How we clean EGR Valve, Intake Manifold & Turbo without removing!! using DPF Flushing cleaning fluid
Вставка
- Опубліковано 25 вер 2024
- Here we show you how to clean the EGR valve on our van using DPF flushing fluid to clean the soot particles.
This fluid is designed to soak the in the dpf but we are showing an alternative method we use.
we have experienced 100 percent success rate using this method with our vehicles.
spraying it through the inlet the fluid will Go through the entire engine intake system and reach the valves, EGR, Turbo, inlet manifold etc.
Vetech 5L DPF fluid is sold at GSF car parts or any parts alliance shop.
Wynn's 5L DPF flushing fluid is also suitable.
for stubborn vehicles you may need to repeat the process a few times. letting engine cool down before each process.
it's best to spray it as close as possible to the turbo inlet.
be aware of the risk of hydro locking the engine if not done correctly.
we are simply showing you how we do it. we are professionals. we accept no liability for any damages or losses as a result of you copying this procedure.

Dude I was about to spend £880 on a turbo but this actually worked.
Been mechanic 21 years but not ashamed to say I have learned a lot from you. Channel making my life so much easier
Glad to hear it helped
@@rmartin6307 thanks for the support 🙂
Won’t this fluid harm the turbo and might also end up in the combustion chambers ?
I'm gonna try this.. I've got 260000km on a turbodiesel and have never cleaned it.
Jimmy I have the revive kit where would U put it in on a 2016 2.0 Citroen Relay please
I did an obscene amount of research into how to clear out/improve/fix my clogged up truck, and decided to go with the method in this video. I already had a little pump-pressurised spray bottle, so i went online and bought wynns DPF cleaner and put about 1.5 litres down the pipe that takes air into my turbo. I managed to use the pipe from my jack, to keep the revs at 2000 by wedging the pipe between the seat and the accelerator (seats move, so its the perfect adjuster!). My truck engine spewed loads of white smoke down my street during the cleaning, and then when i took it for a run afterwards the engine sounded better, the turbo came to life and drove so much better, my truck mustve really needed it, mustve really had a lot of carbon clogging things up (like the turbo and inlet manifold especially i think)
(worth noting as well, that a few days ago I cleaned out my turbo specifically by using this method - ua-cam.com/video/1EC5Zi3_Z30/v-deo.html).
I also removed my EGR Valve and EGR pipe (because they are right at the top of the engine and only need to take off a few bots) and cleaned them out with a mixture of 3 cups hot water, 1 cup vinegar, half a cup of fairy, and a splash of white spirit. i just looked up a couple videos on EGR valve cleaning because theres bits you want to clean and bits you dont. scotty kilmers video is good on EGR Valve cleaning
did you use the Wynns "off car" def cleaner for this ?
Just wanted to thank you, did exactly what you showed on a Skoda Superb. The crap that came out of the exhaust filled the whole street and it worked. All warnings gone and it now drives so much smoother, thanks again.
Glad it helped
Where did you spray it through the air intake ?
This actually works. Cleaned a Peugeot boxer 2.2hdi this way yesterday. Slightly different process being as the air intake goes under and around the back of the engine. I just removed the air filter and poured it through that way. The sensor was not affected. After half a minute the street looked like a war zone as a cloud of smoke wafted away from the vehicle. Took it for a drive and the van was more responsive than it had ever been.
Impressive to see a vehicle with nearly 240,000 miles.
Thanks for this.
I'll do this with my Subaru outback, that has 113,000 and I'll do it with my Land Cruiser which only has 78,000.
Thanks for the video.
Was told to spray in after turbo and intercooler ( throttle body )to increase cleaning effect on agr and manifold
Thanks so much again Riley's Autos! I couldn't get hold of the Vetech product (in France), so bought a can of Wynn's DPF Cleaner WL23379 which i used in the same way as you show. I first checked with an OBD scanner that I had an EGR fault. I did, or rather my 2006 Mini One D 1.4 88hp did.
I followed your procedure to the letter, and felt really disappointed when I went on the test drive. Power was significantly down. The engine wouldn't rev above 3,000 under load. I assumed the EGR cleaner had dislodged some crap which then stuck in a pipe somewhere, so I tried all sorts to clear it to no avail.
