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 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.
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.
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

Had the same problem, did exactly as you but notice it's hard to get all the areas with the pressure washer, ended cleaning with the flash cleaner £200 but it came like new. It's also highly recommend to change the DPF pressure sensor as it's a common fault. Anyway, excellent video as usual
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.
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.
hi never tried boiling water but will do .good way to loosen soot. with power washing I use hard plastic cv boot on end of dpf secured with clip and secure power wash lance with cable tie it does increase pressure of power wash . boiling water good tip
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.
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.
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.
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.
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!

Wynns off-car dpf cleaner is the dogs danglies. If that solution doesn't clean out the dpf, then it probably cannot be saved. Mercman uses the same method that most garages use when confronted with this problem and most of the time, but not all of the time, this product does the job.
This dirty water goes into the drain, which connects to our car wash’s drainage system, and our car wash has a commercial drainage filtration system which gets cleaned and replaced regularly..
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
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).
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.

Hello there, I am hoping to get some advice before purchase. Vehicle in question 2014 GLK250 w/ OM651 2.1 liter I inspected the vehicle and test drove it today with some findings from my OBD2, it appears there may be some DTCs my scanner is unable to read because it gave a message indicating something along those lines. Detectable codes are as follows: p2201 Nox Sensor circuit range/performance Bank1 P2033 EGT Sensor circuit high bank 1 sensor 2 P2084 EGT Sensor circuit range/performance bank 1 sensor 2 P2201 code repeated Check engine light on and constant. Drive-ability was good, nothing abnormal noted. Tailpipes appeared to have some sort of white corrosion/powdering on them? This is my first experience with a MB diesel since w123 300TD, so quite a bit is new to me. Any advise would be greatly appreciated.The only repairs I could find in service records were for an ECM reprogram, a key replacement, and a non-descript "wiring repair." Only recall outstanding on carfax was Takata passenger airbag.
Hello, I noticed that you were doing all of your cleaning in the same direction as the exhaust flow. I would have guessed you would want to be doing all the cleaning and rinsing in the opposite direction of the exhaust flow, to effectively be BACKFLUSHING the filter - am I missing something or do you think it makes no difference? 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...?
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..
GREAT video! My USA model 2009 GL320 is burning oil like a quart every 500-700 miles. DPF code on, and power loss. Hope it can be removed like you did. What if the guts were knocked out of it to unclog it and you put it back on? Will the diesel still run? Less restriction probably a wonderful thing.
I don't know about the Mercedes diesels, but the Cummins, Powerstrokes and Duramax run great with the DPF core removed. You have to trick a couple of sensors or add a tuner to avoid a check engine light. I unplugged my EGR valve in the closed position and have a check engine light that is on all the time. Since I'm used to ignoring the TPMS warning lights it doesn't really bother me.
My 2015 E220 is returning 25mpg despite having 35k miles and driving mixed motorway/local, with no hard driving either. It's still under used warranty and the dealership have found no faults. Any help/tips what it could be?
Nice video man! It looks like you washed that into a normal ground water drain, you shouldn't do this as the oil and chemicals will go straight to our rivers. It's better for the environment if you at least wash it into a sewer, like through your sink, or even some kind of chemical tank.

Hello there, I am hoping to get some advice before purchase. Vehicle in question 2014 GLK250 w/ OM651 2.1 liter
I inspected the vehicle and test drove it today with some findings from my OBD2, it appears there may be some DTCs my scanner is unable to read because it gave a message indicating something along those lines.
Detectable codes are as follows:
p2201 Nox Sensor circuit range/performance Bank1
P2033 EGT Sensor circuit high bank 1 sensor 2
P2084 EGT Sensor circuit range/performance bank 1 sensor 2
P2201 code repeated
Check engine light on and constant. Drive-ability was good, nothing abnormal noted. Tailpipes appeared to have some sort of white corrosion/powdering on them? This is my first experience with a MB diesel since w123 300TD, so quite a bit is new to me. Any advise would be greatly appreciated.The only repairs I could find in service records were for an ECM reprogram, a key replacement, and a non-descript "wiring repair." Only recall outstanding on carfax was Takata passenger airbag.
Hi, nice job! How does it feel after cleaning? Did you feel that the car is going better when rolling?
100%, i did this to my car, Bmw X3. And the power si better for sure
@@XTCSMarius15 Thanks for your feedback! I'll do it on my 2011 Vito CDI 2.2
What diagnostic software do you use in this video? Seems very comprehensive compared to most
Thats the factory diagnostic software, xentry diagnosis
Hello, I noticed that you were doing all of your cleaning in the same direction as the exhaust flow. I would have guessed you would want to be doing all the cleaning and rinsing in the opposite direction of the exhaust flow, to effectively be BACKFLUSHING the filter - am I missing something or do you think it makes no difference? 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...?
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..
GREAT video! My USA model 2009 GL320 is burning oil like a quart every 500-700 miles. DPF code on, and power loss. Hope it can be removed like you did. What if the guts were knocked out of it to unclog it and you put it back on? Will the diesel still run? Less restriction probably a wonderful thing.
I don't know about the Mercedes diesels, but the Cummins, Powerstrokes and Duramax run great with the DPF core removed. You have to trick a couple of sensors or add a tuner to avoid a check engine light. I unplugged my EGR valve in the closed position and have a check engine light that is on all the time. Since I'm used to ignoring the TPMS warning lights it doesn't really bother me.
Did you do a regen too?
Good video how to …

My 2015 E220 is returning 25mpg despite having 35k miles and driving mixed motorway/local, with no hard driving either. It's still under used warranty and the dealership have found no faults. Any help/tips what it could be?
Nice video man! It looks like you washed that into a normal ground water drain, you shouldn't do this as the oil and chemicals will go straight to our rivers. It's better for the environment if you at least wash it into a sewer, like through your sink, or even some kind of chemical tank.
@Cars And Rentals my garage drains don't do that more do any I have seen. Only commercial premises do that usually.
Give him a break he's trying to help climate warming
In my country you go to jail for what this guy is doing.
My gosh, this stuff is around anyway, it comes out of exhausts, and is washed down by rain. It's carbon.
@@bellezayverdad You should move.
anyone unfamiliar should look into how this problem is addressed on teir 4 compliant farm tractors . Not the answer for all but informative .
What's the solution ?
Did you do a pressure differential test before and after to confirm increase in flow?
Hi where did you get your xentry diagnostic from?
th-cam.com/video/YEZc2_1MBUg/w-d-xo.html
Great job. How much does that procedure cost?
It's a great machine to clean dpf, please watch it. th-cam.com/users/shorts1stnVGyPRtg?feature=share
you must clean the dpf from outgoing pipe
Which scanner do u use for diagnosis
Nice job MercMan can i ask what diagnostic equip you used?
th-cam.com/video/YEZc2_1MBUg/w-d-xo.html
every how many miles you have to do it?
Does it impact the scr unit?
2 easy steps to keep ur dpf clean....
Step 1: Remove ur dpf
Step 2: Use straight pipe
Thats all!!!
Good idea but I thought its a MOT failure if you take your DPF please correct me if I am wrong
@@mrshafiquemohammed it is but I dont care at all.....I care more for my car engine life time than a 500€ fine
@@Greece21 well said 👏
Thanks EPA.
Yep. They turned very efficient and reliable engines with long service intervals into fuel hungry beasts that are down for service more often.
What is name of software that you are using?
Yeah this is way better for the environment
Did you notice a difference in performance of the vehicle?
clean vice versa
👍💪👌
