video, got to wonder how those are good for emissions, are they just holding onto all the muck which is then replaced/cleaned. Then releasing all the clag that's bound up in at places like this. But then surely that muck has to be disposed of in some way, so making the process even more long winded, requiring more steps, must make it worse for the environment? As in the energy used to reclaim them. That's not counting what the car manufacturers do with any blocked ones they change, they must have to be disposed of in a planet hugging way.
Just doesn't add up.
I think all things considered, they do more good than bad, but if you burn fossil fuels, you'll never be able to stop the harm to the planet entirely. All you can do is minimise it. I'm learning more about them all the time, and I certainly wouldn't 'delete' it now I've seen what it held onto.
If deleted with software and replaced with a normal CAT, would the MOT know if the car is registered with DPF?
If the DPF is missing visually, it's an instant fail. If it's drilled out and mapped out of the software, in theory it'd pass, but I'm not sure if there would be an emissions issue.
Merry Christmas Rich!
That was very educational. We've all heard of the mystical DPF but how many know what it looks like and how it operates?
Can't beat a video with some pure filth in it!
Thanks, hope you had a good one and thanks for your support
You won't see light through it. It it designed to force the gases at high resistance so those Chambers are not straight through but go back and forth to maximise the contact with the filter. It also aids buildup of heat. (John Smith)
Very interesting.
Another good video happy Christmas 🤶🎅🎊🎊🎊🎉🎉🎉🎉🎉👏👏👍👍⭐️⭐️
Same to you
Mmmmm, Deltic. How these things aren't more well known I do not know. Very cool engineering. Diesel soot isn't nice, true but when I'm being tailgated driving my mk1 Fabia vRS dropping a couple of gears and leaving a smokescreen is very satisfying! What I didnt realise is how the DPF gets up to light-off temperature, the ECU injects extra fuel at specific times to allow hot fuel into the catalyst to raise the temperature in the exhaust. I had a cat fail causing the DPF not to reach light-off. I have a lot of experiance running vans with EOLYS and yes, we topped them up around 100k miles and its nasty stuff (gloves firmly on!) but also theres a counter in the ECU that after a certain number of EOLYS injections will announce the DPF needs replacing. This counter can be reset is all i'll say..... (Apologies for the wordy response, I've had a beer...)
Edit: That DPF clean seems amazing!
Vehicles obviously differ, so this isn’t a general rule of thumb for all vehicles, my 2007 Volvo V50 1.6D ( from the time of ford ownership so like the focus 1.6 tdci it is a PSA HDI engine) had a new dpf then 8 months later the warning came on that EOLYS was low and needed topping up, both completely different “warnings” Like I said no doubt what you said is absolutely true, but it’s far from a rule of thumb 😊
@garygreenwood3995 Absolutely! It varies enormously based on all sorts of factors, especially with that 1.6 diesel as it goes in absolutely everything seemingly. Very versatile engine tbh, seemed much better than the 1.5 that replaced, mind you, that's comparing late generation 1.6 with relatively early 1.5, so not entirely fair!
@@chrisdowns1987 yeah the 1.6 hdi gets a hard time from many, but like most frowned upon engines it’s people who never had one from new or nearly new and also like most frowned upon engines they may have just had experience of a badly maintained one, my Volvo over 180 k now and is still a great little Trojan of an engine, now don’t get me wrong in the last couple of years it’s had a few wee things that every engine needs, cambelt swaps etc and I did have a buggar of a time with a chuffing injector last year that was a devil to get out to replace the copper washer, and I think a turbo may be on the cards next year but for now I’m enjoying an almost supercharger type whine lol, but personally I love that engine in anything, back in the day had a pug company van and loved that engine in that too, economical as hell and can still chase the pigeons when need be :) PS I’ve two hillman imps too that I’ve owned for decades ( with original engines not transplants lol) and I’ve never cooked one or changed a head gasket either lol :D
@garygreenwood3995 🤣 Not had many injector blow by issues on them, tbh but I've done more cambelt & waterpump changes than I can remember! 180k on the original turbo is pretty damned good 👌
I had to deal with Citroen DPFs and was surprised how easy they came off. I’m on my 4th Picasso with only 58k miles on so hopefully that DPF should last a while. Andrew
Never Stellantis (psa) cars uses both eolys and adblue. I work at a Peugeot dealer and you will have a fair bit of luck to remove the pipe of the dpf even on cars thats is a couple of years old.