*THEN* when I got back, I put the OBD scanner on again, no more EGR fault, but it told me that I had an air flow mass sensor fault. I cleared the fault using the scanner, and immediately the engine could rev to 5,000. Went on a second test drive, and the car drove better than it has in my ownership. Brilliant!
I'm writing this in case anyone else experiences the same problem after following your ace procedure.
My OBD scanner is a Creator C310+ which is designed for all BMWs including the Mini. It paid for itself in one go today.
You are removing the intake so the air flow sensor would record a fault so just clearing it will reset that 👍🏻
@@livingoncoinsyou do it after the MAF, not before. MAFs are very sensitive
A lot of vehicles wouldn’t start if you had the flexi pipe already taken off the MAF. The ECU wants to see a signal from the MAF before it starts. Trick is to have it connected loosely to get it started, then move it to one side for dosing.
TDI with a MAP sensor on the Intercooler. You don't need the MAF to run this engine.
Thanks 👍
Our new favourite fix... Done a dozen cars this week.
Fixed golf turbo underboost.
Also fixed BMW EGR Valve Stuck and loads more.
My praises to you.
Note. Some cars you need to repeat the process to get results from badly sooted vehicles
Thanks for watching
@@ORileysAutos great tip dude thanks so much. We been making nice profits doing this 👍🏻
@@vorsprungdieseltechnic9120 nice to know it's been helping you
Would this work on a golf gt tsi 1.4 petrol

Thanks for watching
Thank you very much 👍🏿. How you don't have more subscribers is beyond me
Thank you 😊
My TDI is filthy. She's old. EGR has been off for 1 year which helped but I didn't think about the PVC. I just rerouted it to keep my turbo and internals clean. I'll add a catchcan this afternoon if I can find a cheap one.
I stripped and cleaned my egr but not the intake manifold. I cleared the code and drove for a week. 250 miles. Light came back, scan tool gave the same code. I can't be dealing with taking all that out again to get to the intake. I'll be shoving a load of this cleaner through. Thanks for the video.
Same problem. Did it work?
Did it end up working? Did the code come again?
Hi, I know that this is old, but Did it work on your vehicle?
Bro had to come back to tell you this works so well. I used Wynn's 5L bottle. Parts shop said its almost same as vetech
Love your videos man your a life saver... £2500 turbo replacement on a range rover fixed for £25!!
Good to hear fella.
Did you spray it constantly without stopping
The Wynns says off car is that ok to use
I know this is an old comment, but could I ask, is the Wynn's "off car" 5 litre bottle okay to use like this?
Was it the Wynns "off car" stuff you used ?
@ORileysAutos My 2008 ml320 cdi Mercedes started going into a limp mode, that would reset itself after restarting the engine. Did a lot of research and came to conclusion by the OBD code reader that it may have a lot of carbon deposit on EGR valve. Decided to use your method and bought Lucas DPF cleaner. Removed the air intake, started the engine and started to spray the cleaner into the turbo throttle. After a few minutes noticed that the engine RPM started increasing, slowed down with the spray and waited for RPM to come down to about 2000 and continued spraying again. Did that couple of times and after a while of spraying noticed that the engine started revving again, stopped the spraying but the RPM started going wild, and I mean really wild. I jumped in the car puled the lever that was on the gas pedal and pulled the key out of ignition. Engine continued racing wild for a couple of seconds and finally quit with a Bang in the exhaust?!?!? I let it cool down, checked the OBD codes and there ware so many, managed to clear half of them and attempted to start the car. The engine turns but would not start??? What did I get myself into, is the engine hydro locked? Would appreciate any feedback.
Sounds like you used a flammable liquid and way too much so the engine has ran away
@@ORileysAutos, thanks for your reply. Wonder if you can tell me what's most likely possible damage. It's been run-away for about 30-40 seconds.
@@pandelko what happened did you destroy the turbo?
What was the outcome...?
indeed, I would avoid spray cans because of the flammable suspension gas. Safer way (if spray cans are your only option) is to first empty the spray can to a hand held sprayer like in the video and then use normal air as the pressure tool.
Mate just tried it and worked a treat 👍🏻
Were did you get the product from. Do you have a link thanks
Thanks for the feedback
@@wayneyoung1799 gsfcarparts.com
OK> So that tells me that particular DPF cleaner really does work. Another YT user did the same thing with a Wynns product and it made zero difference so he ended up cleaning it manually.
