Fixing the DPF differential pressure sensor error
HTML-код
- Опубликовано: 5 апр 2019
- My 2010 Audi threw a fit and started complaining about having some issues with error codes about the G450 sensor, #P0473 Exhaust pressure sensor 1 and #P2453 Dieser particle filter differential pressure sensor. After the change I did diesel particulate filter cleaning by enabling VCDS DPF regeneration.
Apparently the DPF pressure sensor had failed so I regenerated the particle filter and changed the bad sensor. DPF sensor replacement.
For this fix, a proper diagnostic cable is needed. I used Ross-Tech's VAG-COM HEX+CAN-USB cable and software called #VCDS. Code might also be P2002, part in Germanese is called differenzdrucksensor.

Thankyou. I was looking for this mongrel and it's right on top of the valve cover 😁 you're very entertaining. Keep it up.
very helpful my only comment is ensure you have the exact correct same part number when purchasing new sensor.Then you know all is fine before the adaption process.Thank you for sharing your experience with this issue.
Yap. If it doesn't fit don't install! 🤔
After clearing the fault code you need to turn the engine off. Just clearing the code removes the engine fault light on dash but the fault may still be there. Start engine & then check whether the fault code is truly gone. Preferable stop/start the engine a couple of times.
Great video. Really enjoyed it. I had the same issue with my BMW 528i
Very informative, a very well produced and clear video. Many thanks. Phaeton owner UK
Thank you for the feedback ^^
Thank you for this video. I really enjoyed watching this lol some really funny bits. Thanks again 👍🏿
Great fix and such a laugh too. “It looks roughly like it should “ 😂
Thank you for the comment :)
I just say like it is: if it fits I'm putting it in! 😂
Thanks for the video, it was a big help👍
Very helpful. Helped me solve my issue after checking with 6 useless repair garages.
Thank you! I much appriciate the feeback 😇
@@nerdaxic what is the program that U use for the diagnostic? is is free? Any url link for download it?
@@theartofflying3108 Ross-Tech VCDS. Can download for free but you need their cable to use it.
Me too I spent 400 dollars cleaning and servicing when the dam sensor was bad all the time stupid garage was thinking soot is high when false readings were at the sensor waste of time and money egr and dpf is garbage
Very good video my friend, thank you for posting this , very helpful 👍
I love Finland! best regards my friends!
Thank you so much! Coding II was not avalible for me. This was my method on a 2010 VW Scirocco, 2.0tdi cfhc engine code.
Protocol (G450) procedure

[Done, Go Back]
Hope my comment helps anyone out😊
Glad you found the video helpful, also thanks for sharing the process!
Replaced the DP sensor on my 2010 Volvo V70 a week ago. Volvo wanted around 180 euro for the part, bought a Bosch one from Trodo for 75 euro... Replacing it on the driveway wasn´t a ton of fun under the car above the subframe, but always nice when you get it done yourself, surely saving at least around 200 euros... 🙂👍
Which program you use for your Volvo car ?And did you done the same as on video?
@@vladvlad8390 I only used a IcarSoft CR PRO diagnostic tool.
Did you have to synch the new sensor to the car, as in this video?
Tutorial very useful, cheers for the entertainer, mixing dark humor with the damage, i had a smile on my face the complete video to bad the owl was to serios... , thumbs up and thanks.
Thanks for the feedback, glad you enjoyed ^^
Thank well done, helps me to understand the reason for the sensor.
Parts cannon well & truly fired! If the sensor was faulty it wouldn't regen
then why has the eml not come back on (even if the fault code was removed)
Hello !
Donc il faut programmer le capteur de pression avec vcds pour enlever l'erreur du filtre à particule !?
Merci pour la vidéo 👍
If it fits, it sits 🤣🤣 .
Good content!
Also check the rubber pressure pipes that go to the sensor (at the exhaust and the bit to the sensor) as these tend to perish over time and are cheaper than the sensor itself which may not be faulty.
OK, so there can be a leak in the rubber pipes....
@@SteinarPladsen yes they split.
I searched for the sensor code and ended up on this video. One of my sensors from my 2017 A6 C7 it's actually exploded and I don't have any errors :))
Interesting! I guess if there is no sensor, the sensor values won't be off to trip the code! I bet there is some check in the ECU for that, to see if DPF sensor is alive - might get another code.
