Why Does Ford Transit Still Have Blocked DPF After 4 Mechanic Visits & Various Parts Replaced? 

I’ve had a DPF problem since Jan and I watched sooooo many of your videos and managed to do it myself and reduced the soot levels from 169% to nearly all clear, no more limp mode, engine light off and driving like a new car! Been 2 weeks now 👍🏼 Thank you 😊

Can't get enough of Jimmy's videos, keep up the great work Jimmy !! You'd make a great instructor, logical thinking and step by step detailing, just fab !

DPF was the worst invention ever for the diesel. They are always prone to falling and mechanics ,as you say, seem clueless as to how to fix the issues. Thanks for your excellent video

been in the trade for 36 years and I'm still on a learning curve. you never stop learning in this trade

I’ve learned more off two of your videos than a months worth of other ones. Thank you 🙏

These DPF filters are a scourge of vehicles today

Great vid...educational and no annoying music thanks

Cheers from the New England colonys ! Awesome video, unfortunately I don't get a lot of diesel cars and trucks at my shop however it's important to stay on top of things because someday I'll run across this and I will be prepared!

Just want to say a thank you for all your videos on transit customs and DPF's after spending a few evenings watching your videos I tackled my van this weekend and found a blocked fuel vaporizer. Sadly I couldnt get it out with the dpf attached so had to pull dpf out, you make it look easy getting it out. However a clean up with a blow torch reassemble and some dpf cleaner and 5 minutes of forced regen and now 0.5kpa on idle was between 3kpa and 5kpa before. Out for a test drive and no lights or limp mode! Thanks for taking the time to make your videos they are a great help!

Very interesting video, thanks for taking the time and trouble to load it!

Great advice as always Jimmy. Top Man.

I've a Nissan xtrail, 1st car I've owned with a dpf, the car was doing a regen nearly everyday, even the day after doing a long motorway drive. I got a fuel card through the blue light card, but it's only for Esso fuel, I save enough for it to be cheaper than supermarket fuel. Since going over to Esso fuel, my cars not done a regen in over 4 months Not saying changing fuel supplier would work for everyone, but it definitely worked for me.

Hey up Jimmy, just found your channel, someone who knows something, as nowadays everybody thinks they do 🤔, great technical details and the truth, really like this sort of stuff, thanks for sharing, ride safe, Simon B 👍

You're really good at teaching mate, I enjoyed watching this. Thanks for sharing

Life of a motor mechanic a lot of learning every year.

a guy that knows what he's doing...bravo..knowledge is worth every penny and what you pay for.

Just found your channel I am in my late sixties and not up to speed with all this new stuff. But still find it very interesting. Thank you so much for making these videos. You tell it as it is. Regards Raymond 🏴󠁧󠁢󠁳󠁣󠁴󠁿

Sir, it is knowing how to access the info, what is needed to rectify the fault, then using correct parts to complete that, Your videos highlight this brilliantly

Sorry I forgot the 3.2 Ford diesel is an American model Transit, 350 HD, 2017. The van is in America and I'm in Thailand trying to trouble shoot its many problem's. Not a lot of people know the engine very well. The glow plug problem hasn't even come up. Again thank you very much for what you do to help people.

Wish I knew good mechanics as good as you fantastic job and video

Great video. Thanks for the insights

Hi jimmy just come across your channel. As a mechanic my self for 40 years + in the trade working in a dealership ford being one of them . And I agree with your comment on the heater plugs can you do a video on removing them 😅 . Keep up the good work and the videos coming 👍

Another top video from the top techs,thanks for sharing

I've had to saw the vaporiser off the nut many a time to get a socket on and crack it off. You've got some nads replacing them on the street, bro! Fair play.

great video , great content and Jimmy fixed it again ......

New subscriber here, you definitely know your stuff. Great to watch, good work!!

If only garages had reliable knowledgeable people like you fella Nice one Thanks

Never likes forced regens - seen an exhaust go so hot the fuel tank melted 😮 your a master of your trade 🙏🙏

Great video mate. What is critical for dpf systems is when vehicle gets an oil change you must reset the oil data and service reminders as the systems only know if you tell them. Otherwise the system thinks it hasn't had an oil change and thinks the oil is diluted and will not complete regenerations.

