Its car manufacturers who are at fault , what each car should have is soot level read out on the car media system . This would help people know when the car is in regeneration. Problem is people dont know .
Excellent comment, if we know when a good run is needed by the car telling us it needs to regenerate then there would be less hassle. I routinely run my car down the motorway every 3 weeks and give it a blast for a few miles.
The biggest problem is that it will NOT solve the real problem, it will be blocked up again in another few months. I had many diesels and found it was the way they were driven. I even broke a new diesel of my own and had the manufacturer replace the DPF after 9000 miles, then had to get another one after 14000 miles. I was going a mile or two to the shops in this particular car, going to work through 30mph town traffic and stop/start traffic (with stop/start engine system) and only covering 8 miles each way. I used to have to take the car down the motorway at 60mph for 30mins to clear it every few weeks or the DPF would start causing errors. The main dealer altered the car so it regenerated at every 300miles whether it needed it or not, this caused further problems with the servicing of the car. When a car regenerates, it pumps fuel in during the exhaust cycle and heats the cat and DPF, but this diesel also gets in to the oil. This causes excessive wear and tear and melts glowplugs too. The best advice is to remove the DPF completely, reporgram the car to remove or delete the DPF and bribe the MOT testing station to pass it. In the UK most garages will pass cars without a CAT and DPF by driving a car in next to yours and taking the readings off that one. It's well known and the only way to stop your car being destroyed. I now have petrol cars and get 20mpg less, cause far more CO2 and pay far more road tax - all to apparently clean the air!
@@Bond2025 Thank you for the comment regarding the fact that diesel gets into the oil. This is what I heard in a German video as well. This can destroy an engine. I generally like diesel cars but I would not buy one with a DPF. Although I really liked my Golf Mk5 GTD, I sold it years ago.

Carbon Cleaning, or HHO Cleaning, is very good for cleaning the combustion chamber, EGR, and Turbo, it works by pumping Hydrogen into the combustion chamber. I used to have a machine myself, and it does give impressive results for removing carbon build up in diesel and petrol engines. But it will not clean or even touch your DPF, as you rightly stated.
Too many seem to think they can get away with just resetting the sensor. Had a customer just yesterday after a carbon clean & a dpf clean, the guy came with a big machine in his van said they clean the dpf, he showed the customer that the value is 0 and left, 15 miles later the dpf came back, had to go out there as an emergency call out due to the poor chap going abroad the very next day.

Another great video. I had mine blocked up (Audi A4 3.0 TDi - 95kmls) & it went into limp mode. That meant that I couldnt rev it high enough to blast down the motorway for a dynamic regen. It was too blocked for the system to allow a static regen. Some people were telling me that it was too far gone & would need replacement. However, I used the code reader to trick the car into thinking I had replaced the DPF. By doing that, it meant that I could get it out of limp mode. I then went for a blast on the motorway btu that didnt seem to clear it enough. I could then however get the system into a static regen (with a fire extinguisher nearby because it had a bit too much soot & therefore a fire hazard. That worked a treat & got the differential pressure down to about zero. So my suggestion is that if you cant get it to do a static regen, then first tell it that you have a new DPF & then do a static regen.
was lucky with toyota verso as it only supports dynamic regen, dumped a bottle of DPF cleaner and managed to get it clear enough to trigger a regen been fine ever since my dad was only going to work and back, no long motorway trips so it wasn't doing any regens and not getting hot enough to regen witch is what blocked it by 0.80 i think witch i guess means 80% blocked got it down to 0.60 on the spot trying to do a static regen that it won't do (was a waste of time but did go down 20% just sitting at 3000 RPM standing still) after 2 days and some motorway driving and a bottle of DPF cleaner it was low number and the cars functions wasn't disabled anymore (like no turbo/limp mode/stability control program disabled/the gear change indicator disabled after 15 seconds)

When I worked for JLR we had loads of these to sort out. Plug computer in, run till normal working temperature is reached then drive the car at 25mph, or 40kmh, for about 12 miles. This will clear a DPF that is up to 97% full!

That’s why I delete the dpf off any diesel vehicle I own. Take it off cut the top hollow it out and wack it back on the car. Map it out, job done. Horrible invention.
