Repetitive DPF Faults After 3 Regens At Renault??
ฝัง
- เผยแพร่เมื่อ 15 พ.ย. 2024
- Here I highlight why a diesel particulate filter regen doesn't fix the issue with a blocked DPF unless you have fixed the cause if the blockage that is usually caused by another fault in the engine.
Customer was quoted for a replacement DPF after the regens were only successful for a few days. A new DPF would have been a waste of money as it would have blocked almost immediately. Main Renault dealer quoted over £4,000 for replacement.
These vans are badges under many different names..
Vauxhall Vivaro.
Fiat Talento
Nissan Primastar
Nissan NV300

It’s very refreshing to see a guy who has genuine integrity.
100%. He’s the guy.
Engines where you cant see or access anything is one of the main reasons I rarely work on vehicles much these days.
As for the main agents they are often very poorly trained and at best just swap parts. When I trained back in the early 80s you had to understand everything in depth and to learn diagnostics properly.
Main dealers.. trying to fleece customers.. whats New!!! Top mechanic and top work jimmy. Thanks for your education.
Glad to help
Totally agree with you, but equally, Renault would happily take 4.5k off that customer, and send it out the door with the same fault to come back probably in less than a month, it's not good enough! No one should know a vehicle better than the manufacturer, but it's just not the case! Great work as always, I fixed my own following your advice, and I've just passed 10k miles without an issue! Keep up the amazing work! Cheers
Jimmy really is, a HERO!! ANOTHER coffee, coming your way, Jimmy!!!
They're "Parts Chuckers" not "Technicians"
or parts not put on,but its part of a service.
O'Rileys Autos fixed it again!
you're an honest & professional mechanic - not many of you about these days! and the comment about focus on a specific job and be a master is true in many other trades!
I work on diggers .plant etc .trucks but because of you ive cleaned van and jeep dpf etc and sorted stuff like that.brilliant info.
hi. im in germany and no one seems to know about these fixes. ive watched about 18 of your vids because i have the same issues with my vivaro.
last guy wanted to replace my cylinder rings for 4000 euro.
i skipped them immediately. now its at an Opel dealership and i made them well aware of your videos and fixes. NOW they are telling me i need a new turbo cuz thats where an oil leak is. or so they claim.
i will be very upset if they did not try the 2 suggested fixes. and i def will check those myself now that ive bought the tools.
thank you for sharing these videos.
Get them to take a picture of a low point in the turbo to intercooler piping / hose, if the inside of the pipe is more than just wet with oil then you have a turbo oil leak. Essentially you know how often you top up your oil, so you must think if its not under the vehicle then it must be consumed, not good for the DPF. However if you have never topped up the oil on a regular basis because its ok then you are fine.
@@tomcurran65 its weird. My vivaro Def consumes a ton of oil. About 1.5L per 1000km. BUT no smoke anywhere and never any spots on the ground anywhere either.
The dpf was indeed full but i cleaned it back in january and recent tests show that the dpf is still fine.
@@AshisogiTenno yeah that's way too much oil consumption, the burning of it is being leaned out by the ECU, essentially your diesel consumption has improved because your injectors don't have to supply as much. It's a small amount but it's happening. The emissions sensors on the exhaust will detect too much smoke for the air supplied and turn down the injectors. If you can pull off the hoses to the intercooler and shine a light in, if it's glistening with oil then you know where it is and you need a turbo
@@tomcurran65 you wouldnt have a picture or video of that which i could look at for refrence? i build houses but with motors im a novice
@@AshisogiTenno I don't have a picture, but it sounds like the Opel garage are telling the truth, especially if your oil consumption is that high, go back to them and get them to show you the intercooler piping and check for oil, and then the turbo impeller shaft, if you can feel x and y movement in the shaft, it's probably ok, however if you can feel And see the moment then it's not. If this is the case then a new turbo is required before any other work is done. I do have a picture of oil in a Volvo intercooler pipe... how would I share that image with you?
i am a tech up in Scotland and u have helped me out with some faster diags on the dpf faults and u are my goto when i hit those faults good on ya man
No nonsense straight talking , thanks for sharing Jimmy your a top bloke for helping people out who don’t have funds for expensive garage fixes
The wonders of CAD - you have very experienced software engineers trying to cram everything into the tightest spaces, without having a clue of how an engine works or what's required to do maintenance or repair - just fill the tight spots and save as much piping, wiring, etc., in the process. Remember, cars are now seen as disposable, not repairable.