Well done mate! ✌️👍🇬🇧

Hi Jimmy! Love the videos Wondering if you could help a welsh lad currently stranded in Canada. It’s a Ducato 115 multijet, 2l, 2014 I’ve located the dpf which sits vertically behind the radiator. Just wondering if you know which is the 02 sensor or which bolt I should undo to start the process.

I run everything that puts a load to the engine, like the ac on full blast, heated seats, heated windows etc so the exhaust Temps rise more... It actually helps out alot!

Great information. Thanks for sharing. We have a 2014 460 minibus adblue. Should we be looking at getting a dpf service as a preventative measure?

You are great man You are boss for all dpf story thanks man

Been watching most of your videos now, you,re dam good at your job .:-}

On transits during regen the engine glow plugs come on when the engine is in over-run. When putting throttle on, the vapouriser pump hz will increase proportionately up to a max of around 4hz pulses as the increased combustion heat allows more vapouriser fuel to be injected without visible white smoke appearing from the tailpipe. Conversely, when in over-run the pump hz will ramp down to zero (stop flow to the vapouriser) and the glow plugs will come on. At this time during over-run the throttle body will close more to gag the air flow to try maintain DPF heat until load conditions mean heat can be restored. As soon as you ease your foot back onto the accelerator the glow plugs will go back off and the pump hz will ramp back up again. The vapourizer glow plug stays energised throughout. Debatable how much influence the cylinder glow plugs heat has on the combustion or regen heat process during this small operating window or whether it is mainly to load the engine up via load on the alternator in the same way as the heated screen comes on (60A load) during regen.

Jimmy keep them coming - every day is a school day as far as I’m concerned - I can see a 2017 plate Vivaro coming down to you on a trailer soon 😂 I’m on my third attempt here just waiting on the launch gun to give me the FOAM action which you shared the other night 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

I’ve got a sprinter that is showing many of the same symptoms as this it’s been to various Mercedes specialists, merc main agent and a local garage and it’s no better. DPF was taken off when it was having a clutch two months ago and acid bathed light back on with less than 1000 miles since.

Well done, good man!!!!

Brilliant video well explained

Good video Very informative!

Well done. Great info

I was having DPF problems for a few years with a 2012 Transit , the van is sold now but its just a pity I didn't find out about you sooner I'd still have the van .

Great lesson thank you

At what millage should the glow plugs be changed as a maintenance item, doing 100,000 miles per year? Just found your cannel. WE have a 3.2 ford. Thank you very much.

I used some Launch Flow restored and after the second tank full popped the vaporizer off and it looked almost completely clean. Think I'm going to use that every 3 months or so as preventative maintenance.

It's seems to me that most of the large garages seem to plug in thier diagnostic tool cancel the fault then take your money and do nothing else.

Interesting stuff, not sure how similar a 2012 Subaru Outback diesel system is but my mate bought one a while back with 50k miles, not long after purchase the money light came on and it went into limp mode so he took it to the local garage, something like £1200 later with some new parts and a dpf clean he got it back, there were signs the dpf had previously been cleaned and the garage said chemical cleaning doesn't work (which my friend now takes as gospel) so it was sent away to be burnt out? or something, anyway the garage said it possibly wouldn't work, later on the eml came back and it went into limp mode again so he took it to Subaru, a new dpf and parts for something like £2500 and it was meant to be fixed but by then he was paranoid it was going to go again so recently part ex'd it on a Hyundai.

I know with manitou forks if you go too easy on them you have dpf filter issues, but you need to keep the revs up to keep the filter right

excellant work

Jimmy come up to Glasgow please sort my merc, love your videos and work.

Good man, keep up the good work with the videos. I am thinking of coming up to you for some work on my Touareg, but what is your preferred / normal working area.

Glow plugs fault can on some vehicles put ecu into a un noticeable "safe" mode where dynamic regeneration won't ever happen hence why the dpf eventually clogs up. They are also utilised as a load on the engine during regeneration

Coming from an hgv perspective where scr systems and dpf etc are far more complicated than on any modern car or van I’m absolutely flabbergasted as to how garages can’t seem to fathom these systems out 😅 I’ve even come across a Peugeot Citroen expert who didn’t even know what the fap fluid was actually doing in the system thought it was being injected into the exhaust by the adblu injector i mean Jesus come on fella lolll

Does this model have the 2 air filters? Worth replacing them at the same time?