I wish my Transit custom would give some indications it is doing a regen. Had it four years and no idea if its done them in the past. When I had it around 2 years I needed a new DPF sensor of something fitting. It's mad, the van flashes up is a lightbulb goes out or if the washer fluid is low, but zero indication of any thing regarding the DPF. It's like a waiting game expecting it to one day say the DPF is shagged, open your wallet for a new one.
Thank you for the videos and sharing your knowledge..A question; what is that pipe called that you disconnect to put wynns cleaner in. Is it the same on all cars? Thinking of doing mine (1.7cdti zafira B in Spain!!!). Thanks again.. Some local guy here wanted 550 €s to clean DPF!!!!
I've seen many issues with people resetting Ash mass values to 0 and assuming this cures dpf faults,and people thinking a dpf clean is going going to fix a dpf that has reached its ash limit.
Great info there lad, I run a hydrogen machine at the garage with great succès but it's not used by me or portrayed as a dpf cleaner as you've shown here. 👍Keep up the great work. 😎
That's why I've spent years learning to fix the car myself using workshop manuals and sticking to torque values on rebuild. Don't trust anyone to either do it properly or for a fair price without fictitious parts replacement too.
Had a dpf issue with my wifes car. I put all the chemistry in the world through it via the dpf sensor and it worked after a rest for 100miles. Its a pain but you have to take the dpf off and jetwash, soak, jetwash and get a forced regen and your good to go. Anything less is meerly a band aid plaster. If you don't do the miles get a petrol is the only advice I'd give. If you habe the tools and knowledge (which can be gained) you can clean it yourself and says a load of money.
@@ORileysAutos That doesent work on my 2011 Kangoo either. And when I try a forced regeneration it fails aswell, saying "The relative pressure inside the PDF is to low"
My son's traffic on a 16 plate the garage charged £800 to drill a hole in it and remap the ecu.....I have watched all your stuff. I feel the filter will still clog up ekk what happens then I know he has been ripped off with future problems and this was a proper garage ish.....
Good video and great info, would a static DPF regen through your scanner not work ? I have done a few on the mrs Volvo as she only does short journeys, it always clears it. Have never thought to look at the live data before and after, so will use the info you have provided to do that if mine does it.
great detailed video.I have a 2010 Volkswagen Phaeton which I have had parked up ,just running to put charge in battery. Went to give it a good run as the dpf light was on but now glow plug flashing and stuck in limp mode.Could this be the exhaust pressure sensor, as members club said or a clean. 3.0 tdi.
thanks for your videos. It often happens to me on Euro 6 cars to find in the diagnosis the particulate filter parameter of the exhaust gas flow resistance. The value is expressed in hpa/m3h. Do you know the optimal values when a dpf is clean?
Welcome to modern motoring and the plight of EGR. Older cars are actually better but obviously not everyone can drive them in there city anymore. Petrol is far better.
Have ye all gone bonkers in the dirty auld town, don't buy cars that have to be driven far enough to bring the engine temp to max on a regular basis to get rid of condensation from the engine, ye are throwing good money after bad . Solution open Bonet, find engine oil cap and remove,, look in hole😮 if you see slimy scum 😢 put Cap back, close Bonet and bring the beast for a long drive and ask yourself would any of my neighbors really care if I were dead tomorrow and do you really have to show up at the school down the road or family event for that matter in a diesel range Rover. The people who drive this type of vehicle live on working farms and use them to pull horse boxes around the country holding up the real tax payers in this country the paye workers trying to get home before there kids are gone to bed. Bit of sound advice trade for petrol it's engine runs hotter.
Thanks. Kind, Sir. From the owner of. B18 JHP. Payed. 180. Quid. The other day. For a, DPF. Clean. I went to a, Garage. Belle Isle, Road.Leeds. Halfords, is my chosen garage. Paying, 17. Monthly. Free mot, and service. Halfords Motoring Club. Honesty, is the best policy. Thanks, again.
How does this method compare to actually taking the dpf off the exhaust and using the off car cleaner. I have a Sprinter van that keeps going into limp mode, having long crank issues and stalling.
jetwash if that's what you mean you can damage the DPF (this person is using actual DPF cleaner foam) i would try dpf cleaner that can be put in the fuel tank and do some motorway driving (but you could do with getting someone to plug a computer in to see what the problem is)
I had a failed DPF valve failure on my VW Caddy. All I did was to re-map it. Also occasionally driving it like you stole it is good for all diesel engines.
