- P244C Ford Transit Common Fault.
vaporizer blocked causing the dpf not to reach a high enough temperature for regeneration
My bro has a ford Smax and it was one of your videos that popped up during a google search, i pulled out the vapouriser and cleaned it out with some brake cleaner and compressed air and re fitted it, that was 6 months ago and its still working. Thanks for the videos and the info keep them coming, cheers
Glad I could help
Same here, that vaporizer is 99% the culprit of that particular ‚DPF temp too low‘ issue
Nice one Jimmy it's freighting to see in this day and age considering how long EGR/AD BLUE and DPF'S have been around now and garages still can't fix them .
exactly they don't know how to Fix them they are morons.
So, I have an issue with DPF. codes p246c p244c p246b p2463. I connected the software, and the DPF pressure seems all right. The sot accumulation is 225% and 217%. The exhaust gas sensors 1 and 2 show 100C and don't move at all, and the voltage does not change when revving the engine, either. My theory is that DPF is not blocked; faulty sensors prevent auto regen. What do you think?
Nice one Jimmy , another job sorted , i did the wire trick on a 2018 vivaro yesterday , it was blocked solid the metal pipe on the pressure sensor from the dpf , cheers for your continued tips and information, we in the job all need info from time to time , you cant beat it when someone has experienced the same fault as a job in the garage before , so many guessers nowadays in every job
Good to hear
Hi, I got a 2018 Vauxhall Vivaro, for my son, a few days' ago. I'm going through what I can change, to make the van run smoothly. What is this wire 'trick' you did? I cannot see this on the video, can you tell more? Thanks!
@@tomsurrey2252 if you take the dpf upstream pressure sensor off ( on the left of the engine ) at the back ,take the rubber elbow off and check the metal pipe is not blocked if so use a thin wire bowden cable , similar to a bicycle cable and use a drill on slow speed and drill it out , keeping the cable tight or it will wind itself up it took me over an hour to do the one I was on , it then should allow the cable to push straight into the dpf , I then ran the engine just with the sensor plugged in to feel gas flow when the engine was running , then put it all back together
@@tomsurrey2252 I have vivaro videos on the channel
Great video Jimmy, I've lost count of how many of vaporisers I've watch you change - but they are so interesting. Keep up the good work 👍
Are some of these garages/workshops just smoking drugs all day and or watching porn on there computers cause I'm pretty certain that if you were stumped on any of these DPF issues a Google search is probably going to lead you here.
I think you were previously correct about glow plugs being needed for euro 4 German diesels witch don't have vaporiser but use fuel injectors to to inject on exhaust stroke to clean DPF filter ,Glow plugs are used to raise temp of engine and cylinders whilst cleaning / any intermittent or faulty glow plug will cause regen or forced regen to fail on VW euro 4
Seems to me some of these mechanics need to be retrained.
Your bang on right there jimmy, as soon as I saw the symptom on this video I thought blocked vapouriser. I can’t believe Garages are not able to understand the basics of these systems and then proceed to go on a fishing trip hoping they’ll fix it. Customers need to start claiming their costs back from these places, it seems rife throughout the trade. Thanks for the vids, always interesting.
Wish there was a Jimmy in every town! 👍🏻
People believed that the design of the exhaust system for all diesel cars were the same that's why. Now after watching this video i am convinced that i had a problem with the vaporizer because all the symptoms were the same even the fault codes.
i'm not a mechanic, i just enjoy the knowledge and the knowhow. it's good to see you getting more and more comfortable on camera.
Good video jimmy!
I worked in a garage 51 years.. Most technicians haven't a clue, that includes even me.Thank F I'm retired now.
i for one is not surprised by this state of affairs most ( mechanics ) are just super fitters and no real engineering skills sad really the none mechanical are in the land of the stupid ((sorry) but it is the truth
Nice one Jimmy, you are spot on the possible cause with sound logic, you win half the battle with understanding the mechanics of how it's gone wrong before you do the repair, thanks for another valuable knowledge piece.
You should keep glow plug activity up on show when doing the next regeneration (I’m saying there shut down on regeneration)😅
its obvious these mechanics dont watch your videos. Another great job jimmy and nice hat. Hats of to you
All this trouble the user has to endure van off the road. Just get an old van and look after it
How are these garages getting away with being so inept??
He should take them to court if they don't give his money back!
The moment I see him plug the launch dpf cleaner. I feel dirty and have to stop watching. Another tool
Jimmy absolutely spot on, I'm not a mechanic but when you said Ford Transit..... I said vaporiser 😢
Well done Jimmy. Saving the planet one van at a time.
Another great video with easy to understand instructions and the thought behind the instruction
I agree, too many 'mechanics' swapping parts just on spec without research into the logic behind the fault. Great video and very honest and informative, thank you!
that engine coolant temperature on the test drive seemed way too low.
never got to 80c. they might've put in a cold thermostat at the shop and that might cause problems in the future.
