Mercedes | DPF clean | OM651 220,250CDI W204

[@flyerh]

The carbon is only 20 % of the problem the other 80% is the ash that you can't see inside.Yes you will get a result but it will only last until you put back that 20% carbon because the chemical you bought only dissolves carbon not ash.To dissolve the real problem the ash,you need 25% hcl to 75% water,stop off the narrow pipe and keep filling and emptying the dpf every 30 minutes.The colour of the water when flushing will be dark pink (ash) .Flush out until clear. Now you have cleaned the main problem.

[@AM-dn4lk]

Wouldn't the HCL affect the metal housing of the DPF?

[@Pohmell18]

@@AM-dn4lk It's dilluted and theres one guy who did experiments with DPF materials. It slowly dissolved ash but did not react to metals. Obviously it's a 2 step process. remove carbon deposits and then remove ash. 99% Commercial chemical cleaners just remove the carbon and not the ash itself so pretty pointless considering he took the filter out and went through all that trouble not knowing he didn't actually clean it. Yeah, this video is not about cleaning the DPF but just removing carbon. You could see at the end how bad the flow through the filter still was.

[@cjc1103]

There's some more videos by a guy who experimented with all kinds of chemicals. I'll cut to the chase: Remove DPF from vehicle, soak in a plastic tub (obviously wear gloves, safety glasses, protective clothing) (1) Precleaner commerical drain cleaner (sodium hydroxide) - removes soot, (2) Pool acid (muriatic/hydrochloric acid 32%) diluted 4:1 with water - removes ash. Soak for a couple of hours in each solution then rinse. Gets all the ash out. Pressure cleaning may help rinse but use low pressure or you'll damage the ceramic substrate. 4:1 diluted pool acid won't damage the stainless steel DPF case. Then reinstall and do a forced regeneneration.

[@markanthony284]

Yep ...totally true, if you don't tackle the Ash problem it will only last a very short time, all those so called " DPFCleaners in a bottle" are a short term fix only, you NEED to dissolve the ash for a totally clean virtually as new DPF ....Fact.@@Pohmell18

In Germany we go on the Autobahn and drive full speed for 200 km/h to start the regenerationprocess. The DPF gets so hot, that the soot burns away. In this process no harmfull gasses occur. It's the natural Freibrennen how it is engineered to work.

[@Lars-qp7ys]

If you DPF is full its full you can’t burn it you need too clean it because there is to much ash in it! And before it 200 is not necessary just 130-140kmh in the fifth gear!

[@shawn.0815]

[@WEEChannel-in4wi]

Had one of these 204s with DPF issue. Dealer said it needed a new one! Friend took it to me and I put it on Star. There is a way of forcing DPF regeneration in the car which requires Star and driving the car to a certain temp + over a certain speed for 20 mins or something like that can recall details just now. It worked - Car regenerated it's DPF same day on a test drive and didnt bat an eyelid after.

[@marcodonadel8672]

Had the same issue too, on my 2010 e 250 cdi coupe... The Dpf Regeneration has been forced via software...

[@rich7447]

I'm on my 12th year with the same diesel equiped Ram and have never had any work done on the DPF. It goes weeks between highway trips and have never even seen the DPF regen light come on. The truck is supposed to regen about as often as the range of one tank of fuel. Apparently some owners of the 6.7L Cummins have had particulate filters get full to the point where the truck won't regen (not sure how they get to this point). The solution posted on line is to drive the truck in a gear that has the engine over 2,000 rpm and after a time the truck will start to show the DPF filter level go from 100% to 90% to 80% to 70% at which point the regen will start. There are also reports that extended use of the exhaust brake can make the DPF filter level drop.

[@pocketrocket1237]

I mainly drive my C250 short distances, but I also give it a right good stick wherever possible.

[@soaringspirit20]

Very nice solution! In Russia many people prefer to cut off all DPF, EGR, catalytic neutralizers and other ecological systems even on new and not cheap cars just not to service it. You can easily see for example X5 M40D accelerating with big black smoke behind it.

