Nissan Qashqai 1.5 Diesel Intermittent Warning lights fault fix P0472

[@oyetolaawojebe8018]

This is miraculous! I’ve had exact issue with my Qashqai close to a year which led to MOT failure. Nissan changed the air pressure sensor and battery but issue persisted. Upon stumbling across your video, I tried the procedure which took less than 1 hour. To my greatest disbelieve, all errors cleared after about 7 miles of driving and without using an Obdator. My car has remained error free for over a week. Thank you for posting this video.

Great video. Saved me 1700 pounds. Took the car to the various top garages in the town and nobody could figure out what the problem was. One garage told me that they would need to change the whole DPF unit and would cost me 1700 pounds. I had no other option as my car was due for Mot and road tax and with these lights on the dashboard it would not pass MOT and so would not be able tax the car. So essentially useless car sitting in the garage. Then I luckily stumbled upon your video and followed your instructions and hey presto....everything sorted. All lights gone and passed MOT with flying colours and car back on the road as new. Can't thanks you enough. God bless you.

Brilliant video sorted my problem, I would like to add that I found it really tough to get that break cable round the bend as it was blocked solid. After about 20 unsuccessful attempts I squirted some WD40 down the pipe and left it for a couple of hours this helped by both lubricating the rotating cable and softening the blockage. I kept removing the cable and wiping the black gunk off it and repeating until eventually got round the bend and cleared the blockage. The blockage test with the piece of paper was a great indicator that all was well. At one point I had tried to clear the blockage with tyre pump and adaptor so I knew the pipe was totally blocked. I think a wider pipe to the sensor would prevent this fault occurring. Some of my warning lights went out as soon as the blockage was cleared others took a couple of days and several restarts. Apparently if the engine does not detect the fault after several restarts it automatically clears all the warning lights (nice one nissan) I came very close to giving up a few times so I hope this will add to the brilliant video and encourage people to keep trying until the wire breaks through. I am not sure how the engine uses the information from the exhaust pressure feedback sensor but since clearing the blockage my car seems to be running much better. Many thanks to Phil Jenkins for taking the time and trouble to make and post this video, my car totally fixed for £0.00

In my case turbo was worn out so everything was full of oil wich is probably the reasson why this happens.

[@cadenmilo8652]

Dont know if anyone cares but if you're stoned like me during the covid times you can stream pretty much all the new movies on InstaFlixxer. Been streaming with my brother for the last weeks =)

[@paytonnova9908]

@Caden Milo Yup, I've been watching on Instaflixxer for since november myself :D

[@stdavidboy]

Done this today, cleared out the pressure pipe and cleared faults. Thanks very much for your time in listing this.

[@justinconcannon9289]

Absolutely brilliant!! You do panic when warning lights come on but this saved an expensive trip to Nissan, after a little perseverance sorted the problem perfectly,, thank you so much

[@craigdoon]

Phil, thank you so much for this - I’ve now done this process twice in two years and it works every time. You’ve saved me a fortune I’m sure. Much appreciated.

Awesome, had this issue for quite some time, the code that saved from a borrowed scanner a guy gave me lead me to this video, saved me a lot of time and €€, after all didnt need to buy a scanner to properly figure out the issue. 10/10

[@Wago1995]

This is what I have on start up! Thank you so much for this video dude I got an obd scan and got circuit low p0472 code for the pressure switch! Easy change also

[@garethcook6156]

Worked an absolute treat thank you. Did the the paper trick at the beginning and had nothing blowing through. Definitely need to persevere with this, after just over an hour of trying i used WD-40 and walked away for another hour as mentioned above, cleared it straight away so would recommend spraying some at the start and letting it soak in and do it’s magic. Only issue I have now is the orange engine management light is still on, tried pumping the accelerator 5 times and taking it on a 20 mile drive to see if that would work but had no joy.

[@leonardtelford6324]

Thank you for your brilliant video. I was getting really stressed out about this problem and my car was up for M O T . All the lights coming on, would be a definite fail. Most mechanics don't seem to know what to do to solve this problem and all they can suggest is changing the censor, at a considerable cost, with no guarantee that it would work. Anyway after finally coming across your video and after searching for a long time without finding the exact same issue as I had with my car. I was delighted to find a fix that made sense and could work for me and it did! Yes it's a bit fiddly and I found it helps if you gradually use shorter lengths of the cable sheath until you work the cable wire right through the pipe. Nevertheless it is a fantastic fix and my car has just gone through M O T, no warning lights in sight! What a relief you are a star sir. Thank you again.

[@LisaaccountGriffiths]

Brilliant worked a treat followed this video did whilst pipe still on so no need to get removed. Pipe was blocked. Once blowing clear all errors went off. Driving a full day no issues. Didn’t need a diagnostic machine either to reset any errors. Husband is over the moon now 👍👍 thank you so much!!

[@tonymillward27]

Many thanks for this video it was a good send and sorted the problem. Just got rid of the warning symbol after my pumping the accelerator 5 times with the ignition Key turned to 1st position. Brilliant!