@@UPnDOWN No but many don't share facts as they just want to sell you Temporary quick fixes
Make sure you tell the car it's had a new dpf fitted in the ECU
I never had any trouble with my focus 1.6tdci dpf however I ragged the thing to hell assuming probably helped get the temps up in the dpf. Mine was 2012 so didn't have eolys fluid I believe a diesel injector pre dpf which most modern fords use now. However I still wouldn't buy another car with one unless I really have to I like my pre dpf smax. Apparently it was an option at that age I wonder if there was anyone insane enough to pay for the extra. I watch a lot of the orielys autos video and to be fair most the problems are pretty common sense but it's insane how many garages get it wrong. My sister in law's focus constantly had dpf issues in the end we chopped it in for a petrol to save the hassle. Having health problems for last year or so I just didn't have it in me to try and sort it myself.
DPF is fine for many, many miles if you have a good driving pattern. 300k+ miles.
@@GoldenCroc the DPf itself yeh but everything around it tends to not last as well be it pressure sensors or additive injectors.
@@HA05GER Well more stuff is more to break, thats true. However, at least if you do lots of miles in not too many years, it seems to be fine. I am involved in running a fleet of Taxis and I havent really seen any problems of note until they are sold on at 300k miles or so.
@@GoldenCroc do you use supermarket fuel ?
@@HA05GER We dont have any such distinction where I am at, we use whatever fuel we can get, and always did. Currently we use diesel fuel with 30% renewables mixed in, as is the law here. Earlier we have used fuel with as much as 100% renewables because of contract stipulations. No differences of note.
All in all, I seriously doubt there is much distinction between "supermarket fuel" and anything else chemically either if you are in western europe, as far as I know, these things are pretty regulated...
Dpf is crap technology in my opinion. My Honda CRV (2011) has one mounted on the front of the engine. It is intended to periodically ramp up to 700 deg C with extra fuel burn when the differential pressure reaches a certain value. Sadly this temperature is often not achieved even at motorway cruising speed in cold weather due to the airstream behind the radiator!
I have had the car default to limp home mode after a 200 motorway blast several times! After two expensive forced regens, I invested in an obd machine to do it myself. I used aerosols of dpf cleaner sprayed down the upstream pressure sensor duct into a warm dpf. Worked a treat every smoky time!
I wish I was clever enough to do the audit maths to establish if the continuous 3-5mpg extra fuel consumption was better or worse for the environment than the particulates that are only an issue in conurbations. Most of the clean technology carries a significant CO2 footprint price tag. Funny old world we enjoy since they invented “the science”!
These guys look a whole magnitude better in the job they do. 👍
Does seem daft having the DPF mounted in an airflow!
An extra 20 bhp?
A reclaimed 20bhp, perhaps!
I don’t like the look of those coffees at the end of the video! Yikes. Merry Xmas!

Wynns off car dpf cleaner would clean it
I doubt it would do it as thoroughly as this machine!
Sod that .. chop the dpf out and map it out ... not worth all the faff only for it to block up again
It lasted 164k miles...I can handle the faff 😆
Another solution is just to drill ot out 😂
I feel happier knowing I'm doing what I can for the planet tbh , even if it's not much. The DPF does work well, as previous MoT emissions tests have shown.
I spent over 10 years braking 1000s of Citroën and Peugeot cars that has let me see the worst and the way additive is guesstimated and complicated to deal with even if you know what you are doing has killed way to many cars
I can imagine. It all works, it's just counter intuitive to most people, so they don't get maintained/used right and end up failing anyway.
I filled the ad blue tank with Peugeot fluid. Has to be taken down and filled.

The best thing for the Eloy’s tank is to delete it Peugeot and Citroen have removed them completely now
@@bmwman1981 Really, I thought the blue hdi had the eloys and ad blue?
Peugeot used to use adblue and end Eloys in the first generation of 3008. The common problem with those was th3 tank had a habit of failing as mi e did 18 months old! I think these days they just use adblue and it is squirted into the system every time the engine starts. So, if you turn your stop/start off then you allow potentially the problem to build earlier.

No wonder why the C6 ran like crap!
It didn't, it drove surprisingly well. It was only the last trip out before we were due to go on hols that it threw the error message.
A 3 litre tank holds 200 15ml doses (3000/15). If 15ml is used per 100 litres of fuel that's 20,000 litres of fuel per eloys tankful ... Or 4,401 gallons (20,000/4.544, where 4.544 = 568ml per pint * 8 pint oer gallon).
At 30 mpg this would need the eloys tank filling at 132k miles!
(spot the deliberate mistake - this needs recalculating based on 2.3 litres if the refill warning comes on when 700ml is left ... That works out at a refill at about 100k miles)
Yeah, most cars seem to run out of pat fluid around 90-100k.
But can be a lot less if your a person that never fill their tank and puts just £20 a time in. It injects it into the fuel tank and it's a dumb system that doesn't know how much fuel you put in, it only know that you have open the fuel cap. So assumes you have filled it.
Which is roughly what people say you get from them.
This kind of stuff makes me stay away from diesel cars.