Or may be better to meet the requirements of a correct regeneration. I've driven some larger trucks that if you let off the Excelerator or touch the brakes the regeneration is canceled. On cars there is a criteria that it needs to meet before the regeneration starts
So it looks like that big machine is just a hydrogen oxygen generator. It just uses electricity to produce hydrogen and oxygen by splitting water, and the only thing it is supposed to do is raise the temperature of the combustion chamber to the point that the carbon starts to burn off. Seems rather pointless to me. They say you put it in the intake and it cleans the intake manifold the EGR the combustion chamber the turbo and the DPF. Not really much of a chance that will work properly on soot. It's basically a forced region that just cooks the carbon on permanently. Does not appear to work on intake valves at all. It's really only designed to clean combustion chamber and who knows if it does that very well. I posted a video further on down that shows there's almost no difference after hydrogen cleaning. Intake valves just as dirty, and no change on Dyno horsepower output.
the only cleaning you can test with out a lot of work to pre check and post check test is on the DPF with dif presure drop. this type of cleaning will just be like a re-gen with high temp burn off. I know you try to avoid re-gens due to damage so maybe you should watch the DPF temps as you do the cleaning.
How can it clean the EGR and the intake manifold as they are both positioned before (inlet flow) you reach any alleged raised temperature of the cylinder block? The turbo and the DPF seems plausible as they’re both positioned after the the cylinder block (exit flow) and could benefit from carbon burning higher temperature exhaust gases. Also, a lot of vehicles have plastic intake manifolds so even if the temperature was raised high enough to burn carbon it would melt the intake manifold into the bargain.
@@JustMe-Dude If your car is failing to automatically re-gen you can perform a forced DPF re-regeneration through the OBD2 port with the correct software for your car, which is easily downloaded, a laptop and a USB/ELM cable. No damage is done during the regeneration process and you can read all the before and after parameter results. I personally use MultiECUscan as it’s the correct software for my cars.
@@One_over_the_eight I use a Launch PAD V, but I prefer to avoid force regeneration if possible. Cleaning is a much more thorough and less chance of damage method. Regeneration can cause damage sometimes and I've even seen where a partially blocked DPF with a forced regeneration caused a chunk of carbon to block the DPF as it baked on harder instead of burning off.
I run a Hydrogen Clean company and my machine does work so until you have used one that works don’t assume they don’t but as I tell my customers it won’t clean the DPF two totally different systems but you should know that?
Of course I know that its different but lots of people are advertising it does intake, egr, Turbo, dpf. I've been offered a free carbon machine from a few top brands but wanted me to use it on videos.
well it does not do much: th-cam.com/video/Ro8IFUYryPg/w-d-xo.html granted the video is a little hard to get through and long, just skip through so you can see before and after results of a hydrogen cleaning system. For intake valves it's virtually nothing, claim of increased power is extremely marginal on the Dyno.
Problem is anyone can just buy a carbon cleaner and call themselves UK DPF cleaner etc. I know a guy who was doing recovery truck driving used to get me to do his brake pads but next thing he sells his recovery truck and he's doing DPF and carbon cleaner specialist lol
@@neildean7515 no they don’t really work. The best way to sort the DPF is prevent it getting blocked up in the first place. Drive the car more than 20 miles every week or more then you won’t have any issues. Drive to the shops all the time and back then you’ll get issues
The other option is to get the dpf Modified : I can tell you from personal experience you can have a regen they call it have it took off and cleaned in a special factory cost £ 250 and a few weeks later it could go again , however there are garages specialist in un welding it taking all the insides out and re welded so it’s like new ,then having the engine remapped so that it doesn’t know you’ve got one that’s the permanent solution ,it passed two mots no problem , and will never go wrong again costs 350 worth every penny
Im lucky enough to have a large ultrasonic bath,carbon cleaner and rinse followed by a mild solution of brick descaler until all the red ash is out,rinse rinse rinse,reset the dpf,job done.
