- This is only to show you guys the steps and key points when doing dpf cleaning on car. This method works for may makes and models. 2 things you need before you start this job is, the spray and a diagnostic tool to reset the value on the dpf Ash volume and enable dpf regeneration while driving.
It is quite straightforward. Find a place to spray the solution before DPF, it can be back pressure sensor pipe or the add blue injector. After you spray the solution, wait for 30 minutes, start the engine, run it for 5 minutes, and then accelerate for another 5 minutes then reset the Ash volume valve at least to 20g. Clear fault code, activate dpf registration while driving, then take the car for a good 20 minutes drive. Stop the car at a safe place, go to live data, check the Ash volume value. Check if it drops below your initial value.
I hope this helps.
Please don't mind my voice as it was freezing cold on that day.
Thanks for watching.
I will be happy to receive your feedback.
Thanks
Audi a6 C7 2,0 CR CNHA -zrobiłem dokładnie tak jak poleciłeś i wszystko jest teraz OK-nie ma trybu awaryjnego(żółta ikonka).Przez ten otwór od sondy wtrysnałem srodek na zapchanego dpf-a.Poczekałem chyba z godzine i odpaliłem auto na 5 min na wolnym biegu a poznie max czyli 2500 obrotów -bo zablokowany.VCDS-em zmieniłem wartosci sadzy wpisałem 20 g , włączyłem automatyczne wypalanie dpf-a w czasie jazdy.Pojechałem z 20 km. Prędkość sie odblokowała i włączyło wypalnie DPF-a (ikonka z dpfem) -po 20 min jazdy ikonka znikła. Jest ok :) Dzięki.Robisz to na własna odpowiedzialnjośc gdy będzie nie przeczyszczony dpf -spalisz auto.Zobacz to nagranie- tu ustawia na 0 a ty ustaw na 20 g.W trybie serwisowym( zółta ikonka) masz poblokowany dostęp do pewnych bloków ze względów bezpieczeństwa.Tu masz co i jak:ruclips.net/video/c10D4WyU0Sg/видео.html
Hi, how did you open this sensor /injector please if you can make a video
Thanks
How that solution can clean dpf if it’s sprayed behind filter in flow? Doesn’t it needs to be sprayed before just behind turbo?
Hello mr. , Im very happy to sharing this video from you, I need you- i"ll be very grateful to your answer, I have problem with dpf, or.maybe not, but when I restored my injectors, since then my AUDI A6, 2012, 2.0 TDI, do many often regeneration, city ride about 120 km, highways-(way to my job)- about 240 km, but before reparing injectors didn"t do so much often regeneration. The mechanincs told me that is not any problem, cause there is no light or showing error, so dont being disturb. But I know that is not perfect and the problem remain, so what you recomend, this video shows simply cleaning dpf, is that the solution? thank you very much for your answers, TADEJ GABRIC, SLOVENIA
Is it possible you damage low pressure EGR?
hi
i have vw passat2ltr exhaust gases getting in the car,could this be bcoz of blocked dpf ? car runs fine no lag or loss of power.and i have spent so much on the car but problem still there.
done lot of tests no leak found.plz help.
thanks
Hello, I wanted to ask, I saw the DPF cleaning video. This product can also clean the exhaust gas recycling radiator for the Audi a6 or you need to do another procedure
Hi.
For Egr cooler or radiator, I would recommend a procedure called engine carbon clean. That will help. This will not help at all.
What value did you get after dpf regeneration? In my Q5, always have 5g after dpf regeneration. It is good?
Hi.
5g is absolutely great. That's is the result you need. It should not hit more than around 38g
Thanks for asking
@@carsEVsvans everytime is start regeneration when is 22g, and is stop when get 5g. Thank you
hi, can i put 2 cans of that solution instead of 1?!
Hi. Yes you can. There is no harm at all. But what I would suggest instead it to do this procedure 2 times will work a lot better. So instead of putting 2 cans once, do it 1 at a time twice.
Thank you for reaching out
Would this method will clean and EGR cooler too?
Error code p200200 particular trap 1 - efficiency below threshold
No it wouldn't. But instead you can use curbon cleaning solutions. Check some videos on RUclips
@@carsEVsvans appreciate for your reply man, thanks
Thanks for sharing. Noticed you have 137k miles? How often have you done this process and have you ever taken off the filter completely for cleaning before?
Thanks
This is only done when necessary.
I did not take anything off apart from the add blue injector as seen on the video.
@@carsEVsvans I meant have you ever had it cleaned by a shop by taking off the filter completely. They take the filter and run the chemicals through it then put it in an oven.
@@drewdub8425 no.
This is a customer car and we do this for many of our customers and it works very well at least 90% of the time. If your car hasn't lost power (has not been in limp mode for a while) you can use this method. You will need to follow the instructions on the solution you use and use diagnostic equipment to reset the value or activate dpf regeneration.
