A Diesel Particulate Filter (DPF) is an essential component in modern diesel engines that captures harmful soot particles to reduce emissions. Over time, the DPF can become clogged, leading to decreased engine performance and increased fuel consumption. Cleaning the DPF regularly is crucial to maintain optimal engine function and avoid costly repairs.

Have cleaned dpf in my 2008 x5 by using hot water in a garden sprayer connected to pressure sensor on filter. Just warm car up and give little squirts fron sprayer, great results.

[@TheKeenMechanic]

Nice one, whatever gets the job done. Thanks for your message buddy🤝

[@Infj-62]

Thanks for the video sir, most patio cleaners have sodium hypochlorite as an ingredient which normally rusts metal like you wouldn't believe so not sure about this solution

[@TheKeenMechanic]

Tried and tested on stainless steel and worked the best. Would not recommend it on mild steel

[@Infj-62]

@@TheKeenMechanic Fair enough if it's been tried and tested, hard to prove I guess without cutting it up years later but maybe ok as a one off or as it only needs doing infrequently. Thanks for reply sir 👍

[@TheKeenMechanic]

@@Infj-62 I got the idea from a scientist who tested both chemicals on stainless steel and had no reaction. Depending on the grade and purity if the stainless sometimes it might discolour it but if well rinsed it will not corrode the metal. I have personally tested it many times and no issues

[@mrmusic1880]

I've been so excited to see this one! May I ask a few questions? Are these cleaning products easy to get, or are they more market specific? And would it be possible that if someone less experienced than you did such a job that the ashes would maybe clog up the filter, or does the rinse and stronger chemicals take care of that?

[@TheKeenMechanic]

Hi and thanks for the great questions. These chemicals are available in any hardware shop. The drain gel is a world wide well known brand that you should be able to get in any supermarket. The brick and patio cleaner contains hydrochloric acid which you should search for if you can't find it under the same name in South Africa. Just make sure to wear some gloves and face protection as this stuff is strong and can cause serious problems if it went into your eyes or skin. Glad to hear that you are enjoying the content. I have received very good feedback so far which makes me feel good to be able to help so many other people all over the world🙌🙌🙌

[@mrmusic1880]

@@TheKeenMechanic Thank you so so much for the highly detailed reply, I truly appreciate it!! Very good to know I will definitely keep this in mind! One more question, sorry I forgot to ask in the beginning! Does it matter which side you put the chemicals and water in, is it best to put it through the dirty engine side or the clean outlet side?

[@TheKeenMechanic]

@@mrmusic1880 Thank you for another great question. I actually didn't explain this in the video but if you noticed I back washed it not to push the dirt further into the filter. Feel free to ask as many questions as you want. Just hope I can answer them😀

[@mrmusic1880]

@@TheKeenMechanic Ok good to know! I really appreciate your reply and answers to my questions, thank you! If I find any more questions I will be sure to ask! Thank you😁

[@TheKeenMechanic]

@@mrmusic1880 No worries, my pleasure.

[@HalfaJobJames]

Thanks for the video, just out of interest do you know what your pressures were at idle before and after cleaning? Just done mine and drying it overnight before refitting tomorrow. 😊

[@TheKeenMechanic]

Sorry, mine was not clogged up to the point that will cause issues. I didn't measure the pressure before and after as I had no faults. It was part of the preventative maintenance whilst I had the engine out🤝🏻

[@HalfaJobJames]

Ah no worries it was only out of interest! Makes sense to whilst the engine is out for sure! Thanks for the quick reply!

[@TheKeenMechanic]

@@HalfaJobJames No problem, glad you enjoyed the video🤝🏻

Great guide, probably simplest on the YT, so I will follow it in near future. Quick few questions though: 1. do you need to remove all temperature sensors ? It looks like you got them off, but I'm a bit afraid that they will fall apart. 2. Are those chemicals safe for catalistic converter which is a part of my DPF box and can't be separated. Thank you for any answer! D.