Great video,subbed.
Hi, I replaced the faulty DPF sensor but the diagnosis continues to show P2456 error. The stranger thing is that with the engine off the input sensor shows pressure -202 Hpa. What do you recommend me to do?
Thanks for your help.
Thanks a lot for this video! I'm confronting the same issue with my Seat Ibiza 6J. I'm watching videos until my sensor arrives tomorrow! :D
Did it fix the problem?
@@abdassamadboumaiz8641 yes, no problem since then. I bought the bosch sensor
had you to fixe codes or anything else with a vcds after changing the sensor ??
@@abfahim7729 Nope, the light turned off after installation
@@cata94 I hope same will happen with mine cause I have three lights on : DPF, engine and glow plugs
Great video 👌
NICE WORK!
Thank you so much! I had exact same prob with my "VW Golf 7 1.6 TDI BM" and just got a used sensor from ebay for 12€ and now everything works without any errors. I didn't need to set the code at the end.
No problem! Glad to be of help 🙂
So did this work without the adaption properly 4 months later on? I've also brought a used one and fitted it. The lights gone out but I've read soemthing about the soot measuring values could be out now.
@@connorjack4714 no problems. If you read much, you read much 😂
Sometimes better just do it.
Thank you for this very funny and well composed video. Question... could you tell me the name of the music you used around 8:10, during the sensor adaptation? Thank you
Thank you for the feedback!
I can't recall what the song was called, but it was easily available from RUclips audio library. I think I found it with search: 3-5 min ambient.
Kiitos man! Helped quite a bit!
Thanks for the feedback!
Glad to be of help :)
I am surprised that dpf regenerated when the engine management light was on.
Do all exhaust pressure sensors need to be adapted after replacement. I have a 2016 vw tiguan and I might need to replace the sensor (still digging into it). Will I need the computer software to adapt the new sensor? I do not have the software you have, just a fairly basic scanner (Launch Crp129E). Which I dont think has the ability to adapt sensors. Thanks for your video.
My best guess would be that you are out of luck there and need the proper tool to do the adaptation. Look around on local auction sites etc, there might be one on sale or somebody renting one!
You can always install one and ask a mechanic to do the software part.
very helpful thank you
I have attempted the fix this problem with basic obd2 scanner on my bluemotion golf 2008. I get a pressure differential sensor fault. I was wondering if your vcds diagnostic would also work on my car.
Cable I have is the VAG COM HEX+CAN-USB, which unfortunately is discontinued. Ross-Tech still sells plenty of compatible interfaces, any of which I think should work fine with 2008 Golf.
Thank you !!! 🙏🏽🙏🏽🙏🏽
This video resolved problem p2002 bank 1 sensor 1?
Kiitos ! very helpful video !
Love the video
I love this guy
Do we have to calibrate the new sensor? I found there an option on my tester but it ask for min and max value
Hey, can you give me your opinion on mine problem related with this sensor. I got DP sensor fault code like a month ago while doing kickdow on my car with auto transmission, I just got beep beep signal and nothing more, car runs smoothly anyway. After that I went to the mechanic, they just deleted the code and so far so good, no problems at all. They told me that probably dpf was a bit clogged and advised me to go periodically for a bit faster drive in high revs - to help filter cleaning. So, does this makes sense to you? If it really was dp sensor I should get this error again, no matter if they deleted code? Is it possible that this code was received beacuse of partial cloggin of dpf and not really beacuse of failure on sensor?
It could be that your dpf was clogged, gave an error and further driving cleaned the filter taking care of the problem. So resetting the code could be the correct fix there.
@@nerdaxic Thanks man! All the best!
4.7 l/100 good injector clean Fuel pump ✌🏻
Thanks i have a B8 Passat. That doesn't show the DPF symbol in the instrument cluster just ordered VCDS to check what's the problem all Connections look fine i noticed your DFP in the Audi was in the middle of the Cluster
Yeah, the DPF regeneration symbol might pop up on some more general display, it probably doesn't have it's own bulb in the dashboard. Just a heads up that I've noticed that chinese knock-off VCDS cables might not show everything that the ECU has to offer, sometimes genuine RossTech cable is needed for tinkering with it.
Thank you. I've got a sickly A4
Did ya manage to fix it?