Great channel and best UA-cam mobile mechanic channel 👌🏻
Thank you 👍🏻
Another great video...like the way you keep it simple ,how much fluid would yo recommend spraying into the intake ?
I usually use 1 litre.
Is there a liquid molly equivalent which goes straight in the large pipe just like in the video?
That's awesome ! Would it be safe to do on a 2017 Transit Custom 2L ecoblue ? Or can you think of a reason why not to try it, just can't afford any engine damage 🙈
Hey mate, great video. Interested to know what the intake looks like before and after. Trying to clean the intake manifold on my SQ5. Had my EGR manually cleaned to fix the fault but want to do more for peace of mind. Didn't think it would work that well with the constant stream but.... Hey Presto! Nice work
We might do a comparison video soon
@@ORileysAutos did you end up doing a comparison video?
Did as per video completely stuffed my engine
Hi mate, i keep getting a EGR negative deviation too high fault, would you know what the means? Do i have a leak? Is intake clogged up
Would it be better to Remove the DPF before sending all this soot through that also and while its off can use that flush fluid to soak the DPf for 8 hours before replacing it rinse too and let dry then use a dpf fuel additive to restor metals after its clean.
Should have covered the MAF on the other opening looks like overspray could have got it. thanks i learnd somthin new.
If you read it sais it cleans everything including dpf filter so it doesn't need to be removed.
Just what I needed great video god bless
Your like the God of diesels
I wouldn't go as far to say that my friend lol
Where did all the soot and buildup go? Down the intake?
Out the exhaust broken down
Looks great! Do you have experience with the Transporter T6? They have a little EGR issue that can come up. Mine hase only 40.000km and the mechanic said it needs replacing... but if this works that wld be great.
Hi there,
Wondering if I can do this to my Renault Duster dci 110 PS motor. I recently cleaned all the sensors, replaced the Vaccum solenoid and fixed the plumbing. Its improved the performance and I feel the turbo VGT and exhaust manifold surely needs some cleaning cos' my EGR was totally choked through out.
Do you recommend this on a car that doesn't come with a DPF?
Great video! Thanks so much. Where can we buy the Vetech DPF Cleaner please?
Failing that, is it ok to use a fuel additive, but spray into the intake in the same way?
GSF car parts sell it. Or most places sell Wynn's brand DPF cleaning fluid
@@markmaddrell5106 don't use fuel additive or anything combustible 🔥
Hello this is a brilliant method to cleanout the EGR valve!
Will this DPF method damage a NON-DIESEL gasoline engine or can the DPF fluid only be used on a diesel engine?? Please let me know, I’m interested in cleaning out an old straight six 4.9 L F150 truck engine.
Please help- thank you & god bless you guys!
What could be great is to show the EGR valve from the inside to see the effect of the product, i would like to test myself as well.
Yes. This was a difficult part to reach but we may make a comparison video soon once we get a suitable vehicle to test
@@ORileysAutos I would like to see the result, i'll subscribe then
Hi, really like your clear video and am considering using this system on my Seat Leon 1.6tdi, as I`m noticing lack of power and heavier fuel consumption, can this method be used as a maintenance method, to clean the EGR and what about cleaning the DPF? Many thanks
Really enjoyed the video do use fluid on a when the engine is warmed up or from cold as I have heard horror stories about bent valves etc using products such as liquid moly and turbo rev?
What was the quantity of fluid you sprayed in the intake ? and did you spray it costantly till finished ? Looked at egr cleaners and they say use when engine is hot and spray in 1-2 sec burst, letting the engine idle for 3-4 mins every 10 sprays
Would like to know that, too...
Someone else asked this mate and he replied saying about 1 litre 👍
All cleaners are not the same. The one used in this video is water based afaik, and intended as a DPF cleaner. Specific EGR cleaners are most likely petroleum based, hence flammable. That's why you only spray in, in short busts, as it will get combusted in the cylinders, and make the Revs rise.....and could make a diesel engine "Run Away" for a short time....
Hi, I have Talisman 1.6 dci 130hp , you help me to solve problem with pressure sensor, thank you, may i do this on it same to clean ?