Great job, Jimmy, reaching the desired result, despite all the obstacles placed by the manufacturer.
Great job again, dealers don't have procedures or the kit for Cleaning DPF's. just regens or replace. They especially wouldn't have gathered the info on the Launch fluid versus other fluids. saying that though, they should know about the role of the glow plugs for normal regen, and even if they didn't, they should have swapped them out, they had a fault code for them.
That’s the main issue. Dealerships have to follow the manufacturer repair process. Which is unfortunately usually see X symptoms replace Y part.
@@Mac_F87 yeah, they treat dpfs as a black box, replace if faulty. Jimmy's work has shown an amazing success rate and his process is really refined, imagine what he could do if he had his own garage, there would be a que down the street, he would need traffic management 😊
Jimmy please keep making videos . Even for sane stuff u made before. Trust me we dont get bored watching. Infect i am edicted to watch your videos.
Jimmy you never really run anyone down , I can clearly see your demeanour & that is to help others aware as you state regarding DPF troubles , & like your good self Sir , I too certainly do not know everything, even after 36 years as a DIYer , but having a decent scan tool does of course help us to diagnose roughly what is wrong & lead us in the right direction . Again what a stupid design of an engine set up for access 👎but another great video “once again” buddy 🤙👍🏆😎
Enjoyed this one Jimmy!
There's something very satisfying for us DIYers to watch a professional suffer the frustrations we go through what you'd call simple jobs!
Go on jimmy, top man . Absolutely right in what you're saying. Forced regens just a quick easy fix for a problem thats not addressed properly.
Spot on video I agree with everything you say well done.😊
Glad you think so!
Finally a video where you check a pipe with working DPF ! I was starting to think all pipes have soot in them...
I'm not a mechanic and had a Dpf problem with the work van a few years ago which made me interested in knowing how to solve dpf issues. I have invested a considerable amount of time watching your videos and have learnt lots along the way... Now if only other actual mechanics can invest their time in learning for what they actually charge the customer wouldnt that be nice and professional
good points at the end, main dealers mostly employ "fitters" not mechanics, plug in the machine, it says dpf blocked, fit a new one. love your videos and your methodical approach to the diagnosis. as others have commented its nice to see someone genuine in the trade
Another great video Jimmy 👍🏼 I’m retired from the motor trade but still watching how the industry is changing.. not for the better I might say.. I watch videos from pine hollow auto diagnostics and he.. Ivan ..is like your self an honest guy .. my point is that he puts up at the end of his videos a follow up of his repairs to show that his diagnosis and repair was correct and vehicle is fixed… just a thought… keep up the good work buddy 👍🏼
I’ve got one in bits at the minute, timing cover leaking no room at all. When I do a dpf clean I remove the intake pipe and put the fluid in through the upstream nox sensor hole. They have low pressure egr valve bolted to the back of the dpf so you are supposed to disconnect the maf sensor to stop the valve from opening .
Another good O'Reilly's video. What was the problem, Glow plugs, DPF Pressure Sensor, or both?
Another honest video ❤
You one of the good guys if people are bothered by what you say it's because they have been found out talking and doing BS to other people, they should count themselves lucky they are not named personally.
Great job, thanks for uploading. 👍
Glad you enjoyed it
Another job done one more happy customer
Keep on teaching use jimmy
Thanks 👍
I love these videos.
The glow plugs looked different to me. 2 were black and sooted up and 2 were brown. I would say the black ones are not working properly as they are not burning carbon off.
