I had a power problem and then a 'soot filer is full' message on the dashboard. After seeing this video, I was able to spend about 20 minutes in the car on ordinary country roads, typically between 3k and 4k revs, and it worked! Great video, and thanks for the tip!
Diesel particulate filter regeneration is not obtained by "blasting it out". The DPF has back pressure sensors fitted, when the ECU determines that the filter is becoming clogged it illuminates the warning light. To regenerate the PDF you need to hold the vehicle speed between 50-70 mph, this massively increases the DPF temperature and the ECU then goes into regenerate mode and injects diesel on the exhaust stoke. The unburnt diesel enters the combustion area just before the DPF and is ignited which raises the DPF temp considerably which burns off the contaminants. While driving between 50-70 mph it is important that you do not stop or slow down or the whole cycle has to start again. If the PDF is badly blocked, PDF cleaner should be added to the fuel which reduces the diesels combustion temperature and helps to ignite the fuel in the chamber at a lower temperature. Revving the nuts out of a diesel engine to 5k does nothing but harm. The whole business about diesel engines being bad for the environment in the instance of London is pure claptrap, the exhaust gas from my 2.9 ltr diesel is cleaner than the air passing the air filter. Most of London's pollution is made by poorly maintained public service vehicles....take a look at the next bus or black cab you see pulling away and watch the clouds of blue/black crap coming from the exhaust. The modern private diesel engined car is just being used as a Councils cash cow. London's pollution wouldn't have anything to do with Gatwick, Luton, Stansted, Heathrow and City airports operating a plane stack directly above would it by any chance?

Same problem happened with my 2003 vauxhall astra 1.7dti. Bought it from an old guy who used it for very small commutes. Only did around 500 miles a year. Dpf was blocked to the point where in every gear it wouldnt rev past 2.5k rpms and was so slow getting there. I didnt watch any videos on it but i just kept on pushing the car to red line in every gear. At first it pushed out tuns of black smoke but after doing that for around 30 minutes the car started driving normally and the problem was fixed. Ive not had a problem with the car since and it runs butter smooth. So i can vouch for this video. This method really does work!
So you have to do this in evrey gear until the left arrow reaches 5? And then going back from first gear to the last gear half hour long? Or do you have to do this once and maintain driving 30 minutes long ride?
Rather than risking possible engine damage or a breakdown, it would usually be better to remove the DPF and wash it out. You can either have this done professionally for a cost, or you can do it yourself for a the price of a couple of dishwasher tablets and a few grams of oxalic acid powder that you mix into water. Plenty of videos on TH-cam showing how this can be done, and if you don't rush it's just as effective as the professional service you pay for. Don't forget that a DPF is usually only blocked as a result of a mechanical fault. Performing a regen, forced or otherwise very often only buys you some time before it becomes blocked again. An investigation and a series of tests should be carried out to ascertain the cause of the blockage. Under normal driving conditions a DPF would be expected to last at least a hundred thousand miles before any intervention would be necessary. Basically your DPF is a filter, every time the engine wants to emit soot the DPF catches it to be burnt off safety during a passive regeneration cycle during driving. However if your car emits more soot than it should then the DPF will soon start to clog up as the regen cycles never remove 100% of what they capture. Obviously the dirtier the engine is running the faster it will clog. There's a myriad of reasons why the engine might not be running as cleanly as intended. Such as: poor servicing (dirty oil or clogged air filter), blocked engine breather system or faulty psv valve, EGR system fault, mechanical wear, turbo system fault, fuel delivery system fault, such as worn injectors. And one that's thing that's often overlooked, glow plugs! Without these functioning properly the engine is not able to perform a passive regeneration cycle, they are required to ignite the diesel that is injected during the exhaust stroke in order to heat the DPF to a sufficient temperature to burn off the soot etc. So as you can imagine there's often considerably more to take into account than simply the DPF itself!
I came across this video yesterday after the check engine light went on. I did exactly as you described here and the check engine light went off after 10-15 minutes drive. Thank you very much. It was quite helpful. From now on i will do regular manual DPF regeneration :)
I think it is time to make the DPF structure easier to clean. It is not eco-friendly to use special equipment and solvents forever. The manufacturers should change the DPF structure so that it is as easy as replacing the engine air cleaner.