[@rich7447]

It is popular here in the US. You can get a lot more power out of a deleted diesel.

[@SW38MP]

I think it is time to make the DPF structure easier to clean. It is not eco-friendly to use special equipment and solvents forever. The manufacturers should change the DPF structure so that it is as easy as replacing the engine air cleaner.

[@antoniohinojos3808]

😏

[@victorwilliams4026]

True.

[@saschastalberg384]

Such problems only occur when driving short distances. My Mercedes regenerates its DPF after exactly 1000 km and everything is fine. The vehicle now has almost 300,000 km with the first DPF and I know people who are still traveling over 800,000 km with the first DPF. The problem is the people who buy the wrong car. Diesel is for people who drive long distances. Active DPf regeneration can only begin after 10 km. Then another 20-30 km are necessary to complete the regeneration. if someone constantly drives less than 10 km, they definitely have the wrong car. The DPF is full again after a few weeks.

Your mileage doesn't match between both diagnostic screens (0:46 & 5:55). It seems that you have a 2nd car where you want to show us the "cleaned" DPF. On the other hand, ash content is very important it shows how much ash remains in the DPF after all the regenerations. In this case a forced regeneration would also "clean" the filter.

Hi, you should wash it backwards to really get it clean! You dont want to push the soot and ash deeper into the pores of the material but to take them off and out. As you see on the video, most of the flow is up from where you are trying to push water in.

[@mercmantips]

Yes that is a good point but on this DPF the reverse side does not allow good access with the jet wash, so i find it more effective doing it this way

[@adelestevens]

A quick note about DPF problems... Don't assume the DPF filter is blocked when the warning light comes on. There's one thing you must check first. Always.. check the air filter! True story........ We had a Honda accord idetc and it was always kept fully serviced by Honda dealer (at considerable cost) , when one day the DPF light came on. Honda regenerated the system (£175) It was ok for a month and the light came on again ,Honda regenerated the system a second time for another £175 and warned that if it happened again we would need a new DPF filter for over £1k. At that point I decided to have a look myself and started at the air intake. The filter paper was like a black block of goo coated with dust...even though it had supposedly been changed twice by the dealership! One new filter later and a run up and down the local fast road...light went off and car came out of "limp mode".

Hello, I noticed that you were doing all of your cleaning in the same direction as the exhaust flow.

I'm getting ready to do this on my TDI and never done it before, but logic would say to backflush rather than forward flush...?

[@mercmantips]

Yes you are correct it will be more effective if you do it the opposite direction of exhaust flow, but on this case the opposite direction of the DPF has a long exhaust pipe which is curved, so the jet wash wouldn’t be as effective opposite way, thats why i done it this way because i can get in really well with the jet wash..

When I took the car back to the garage I was told that I need to replace the DPF having already spent over £300 . Any advice would be much appreciated

It's a great machine to clean dpf, please watch it. kzbin.info1stnVGyPRtg?feature=share

Will this work for gasoline engine catalytic converter?

[@ajkpark]

sounds good, but I heard, the wet method of cleaning is not so good because of residual humidity and water will stay in the filter and around and can cause going rusty ... is this right?

[@teem5642]

I doubt that. Once the engine gets hot, mind you this is the exhaust side, it evaporates. Vapour will travel out of the exhaust with the force coming from the engine. It will come out just as normal exhaust would

[@SDav21]

I wonder if they'll design these systems to work better down the line. They shouldn't get blocked or at least Mercedes should offer 1 free replacement on every diesel car to deal with emissions. With this lockdown everywhere diesel cars won't be driving and if they do, it'll be very short distances which isn't good.

[@mercmantips]

Well to be honest these diesel cars are not designed for town driving, so if your mainly going to be doing town driving you should be driving a petrol, a diesel engine is for the motorways..