Way to much work on a car or small truck. Need to reserve that one for the big trucks. Quick and simple on the car cleaning is definitely the way to go
@@JustMe-Dude we took ours twice to a garage only to have the fault come back the next day, removing the soot wasn't enough, so I removed it and cleaned it myself now it's like new again. Luckily this was on a Peugeot partner so it was only 5 mins to take off
How do I find someone local that would know what they are really doing. My warning light still comes on a few days after a regen, been like this for over a year now....I'm in Derbyshire, any recommends folks?
hello mate, I have had my engine management light come on, after a diagnoses i was advised that the DPF filter is not regenerating. had a forced regeneration done however few days later the light came back on. What do i need to do, the car is only 4 years old and has done 50k miles?
would it be possible to use the launch uk fluid without having to buy the gun and a compressor. say like putting it in a plastic bottle and squeezing it in. i do my own work on my car but don't really want to fork out the expense of buying those items when i'll probably only need to clean the dpf once or twice
I have a fleet of bt50s i look after that idle a lot and are always getting soot accumulation codes. After watching your vehicles I think I will get a scanner that will work on these and the dpf cleaning kit. I am in Australia, how much do you think i should charge?
hi! i've got LRDS 2020 with 2L diesel ingenium. what diagnostic device would you recommend to buy so i could monitor dpf pressure and soot mass and get the car to workshop before it's too late since my local dealer would be happy to replace everything and invoice me rather than inspect and clean the system? euro-tab-III is a bit too pricey for a non-professional.
Mr O Reilly you need to take more care of your health. Modern vehicles are known to use fluids which can be carcinogenic. You should be wearing gloves, maybe even safety glasses and a mask? Apart from that you are doing a great job.
Hi mate, I don't have any issues with my DPF but I've got a high mileage diesel (170k) - are the launch additives worth a look? My car doesn't get the miles it should, so wondering if they'd be any good for it?
Just give it a good drive up the motor way for maybe 40 miles or more a couple of times a month. If you can’t then sell the diesel and get a petrol. No need to do these cleans if you drive the thing at least 20 miles on a trip.
15-30 minutes driving in 4th or 5th gear minimum of 50mph and your DPF will be 95% clean just from that and do this once a month. Chuck in some Redex fuel additive every 3-6 months before one of these journeys and you'll never need a professional DPF clean. If you own a diesel you should be doing 30 minute journeys on the motorway at least a few times a week really, if you're not then you should save on the hassle and get a petrol car. The fuel economy that comes with diesel only really makes a huge difference on the longer journeys, otherwise you're paying more in DPF costs for the short journeys
Watched a video recently where the tech plugs the diagnostic in ti the car , and takes it out in a long run , he then runs a re gen programme where you see the doot level drop to zero , and then he stops and sets the diagnostic up to deal with the ash content runs the car untill zero ash content ....is this a genuine process .....your thoughts please ....and thanks ...
Hi mate. I got the same problem with my bmw 520d . I’m based in Birmingham. How much do you charge for your service? And do you know anyone in bham that can do as good job as you?
as Jimmy has said many times, a malfunction somewhere in the system can cause regenerations to no longer happen, and the DPF to plug up from lack of normal regeneration.
Does my 2012 W212 Mercedes CDI show DPF condition on computer? I drive too gently and only do highway once or twice per month. I'm curious about its condition. On my highway drives I slow to 90 and punch it to 180 twice a few miles before my exit, normaly after two hours of 120-130kph.
Had my corsa dpf cleaned, and as you said drove it half dozen times, and was clogged up again. Was told its because the injectors need changing 🤷🏻♂️ Swapped dpf for a new one, car has been fine for months
Carbon cleaning does work only on the engine won't work on the DPF even the manufacturers will tell you it won't work on DPF may increase the temperature In the DPF very slightly but most of the people doing this haven't got a clue what they are doing you only have to think about it logically to know it not going to work on a DPF I've looked at car afterwards and they have made the Car worse
DPF delete FTW. Useless piece of kit really. Read a few papers on the health hazards associated with working around them, it’s a class action law suit waiting to happen.

Poured it down with no compressor? Don't know how DPF Fixer is still in business
Great video, very informative! Any idea of cost to do a 2019 Navara? Also what cleaner do you use?