I have a 1994 dodge b250 cng 5.2 and not sure where 2 spray it threw since its different set up than this van and also have a 2007 prius will it be fine to do in my prius threw the same way you did it spray it threw the air filter hose or is it somewhere else
Hi Jimmy, my v6 tdi vw touareg has a single P0234 turbo overboost code meaning there is lots of carbon build up on the wastegate and vanes, can this method unclog the stuck parts on my turbo? My concern is turbos do need engine oil to lubricate the turbines, spraying that water based DPF cleaner directly into the turbine will not impede the performance of the turbo?
Wow very good information again
Thanks for watching
Hi, my misses has a suzuki swift 1.3ddis which ive not noticed any smoke come out on a good run which it used to do. It ticks over abit rough, when cold tick over is erratic and it STINKS from the exhaust.
Is this a sign that the egr valve is clogged. Tia Karl
Do you know if this would work with a Range Rover Evoque 2012 or a Ford Transit 2010?
Got peugeot 308sw bluehdi 2.0 l (2014) just got dpf washed on mechanic they change oils too but service light and engine light still burning. Car is on limpmode. Any advice should i try to clean it in this method too or is that even possible to my car?
Wait how does it go to the egr if your spraying the intake
The egr the pipes use air comin frpm the exhaust
Could i use any other dpf cleaner? Im in germany and i cannot find these two products.
Just watched your vid and our citroen relay van has the same p0401 code and is saying the erg signal is low. Yours is saying Insufficient flow. Are these two descriptions indicating the same problem as yours as we have no light come on.
I just wondered if it has any cleaning effect on the DPF doing it this way
Is this method works on the 205 benz 651 engine AMG
My Galaxy 2.0 TDCI puts the ESP light on under boost in higher gears ( code P0238), so think i'll give this cleaner a go, as my car problem could be clogged vanes/acuator.
My EGR valve is blanked, so is it still ok to use this cleaner?
How did you get on?
please may I ask what model of Autel scanner you are using? Thanks
Hello. I followed the procedure with the jlm for cleaner in my Chevy Cruze. After 5 mins drive on the highway the oil light came up and the power was cut down a couple of times.
Then I did a dpf regen with the autel tool and drove it back in 2000 rpm didn’t make any issue.
Is it normal?? Should I be worried about the oil light?
The main thing is I drive about 150kms everyday. And this weekend I’m going on a road trip to france and Belgium! Almost 2500kms!
I've not seen an oil light appear. Did you check level
The 1.5 nissan Juke and qashqai suffer from blocked exhaust pressure pipe/sensor which usually throws a Eml and Traction light up until the pipe is unblocked do you think this would work ?
If you open one end of the pipe and pump the fluid through I'd say it's very likely to unblock it
egr valve is usually only open at idle
Hi where is the best place to spray this on a qashqai 2.0 dci j10 m9r engine? Will it help get rid of a P0488 egr pressure sensor code? Thanks
Hello. Do you have a before and after video of this. Thank you
Can I do this on a sprinter van and will it damage engine like combustion or anything
Dya think this method will help free a sticking acctuator/turbo on a Nissan 1.5 dci?
Yes if it's sticking from soot internally. The rod can seize externally on some vehicles from dirt and corrosion
Does this work if the car is in limp mode to clear the soot? Then afterwards go and get then engine light cleared.
Hi, I have a 2014 ford kuga 2.0 tdci with 16,000 Miles on and had a new dpf last year, this is now smoking on hard acceleration where it's very visible from the rear window. All filters changed and no signs of boost leaks.
It's also has an rpm bouncing when coming to a stop (idle to 1400 a few times then settles )
Would this method help cure this problem? Thanks.
Would the Lucas Diesel Deep Clean DPF cleaner work instead of the VTECH?
I'm not familiar with it
I’ve looked on eBay for this product , it only shows the off cleaning product , can somebody please be kind enough to provide a link so I purchase the correct one. I’ve been watching your channel for ages , if you were my area (London ) it would stop these jerks charging a fortune and bluffing it.
Hi can this method be used on a 2.0 Hdiblue Peugeot boxer 2017??? Great videos.
I have 2008 Passat TDI 140BHP Highline Model saloon,
Can I use this product same code on my car ?
Just had New clutch fly wheel pressure plate & watter pump & timing belt kit ?