I was thinking the exact same thing why can't they just engineer a certain type of filter you can just pop out and pop in because all this regeneration stuff is just bull crap

DPF, reduces NOX.... DPF regeneration needs a decent 20min constant run.. or on mitsubishi trucks it has a button that for 20mins will do a forced regen that holds the revs at 2500 ish
Thank you with excellent work. i just did the engine overhaul on Navara D40, but i cannot stort it up. It shows P0336 continuously and keeps on hesitating to start. Any idea what perhaps I am missing?
This DPF problem is a pain in the back side. Above 40 mph and 25000 rpm for about 20 minutes is more than enough for a regeneration. And regeneration can also be done just on an idle car through the vcds.
Anyone that don't work on cars or don't know how to fix cars wouldn't understand.... I got a few cars and when someone driving diesel cars with the dpf pottering around town low RPM because car makers in the "Infinite wisdom" keep diesel engine rpms below 2000. Which is good for fuel economy but kills the DPF as it never gets hot enough. I've taken what the mechanics basically said you need a DPF replacement bud. Vehicle in limpmode DPF almost blocked to a point where the car was hard to start. "Mind you old bird" 200k miles. It capacity to hold ash probably getting to it limit as well. Filled it up with DPF cleaning agents 2 bottles of it as prescribed in the tank and the went on a long highway speed road trip 9 hours.... Got back to base it didn't do shit so I thought & went through an entire tank of diesel plus 2 bottles of this garbage "I thought". Next day though I filled up the tank again with 1 last bottle at the concentration for maintenance. Drove it to the shops still in limp mode & still no turbo... It was that bad but still it wasn't final stages of "Limp mode" where it would limit speed up to X & 3000rpm max. I could still go to whatever speed the engine gave me rpm up to 4k. Got back in the car from the shops and out of the parking lot at the traffic light i notice the DPF light flashing then it turned off and the light turn green. Normally I just plant my foot all the way down because been reduce power it takes the foot been planted all the way down to just move it. This time when I did that the vehicle wheels spin out and launched! Cleared the blockage. Mechanics wrote it off but I didn't.
I bought a diesel, wife bought a diesel. We didn't know dpf's existed until now. We drive normally and neither have had any problems. 130,000 miles and 85,000.
All depends on vehicle manufacture. Peugeot/Citroen (and some other manufactures) from around 2000 onwards use some form or other of "Fap" or "Dpfs" system where a separate tank or bag reservoir holds a very expensive regen fluid which is injected into the common fuel rail via a separate injector and controlled by a ECU. The refill of the tank unit is part of the service schedule. Other cars such as my Jaguar do not use this system but works by over injection. Either way, providing your journey's consist of a regular uninterrupted 50-70mph run of around 15-20 miles you shouldn't have any problems. Just using the car for low speed, low journey distances and you will have to go through a DPF regen routine!
Same here pal, got a mk7 Golf GTD, driven normally, no issues. If it starts a regen when i get parked up, i will hold the revs at 2000rpm, letting it complete the regen. I have a scangauge connected to the obd port. This reads exhaust gas temperature, around 2000rpm it is at its highest, higher rpms the temperature decreases due to high air inflow.
Probably easier taking it off and cleaning it manually. However this process will do the engine no harm whatsoever. Its an engine, this is what it's designed to do and well within its tolerances
@@westyorkshireengineservice9160 mate its done billions and billions of revolutions before that so another 100k won't do any harm. Especially when it's hot

I have to do this periodically with my 150ps Zafira 1.9 cdti. Eventually large clouds of black smoke come out and then everything settles down back to normal. Using premium diesel fuel (yes expensive I know) whilst doing this helps. Being sure the timing chain/belt is good is essential !

I am in Australia and have a 2011 R51 Spanish built Pathfinder. Does it have DPF?. I dont have a DPF warnin g light on my cluster. Do these cars have a DPF warning light?. Do they have a DPF filter ? Many Thanks
Have a peugeot 807 Hdi, FAP warning low on for long time. Put three ltrs in. Car only done 150k over 15 years. No acceleration power, starts good and ticks over nice. Feels like air starvation . Cleaned the AIR INTAKE assembly. fault Poo26. Wondering if its the DPF... could it be? Not sure if I could be brave enough to 'leather it' as in the vid.