Thanks
That’s why I delete the dpf off any diesel vehicle I own. Take it off cut the top hollow it out and wack it back on the car. Map it out, job done. Horrible invention.
I wish my Transit custom would give some indications it is doing a regen. Had it four years and no idea if its done them in the past. When I had it around 2 years I needed a new DPF sensor of something fitting. It's mad, the van flashes up is a lightbulb goes out or if the washer fluid is low, but zero indication of any thing regarding the DPF. It's like a waiting game expecting it to one day say the DPF is shagged, open your wallet for a new one.
You can buy a indicator light that co.es in when dpf regen attempts
@@ORileysAutos Oh, I never heard of that. is it a quick and easy and CHEAP mod?
Thank you for the videos and sharing your knowledge..A question; what is that pipe called that you disconnect to put wynns cleaner in. Is it the same on all cars? Thinking of doing mine (1.7cdti zafira B in Spain!!!). Thanks again.. Some local guy here wanted 550 €s to clean DPF!!!!
Dpf differential pressure sensor hose
I've seen many issues with people resetting Ash mass values to 0 and assuming this cures dpf faults,and people thinking a dpf clean is going going to fix a dpf that has reached its ash limit.
It can cause it to overheat and damage it
Great info there lad, I run a hydrogen machine at the garage with great succès but it's not used by me or portrayed as a dpf cleaner as you've shown here. 👍Keep up the great work. 😎
Thanks
Great job man as always. Id nearly get the boat so you could look at mine.😂
There's nothing better than breathing in and out.... all the rest is a bonus. Good vid.
Thanks
You do a great job, but you should use disposable protective seat covers in customers cars about £3 for a pack of ten
If you are not dirty no harm.done
💯 took my car to a garage when I was younger and the guy got in it with oily overalls and got an oil patch on my new Corbeau seat 💺 🤬🤬🤬
The biggest question that comes to my mind out of all these videos, which are great by the way, is who the hell do you trust??
That's why I've spent years learning to fix the car myself using workshop manuals and sticking to torque values on rebuild. Don't trust anyone to either do it properly or for a fair price without fictitious parts replacement too.
Try selecting an older model year manually and it will.give you the options to reset
Had a dpf issue with my wifes car. I put all the chemistry in the world through it via the dpf sensor and it worked after a rest for 100miles. Its a pain but you have to take the dpf off and jetwash, soak, jetwash and get a forced regen and your good to go. Anything less is meerly a band aid plaster. If you don't do the miles get a petrol is the only advice I'd give. If you habe the tools and knowledge (which can be gained) you can clean it yourself and says a load of money.
Do not Jetwash your DPF. Serious damage will occur
2500 rpm on motorway for 20 minutes and it will have unblocked, works a treat. Don’t need to pay any money to anyone
That wouldn't work on these
@@ORileysAutos That doesent work on my 2011 Kangoo either. And when I try a forced regeneration it fails aswell, saying "The relative pressure inside the PDF is to low"
Cool, but the question is, how do we know what a reputable firm is? Is there any sort of membership body etc that reputable firms are part of?
I wish you covered my area - would hire you in a second to sort my DPF out
My son's traffic on a 16 plate the garage charged £800 to drill a hole in it and remap the ecu.....I have watched all your stuff.
I feel the filter will still clog up ekk what happens then
I know he has been ripped off with future problems and this was a proper garage ish.....
thank you for being honest these days a lot are out to make a quick buck .thanks for the video
Good video and great info, would a static DPF regen through your scanner not work ? I have done a few on the mrs Volvo as she only does short journeys, it always clears it. Have never thought to look at the live data before and after, so will use the info you have provided to do that if mine does it.
@frankobrien9124I had a autel mk808 at the time. great little unit for DIY mechanic
great detailed video.I have a 2010 Volkswagen Phaeton which I have had parked up ,just running to put charge in battery. Went to give it a good run as the dpf light was on but now glow plug flashing and stuck in limp mode.Could this be the exhaust pressure sensor, as members club said or a clean. 3.0 tdi.
Could be lots of things. It would need scanning
@@ORileysAutos ok thank's
Sounds like a typical DPF Fixer scam
😬
thanks for your videos. It often happens to me on Euro 6 cars to find in the diagnosis the particulate filter parameter of the exhaust gas flow resistance. The value is expressed in hpa/m3h. Do you know the optimal values when a dpf is clean?
