- Cleaning the dpf soot on high mileage vehicles is not always successful due to ash solids that can build up.
here I attempt to clean the ash in situ using an acid based chemical

So the "soot" value is a calculated value by the ECU ? I guess the only worrying thing here is that you could potentially be mis-led if there were a number of other issues leading to failed regens ? I can see where this will lead .......... future parts cannons. Great that you actually tried to clean it first Jimmy rather than just throw a DPF in it straight away. Bravo yet again. Top Man.
It would be very difficult for the vehicle to actually measure how much soot is in the DPF. The calculated value is determined from lots of experimentation and testing and a very clever model that uses lots of data including the differential pressure.
Never tried the brick acid but I had the issue on my old Berlingo 1.6 hdi and as a heating engineer I used a bottle of fernox f3 central heating cleaner and it got all foamy out the tail and cleaned it out never had the fault again 🤷♂️ vans still on the road 3years later by another lad
Because of your previous video with the acetic acid I tried cleaning my Trafic (Talento to be honest) with brick cleaner and water, although diluted more than you did.
Had the van running while injecting it into the DPF, shut the engine off immediately after and had it soaking for 15 minutes. Ran it for a while to get everything out of the exhaust and now I have a far more responsive van and a higher mpg.
The live data figures aren't as low as you show there, though.
Thank you for all your helping and informative videos!
Another school day from Master Jimmy 🙏. Keep it up mate👍🏻
you're a top bloke Jimmy, easy the way you explain stuff👍 I'm following your videos with great intrest ,thanks and keep up the great work helping people 👍👍
Great job . I use G101 from autosmart down pressure pipe. Works a treat. Youre right about dpf pressure. These vans a very moody. Any excess differential pressure or any implausible readings. That anti pollution light is coming straight on
Watched virtually the entire channel, back to the plant sprayer days 😂 Got tucked up with a Renault Master 19 plate, CHECK EMISSIONS after 6,000 miles. Used spray can cleaners. No effect. Used 2 part cleaners with plant sprayer to limited effect. Used acetic acid 40% 24hr soak, got pressure down to 7hpa. Was happy with 1.75% oil dilution in a 1200 miles. Thought a longer soak will be awesome. Left 1 litre in over Easter. Totally f*cked it. Every time I cleaned it, it got worse. Idling 12-14 hpa. Bought the Launch fluid. No effect. Got to the point of oil changes required almost every week, 8-9% oil dilution. Regen? Soot content was rising ffs. Fitted new a DPF last weekend, idles 6-7hpa when hot, 3hpa on start up, 1% oil dilution after 1200 miles..£750 free delivery, £80 fitting.
Too strong of a solution for too long of a period of time and corroded all of the flashed metal out of the system so it could no longer passively or actively regenerate. Looks like a stronger solution for a longer period of time just eats all of the good stuff off of everything as well as the ash and you end up with a straight pipe.
@@JustMe-Dudestraight through pipe, solve all the problems, we don't need all this shit they're putting on cars and vans these days !! 🤬🤬🤬🤬
@@Mr4fksake except straight pipe plugs up SCR with soot right away. would still need everything removed and a remap so it doesn't go into limp mode but won't pass MOT. agreed all of this after treatment sucks but sometimes you just have to live with it and move on.
Leading the way again Jimmy, what a result. Will be interesting when you use this method again. Maybe launch could incorporate an acid type solution in with the already amazing fluid, something to think about ??
Keep up the amazing work 👏 👌
Who would of thought Brick Acid would be a thing, folk will try anything & that’s how we learn these tricks 👍
Jimmy? you switched to a differnt acid.