So to answer your question, no I didn't not take it to the dpf cleaning centre.
@@carsEVsvans Thanks. I was just curious because over here there’s only 1 maybe 2 shops then do the cleaning. I feel the services over there is more available. I’d love to try this method but there aren’t really “over the counter” solutions sold here such as this.
@@carsEVsvans you also removed the temperature sensor as seen in the video
are there any warning signs when dpf is due to be checked or issues could start? or does the car warn you? or do you have to know the signs?
For VW, the DPF light comes on. Then possibly the check engine light.
Also, the sign are the typical low on power, rough idle, etc. but that can be a number of things. From what I read the sensor measures pressure and when the light comes on, the pressure within that chamber isn’t where it’s supposed to be.
The previous owner changed my mk6 Jettas DPF filter at 180k miles. The dealer does not do any cleaning but instead change the whole can. The car is now at 240k and the light went on. Generally I’ve read that it should be taken out and cleaned every 60k-75k miles, but that’s just talk on the internet. I’ve reset the faults, did some spirited driving, waited till the active regen finishes cycle, but it won’t go away. The dealer will charge $250 for a diagnoses here in CA, USA regardless because it’s their protocol. All that being said, I’m taking it off and having it flushed by a diesel shop.
@@drewdub8425 thanks for that :)
before spray the solution , what about the engine temperature ?
Cold is ideal. The purpose of the spray is to sock the Ash. Cold is Good. Too hot not recommended
I also have a problem with the dpf filter in the sense that due to the low temperature outside the filter it does not reach a temperature higher than 250 degrees and regeneration cannot be done, I did forced regeneration while driving with the carista and in vain that the ash still does not fall from the deposited filter at this moment I have 27 grams of deposited ash, what can I do in this case?
If the temperature does not reach the required parameters, there could be few reasons why this happens. 1 faulty temperature sensor 2 faulty dpf injector, blocked add blue line or or pump.
The temperature is maintained by injecting fuel or add blue in to the dpf.
So I would check in this area to see why the temperature is not reaching.
I want to say that I don't get any error on the tester that some sensor or something else is faulty, only that it's cold outside, the dpf filter doesn't manage to exceed 250 degrees, I checked what you told me and it doesn't seem to be any of these problems
@@fortzosu09
What car are you trying to fix? If it is audi, check for the add blue injectors.
Fuel vaporizer or pump. Or if you can swap around the temperature sensors.
If you are trying to fix another car, let me know and I'll try send you common issues
@@carsEVsvans The car I have problems with is a vw golf 6 1.6 tdi from 2012, I read the values in real time with a delphi tester and the following values resulted: exhaust gas temperature bank 1 Value 20.0 Celsius degrees; exhaust gas temperature sensor bank 1 sensor 2 Value 20 Celsius degrees; exhaust temperature sensor 1 Value 20 Celsius degrees; Exhaust gas temperature sensor 3 Value 3.9 Celsius degrees; Exhaust gas temperature sensor 4 Value 3.4 Celsius degrees! So in this case I think the DPF exhaust gas pressure sensor is defective and should be replaced? What do you think should be done in this case?
@@fortzosu09
Before replacing the sensors, I always swap the sensors if the wires are long enough and carry out live data test to see if the value changes. And also check the resistance value on all sensor to find out the faulty sensor.
I would say using vcds or odis diagnostics would probably give better live data reading.
This need to go below 5g, 17g is very much
What APP are you using?
I am using thinkdiag.
You can use anything that is capable of spacial functions on vw audi. Vcds is ideal
Did the oil ash volume drop from 0.18L to 0.02L by itself?
Yes indeed. I have set the calculate mass from 64g to 20g. Once dpf regeneration is carried out, it even dropped below 20g.
no, ash is calculated and cannot be cleaned, he just framed the ECU that DPF was replaced
Hello
I wanted to ask you a question about my vehicle?
Hi
You are welcome to ask, and I'll domy best to help. Other people will also help.
good evening, I have the same vehicle as in the video, Audi A6 c7 190hp. engine light on, I changed the egr and egr radiator, and I still have the engine light on and a loss of power. I noticed that the generations are being made, and there is a smell of exhaust gas in the passenger compartment. Can you help me please ?
I also noticed that the FAP regenerations take place when the engine is not necessarily at the right temperature.
I would check for exhaust temp sensor value and coolant temp sensor value.
If there is any fault code, I'll give you the test plan for it
OK thanks for your answer. I don't have a vagcom I will ask a garage to look at it. do you know what to do with the vagcom after changing the egr radiator?
Where are you based pal
Based in Bilston, Wolverhampton
If I had 1 bit of good advice for anyone that wants it ,do not ever purchase 1 of these cars they are expensive money pits