A good dpf is around 5mbar at idle & 50mbar at 3k revs
You just wouldn't think you'd need expensive maintenance like this on a modern vehicle with 4,000 miles on the clock!
Its done 44k miles
City driving any diesels will do it
Welcome to modern motoring and the plight of EGR.
Older cars are actually better but obviously not everyone can drive them in there city anymore.
Petrol is far better.
Have ye all gone bonkers in the dirty auld town, don't buy cars that have to be driven far enough to bring the engine temp to max on a regular basis to get rid of condensation from the engine, ye are throwing good money after bad . Solution open Bonet, find engine oil cap and remove,, look in hole😮 if you see slimy scum 😢 put Cap back, close Bonet and bring the beast for a long drive and ask yourself would any of my neighbors really care if I were dead tomorrow and do you really have to show up at the school down the road or family event for that matter in a diesel range Rover. The people who drive this type of vehicle live on working farms and use them to pull horse boxes around the country holding up the real tax payers in this country the paye workers trying to get home before there kids are gone to bed. Bit of sound advice trade for petrol it's engine runs hotter.

Great video mate. Do you do this for Skoda Rapids 1.6tdi's at all?
Yes
Makes it so simple Dont he.
Hes a very nice man.😅
Glad this popped up,want to get mine done soon so good info
I would get it done except my 98 s70 tdi doesn't have one 🎉
How does this method compare to actually taking the dpf off the exhaust and using the off car cleaner. I have a Sprinter van that keeps going into limp mode, having long crank issues and stalling.
jetwash if that's what you mean you can damage the DPF (this person is using actual DPF cleaner foam)
i would try dpf cleaner that can be put in the fuel tank and do some motorway driving (but you could do with getting someone to plug a computer in to see what the problem is)
Fantastic video, you are a rare breed of mechanic. What is the set up and liquid you used to clean with? I would like to try it myself.
Available at Launchtech.co.uk
I had a failed DPF valve failure on my VW Caddy. All I did was to re-map it. Also occasionally driving it like you stole it is good for all diesel engines.
Or may be better to meet the requirements of a correct regeneration. I've driven some larger trucks that if you let off the Excelerator or touch the brakes the regeneration is canceled. On cars there is a criteria that it needs to meet before the regeneration starts
So it looks like that big machine is just a hydrogen oxygen generator. It just uses electricity to produce hydrogen and oxygen by splitting water, and the only thing it is supposed to do is raise the temperature of the combustion chamber to the point that the carbon starts to burn off. Seems rather pointless to me. They say you put it in the intake and it cleans the intake manifold the EGR the combustion chamber the turbo and the DPF. Not really much of a chance that will work properly on soot. It's basically a forced region that just cooks the carbon on permanently. Does not appear to work on intake valves at all. It's really only designed to clean combustion chamber and who knows if it does that very well. I posted a video further on down that shows there's almost no difference after hydrogen cleaning. Intake valves just as dirty, and no change on Dyno horsepower output.
I'm going to get one and make some videos on results
the only cleaning you can test with out a lot of work to pre check and post check test is on the DPF with dif presure drop.
this type of cleaning will just be like a re-gen with high temp burn off. I know you try to avoid re-gens due to damage so maybe you should watch the DPF temps as you do the cleaning.
How can it clean the EGR and the intake manifold as they are both positioned before (inlet flow) you reach any alleged raised temperature of the cylinder block? The turbo and the DPF seems plausible as they’re both positioned after the the cylinder block (exit flow) and could benefit from carbon burning higher temperature exhaust gases. Also, a lot of vehicles have plastic intake manifolds so even if the temperature was raised high enough to burn carbon it would melt the intake manifold into the bargain.
@@JustMe-Dude If your car is failing to automatically re-gen you can perform a forced DPF re-regeneration through the OBD2 port with the correct software for your car, which is easily downloaded, a laptop and a USB/ELM cable. No damage is done during the regeneration process and you can read all the before and after parameter results. I personally use MultiECUscan as it’s the correct software for my cars.