Hey mate love what you guys do!!! Im after some help, 08 d40 I've done a dpf delete, fuel filter, scv, injectors, boost solenoid, its still blowing heaps of black soot and is very slow on take off any ideas? Car is doing my head in!! Cheers
Turn the heater to cold, you want that heat in the engine not the cabin. How the regeneration works is the ecm injects fuel on the exhaust stoke, that fuel ignites in the exhaust & raises the temperature to 600°C plus which in turn burns all the soot that has been caught & trapped in the DPF. Heavy acceleration produces more soot due to unburned fuel. What is worth knowing when owning a DPF equipped diesel vehicle is does the ecm detect that the system is getting blocked using a differential pressure reading or does it just automatically regenerate based on fuel usage & or mileage ? If it’s a system that just does regenerations at set intervals then the blasting around in low gears is a waste of time, money & you are blocking the DPF more than it is already IF the system is not ready to regenerate. VW TDi engines now have the DPF close enough after the engine that when the engine is up to normal operating temperature the exhaust is hot enough without the need of post combustion fuelling to burn out the soot.
I have a vw passat cc 2012 2.0 TDI 170 bhp .I had blocked DPF .was too bad to the point the engine stall. all 4 injectors gone . there is raw fuel in the exhaust does that has a relationship with the DPF regeneration or injectors are bad . now we are not sure if the DPF was blocked and damaged the injectors or injectors are faulty and failed the DPF regeneration
Very informative video wish I'd seen this a couple of years ago, my son spent around £800 when this happened to his Polo. Ive recently bought a diesel Focus, the owners manual says the car will automatically do a DPF Regen when its required is this true, or is there something I can do to keep the DPF clean Thanks
i had a similar problem but i figured out that turbo didn't worked properly so i made some checks and found out that a plastic raper pipe connected to a vacuum was damaged so i change it and was fixed at the same moment....
Keith D Hi Mr D lots to say but looking at your channel not much to say well did you go to part 2 and also the customer asked us to do this which worked and was far cheaper than replacing parts so thanks so much for watching buddy hope you have learnt so much from the video it does not need to cost the customer a arm and a leg 🦵
You must be a daft low IQ fool who doesnt know anything about DPF systems, this is EXACTLY how you put your car into a forced regen if all other methods have failed, if you dont like the method then get ready to buy a £1000 - £1500 for a new DPF.
Sohail Ashraf that depends on the vehicle. My F350 would go into limp mode to keep a knob like this from destroying it. Besides you can manually regenerate it via diagnostics tools.
Coincidence, took my transit on the exact same route the other day trying to initiate a regen, didn't work though so had to spend £500 having a new vaporizer fitted
Hi, Excellent vid! Can you advise me on how to drive my Ford Mondeo Mk4 estate 2ltr tdci 2010 plate, that the DPF warning light has just come on? What revs should I do on the motorway to activate the regeneration system? Any advise greatly appreciated. Thanks!
Removed my dpf 3 years ago. Never looked back since, no issue with Mot, no constant big repair bills in forcing a regeneration. If you keep doing local trips it will clog up over and over again
Will try on my Ford Transit Custom 2.2l 2013 tomorrow. I have fed up with bloody dpf blocking 4 times since 1st UK Covid lockdown. Have already paid over £400 and dpf keeps blocking 🤯
I assume this is one of the cars that won't get back to the customer - at least, I hope not. What this dodgy mechanic doesn't seem to realise is that while short journeys or bad driving can cause some DPF issues, a badly blocked DPF is almost always hiding another engine issue - injector problems, turbo issues, oil consumption or even just O2 sensors getting on toward end of life causing 'rich' fuel mixture (yes, you can have that on a modern diesel). Ruining the engine like this to try and burn the soot out of the filter won't address the underlying issue - so the car will simply be back again. . .assuming the engine doesn't blow up first after being driven like that.
I don’t understand how… I have a high mileage r51 jusy like this one I only use it in the city over the winter months , and it doesn’t get clogged … how bad are people using their cars to bring them to this point ?
My DPF when it starts a Regen this is what happens (1) loads a white smelly smoke (2) My temperature gauge goes to 0 (3)MPG goes down loads and when idling mpg usually sits at 1 but in regen it sits around 9. I have to give it a thrashing in 4th over 2000 revs for around 10 mins then temperature gauge starts going back up to normal running temp I now know its finished. Vectra C 2006 Remapped 150bhp - 210bhp DPF delete and blocked off flaps glued open but NOT mapped out yet

No milage and amount of regenerations it has done
also when you have oil change, get it engine flushed as it will remove crap etc.

Got back to base it didn't do shit so I thought & went through an entire tank of diesel plus 2 bottles of this garbage "I thought". Next day though I filled up the tank again with 1 last bottle at the concentration for maintenance. Drove it to the shops still in limp mode & still no turbo... It was that bad but still it wasn't final stages of "Limp mode" where it would limit speed up to X & 3000rpm max. I could still go to whatever speed the engine gave me rpm up to 4k.