As for running other people down, some people deserve it, this is how evil is defeated. If it was a general mechanic that was looking at it previously then I agree with cutting them some slack. As it was a main dealer with mechanics that have been on specialised courses then definitely not. They are either incompetent or robbing a-holes.
I've recently learned that the DPF is almost always the symptom, not the issue.
💯
I wish you operated up in North Yorkshire Jimmy!!! Is there a Launch product that you would recommend as a preventative measure for a 2016 VW Transporter? I always use Shell Vpower and Millers but is there a good pour in the tank product for DPF and fuel system cleaning? BTW, I've checked my tail pipe and it's clean.
Cheers mate.
Dave
I own a dacia duster.. Renault engine. Dpf sensor is in same location and an absolute bugger to get to. With very tight metal clips. I thought it was ridiculous to get to untill i saw this and realised realised mine is a dream to get to in comparison
Jimmy, you've clearly found your niche with DPFs. I would consider you to be the DPF guru. You're not running the dealer down. You are highlightiing the fact that they're quoting for unnecessary work.
But you're quite right if it's been there it they've clearly misdiagnosed it so this costs the customer potentially a lot.
Well said jimmy
Another top job Jimmy!
Cheers
Great work jimmy you are a specialist 👍🇮🇪
I try
Champion Jimmy! Well done
Thank you
Jimmy did you ever try the dpf cleaner from liquimoly ?
Any good or would you still say launch was better
Although I have no interest in having an EV, it’s this sort of thing which will push more people to think and possibly go that way. I wonder if that’s what’s really going on. With future increase of emission controls on vehicles, this is only going to get worse. The only other way maybe is to buy cheap, keep for a year and get rid of. Or if you can get it, is an old classic people can work on?🙁
Great job Jimmy 👍
Cheers 👍🏻👍🏻
Top job Jimmy
Unfortunately dealers don't have the option of saying no to any job
Right angle pick-tool poked into the clip & twisted opens them. Old-skool carpenters pliers closes them. I cut half the length of the handles off my carpenters pliers so they fit into more stupid manufacturers places - you don't need much leverage to get the clips shut. It works, which is all I care about.
On the chemicals front, Wurth do an aerosol DPF cleaner that is (like most Wurth stuff) good. Being an aerosol removes the need for a compressor, blah blah. I dislike the cost of most Wurth stuff, but once the cost is forgotten, the quality remains. Wurth & 3M always make me wince at the till but smile when using their gear.
I do lol at the "Green" logic of DPF's - the Greens whinge about emissions, which floods the world with plastic ad-blue cans, pours emissions out during dpf regens & cleaning - plus is crap.
Surely they would have scanned it and seen the fault suggesting the Glow plugs were faulty and then surely there test plan would tell them these are required to carry out a successful regeneration. I am amazed at incompetence at main dealers having dealt with them only once and that was enough.
Trouble is some people in the workshop just don’t want to get involved with this sort of job 2 blokes in the workshop I’m in just clear codes and send customers on their way low and behold 1 week later the light is back on but this time it’s passed to me when it comes back. They just want to do services all day long
Hello! I saw it is out of stock, is there anywhere you can buy the cleaner? Thank you!
Class act jimmy
You are a genius.
Any idea what is the lifespan for Dpf if all is as supposed to be ?
How many miles?
No add blue .
With add blue normally 120k and expensive problems starts.
I agree with you, that Vivaro has a terrible engine bay layout. Sometimes I wonder if these companies make all their old engineers redundant, then get some untrained and inexperienced guys to design their next model?
Did u guy know that if you double click a comment. You like it . If you triple click it you reply 😂😂 i only found out
Didn't know that! Thanks :-)
Oh yeah
That’s magic
@@eoghanhennessy443 just tried it.....that's voodoo!!
Thanks
Schumacher !!!
Also , soot never goes down to 0 after force regeneration .
It goes down to 7 or 8 .
Unless they have changed it in new vehicles.