157k is on the clock & using Shell V-Power Diesel last 57k, exhaust pipe is clean as clear no carbon when I place my finger in, so this helath of my engine,please advise me ove on it can I use the product Vetech DPF cleaner and do I have to use whole 5 Ltr ?
Wow nice job.goodluck.
Thanks for watching
Awesome video thank you, will this work for a 2014 Mitsubishi Triton Turbo Diesel.
Any vehicle mate all the same principle
Yes 👍🏻
i did this bur a strip of duct tape got sucked in am i in trouble
Hi , i have an Audi A6 and today it shows an engine sign on dashboard , when diagnosed with tool it shows an error ( turbo /super charger underboost ) , so i don’t know that can i use this method to solve the problem ,,
Same problem with Skoda, how did you solve/repair it?
Will this method work on the VNT mechanism.
I’m not sure if my van has an egr or vnt problem.
I just tried Liqui moly intake cleaner and this helped nicely, but the problem is still there.
Thanks
It should work
Hi would engine carbon cleaner also work?
Will this work on any car with a egr and sooted up intake. Would it not block the dpf.
Won’t this fluid harm the turbo and might also end up in the combustion chambers ?
In what way will a water based cleaner harm the turbo?
What’s the issue with it entering the combustion chamber? It’s no different to water/meth injection all be it without the methanol. The high temps of the diesel combustion cycle will vaporise the fluid. As long as you don’t throw the whole 5 litres in within 30 seconds and hydrolock the engine there no harm to be done. I mean the fact it’s been done on this van every 50-60000 miles and the van is on nearly 230000 miles tells you everything you need to know.
@@Mac_F87 just thought the carbon in the EGR valves and air pipe might end up in the chambres and harm the cylinder walls, or the turbine!?
@@anesdj4282 the EGR feeds in between the anti shudder valve and intake manifold. When you see the amount carbon and oil sludge in an EGR valve I’m sure carbon and oil sludge debris ends up in the cylinders quite often. Any of that that ends up in the cylinder will surely be burnt in the combustion process since it’s hotter than in a petrol engine. There is probably very little in the way of large debris that reaches the turbine in the exhaust side of the turbo.
Hi! Can we do the same on petrol cars?I have a bmw 320i. Thank you 🙏
Could you set the revs using the Autel instead of pushing the pedal?
EGR fault on my Peugeot 207 1.6 HDI, I'm no mechanic and I'm looking at Wynns EGR cleaner, does this really work or should I use DPF cleaner like your using please ???
i try this mine dont work turbo get stuck again, need to remove exaust side and spray in there
Has this fixed those particular codes from coming back since this video was made? I have the same codes and i'm interested to try this. I ask because if i clear the codes, I may not have them return for a few days sometimes.
Codes did return after 6 months so I do e another clean
Hello, I really like the video, I own a Citroen grand Picasso 2010 1.6 hdi and it looks I have problem with the egr valve. I think I should use that fluid, I have 2 questions: should I spray right in the turbo as it is the most easy for me to reach? and when I'll finish the spraying, can I reset the codes with my OBD Car Scanner diagnostic tool ( is an app I have in my android phone connected with a bluetooth OBD device) or should I do that with a better and more professional diagnostic tool? Thanks
Did you ever do this? I've bought some of this stuff to do a friend's Berlingo but not got round to it yet.
@@1000sofusernames
Yes I did the procedure twice, lots of smoke come out and the car drives better but the egr valve still has issues as it shows on my OBD reader. The second time I think that ruined the AMF sensor and I had to replace it because I was reading intake air temperature about -20C!
Do you have to do an oil change after doing this? Where is all that cleaned carbon gone? Is it in the engine oil circulating in the engine?
It goes down the exhaust. How much gets stuck in the DPF I dont know but it is meant to be DPF cleaner.
Would you say dpf cleaner is just the same as using Revive cleaner?
I know this is a daft question, but could I ask, is the Wynn's "off car dpf cleaner" 5 litre bottle okay to use like this?
I'm wondering the same thing - did you find out ?
@@MrR6pilot I never found out matey, sorry. I think it would be okay, but I've never tried it!
Hi,tried your methed.Light was off for about 24hrs before coming back on.Repeat the process?3ltrs left.