It did reach 84 off camera
Knowledge is power and you are a very powerful man jim ❤
great video as usual , but with these latest vehicles with DPF filters whats the best way to keep the DPF in good order , i have a new focus 1.5 ecoblue one every 6 weeks or so i add DPF cleaner when i fill up good idea or waste of money
I've ran ford diesels for years, biggest issue I found was supermarket fuel, caused engine management lights etc, but run the same car on branded fuel, there was no issues, i did some research and although supermarket is the same base fuel, supermarkets don't put the addatives in that the likes of bp and shell do, this causes them to run dirty, and produce more soot.....I now constantly run my own cars on bp/shell and have never had any issues, and never had to use dpf cleaner and some of my diesels ive run up to close to 200k, I've recently purchased a 2015 volvo v40 d4, for my wife, as her focus was stolen, the volvo is only on 115k, and since just after we bought it, its been suffering with constant engine management lights, the inlet manifold and egr valve are caked in soot, ive stripped it all to clean it out ad best i can...its now running premium diesel and its not had any further issues...hopefully I've saved the egr before having to replace.
Always a great video with detailed instructions, Thanks!!
Great videos I've learned loads thanks. I watched the one where you were left holding the key of a car and the guy had been told the engine was finished and you hadn't got paid. I use the SumUp payments system, You text a payment link and when payments received you start work.
Another great educational video Jimmy 👍, I also wanted to ask if there would be any chance of you doing a short video using forscan diagnostic to let us know what you're thoughts are on it and if it's worth paying for ? Cheers Jimbob.
Jimmy can you come to london for a mk8 transit
Always wondered how DPF get to such high temps.
What does too high mean mate i had message pop up two weeks ago on my Mondeo after a oil and filter change hasn't come back since, I also get turbo boost too low sometimes switch it back on and off again it's fine. Turbo fine pipes all fine. Any ideas you are a genius
too high of what?
@@JustMe-Dude exhaust temp too high for regeneration
The dpf could be really really blocked and this might cause the high temperature warning. The low boost issue might be a symptom of a blocked dpf as if the exhaust gases are having trouble getting out then it can't spool the turbo up properly.
If there was a fault in cooling fan circuit it wouldn’t regenerate, so maybe that was the reason, however of course he should have checked the vaporiser
Customer said it was the repeated dpf temperature code that was the only fault
Jimmy, I love your videos but I'm now stuck with my diagnosis. I have a Jaguar F-Pace 3.0D V6, 2016. 1 year ago I had a cracked DPF core and it was renewed. After that after some driving the oil level has risen from middle to max and service interval went from 25.600km to just around 3.000km. Then I changed the oil, bought OBD-2 scanner and now after few months of constantly looking at parameters I figured why it happened. Active DPF regeneration happens every 80-150km on mixed driving style and maximum 300km when driving only on highway. Way too often!! I successfuly completed every active regeneration for 4 months and there is no more oil dillution. DPF pressure sensor looks ok. 0mBar after regeneration on parked car and 10mBar when it needs regeneration soon. At 130km/h it's 30mBar after regeneration and 120mBar just before the regeneration. Sensor looks fine, DPF seems to clean itself quite ok. But it fills up too quicky!! I have to be careful every 3 days to succesfully complete the regeneration process. On active regeneration, the DPF reaches up to 670°C. On city driving it's around 220°C and on highway on passive regeneration it's about 350°C. The DPF company that renewed the DPF said it's been renewed correctly and it should have normal "capacity". What can I check to diagnose this problem? Why is the DPF filter getting full too fast? Could it be one of the EGR valves not working correctly maybe? I've seen very big and constant errors on EGR (A) on my OBD-scanner. EGR (B) seems fine. Could it be that EGR (A) is causing too much soot to collect on DPF? What else could I possibly try? I wish i lived close to you. You are amazing and I hope you could tell me what is most likely the cause. I would be forever gratefull for your help.
From what i feel, is a lot of garages now have this habit of ‘maybe its this, customer pays, then well maybe its this’ they are glorified parts changers with little knowledge on certain aspects of the job.
Great job Jimmy 👍
I have a question Jimmy, when you put the dpf cleaning fluid in, is the dpf cold or at operating temperature ? I hope this isn’t a stupid question but it’s something I’ve not heard you say before.
Most of these cars have showed up less than a minute before recording so they are at operating temperature but not regeneration temperature that would maybe damage it
Fantastic question fella....
Hi, my catalytic temperature bank 1 and 2 are blocked at 578.5 degrés, and the one after fap at 1000 degrés, éven if the van is cold, an idea ? 😢
Hello, nice clarification, thank you! I've been having problems with my DPF in the MB 200 CDI, W204 for a long time. Question, which diagnostic device do you use and from what price range can you use it to measure the DPF temperature? I have one that obviously can't do it. With my ArtiDag 800 from Topdon I can only observe the regeneration itself, read out the ash content and the soot content, as well as a few other parameters, but not the exhaust gas temperature in front of, in and behind the DPF/cat. I suspect that the required temperature is not reached.
Thank you and kind regards from Germany.