Not long and people will go to shaman to fix the car 😂
Another winner 🙄. Designed by the “ after a ‘good’ ( liquid) lunch “ club @Renault? 😖 you really DO earn your money - hats off to Jim 😉
Thank you!
Got a question do the Renaults need to have a certain amount of diesel to regen?
Yes. Diesel is used in the process. Can't recall if it stops with the warning light or below quarter 😐
SUBSTANTIAL
Great info cheers .
No problem 👍
Just to add vauxhall didn't use that late m9r engine! They changed to peugeot vans at this age.
Yes I know
so what was the initial cause of the problem ?, was it because the heater plugs failed meant it wouldnt do a regen thus blocking the filter.?
Yes
Top man 👍🏻
Thanks! 😀
👍👍 Yet another great video.
Thanks again!
Often no point in replacing a part until you have fixed the cause of that part failing. If you do the new part will probably fail too.
Glow plugs used heat up exhaust to clear DPF causing them to be burned out earlier. There is an error code saying they are shot are they blind.
Jimmy would the oil service spanner light not stop it from doing its cleaning?
If it's for oil dilution yes. Normal service i dont think it does
I own a Vito with a Renault engine. 109 CDI. I believe the service light stops regeneration. I've had my dpf clog up twice when I've ignored my service light. Wasn't convenient to service so let time pass. Didn't take long before I got message to take for a drive with high revs.even doing that without resetting service didn't resolve. Reset service and took for a good run staying in fourth gear solved. Point being a service light can stop regeneration
Cost me bucks initially. Plus when a Vito new shape regens. The revs sit higher at 1000 rather than the usual idle that is just under. I let it complete until revs drop then turn off
cheers Jimmy , the new vans are sh## to work on ... thanks design engineers !!!!
Yes they are!
Heap of scrap 😂trying doing time chain on one them vans 😅
If there taking the money to get the work when they don't know how to do it, they should be slagged off.
All valves and sensors should be all made accessible by manufacturer from now on .its a joke nowadays
May the Lord Jesus bless you and keep you in His truth.Truth needs to be said, you don't point at the porson but at their bad jobs, because when you pay labor person who do the labor must stand behind it and give guarantee.
If there is heater plug issue it shouldnt carry out full regen as it uses cycling of heater plugs as part of regen process dealer should know that
What a ball ache they reallly dont want you fixing these things do they
Their not really mechanics these days. they cant sort anything out by looking etc.
New van 73000 new glow plugs what a pile of shit
I’m a window cleaner, but Ive followed you for a long time and feel I now have a good knowledge of DPF systems !
So surely why are main dealers failing customers?
Renault for years dont really make any profit on their cars thats why they are so much cheaper than competition. They make their money on parts.
Like buying a home printer, but a lot dearer !
✊✊✊
Who tf engineers these newer cars. Wtf is it with the size of that massive intake pipe across the whole engine!
Manufacturers no longer have hands-on engineers on staff. Instead earnest young graduates (who often detest the ICE with a vengeance) follow the Latest AI programed and this is the result. None of these sensors should require a strip-down to access. I am reminded of the Renault 4 bulkhead mod in the 1970's to access the timing chain. Cut a big hole in the bulkhead and plate it up.....nb: don't tell Renault 😮
DPF can be removed and cleaned properly. This is first aid.
Too much labour involved on these vans to justify removing it just for a clean
Removing dpf just for cleaning soot doesn't make sense, imo. Jimmy proved so many times that you don't have to do that. Removing dpf is must to when you are trying to remove ash. If you are removing soot you can do it on the car. Can you show us videos where much better results are achieved with removing dpf instead on car cleaning, assuming we are talking about soot removal?
Typical French, everything in the engine bay looks like an after thought of what to put where, and yes that's pretty typical of main dealers these days techies not having a clue as most them only know how to service vehicles, that's if you can call it serviced, it's nothing like we used to do back in the last century, services these days aren't nothing more than an observation checkover at the same time costing a fortune!! 👎🤬🤬🤬🤬
