A good video but I HATE the too loud and intrusive music. It does not need it. A well explained video.

Very useful to know when the DPF is a common problem, great video Mercman Tips

Great video, straight forward and detailed now I'm off to clean mine 👍🏾

Perfectly explained, I'm gonna do this now, thank you for uploading this video 👍

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

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.

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

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.

Great useful information!! Smashing it as always Merc man!! 🚘🔥

Excelente aporte , muchas gracias .Saludos desde Rio Gallegos Argentina

You are a super chill dude, the way you handled the criticism below is commendable

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

Love these type of videos

I never had the idea to boost with hot watter. It's nice because the DPF and catalyst can be at more than 200°C (390F) thanks for the tip

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.

there's nothing like a good DPF porridge! Just like grandma used to make.

Os resíduos estão a poluir o ambiente da mesma forma, ou a água que sai do fpd vai para uma zona de tratamento? Acho que nao

Which scanning tool or program do you use to analyze these vehicle with?

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.

nice video! what software and hardware are you usung to check?

This just happened to me, needs cleaning as well. Shame I am nowhere near your shop, would have loved to see you do it :)

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?

Emitting emissions to clean emissions cleaners. Do you clean your emissions cleaner's emission cleaners with that?

hello, how did You reset the DPF in Xentry? thanks!

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.

I think it's more important than cleaning to manage the filter in the proper way before the dpf warning light comes up.

How did you reset the dpf management light after mate or does this automatically reset 👍

Would it be possible for you to do a video on changing the vacuum pump on a w204 C250 cdi

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.

Nice Channel! Is that strategy almost for every Cat useable?

Have you got a video on removing the dpf. Dosent seem to be alot of tutorials on this model

what part of London are you based? do you have a website need to book my car in

It’s cleaner than thé garage wall

What diagnistic tool or software are you using ? Thanks

every how many miles you have to do it?

Did this method reduce the ash content of the DPF too?

Nice to know he will be drinking that in a few weeks !

Why not cap one end of the DPF and fill it with the cleaner? Just makes sense. Great video!

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.

Perfect Job thank's 👍

This is the good way to clean DPF, egr, intake, i never use produtcs to put in the tank

Thank you very much !!

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 had my DPF clean & flush ( DPF wasn't taken off the car ), replace a pressure sensor also regenerate and the issue still remains ( engine management light on ) . 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

Which scanner do u use for diagnosis

Whats the normal shelf life of a merc filter ? Im ford we expect 150000 miles ish

Does it impact the scr unit?

Hi where did you get your xentry diagnostic from?

Did you notice a difference in performance of the vehicle?

Great video

Hi, nice video. Which software / diagnostic tool did you use to show the DPF values? Thanks

Wicked video brv....thanks so much

Hey i have a question i have a w204 c200 2007 can i do this like your video because on the 2007 year w204 the DPF and the CAT are together?`

will we also get rid of the ash in this way?

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.

Gracias por no contaminar. Me gustaría hacerte beber todo lo que sale del catalizador.

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...?

Good job 👌

would it be a good idea to boil the whole filter in a kattle and just replace the water a few times?

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.

What is name of software that you are using?

Hi mate, thanks for the video. How difficult was it to remove the DPF from the car? Cheers

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.

Excellent

Any ideas how to get a dpf temperature sensor and install it, preferably not from a Mercedes dealer.. Cheers

Will this work for gasoline engine catalytic converter?

Je viens de voir cette vidéo. MERCI POUR L’ENVIRONNENT.

Awesome.

Hey MercMan I’m looking at a S300 W222 Bluetec. 30K miles. Should I stay away from this motor?

Dish washing detergent and hot water works just as well. Owh, and make sure you catch the sludge to be treated properly off site.

Hi, Mercedes e class 220 is the same ? My car doesn’t have power (speed) is the because of the DPF block or EGR or turbo ? Can you plz help me out.

Great job. How much does that procedure cost?

When you think this feature has been made to reduce pollution !!

What are the symtoms of clogged filter

Does the full exhaust system need coming off

What diagnostic software do you use in this video? Seems very comprehensive compared to most

Hello Mercman how much do you charge for a fully clean and how can i contact you?

Nice, All the dirt goes now to the Thames River.

Did you do a pressure differential test before and after to confirm increase in flow?

Got a funny feeling mr muscle oven cleaner would be as effective as the purpose made cleaner haha

Did you do a regen too?

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

which diag you use ?

where does that floor drain go

Can we do the same process with a GL350 bluetec.?

Sehr gut👍

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

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?

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

I own a Ml320 Bluetec and P2463 Fault code is on. How much do Mercedes mechanics charge for Dpf cleaning?

Nice job MercMan can i ask what diagnostic equip you used?

I wonder where that dirty water goes.. Well here they have „eco” filters

What do you do with all the waste?

Well the Dpf in my petrol car has been in perfect condition always

Does DPF blockage cause white smoke in exhaust..!

Mercedes do not have an automatic dpf regeneration cycle?

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

you must clean the dpf from outgoing pipe

We are cleaning warranty and testing after fitting the vehicle 👍

Thank you