First time around Jimmy tried brick cleaner it was ACETIC ACID, and appears to be a high grade of pure synthesized vinegar. Regular vinegar (3% to 6%) of course won't work you would need at least higher percentage concentrate, so brick cleaning acid (20%) is a good choice. You could actually buy cleaning vinegar at 35%, 45% up to 75%. Probably worth a try but I would think running a DPF rinse after that higher concentration would be a good idea to stop corrosion of the metal coated parts, and the seams of the housing because the stuff eats steel pretty quickly. Pretty sure the preheat catalyst is Flashed platinum ( I just looked it up and platinum resists corrosion from Acetic acid 30%, and Acetic acid Glacial. best to put it in the pressure sensor line to avoid going through the cat, but this acid does eat rubber and neoprene pretty quickly so be careful with anything similar to rubber parts. No idea what it does to the metals in the SCR, but this is a last resort instead of paying $1500 or more for a new DPF. Definitely worth a try. The chemistry suggests that the micro particles of ash, which is actually metal deposits, would be corroded and dissolved. Nice way to get rid of ash Jimmy. Thanks for doing the research.
I have a mk6 ford transit 133k on clock don't think dpf has ever been done but now I lose power going up hills I been watching your video's and going to try some of your ways as dpf cleaning company told me over phone as its so high mileage I need to buy a fuel vaporizer from ford befor they even look at it so going to c if I can bring the old one back alive all from watching u and your tips thank u
Nice one Jimmy another one down the road
Jimmy would have been interesting….what came out of the exhaust pipe…… very interesting and informative…. Nice job 👍
Jimmy tfr is good for ash solids and I do oil change oil dilution brings codes back up nice video keep up the good work
Great work Jimmy
Great vid. Very helpful, going to look at doing this soon. Why don't people go through the oxygen sensor after the turbo? It's surely safer as it goes straight down to the catalyst and DPF, rather than being close to the cylinders?
Top man, very interesting, I've been using the launch fluid every since I discovered it on your channel, I have no need to try anything else as the launch fluid has worked every time, without fail.
I will definitely consider using the brick acid if needed.
Thank you for all the information, it's much appreciated. 👍
Thanks for video.
My daily constantly flashing up particle filter clean light. Thanks I’ll try the cleaning fluid.
It's called oxalic acid. I've used it several times in the past to rejuvenate dead DPFs, however it takes a long time sitting in a fairly strong solution to really work. You also need to almost constantly flush it back and forth to agitate it so works it's way in better. One word of warning, some DPFs contain materials that can be damaged by this acid, but most seem to be fine.
not oxyalic acid, read the ingredients on the bottle. ACETIC ACID 20%. not for soot, but for ash
@@JustMe-Dude it says 15% hydrochloric acid on the bottle, check the gray field, first line.
@@johantorngren6349 go back and look at his original video and you'll see it on the jug. he even makes the statement of what kind of acid is being used in his first experiment with brick cleaner video.
@@johantorngren6349 looks like Jimmy switched to a dreffent brick cleaner?!?
in his first video he used ACETIC ACID 20%. now hydrochloric acid 15%.
I guess Jimmy should tell us what works better...
Nice to see your "Cash is King" notice, for preferred payment :)
Good job, Jimmy! Anything to prevent parts unnecessarily going to the landfill.
Brilliant, any warnings for people trying this themselves 👍
Really good and informative videos 👍
My Mercedes OM605 Blue Tec engine have 0.04 gr soot conten dpf, but fill level is stuck at 400%.
I'll try foam DPF clean to see about soot content reduces.
Maybe I'll dismantle the DPF from the car and try to clean it.
Probably wasting your time and just need a scan tool to reset the maximum level that is stuck in permanent code.
As Jimmy has shown in the past sometimes that's all it takes is a good reset of all the memories that are locked in
R9m engine it might be that the engine is burning oil you have to use rn17 engine oil in them low ash many people do not and it causes the engine to burn oil and then clogs the dpf sympton not the cause .the engine has steel pistons in them to improve torque it wears the rings out usually they start having starting problems
Good work 👍
🔥🔥🔥 yes then Jimmy 👍👍👍
Have you managed to unblock DPFs that are blocked in excess of 70% whilst still on the car ?
I ask because mine is blocked but Wynns for example recommend removing the filter if blocked above 70%.
I have a transit custom with 25 kpa of pressure on idle, thinking now about puttin 7% HCL acid in it and soak for 30 mins, question is will i have to flush it afterwords?
Thank you for the awesome videos.