@@One_over_the_eight I use a Launch PAD V, but I prefer to avoid force regeneration if possible. Cleaning is a much more thorough and less chance of damage method. Regeneration can cause damage sometimes and I've even seen where a partially blocked DPF with a forced regeneration caused a chunk of carbon to block the DPF as it baked on harder instead of burning off.
Sunny Suffolk needs a winner tonite badgers
I run a Hydrogen Clean company and my machine does work so until you have used one that works don’t assume they don’t but as I tell my customers it won’t clean the DPF two totally different systems but you should know that?
Of course I know that its different but lots of people are advertising it does intake, egr, Turbo, dpf.
I've been offered a free carbon machine from a few top brands but wanted me to use it on videos.
well it does not do much: th-cam.com/video/Ro8IFUYryPg/w-d-xo.html
granted the video is a little hard to get through and long, just skip through so you can see before and after results of a hydrogen cleaning system. For intake valves it's virtually nothing, claim of increased power is extremely marginal on the Dyno.
What nodel of Milwaukee air compressor?
Problem is anyone can just buy a carbon cleaner and call themselves UK DPF cleaner etc.
I know a guy who was doing recovery truck driving used to get me to do his brake pads but next thing he sells his recovery truck and he's doing DPF and carbon cleaner specialist lol
Whats you thoughts on injector/DPF cleaner liquids that you can pour into fuel tank… (ie Liquid Moli 2509). Do they work ?
@@neildean7515 no they don’t really work. The best way to sort the DPF is prevent it getting blocked up in the first place. Drive the car more than 20 miles every week or more then you won’t have any issues. Drive to the shops all the time and back then you’ll get issues
The other option is to get the dpf Modified : I can tell you from personal experience you can have a regen they call it have it took off and cleaned in a special factory cost £ 250 and a few weeks later it could go again , however there are garages specialist in un welding it taking all the insides out and re welded so it’s like new ,then having the engine remapped so that it doesn’t know you’ve got one that’s the permanent solution ,it passed two mots no problem , and will never go wrong again costs 350 worth every penny
Do you get sick of working out in the open ie rain slash no room....you need a garage with lifts.
Im lucky enough to have a large ultrasonic bath,carbon cleaner and rinse followed by a mild solution of brick descaler until all the red ash is out,rinse rinse rinse,reset the dpf,job done.
Way to much work on a car or small truck. Need to reserve that one for the big trucks. Quick and simple on the car cleaning is definitely the way to go
@@JustMe-Dude we took ours twice to a garage only to have the fault come back the next day, removing the soot wasn't enough, so I removed it and cleaned it myself now it's like new again. Luckily this was on a Peugeot partner so it was only 5 mins to take off
How do I find someone local that would know what they are really doing. My warning light still comes on a few days after a regen, been like this for over a year now....I'm in Derbyshire, any recommends folks?
I don't know anyone in Derbyshire.
I know someone in North Wales & Luton
Please can you give me the contacts for Luton?
Is there a reason you manually hold the revs and don't carry out a forced reg?
No need to regen if using flush fluid. Much safer method no using forced regenerations
hello mate, I have had my engine management light come on, after a diagnoses i was advised that the DPF filter is not regenerating. had a forced regeneration done however few days later the light came back on. What do i need to do, the car is only 4 years old and has done 50k miles?
do you replace rusty brake pipes to?
Not happily 😅
would it be possible to use the launch uk fluid without having to buy the gun and a compressor. say like putting it in a plastic bottle and squeezing it in. i do my own work on my car but don't really want to fork out the expense of buying those items when i'll probably only need to clean the dpf once or twice
Would it be OK Not to zero the figures and just replace the dpf sensor (faulty) I don't think my CRP 129 evo is able to reset the DPF settings ?
I have a fleet of bt50s i look after that idle a lot and are always getting soot accumulation codes. After watching your vehicles I think I will get a scanner that will work on these and the dpf cleaning kit. I am in Australia, how much do you think i should charge?
also what type of scanner would you suggest
how often should dpf cleaned
hi! i've got LRDS 2020 with 2L diesel ingenium. what diagnostic device would you recommend to buy so i could monitor dpf pressure and soot mass and get the car to workshop before it's too late since my local dealer would be happy to replace everything and invoice me rather than inspect and clean the system? euro-tab-III is a bit too pricey for a non-professional.