[@TheKeenMechanic]

Hi and thanks for watching. Definitely remove the sensors otherwise they well get damaged. Those chemicals have been tested extensively by a guy who is a scientist and knows his chemistry. Do some research and you will see for yourself. It will discolour the metal a bit but it will not cause any damage to the stainless steel or the precious metal in the cat and dpf core. I have personally used this method on many cars and never had any issues. Carry out with confidence and wear eye protection as these are strong chemicals🤝🏻

[@wajdulis77]

Hi. Thanks for quick answer. I'm not questioning the method here, I think this video is the only one mentioning the ash removal and I can clearly see the proof with my eyes. I've found different YT video where different chemicals been tested (maybe the same as you mentioned) and 2 stage clean is recommended, for soot and ash separately - again you are only one doing this. All off car dpf cleaners available are mostly concentrated on soot, I do not think my car got problems with that at all. Simply almost 700 regen cycles left enough ash to restrict the flow and I want to focus on this. Exact same chemicals are available here, do I simply do what you have done. Have you left the dpf to soak in or flush it promptly at any stage of your cleaning?

[@TheKeenMechanic]

@@wajdulis77 You can soak in and leave in the brick cleaner acid. I spent several hours soaking, rinsing, shaking, rinsing and soaking in the chemical for best results. If you follow my tutorial you can't go wrong. Some people use a pressure or a power washer but I was afraid in case it damages the core. Best of luck and hope you make it as clean as new. If you are doing this on BMW you can use ISTA+ diagnostics to register the cleaned DPF as a brand new one which should reset the count.

[@wajdulis77]

@@TheKeenMechanicgot all the info and already bought the stuff, just waiting for a bit warmer weather here in UK. Sadly I do not have BMW yet (got ISTA+ though) but in my current car I can reset all DPF adaptations through dedicated software as well. I'll definitely come back with the results; it just can take some time though as spring is still 2 months away. Thanks again!

[@TheKeenMechanic]

@@wajdulis77 No problem. Take your time and do it right🤝🏻

[@TrotterSoccer]

Great to see! Same DPF filter for the M57 maybe? Same procedure will work?

[@TheKeenMechanic]

100% will work. Just don't use pressure washer

[@Virvirko88]

Did it become clogged again after some time, or it serves you without problems after you cleaned it?

[@TheKeenMechanic]

No issues at all so far. Car is used on long journeys daily so it regenerates ok and keeps dpf in good order🤝🏻

[@desmondgreatdevil]

Do you let it do dry off before installing it back?

[@TheKeenMechanic]

You can let it drain overnight and blow it out a bit with compressed air. You can also install as it is, car will smoke a bit but after it warms up it will be back to normal in a few minutes🤝

[@TheKeenMechanic]

Thanks for watching

[@samkrneta2120]

Did you get any codes when you re-installed it?

[@TheKeenMechanic]

Hi No never had any issues with codes after installation. Make sure to reset the dpf with ISTA+ as if you are installing a brand new DPF😉🤝🏻

[@kenfisher-fd2qc]

what concentration of NaOH and HCl did you use?

[@TheKeenMechanic]

Sorry I can't answer this question. I had filmed this last year and disposed of the packaging at the time.

[@slippy1404]

But didn’t it work on the car?

[@TheKeenMechanic]

Hi, It worked but it generated an error for limited life left. After cleaning you have to clear the values and update with ista as if you are installing a new dpf filter. Basically you are telling the car you have installed a new dpf filter. This is a good way of saving a few thousand £€$

​@@TheKeenMechanicYou can reset DPF with Bimmerlink also, and you get another 250,000 km/around 150,000 miles driving. Can be of interest to make the cleaning before ten years and 200,000 km/125,000 miles. Maybe the ash (and soot) is not that burnt to the "walls" then.

[@TheKeenMechanic]

@@leiflillandt1488 Always good to clean as often as you can but it is difficult to remove so some people just want to drive and sell when it starts causing problems