My Relay was starting to smoke rather bad but after doing 400 miles in a few days it seemed to have cleaned itself out. That's one thing my van didn't fail it's mot on ha

dpf light came on my Mk4 caddy and just ran the the Vag Group DPF regen as per the instructions never heard from it again and sold the vehicle with a clean histrory.

Did you buy the extended prope for the launch dpf cleaner, i mainly do volkswagen cars, and would have thought i could use the standard prob, if that was the one you were using in the video via the pressure difference sensor pipework.

Hi mate, was there a code for the exhaust pressure sensor or did you just go off live data readings? Thermostat replaced? Great vids, keep up the good work

Tbh the part name itself is pretty cool: A Vaporiser!

Hi love your videos how to clean dpf on peugeot 5008 2.0 hdi from 2012 .

Great video I have to say you no your stuff about the workings of these dreaded dpf’s

Great video and very good explanation on how to fix the issue, i'm looking at buying a 2014 Transit custom which the seller has stated there is a exhaust filter issue hence price! I'm assuming its the dpf also and has same issue , where can i source the same part make you use as there are so many chinese ones online and i need a decent trusted part. Thanks :) Luke

Best thing to do is get all the emissions crap removed. DPf filters and EGR valves kill engines. When emissions things are removed the MOT test results are better than before, also engines produce more power and better MPG.

I currently have a transit in with blocked dpf that a mobile cleaning company couldn't unblock so I'm removing it to be cleaned properly. I've also found the vapouriser blocked and have codes for 2 glow plugs . Will the glow plugs stop a regen in the future as don't really want to do them lol

When I worked at Ford. We were changing vaporisers on transits every day

Like any part on a car they don't last forever I had problems with dpf on BMW 318d I had it regenerated all faults on dianostic disappeared I eventually replaced dpf had no further issues

Hi jimmy , I have a 2015 Ford transit 350 2.2 tdci mk8 euro 5 Blowing white smoke out of exhaust no loss of power no engine lights etc driving 100% Do you think a cable tied injector would cause the issue randomly smoking

is it possible to manipulate the DPF into regeneration mode by maintaining a certain engine speed at a certain RPM , gear ? and do these extra additional regenration modes prevent these problems.

It's not just mechanics, it's everyone. I had a Mercedes E220d Convertible with a soot content of 400%. The key thing is what does the vehicle manufacturer count as red lines and what do they consider grey lines in terms of DPF regeneration cycles running naturally. Using Autel 806 I was able to let the car know the DPF had definitely been replaced, no, honestly. Then making sure that the red line of the EML not being illuminated does not prevent DPF regeneration drive the vehicle whilst keeping the measured PIDs as close to the perfect conditions as possible. In my particular case the engine speed was specified as between 725 and 925 RPM. This is in no way keeping the car in a lower gear and higher road speed to keep the revs high. This does nothing. On a vehicle that has a functioning DPF regeneration system you will see the optimal differential pressure value fluctuate between +1 to +16 and two negative values which can not be returned by the sensors. When the value is in the possible range you will see the exhaust temps rise from 300's to 600's as the system works and these will drop back when the range switches to the nonsense values. This is how the system is set up on '13 Mercedes 180, 200, 220, 250 diesel engines. I got this vehicle to return soot content of 72.5% and 77% the last two times I checked over the last 3000 miles of normal mostly urban driving. It took 3.5 trips on the A34 between Oxford and Newbury to get the DPF to stabilise at a normal fill level. No physical work was done on the vehicle except the Differential pressure sensor was replaced at owners request as the last "Parts Grenadier" told him it was necessary. I also used one tank of fuel with a non specific additive to run this process. The key TLDR message is get a live data scanner which gives you the PIDs you need to monitor for the DPF system to optimise the conditions needed for your manufacturers system. Plus EML illuminated is a red line for every manufacturer. Also don't believe everything you read on Google... Thanks for coming to my TED talk!

Launch is the best, I only recommend Launch.

I heard somewhere that the new Peugeot boxers with the 2.0HDI using these ford engines? Or is that only the 2.2? Thanks for your work.