Hey I have theses codes on my seat ibiza 1.2 tdi, should I also change the sensor and I wonder if I could fixe it after with a OBD (OBDII/EOBD+CAN)?
P2463 P0405 P0403 P0238.
I would consult a mechanic about it. I do not have the information to help you :/
I had the same error on a Vectra C z1.9dth. This dosen’t fix mai error. It goes in limp mode
Thanks for posting this great video, it was really helpful,what surprised me the most is that you're just a young kid, look about 15 year old 🙂!! i thought it may have been someone around 35 years old doing this sound track, hope you get permission from your dad to drive his car 🤣
My car I bought with my own money 😢
@@nerdaxic life and it's trials and tribulations ehh 🤔 hope your car keeps running perfect now, take care 🙂
You should make posters of that thumbnail. You'd make a fortune.
According my my research, if a RUclips thumbnail has middle-finger in it, click-through-rate goest through the roof. I mean my videos usually get like 1000 views, this is couple of magnitudes more 😂
Hello
I have a 2012 Audi a3 tdi 2l and I have a code of p2002
The car drives fine but check engine light is on do you think I have the same problem with the sensor or could be something else?
Thank you
Check my other DPF video, I think I had something about P2002 there. But yeah, sounds like its possoble, it could be a spesific failure mode of the sensor.
Thanks
Hi there I own Audi a4 2010 its got two issues one glow light and the other is engine management light and when I drive it after while it goes slow loose it’s pickup please help thank
Haq
Unfortunately that is not something I can help you with. Sounds like the computer is detecting some issue and putting the car in "limp mode" to protect the mechanics. Id recommend to consult a local mechanic.
Nice .
You know you're vcds
Mine is being a pain I replaced the sensor and the Plastic pieces that plug into the rubbers kept breaking on the new sensor as well as the old one when trying to replace it eventually I got it to work but the light keeps coming back on I did not however do a DPF region as I don't have the same program as you do
Could take it to a mechanic and aske them to do the adaptation & activate DPR regeneration
@@nerdaxic I work in a garage, it's just being a ball ache lol
turns out i had the wrong sensor... listen this video and he says look at it and make sure its the same. the small hole for the screw was thicker than the original. a quick look on amazon and i found the correct one.
thanks again 😓😁
@@ovseer7230 Glad you got it sorted :)
bro, I have the same problem (a3 2.0 tdi) I bought a new one and it gives me the fault again when I do 10 km, it turns on the check
Did you do the adaptation part of the fixing process? Next guess would be leak in the tubing.
Is possible after change the sensor clear the codes with a basic obd reader? Thankyou
Clear codes, yes probably.
To do the sensor adaptation I'd guess no.
@@nerdaxic so that means even if I put a new one I still will have the issue?
@@joaoteixeira8511 could be that the car can adapt itself over time, but i would take it to mechanic and ask for the digital stuff. Still save bunch of money by changing the sensor yourself.
@@nerdaxic okay thanks for your help
moro tartteeko uutta anturia opettaa ecu:lle vcds:sällä?
En oo kokeillut mitä käy, jos ei opeta joten en osaa oikein vastata tuohon. Saamieni työohjeiden mukaan pitää.
VCDS:n tarvii ainakin huoltovalon nollaamiseen.
So I replaced DPF... then replaced DPF pressure sensor and pressure hose yet I still get active DPF regeneration every third day I drive. I may drive two days in a row in highway where DPF passively regenerates but still on the third day it does active regen. Any ideas?
Did you do the adaptation with the OBD-tool?
@@nerdaxic yes, car was set correctly to see a DPF as new two times already. While driving diagnostics show DPF as completely emty, then fully clogged for a second or two and then empty again. So first diagnosis was faulty DPF. Replaced it but it has not solved the problem so I ended up changing preasure sensor and a hose. Still regenerates every third driving day. Not ever third day but every third driving day. Always like a clock.
Injectors work fine, air flow and preasure is fine, air filter clean, oil is not leaking into the system, oil is low ash for DPF. Bad wires?
@@amrokas no idea
@amrokas hi mate did you get to the bottom of your dpf issue as mine is doing the same.
@@davemcnish4235 luckily I got my car totaled in fortunate car crash few week after my last reply. At that point I had already replaced DPF itself and still had same DPF problems. Now driving petrol :D
Nice Thumbnail 😅😂🤣😁😁😁.
I felt the same way when it appears on mine.