Got back in the car from the shops and out of the parking lot at the traffic light i notice the DPF light flashing then it turned off and the light turn green. Normally I just plant my foot all the way down because been reduce power it takes the foot been planted all the way down to just move it. This time when I did that the vehicle wheels spin out and launched! Cleared the blockage. Mechanics wrote it off but I didn't.
I bought a diesel, wife bought a diesel.
We didn't know dpf's existed until now.
We drive normally and neither have had any problems.
130,000 miles and 85,000.
Wait for it, its about
All depends on vehicle manufacture. Peugeot/Citroen (and some other manufactures) from around 2000 onwards use some form or other of "Fap" or "Dpfs" system where a separate tank or bag reservoir holds a very expensive regen fluid which is injected into the common fuel rail via a separate injector and controlled by a ECU. The refill of the tank unit is part of the service schedule. Other cars such as my Jaguar do not use this system but works by over injection. Either way, providing your journey's consist of a regular uninterrupted 50-70mph run of around 15-20 miles you shouldn't have any problems. Just using the car for low speed, low journey distances and you will have to go through a DPF regen routine!
Same here pal, got a mk7 Golf GTD, driven normally, no issues. If it starts a regen when i get parked up, i will hold the revs at 2000rpm, letting it complete the regen. I have a scangauge connected to the obd port. This reads exhaust gas temperature, around 2000rpm it is at its highest, higher rpms the temperature decreases due to high air inflow.
jon townsend - it’s a good system on this year VW’s. My 11 plate Passat CR170 is on 185k miles and no issues with the DPF.
The problem comes if you only do short journeys and stop start driving..
Probably easier taking it off and cleaning it manually. However this process will do the engine no harm whatsoever. Its an engine, this is what it's designed to do and well within its tolerances
gaffnaldo1 Nice to see someone else has a understanding of diesel engines
@@westyorkshireengineservice9160 mate its done billions and billions of revolutions before that so another 100k won't do any harm. Especially when it's hot
In my neck of the woods that’s called an Italian tune up.
I need the Italian tune-up. No wonder my Passat TDI is shitting all over me with this DPF regen crap. I am usually around 2000 rpms, and little else.
Top man. Thanks
Would this work on my 2011 Mazda 3 Diesel Sport?!😖
DPF light has been flashing a few days, tried to do stuff like this but no such luck yet😖 the power doesn’t appear affected at the moment, no limp mode, but I just want the light to switch off😫
Do I just keep doing it?
Dpf is sorted but now needs a set of bigend shell's! 😂
i see bud ,, but sorry you are wrong the cars are made to do this the makers a not daft or you can get your self a maxicheck pro it will do a froced re gen
Would this be considered limp mode due to it struggling?
This was an amazing and very helpful video. Will be giving it a try soon to hopefully sort engine code! Thanks for sharing!
Tony G you also need to watch part 2 All the very best Des
@@westyorkshireengineservice9160 OK will do 👍
Tony G Hope it works for you buddy
@@westyorkshireengineservice9160 Indeed, floored it from first gear to second gear but only got to 4,500 revs. Would not go any higher! BUT all aside I have actually noticed a difference in response afterwards, already. So Thanks
There's a lot to be said for getting a diesel hot and hammering them,had diseasels for almost 20 years now and no emissions problems.they need working
gotta drive em like you stole em thay way theres less regens
does the engine light go off on its own after doing this. this is the only vid ive seen that is the same as what i have done, so thanks. i have a iveco daily
Do you get tonnes of back pressure when a DPF is blocked?
I have to do this periodically with my 150ps Zafira 1.9 cdti. Eventually large clouds of black smoke come out and then everything settles down back to normal. Using premium diesel fuel (yes expensive I know) whilst doing this helps. Being sure the timing chain/belt is good is essential !
Good old italian tune up :D
Mans in my neck of the woods baby! Birkby, snakes road!
i would like to take some advise... here is what is happening to my Nissan Navara 2007 d40...when i try to overtake or accelerate fast it's going in safe mode...it stops accidently to accelerate and it's not even going 3000rpm with the gas pedal fully pushed ...to go in regular mode again i must switch it off for some seconds and then start again... what is it??? is it a sensor???