Mr O Reilly you need to take more care of your health. Modern vehicles are known to use fluids which can be carcinogenic. You should be wearing gloves, maybe even safety glasses and a mask? Apart from that you are doing a great job.
I'll try 🙏
Hi mate, I don't have any issues with my DPF but I've got a high mileage diesel (170k) - are the launch additives worth a look? My car doesn't get the miles it should, so wondering if they'd be any good for it?
Launch flow restorer helps short journeys as it helps clear soot at much lower temperatures where longer journeys aren't done.
@@ORileysAutos Nice one, cheers! Great channel by the way - didn't realise how complex DPFs were really
Just give it a good drive up the motor way for maybe 40 miles or more a couple of times a month. If you can’t then sell the diesel and get a petrol. No need to do these cleans if you drive the thing at least 20 miles on a trip.
I also found by cleaning a nearly blocked EGR valve helped increase milage on my 1.7cdti by 25%…
15-30 minutes driving in 4th or 5th gear minimum of 50mph and your DPF will be 95% clean just from that and do this once a month. Chuck in some Redex fuel additive every 3-6 months before one of these journeys and you'll never need a professional DPF clean. If you own a diesel you should be doing 30 minute journeys on the motorway at least a few times a week really, if you're not then you should save on the hassle and get a petrol car. The fuel economy that comes with diesel only really makes a huge difference on the longer journeys, otherwise you're paying more in DPF costs for the short journeys
DPF cleaner in st Alban's has no idea what he's doing
There is one who does kent and essex who doesn't too.
@sensible driver that's what I'm here for. Hopefully they can watch and improve there workmanship
Watched a video recently where the tech plugs the diagnostic in ti the car , and takes it out in a long run , he then runs a re gen programme where you see the doot level drop to zero , and then he stops and sets the diagnostic up to deal with the ash content runs the car untill zero ash content ....is this a genuine process .....your thoughts please ....and thanks ...
It is a pity you don't work in lrland.
Wonderful job 👏
Thank you! Cheers!
Just tested the pressure on my Honda CRV and it's reading around 10 kpa at idle. Would you say its blocked ? 👍
Yes. Definitely
@ORileysAutos that's what I thought, cheers 👍
if motors with 60+ k miles suffer from constant dpf cloging there is a chance that some of the injectors are not performing as they should
Where are you located mate?
Hi mate. I got the same problem with my bmw 520d . I’m based in Birmingham. How much do you charge for your service? And do you know anyone in bham that can do as good job as you?

Thats amazing job
So the cause of the dpf blocking was the adblue injector being blocked stopping the regen process? Just sub'd btw.
as Jimmy has said many times, a malfunction somewhere in the system can cause regenerations to no longer happen, and the DPF to plug up from lack of normal regeneration.
@@JustMe-Dude But on this occasion it was a blocked adblue injector.
The problem with new technology is it's not tried and not tested.
How big is tree foot high and tree foot wide?.
How long is a piece of string?
@@ORileysAutos About tree foot two ;). Good crack :)

Well done!
Does my 2012 W212 Mercedes CDI show DPF condition on computer? I drive too gently and only do highway once or twice per month. I'm curious about its condition. On my highway drives I slow to 90 and punch it to 180 twice a few miles before my exit, normaly after two hours of 120-130kph.
Slowing and punching it is probably causing the regeneration to stop because conditions are no longer met.
Hi. What area are you covering roughly with your services?
Bedfordshire
@@ORileysAutos Nice. Not too far from me and my close friend lives in Bedford. Thanks.
This is all well-and-good Mr O'Riley but the thing is, in England you can't find a mechanic who'll tackle DPF issues, let alone an honest one!
Mr O'Riley is in England.....try him
Had my corsa dpf cleaned, and as you said drove it half dozen times, and was clogged up again.
Was told its because the injectors need changing 🤷🏻♂️
Swapped dpf for a new one, car has been fine for months
Carbon cleaning does work only on the engine won't work on the DPF even the manufacturers will tell you it won't work on DPF may increase the temperature In the DPF very slightly but most of the people doing this haven't got a clue what they are doing you only have to think about it logically to know it not going to work on a DPF I've looked at car afterwards and they have made the Car worse