Haha, agreed. It was frustrating!
Do you have reprogram the new sensor or can you just plug it in
Can not say for sure as I am not a car-surgeon, but I'm pretty sure the sensor needs the adaptation. Might work, but the values might be off cans cause "undocumented behavior"
@@nerdaxic hallo
I can not open the login11 to make the adaptation
@@yahyaonline Do you have a genuine cable? Also your password might be different, Id recommend to check RossTech forums for help. Probably someone has already figured it out!
@@nerdaxic hi I buy it new on I only one use it ):
@@nerdaxic its original one
Hello can i go on a big trip without it working because the engine will produce more than enough heat to burn of the particles
If your DPF (Diesel Particulate Filter) sensor isn't functioning, your vehicle can't properly determine when to regenerate the filter. This might either lead to the filter not being cleaned - potentially clogging it up - or constant regeneration, which could waste fuel and even damage parts. Given that it's a relatively inexpensive component (around €15), it's advisable to get it fixed before embarking on a long journey.
Hi my pressure sensor has melted!!! I’m getting a replacement but the connector that connects to the module, what is that sensor?
Mine too! What was your outcome? Did you need a dpf clean?
Replaced it. Gutted the dpf, cleaned out the EGR oil cooler, remapped it. Only for the pressure sensor to melt again, capped it off. Changed the n75 valve due to under boosting, forgot to blank the EGR. So that’s the next step
@@RM-kf7sp ah shiz that sounds like a right mission. I'm really confused, iv got a 2013 Seat Leon 2.0 150 and my where my sensor is I only have one outlet going to the car. All the ones I see online have two?! Where the frig does the second pipe go to
Possível me informar se colocar à vavula blow of e aceite sem problemas erros e desempenho do carro
Desculpe, eu não falo português 🙁
audi a5 3000cc engine. disel the blow valve of the trocar for the original of the car will not give errors in the car on the panels lights on
Please help it is audi a6 2015
Can you tell me p2002
What does it mean
When l clear code it comes back in two days
I'm no tech support and usually ignore these - but to me this sounds like the problem isn't fixed. P2002 is a DPF related code, if changing the sensor and few proper regeneration cycles hasn't helped, there is probably some other hardware failure: possibly air-leak or damaged DPF.
@@nerdaxic tnx a lot for the ansver and help ,at least 10 regeneratio has passed and ended meanwhile and nothing is changed. Audi dealership has checked all sistem and didn't find anything strange or damaged about dpf.last info that they told me is that they will try to put new version of software maybe that help.
A lot of cash is in their pockets and they didn't solve the problem.
Don't know what to do friends around me telling me to turn off egr and dpf on cars ecu what do you think about that.
Tnx again
No clue what's going on. Something is busted for sure! I would recommend against disabling the EGR since having it enabled reduces pumping losses and emissions. DPF you can't disable just by software, and removing it is a punishable crime in many countries as it would slowly kill us all. I think a qualified mechanic should be able to find what's wrong with it, such are cars sometimes.
Hey bro, what will if you don't adaptation this?
No idea but I don't wanna try 🤣
If anyone else has an idea, please comment!
Is it same procedure for Q5?
Changing the DPF-sensor process is pretty much the same. Cant say about the software side tho.
What happens if you don’t do the adaptation ?
No idea. I'd imagine things like zero-value of the sensor would be off, like being non-calibrated in the system. If I was the sensor, I'd give you all sorts of nonsense and errors. I'm no mechanic but I can speculate! 😏
Nerdaxic I talked to a mecanic after I changed the G450 sensor .. he told me that in the VW manual it sais you don’t need to do the adaptation... just plug it . Anyway thanks for the reply. Have a good one. Gretings from Ro.

Dupa ce am schimbat senzorul , eroarea a ramas, am sters eroarea cu programul de diagnoza si nu a mai aparut, in cazul in care esti sigur ca ai schimbat senzorul care trebuie si eroarea ramane trebuie mers putin mai departe cu diagnosticarea problemei , dar la mine a fost simplu, schimbat senzorul pe original , sters eroarea si cam atat, si dpf-ul verificat si a mers in parametri normali

Hi , i have code p2453 , i changed the sensor but the light is still on. I cleared the fault code but it come back again after one day. It’s a Audi A4 2.0tdi 2010. What can the issue be?