Great work Jimmy, what happens if you replace the vaporiser and don't reset the values, will the van not realise you have the new part installed and still give the fault code?
Hi, I need some help. I have a Renault Grand Scenic 3 2011 1.6dci. And I have 2 errors. One is turbocharger underboost, and second, particle filter error. I take it to Renault service and they perform until now 2 times force regeneration. Now after 200km I have same error, and it stink like burning plastic.
I m tired of their service. Can you please say what I must check in next service, because they perform only force regeneration...
Thanks in advance. And keep the good info on your chanel..
I got a quick question for you I live in Canada and have a 2018 transit 250 getting a low temp code for the dpf had it to ford I'm wondering if this year has the vaporizer on it
" things ive learned about DPF's. Transit its the vaporiser. Honda's is oil dilution..Cheers
Hi, I have a 2012 Peugeot Boxer with a strange issue. the van has no engine lights on and not in limp mode but once it gets to temperature it starts smoking a lot, I can hear the vaporizer fuel pump pulsing which suggest to me my smoke issue is the vaporizer glow plug not working. My son is a mechanic and he has scanned the van and tested the vaporiser for blockage and all's fine. The DPF values are all ok as well.
If I was closer I would come to see you, would it be possible to point me in the right direction?
great informative channel👍👍
So I will ask different: will you fix problem straight away or keep replacing parts? Customer still pays ;)
Do you know of anyone doing this in Ireland jimmy?
Kennedys garage county Waterford
Great job as always 👍😃
So the parts darts special then? lol
They must be completely monkey if they didn't realise the reason why the DPF didn't get hot enough is because there was no diesel saturating it to make the temps required possible.
Did they fit a broken fan to make the DPF get hotter ?? Crazy.
Listening to you recall customer's stories reminds me of an experience I remember. Some years ago a friend of mine got this diesel 'mechanic' to come and look at his Vauxhall Astra at his home. This 'mechanic' bloke decided that the solution was 'to give it 24 volts'! I kid you not, that is what he said. The short of it is that the bloke was going to hump start the car and was absolutely convinced that putting one 12 volt battery in parallel with another 12 volt battery resulted in 24 volts! To my mind, if someone does not understand a most basic principle as this yet specializes in fixing vehicles should not be doing this job or possibly any technical job.
In all professions you’ll find people that aren’t willing, or aren’t capable of learning, either from their mistakes or learning to be better at their job.
Me ears hurt!
Recent subscriber, love your videos, just noticed you're based in my old home town, You're about the only good reason I can think of to move back there😂. I might book you for some work next time I go over there visiting..
Top job who is nice to know how much the mileage is on these vehicles and how old they are. Thank you
Great explanation Jimmy.
Though parts at it and if that doesn't work send else where.
Only other fault I've ever had is the fuse gone on glow plug on vaporizer valve which was down too the plug going to short still amazes me amount of garages that struggle with a simple fault
The brake pad wear light is nearly always caused by the sensor wires being cut in two at the back wheels . Common fault with transits.
hi whats the Tool for scanning you are using? is it Autel?
Whats the symptons when its been running rough ? Just curious to know .
Was it bye any chance wing mirror outside temp sensor
Where are you based ?
Biggleswade uk
You are the lord of the vans !
DPF faults. Will 20mph speed limits cause them to happen more often ?
Absolutely
How would changing glow plugs affect EGT ???????
It wouldn't. But his mechanic seemed to think it was worth a try at £350
Have you had to work on a 2017 Nissan Navra with DPF issues?
Would like to have seen a reply to this as I have an issue with a 2010 pathfinder, can't get through a regen and very low on power.
It’s great to have a master technician who understands these systems jimmy, keep up the great fight 👍👍👍👌
Thanks 👍
DPF👑🇮🇪👍
Hi mate, will a Dpf tempratuer sensor on bmw 730d cause a dpf efficiency effor if the temp sensors are.faulty
Yes
@@ORileysAutos ah mate so thankyou for fast reply, I have changed everything, from dpf pressuer sensors on the top, the rube hosings, egr cooler, scr filter , deep oven dpf clean, the error p2002 dpf effeicny low keep returning after every 500miles, now the mechanic and bmw.suggest its the dpf tempratuer sensors that go direct.into the dpf filter, could that be the cause of dpf effeincy low error
Please if you could let me know if the dpf tempratuer sensor that go direct into the dpf will cause dpf effeincy error , would be great help thanks mate
@@ORileysAutos ???
Great job Jimmy as always 👍
Thanks 👍
Hi Jimmy
I have mini countryman 2l dsport issues with dpf ,my garage as had it looked at over and over still can't get to the bottom of it .
Taken car to main dealer who said it needed new dpf filter £2300 !! Need 3rd opinion pls
Are you local to Biggleswade
@@ORileysAutos no I'm in preston Lancashire
What was the make of that blowtorch please?

Thanks.
Fantastic explain for everyone who think "i fix all". I am mechanic 30 years, but learn every daj about new staf. On TH-cam, google,frends etc.
And logic, replace fan for heat up ???