I have a 2017 master x62 with 62klm and running beautifully. Jimmy just wondering when I should have the dpf checked? Also if you could advise when to change the gearbox oil and coolant. Never been changed yet since new. Auto/manual type. Many thanks Jimmy. Jimmy from cork
Thank you very much for the information. I follow all your videos with great interest. RESPECT
Could you please tell me where you inserted the acid?
Dpf pressure sensor hose
Thank you very much for your reply and what amount of acid did you put in?
Nice job 👍
Great video. I have a mk6 gtd and getting alot of back pressure and struggling to boost but does at about 3k. Do you need to force a regen if using the dpf cleaner or just monitor live data?
When was the last time you had to fix your own vw crafter ? Just curious 😃😃
Is it true if you un plug the air mass flow sensor when injecting fluid in to a dpf that sits high in the engine there is les chance of it flowing back because it closes the egr valve ? Would like to know a wee bit more about dpfs that sit high 😉😉 another great video mate
Bit late to party here but did you find out if egr stays closed when disconnected
@@MichaelBrookfield-m8n They say that on the video for the JLM DPF gun 🤔🤔🤔
Did you find a new location outside toolstation now hahaha
Love it.
We had a Vito with the Renault engine at work, said to drive at high rpm, dpf warning.
Garage done a forged regeneration and message gone.
Personally i'm not a fan of a forced regen.
Cheers jimmy, Distilled Water with Battery Acid about 50/50, that should shift the stubborn ones.
Yes and eat all the metal off of everything including the seams at the welds. Would have a non-functioning CAT, DPF, and SCR with a tail pipe full of holes. Great idea........
Jimmy would help me with my vivaro van 2016. The engine cranking but no firing I checked the electrical unit all working properly. I wonder what is wrong with.it. Thanks
I liked this video.
Now get that oil changed asap
Interesting stuff, what was the mileage of the van before it had these difficulties ?
Nice video , the brick and patio cleaner what acid exact are you looking for in the product? i cant find the exact one you have
Hydrochloric
ACETIC acid - and this time hydrochloric?! - it is listed right on the front of the jug as Acetic aced 20% in the previous video and now a switch to a differnt acid in this video
I have read one study while searching for this info that there should be 1:1 hydrochloric acid and also 1:1 concentrated nitric acid . So 2 ml of water 1ml hydrochloric and 1ml of nitric acid.
hydrochloric, nitric and acetic acids are all used in brick cleaners. so far he has used 2 kinds?!?
Jimmy, grand job mister. You normally mix with launch DPF water 50/50.. what about changing the mix to more DPF cleaner, and what about letting it sit longer..?
He's done a few videos like that. The launch is for soot not ash. He came up with this solution if the ash Contant was too high, and the soot was low
What is the model number for the Launch diagnostic equipment you are using Jimmy, I have the evo129 but yours is much better. Great video.

jimmy will the launch x431 pro elite v+pro5 reset range rover costomers ride height i was told i had to take to range rover so they can do it any help would be grateful
Just woundering have you ever tried oven cleaner on a dpf to clean it?? I use it to clean the vanes on the pd engines when the actuator suck with carbon works every time. Woundering how it would work on the dpf
Are any of the common detergents or solvents any use as DPF cleaning solutions?
After what milage should the car (especially the Renault Trafic) do a regeneration with a normal working DPF?
Everyone guessing what best for the dpf if it wasn’t for jimmy nobody would have a clue what there talking about
What's going on with the merch' links Jimmy? Prices change after you click on them?
Jimmy any chance you could leave a link to the exact Launch device you use please? Thanks

I bought a ford courier from a dealer, returned for a full refund 2 weeks later due to dpf sensor coming on every single day.
I'm back to looking for a van, I was looking at a Berlingo but after watching your videos they don't seem much better.
What small van would you recommend? A VW caddy?
90k miles, no issues on the berlingos for the dpf.
@@Manxlad over all a decent van then? You would recommend? You had a caddy or any other vans in your time Gareth?
Cheers for the reply 👍
@@Manxladwhat year is it?
What are youre thoughts on the launch creader tool jimmy i bought one for my mondeo supposed to do everything
As well as brick acid i use a mix af adblue and water.. works better than the launch chemical. Every time
Nice video as always
Thanks again!