Going to try this on my 2.0 vivaro. how many litres did you spray through on this video? was it 2l bottle once?
Yes 2 litres
Did this yesterday, after trying to resolve an issue with van not getting over 3000rpm, there was an egr fault before i had the egr mapped out. But suspecting EGR is blocked. After doing this initially, van drove spot on for about 5 miles, then suddenly went back to not revving over 3000 rpm. is it worth doign this again, maybe a couple of times to give a good clean through? no other fault codes on my van and egr fault doesnt appear any more since it was mapped out
I can’t seem to find any supplier in the USA. Motor Power sells a similar product here. Would the Motor Power brand also work? Or, is there another online seller besides GSF?
@ORileysAutos
Will this work on a Mercedes Sprinter 316cdi 2011 OM651 4 cylinder 2.1? Just like that? Straight into the mass airflow like in the video?
Spray AFTER mass airflow sensor!
Is this car with DPF? Will this damage exhaust converter or dpf ? Thanks
Did this today and had the Check Anti-pollution system "Warning light" come on after I sprayed 1 liter of the Wynns in the air intake hose, took it for a 20 mile @ 3500rpm to try and clear it but still have the message?

doing this metod can possibly clog up the DPF? an after that maybe need an regeneration??im considering try using this metod to clear intake and EGR valve on my Opel (vauxhaul) 2012 Corsa D 1.3cdti 70KW, before try to dismatle the itake manifold, because this engines (1.3mjet fiat base engine) tends clog up, any advise or any experice, O'RilleysAuto, thanks...
I have an opel corsa 1.3 cdti 70kw

Anyone know if the Protec dpf flushing fluid works with this method?
Any success on a Range Rover td6 with this method ?
Hi, thank you for this video. I have a similar problem on my car, it's a diesel Nissan Micra 1.5dci k9k engine. Suddenly I started to have slightly lower performance from the engine and slightly worst fuel economy, check engine light came on but other than that the car run fine (starts with no problem, no smoke from tailpipe, no strange noise). Hooking up a scan tool resulted in the code P049B, which refers to insufficient flow in the low pressure EGR. You think it's possible to clean the valve with this method? Thank you for any advice.
Yes I'd try this method
I've got the same car and problem, garage quoted 7 hours labour at £280 to remove and recommended a replacement egr. Have you tried this yet?
@@mooseyman74 hello. Sorry but no, i didn't try it yet. I went to my mechanic and he told me that the cause of the problem probably is a wire mesh gasket placed after EGR intercooler that is clogged. I'm better of with changing instead of cleaning it. I'll go back next week to see how much it will cost but if it's too much I'll try the method of the video.

That's what I'm thinking of doing
@@nometalgearr did you try cleaning the egr through the exhaust retun pipe
@@lees7890 I just ended up cleaning the egr while the manifolds were off. Egr was pretty clean and didn't need much tbh
Is it advised to change the oil after doing this also if my dpf is a bit clogged will I be best cleaning the dpf first or will this clean it all?
Best to clean the DPF afterwards
So follow the sequence, clean MAF, EGR, then DPF, then Oil change if possible
How much you sprayed inside and for how long?is any fault code or symptoms?
Did you mix the DPF Fluid/Flushing fluid with water? And what spray bottle did you use?
Don't use water. I just used it with some seafoam and drove it like I stole it.
hi, i have just bought a 2010 polo 1.2 Tdi on 114,000 miles and its got a full service history including an egr change 3 years ago and about 10,000 miles ago. it drove perfect at first and i was just switching the engine light off but now the glow plug light is flashing and the car is in limp mode. i am getting engine code p046c on my generic machine egr circuit. One mechanic said it could be a blocked DPF another said blocked egr. what could be the cause of this before i splash out on cleaners or a new valve. cheers!
It will likely be both in my experience.. But, do it all snd its done, clean air filter and clean MAF sensor, then EGR, then DpF… and then oil change due to most of soot contaminating your oil. i think its very likely to be both, but, consult a reliable profesional mechanic if you do not want to tackle it yourself
Hi my car has dual air systems, do I spray both intakes?
Yes
thank you
👍🏻
Does this affect the catalyst? Any substance used must be catalyst compatible or it will block the catalytic action.
Yes this is safe to use on catalyst vehicles