I have felt all that pain with my transit connect
I am in Australia and have a 2011 R51 Spanish built Pathfinder. Does it have DPF?. I dont have a DPF warnin g light on my cluster. Do these cars have a DPF warning light?. Do they have a DPF filter ? Many Thanks
please make tutorial use seafoam on d40 intake cleaning/injector
Have a peugeot 807 Hdi, FAP warning low on for long time. Put three ltrs in. Car only done 150k over 15 years. No acceleration power, starts good and ticks over nice. Feels like air starvation . Cleaned the AIR INTAKE assembly. fault Poo26. Wondering if its the DPF... could it be? Not sure if I could be brave enough to 'leather it' as in the vid.
Just wondering instead of doing what you’re doing, can I warm up car and just hold at 4K rpm, that should clean it, no!?
Hey mate love what you guys do!!! Im after some help, 08 d40 I've done a dpf delete, fuel filter, scv, injectors, boost solenoid, its still blowing heaps of black soot and is very slow on take off any ideas? Car is doing my head in!! Cheers
Also egr is blocked
Good video guys
Hi does it work if i raise the accelerator without drive the car please?
Turn the heater to cold, you want that heat in the engine not the cabin.
How the regeneration works is the ecm injects fuel on the exhaust stoke, that fuel ignites in the exhaust & raises the temperature to 600°C plus which in turn burns all the soot that has been caught & trapped in the DPF.
Heavy acceleration produces more soot due to unburned fuel.
What is worth knowing when owning a DPF equipped diesel vehicle is does the ecm detect that the system is getting blocked using a differential pressure reading or does it just automatically regenerate based on fuel usage & or mileage ?
If it’s a system that just does regenerations at set intervals then the blasting around in low gears is a waste of time, money & you are blocking the DPF more than it is already IF the system is not ready to regenerate.
VW TDi engines now have the DPF close enough after the engine that when the engine is up to normal operating temperature the exhaust is hot enough without the need of post combustion fuelling to burn out the soot.
I have a vw passat cc 2012 2.0 TDI 170 bhp .I had blocked DPF .was too bad to the point the engine stall. all 4 injectors gone . there is raw fuel in the exhaust does that has a relationship with the DPF regeneration or injectors are bad .
now we are not sure if the DPF was blocked and damaged the injectors or injectors are faulty and failed the DPF regeneration
Thank you for these valuable infomations
aqui no Brasil quando ta entupido o DPF recomenda-se pegar uma via rápida com o giro do motor sempre muito alto
Mitä??
I hope you don't get blown off the road the next time
Very informative video wish I'd seen this a couple of years ago, my son spent around £800 when this happened to his Polo.
Ive recently bought a diesel Focus, the owners manual says the car will automatically do a DPF Regen when its required is this true, or is there something I can do to keep the DPF clean
Thanks
Don’t do this, unless you want to break your car 😂.
That has to be one of the dumbest things to do with a blocked dpf.
7:47 coming up, coming up, coming up, its there :)
dirty
thank you bud
How do you do this same forced or manual regen' process on an automatic gearboxed vehicle?
How can I drive mine when it's bellowing out smoke, this is on a vauxhall zafira? Many thanks
i had a similar problem but i figured out that turbo didn't worked properly so i made some checks and found out that a plastic raper pipe connected to a vacuum was damaged so i change it and was fixed at the same moment....
If this guy is an actual mechanic I'm truly shocked. This is absolutely not how any professional would treat a vehicle with those symptoms.
Keith D Hi Mr D lots to say but looking at your channel not much to say well did you go to part 2 and also the customer asked us to do this which worked and was far cheaper than replacing parts so thanks so much for watching buddy hope you have learnt so much from the video it does not need to cost the customer a arm and a leg 🦵
You must be a daft low IQ fool who doesnt know anything about DPF systems, this is EXACTLY how you put your car into a forced regen if all other methods have failed, if you dont like the method then get ready to buy a £1000 - £1500 for a new DPF.
West yorkshire engine services a mechanic taking the customers advice and diagnosis. Brave.
Sohail Ashraf that depends on the vehicle. My F350 would go into limp mode to keep a knob like this from destroying it. Besides you can manually regenerate it via diagnostics tools.
Keith D You're gay!
There are companies out there that can power clean the diesel particulate filter now, for anywhere from between £150 and £250.
Coincidence, took my transit on the exact same route the other day trying to initiate a regen, didn't work though so had to spend £500 having a new vaporizer fitted
Hi,
Excellent vid!
Can you advise me on how to drive my Ford Mondeo Mk4 estate 2ltr tdci 2010 plate, that the DPF warning light has just come on?