[@SDav21]

@@mercmantips Agreed. I mainly do motorway driving but now with all the lockdown restrictions in my country, I now only do a short trip once a week to the store. So I worry now about the dpf. It is a 2015 W212 E350 Bluetech.

[@JJ-zg1hh]

Don't worry. We'll all be driving EVs soon so this nonsense will be consigned to the history books.

[@SDav21]

@@JJ-zg1hh I don't think it will be soon. Plus I like 6 and 8 cylinder diesels. They sound so strong and robust. Makes a car feel imperious. Or even a 6 or 8 cylinder petrol that is silky smooth. I don't want electric just yet.

[@JJ-zg1hh]

@@SDav21 you may not want them but the environment does. The contents of that DPF filter says it all. Plus its carcinogenic. Give me a Tesla any day.

[@JuanCarlos-qm5uk]

nice vid but a blocked dpf is only a symptom, they are able to clean themselves up. the root cause of why it gets blocked need to be addressed, otherwise it will come back after a while.

if i cant find this wynns cleaner in my country what alternatives can i use?

[@lukasspike3685]

You can use pipe cleaner (granulated) and hydrochloric acid. Watch the channel from (pfuisi). This guy show’s this method. Best regards from Polska/Germany... Łukasz

[@michaelg8284]

Hi, nice job! How does it feel after cleaning? Did you feel that the car is going better when rolling?

[@XTCSMarius15]

100%, i did this to my car, Bmw X3. And the power si better for sure

[@michaelg8284]

@@XTCSMarius15 Thanks for your feedback! I'll do it on my 2011 Vito CDI 2.2

Does clogged DPF causes low acceleration in my 20 yr old OM646? Mileage is 183k km on odometer

[@markchester7584]

Never knew you could wear what’s found in a DPD.

Some vaules shown on diagnostic software are not the same. For example, total distance is on the begining 145.000 and at the end of clip is 65.000. Why?

[@stevenj6421]

also use the pressure washer in both directions

[@michaelbenoit248]

Thanks EPA.

[@rich7447]

Yep. They turned very efficient and reliable engines with long service intervals into fuel hungry beasts that are down for service more often.

[@antoniohinojos3808]

Fill level is determined by mileage no? Once you reset the interval, it thinks its just a fresh DPF.

[@FatihSeydioglu]

Thank you very much !!

[@no-damn-alias]

why not start the manual regeneration? Or reset and have a spirited drive or rent a big trailer if you have a tow hook

[@MrGuvEuroman]

Why didn’t you do a forced regen?

[@Modders4lifeUniqueModz]

Was thinking the same thats what i do on mine

[@aeroflopper]

But the question is what blocked the dpf on such a low mile car? it will be back...

[@mercmantips]

Because the owner drives to work and back everyday which is a 3 mile drive each way in town the engine does not even reach normal operating temperature before the end of the journey, once i do this clean i tell my customers to go on a long journey every so often to give the engine management system a chance to regenerate the DPF..

[@69ahmed]

@@mercmantips hi mercman I have a 59 reg Mercedes E350 w212 40k on the clock and I have a dpf problem. Where do you base so I can bring the car to you ?

[@69ahmed]

@Martyn Watson thank for reply I went for a road trip to Sheffield from London And it cleaned everything out

[@mohammedshaji9785]

Good job.It shall conduct all CRDI engines up to 100000kms to get good performance... EGR also clean for thebKms to get best performance of Turbo chatger

[@rich7447]

I would be concerned about an engine that is only guaranteed to get good performance for 60,000 miles/100,000km. My current engine really wasn't broken in until around that mileage. No need to clean the EGR, just unplug the valve so it can never open. Pumping soot back into your engine is a bad idea to start with. If you want to keep your turbocharger at peak performance cool it down properly. Engine shutdown delay systems make this pretty easy (vehicle runs until turbo temps drop to a level that won't cook the oil).

This can be on W212 350 facelifted Bluetec too?(V6 3.0 diesel Euro6)