Saab do the same. Failed regen because the thermostat is stuck open. Can't reach system requirements. Can the vaporiser be stripped and cleaned?

Catch 22 other faults cause regen cycle to fail to prevent the dpf burning out/melting but it then blocks the dpf and refuses to regen at all even after the first fault is fixed. Clogged adblue injectors cause nox emissions faults (selective nox efficiency below fresh hold) which prevent regeneration, leaking as blue can also completely block the exhaust with urea salts showing as a clogged dpf.

A couple of years ago a car guy in stralia called John cadogan was talking about the Toyota hilux dpf issues and one of his theories was a air leak in between the air flow sensor and the engine.

It helps if you put premium diesel and keep it full. Not heating oil...😅

Hey Jimmy, now you've had your new launch scanner a while, how about another quick vid on its ins and outs. . Assuming you're a bit more familiar with it. Cheers bud.

Hello mate. I’ve got a 2013 mark 7 transit. Had Dpf problems for months, had the vaporiser and bank 1 sensor 3 changed, engine light still would come back on after. Now the engine light has stayed off but the powertrain light is on permanently, would occasionally come on when I would drive at high rpm to try and force a regen but now it’s on constantly. Never has gone into limp mode the whole time I’ve had the issues with it. I’ve spent nearly £1500 in 6 months on it. Bar going to Ford and bring raped with their prices I’m at a complete loss. Any advice please mate?

Getting a 2005 van ,older than what i have now but no dpf fitted.simples

The custom has got a dangerous safety problem. The design of the air intake for the heater it lets fumes from under the engine bay though the windscreen wiper arm holes and some small grills the fumes the get sucked into the cabin. The exhaust needed to exit at the rear not half way down trapping the fumes

glow plugs on transits are only used for starting.

DPF. One of the major problems is understanding why it fills! Less foot on the pedal stops generating the soot in the first place. DPF systems rely on the temperature sensors to regen.

Great video 👍🇮🇪

At the first sign of problems with mine in getting it cored and welded

Amazes me why people won't pay for a clean after a new part is fitted.

Glow plugs are used to help start with low emissions and also in many cases they are used during warmup. If a glow plug has failed that cylinder is less efficient and the engine will have a different performance from that cylinder during warmup. This torsional shock on the crankshaft will damage a dual mass flywheel with all of that cost! I had that conversation with a LUK Dual Mass Flywheel Technical rep. Also crankshaft dampers on the front of the engine if they fail the Dual Mass Flywheel takes all the Torsional vibration and fails early. False economy do the glow plugs.

I'm getting a knoc sensor fault and the ad blue tank isn't tracking the level in the tank. It's ful but only says no engine restarts in 250 miles . Ad blue dosing malfunction

bit late to the party ,how would you do a dpf that was pre vapouriser ,would you just do the dpf clean? cheers ,my transit doesnt have one thankfully but i had a mk4 mondeo 2.2 that went into limp due to dpf shame because it were a great car up to that issue

Still good videos for the community, to your knowledge does a autel 808 do DPF resets for vauxall vivaro I know you had one years back ??

See you in Luton Euro car parts all the time 😅

Absolute swine to get at and get out those vaporisers I struggle on a lift you got my respect doing on ya back. That euro tab 3 is very quick.

I solved myn took it off pulled dpf out left cat in had it deleted along with egr never had any issues since been off 3 years now my engine can breathe and still passes mot emissions

Can I do away with the dpf have remapped and if I do will it put the dpf vaporizer light off

No need to replace the vaporiser. Drill a hole in the flat end, clean the carbon out and put a spot of weld over hole you have drilled. It’s a 10 minute job with the vaporiser on the bench.

a lot of them havent got a clue i had 2 mobiles 160 later light still on my mate took to his man and just plug in and sorted it out 30 pounds for his time dpf been good no for 6 months

Had this on a Audi dpf blocking all the time never changed the glow plugs

Top man

I knew it was fifth injector before I even watched the video :) I drill the end of them unblock them then weld the hole back up

Please, maybe you can help me, I changed the Dpf filter 3 weeks ago on my Ford custom, and now the problem is back again. Do you have any idea what the problem can be ?

Is the Thermostat jammed open? (148,000+ mile)