What revs should I do on the motorway to activate the regeneration system?
Any advise greatly appreciated.
Thanks!

Thank you for your very prompt reply and advice!!
What is your view on DPF additives? Regards Charles
fortes dpf regen stuff is good.
Removed my dpf 3 years ago. Never looked back since, no issue with Mot, no constant big repair bills in forcing a regeneration.
If you keep doing local trips it will clog up over and over again
Anon Anon yes I totally agree with what you are saying but the law changed and if the mot garage suspect it’s been removed it fails the mot
Thank you better air quality
I thought if you removed a DPF the car would automatically fail an MOT test, FACT and your insurance would be invalid!
Did you have to get it remapped after you removed it?
@@brodiefoster3872 you have to reprogram your ECU without it.
Have a red filter light appear can I still fix this driving on the motorway
Will try on my Ford Transit Custom 2.2l 2013 tomorrow. I have fed up with bloody dpf blocking 4 times since 1st UK Covid lockdown. Have already paid over £400 and dpf keeps blocking 🤯
Remember there is 2 parts to the video I believe it will work for you buddy doing it on the scan tool only works for a week if your lucky
So if you only drive short distances should you always drive it with high revs ?
Don’t use a diesel for short hops , this is what happened to them ….
Having trouble with my horn and cruise control not working
I assume this is one of the cars that won't get back to the customer - at least, I hope not. What this dodgy mechanic doesn't seem to realise is that while short journeys or bad driving can cause some DPF issues, a badly blocked DPF is almost always hiding another engine issue - injector problems, turbo issues, oil consumption or even just O2 sensors getting on toward end of life causing 'rich' fuel mixture (yes, you can have that on a modern diesel). Ruining the engine like this to try and burn the soot out of the filter won't address the underlying issue - so the car will simply be back again. . .assuming the engine doesn't blow up first after being driven like that.
Jeeeeez bye bye turbo , gaskets ... Engine lol
That's a great way to blow the turbo!
Your test bears no relation to what is going on inside a diesel engine, where the mixture auto ignites.
Actually he was referring to the temperature needing to be up. Direct relationship with cleaning the DPF.
All the emission crap installed on modern engines has made a negitive affect on power output ......
Lots of people take all that crap off then put it back on for the MOT.
Anyone no if injector to def can be cleaned it came up on my tester low reluctant injection
great video, sometimes you have to thrash em.
This is a controversial video but it's a LIKE from me!
I don’t understand how…
I have a high mileage r51 jusy like this one I only use it in the city over the winter months , and it doesn’t get clogged … how bad are people using their cars to bring them to this point ?
My DPF when it starts a Regen this is what happens (1) loads a white smelly smoke (2) My temperature gauge goes to 0 (3)MPG goes down loads and when idling mpg usually sits at 1 but in regen it sits around 9. I have to give it a thrashing in 4th over 2000 revs for around 10 mins then temperature gauge starts going back up to normal running temp I now know its finished.

Eye captain
ORRRR stick some DPF cleaner in the fuel and thrash it down the parkway or motorway that will sort it much quicker than high revving it.
Don't do it, in some cases the dpf cleaners burst the temps so much that you can burn therough the DPF walls or the insides.
Does anyone have a Reader's Digest condensed version?
problem is the steering wheel is on the wrong side
stone cold No it's not, your screen is backwards 😂😂

Not in the Uk or EU by Law.

Lol.... that didn’t show the difference between a Diesel engine and Petrol engine... it just showed the difference in combustion of the two fuels, Diesel engine combust their fuel air mixture by high pressure injection and compression, the petrol engine uses the spark plug to aid in the combustion cycle
Dude u need to change ur test touts to the flat or move garage to top of the hill 2 many roundabouts u never get up too speed that route
Best way to avoid any probs with a dpf...don't buy a vehicle with one! From someone who knows!
Yeah diesels were great till they started adding these things now they are nothing but pains in the wallet and butt
Or take the fucker out ;)
Dpf off egr off stage 2 problem solved
Dont buy a diesel if you are doing short trips on a daily basis..
yep had a few times 307peugot I got rid of it in the end but I've done this what this lad did and sorted 1.5 focus it worked on focus its ag
I guess an EGR clean before this and an oil change after from forcing all the soot and fuel past the rings🤷
Best thing to do with your DPF is delete it, got a 2001, dodge diesel pickup with 5.9 Cummins, never had a single problem with it.