Did you do sensor adaptation in the software? Clearing the fault code is probably not enough.
I did not do that. But I don’t have VCDS can I use some other obd tool?
@@alisamad2196 None that I'm aware of. Probably some espensive professional $5000+ scanners or the factory interface. To my knowledge RossTech is the cheapest "consumer grade" tool you can do this with yourself.
In 2012 I had the same fault, 2 months after buying my car. Payd 200€ at Audi to fix this. I dont know why i watch this video. But nice to know how to fix this.
i have also 1,9TDI but my car is from 2006.
i had almost no problem with this car since 2012. Just two Door locks and Brake cylinder in 2018. And one wheel bearing changed last week.
Good to hear that they are not charching like 1000€ for such an easy fix! I was under the impression the branded service stations are expensive AF!
Similar story with my Audi, follow the service book and I havent had any issues in a decade.
came here searching for information on v10 tdi touareg.
yeah it's a little different.
ours is housed on the top of the transmission bellhousing.
yeah.
yeah....
Vw Polo Mk5 replaced - no coding was needed, vcds had no setting for coding lol
Cool! Good to know, glad you got it working! :)
Love The video
why didnt you buy that OWL :) :)
Fault code P2003 opel astra j?
I believe P2003 is "Diesel Particulate Filter Efficiency Below Threshold" which means the DPF is not doing it's job properly. Regeneration might help, but I'm afraid this one might be actual DPF issue instead of sensor issue (which it also could be). Some tube loose or broken somewhere or DPF being clogged. These are just guesses of a medical engineer, I'm no mechanic!
8 month back I clean dpf I now have same problem and error code,my dpf does not automatic clean I dont now why
👍👍👍👍

Finland?
The one and only!
their cable costs like 370 usd man, so is it okay to replace the sensor and drive it to the nearest garage and let them do the adaptation there? is it safe ?
I'd say so. You'll probably get some error code out of it as if the computer thinks there is an issue with DPF, but it can be cleared on the same go. Here the mechanics are super picky, they will only clear codes if they have done the service, which is why I bit the bullet and bought the cable. If thats the case you can ask the mechanic to change the sensor, thats like 5 min job so the bill should not be too much.
@@nerdaxic thanks 🙌🏼🙌🏼
hello, I just changed my EXHAUST PRESSURE SENSOR G450 on my vw golf 1.6 tdi 110hp 2014 , after a vcds scan , everything well till i needed to to the adaptation with vcds , i went to engine block as in your video but the CODING II - 11 on my vcds is greyed out and and I don't have acces there....any ideeas why is that??? can anyone else help me with these problem???
Same problem here, did you manged to resolve the issue?
Rayan Farris I replaced the wright senzor (I have 2 identical on my golf7 - fiind out wich one is broken) after that just deleted the errors and thats it. I talked to a mecanic about the adaptation and he told me that it will work without the adaptation - the senzor will adapt automaticaly, hope this will helpd - also you should check the pipes and all the cables from the dpf, also under your car , if changing the the senzor doesn’t fix the problem
@@ondragho you had an errors or problems without coding the sensor in so far? I plugged a used one in but don't have VCDS, engine light went out also

P.s.car behavior is normal
Lol, DPF sensor or an owl 🦉😂
7:41 if it fits its it. Funny guy
That's not really fixing it.. that's replacing it..
"Replacing the DPF differential pressure sensor error" does not sound like a good title, Im fixing the issue by replacing the part 😉
I wouldn't of bought the sensor... I would of got the owl.
The owl did not fit under the hood :(
Lol cool guy
U basicaly waven't done anything u didn't store new values in adaptation of ash mass
It is possible. These are the instructions I got and it solved the issue - havent had DPF problems since. This is why I advice people to use a competent mechanic instead of listening to a goofball in the internet.
Sucks have to program the new one
Yeah, major hurdle on people fixing this issue themselves :/
Hi. First you show ass att you drive car with cruise control on it , then you show us att you buy BOSCH fake sensor with 2 scruws in it , and your original have 1 scruw ....the you show us that your VCDS have WORKSHOP number 66565......what is this ....china clone ?
That would be interesting if the authorised reseller sold china clones. Nothing I can do with it as a end consumer there if that is the case. The cable I have bought used, but it has been authenticated and registered by Ross-Tech to my company.
Good. Vid