[@35niller]

Super video ...also helped my problem..... My pressure pipe was tottaly stopped, have to disconnect it and used heat to loosing it up.. but no warnings at the dashboard......works just fine..... saved me for 2-3000 dkr...... Thank you very much for a great video.....

[@FlyingHigh99999]

Cheers for detailed video There's another video similar on YT, but I just could not get that cable round the 90 degree bend. Your video, shows by wrapping the casing around the cable it allows the drill to do its job. Worked a treat. Your a star, cheers Phil

[@mechanoid5739]

A very neat solution! I love it when the dealerships get out the parts cannon! .....NOT!

[@robertgordon5860]

Thanks for all your help. I just finished doing this today and after many attempts plus a spray of WD-40 2 hours before I started , worked great. My car was driving fine apart from the warning lights coming on but didn't panic after watching your video. 👍🇮🇪🎼

[@JayW-44]

Had this problem on my Juke, this solved the issue, thanks for posting the video. Probably saved me a wedge of money!

[@raf.krolewski]

Nice job! Can we use some carbon remover to solve the clog down the road?

[@rameshcruz]

Thankyou for this Video, I had the same problem, Sorted out perfectly.

[@nazarethpa1833]

Hi Phil. Please can you tell me precisely what you push or pull to remove the black plastic electrical connector from the top of the sensor. At 3min 09 seconds you remove the block but I cant see what you are doing to remove it. Precisely what are you doing, and to which bit? I have looked and fiddled with mine (I dont want to break it) and nothing seems to move or release the block. Thanks. John Collyer

[@benjamindewaele2469]

Bonsoir 1000 merci j ai eu le même problème j ai commencer a 14h00, j'ai fini a 22h30 laborieux. J'ai insisté avec wd40 et enfin réussi un nuage noir est sorti le soulagement. Merci encore

[@billvekas3465]

Amazing you are a genius.

[@JackScott-95]

If the pipe isn’t blocked and plenty of air coming out then I’m guessing it’s the sensor?

[@b.j.dejong4283]

Today I was driving on the high way with cruise control and suddenly, cruise control stopped and I saw the red engine light. I could not switch the cruise control on. After a few minutes red light went of and cruise control worked again?? Is that the same issue as discribed in the video.

[@FrankyN02]

As I have the same issue with my Duster 1.5dci I ask myself if it is possible to blow this tight pipe with high pressure compressed air. What do you think would it free the pipe ? Or does it damage turbo or something else ?

[@bassmonkey1982ownage]

Recently had the same problem it happened back in January 19 took it to a garage and they replaced the exhaust pressure sensor and I replaced the battery but then again it happened again in November 19 after some digging around to find out the problem I found out that the exhaust pressure sensor pipe was infact blocked which was causing all these errors. took it to a garage and they had no tool or any idea how to undo the 11mm nut on the end of the pipe, I had already bought a new pipe from Nissan for £25 so after rounding the nut a little bit I suggested that they should cut the pipe and try a 11mm socket on it so they did and hey presto it came undone I turned off the errors after putting all the pipe back on started it up and fingers crossed it's all sorted. Hope this helps

[@iranazad-vo9qd]

Hello. Dear friend my car has the same problem which repair garage did you take me to so that I can fix it? Thanks

[@bassmonkey1982ownage]

@iran azad any garage that will know what the problem is , it's just a difficult place to get to as there is 2 pipes close together and I ended up helping at the garage as we just cut the pipe off in the end and put a new 1 on its call a boost sensor pipe

[@Taner-Aydın]

Thanks for video. How was it before you drilled the hole? Wasn't he blowing air from there?

[@larchielad]

Managed to clean the pipe but light still on after i reset it. Any ideas?

[@nikroche2621]

What engine is this o?..Im struggling to locate this on my 08,Qashqai +2.....

[@mka70]

Nice one!! Going to try this on mine. It's only done 37k, but I reckon it hasn't been looked at at all by previous owners, so best to clean the whole system up. One thing that I'm not sure of though. Is there any danger that soot in the pipe may get forced down into the turbo or EGR system? Sorry of that's a basic question, I'm just not sure where this pipe come out. Also guessing though that, once you start up again (without the sensor.....any loose deposits may get blown out? Thanks in advance!

[@philjenkins3499]

This will cause no damage as this pipe comes off the back of the manifold and will not damage your car in anyway

Does this work for ash too? Or just soot? My warning light was been on all week and it’s showing code P242F, ash accumulation... Thanks!

Measure the length from the sensor to the DPF.

Done exactly that only I used electrical cable one strand still in sleeve, pushed it down loads of black slush, done the paper test very weak before and very strong after, can anyone tell me if there is any fluid I can pour or squirt into the pipe??

Hi everyone, I'm having the very same problem and have tried having a look myself but don't feel confident enough to tackle the problem, so my question is anyone around the Leeds Bradford, even lancs area (were near to colne burnley) and would have a go at this for me, I would be willing to pay something for your time just don't have money for a garage at this present time. I would be ever so greatful as this is causing me somewhat anxiety everytime I get in the bloody thing. Thankyou.
