Excellent video, this is a 'must watch' for anyone who runs a modern diesel vehicle. Unfortunately, most people only start to look into the challenges of having a DPF once they have suffered a major issue. (myself included)
Thanks a lot for your comment! We are very glad that you like our video and hope to see you in our channel again.
Have a great day!

ha, Thats exactly why I'm here!! Learned something new as well.
so the option is put 30 litres of fuel in every 2 weeks and burn it off on motorway ,even though you have no need to go on the motorway.
Just costs people more money for fuel and replacement parts ,this is a horrible idea we live with costs a fortune to run a diesel now
Why the annoying music
Lol
Don't buy diesel car
I looked up a DPF (just the filter itself) online - $2,100.00 😡
Here in the states we are seeing the medium duty diesel being replaced by the ford 7.3 and other big gas engines because when the diesel breaks down it’s always thousands
Perfectly explained 👍💪👏
Thank you for your kind comment, Miros! :)

Heres a couple of DPF tips use low ash oil, not any old supermarket shite or garage oil sold by the barrel by mechanics, it's cheap, and has a high ash content also , dpf cleaner additives in the tank and occasional high quality diesel helps keep the system clean as diesel isnt as good as it once was , take highway journey at 70mph or 100km an hour in fourth gear keep it there at a constant RPM try not to adjust the speed for 30/40 mins at a consistent speed to help passive regen happen.
Hello!
You're absolutely right about the importance of using the appropriate oil; it's crucial for maintaining the optimal performance of your Diesel Particulate Filter (DPF). Car manufacturers rigorously test their engines with a specific type of oil to ensure flawless operation. This oil contains the precise balance of phosphorus and other additives, making it the ideal choice for your vehicle. This is precisely why Walker strongly advises consistently using the oil type and brand recommended by the manufacturer.
Moreover, the quality of the fuel you choose also significantly impacts the level of soot accumulation in your DPF. Opting for low-quality fuel can significantly reduce the lifespan of your filter.
To ensure proper DPF regeneration, Walker recommends driving your car at speeds exceeding 80 km/h for at least 15-20 minutes twice a week. This practice effectively cleans out the filter and helps prevent future issues.
Have a nice day!

All great ways to invest more $$ in an unnecessary system.
Great video, but doing some research on cerium oxide fuel additives, it seems like they have been stopped because the health effects of it's emission, being higher than the benefits of it's effect on combustion.
Hi Ignasi, Thanks for your comment. You are right about the fact the cerium oxide has been little by little reduced from the DPF additives replacing it with Iron based additives in the new compounds, this was also due to the fact that cerium oxides produced mineral deposits in the DPF honeycomb reducing the lifetime of the DPF. As you could see the old model where lasting around 80.000Km and nowadays the newer models lifetime of a DPF is way over 250.000Km.
Have a nice day!
Good video, thank you for your info and these opened my eyes on it.
I've tired to use some of additive products for my OM651 diesel engines to clear some soot and prevent any issue from DPF.
Added additive (add 1 of 2-3 time of refill full tank) to the tank and full fill the fuel tank and run it's look smooth.
But sometime I was found green sticky liquid 1-2 drop at the exhaust pipe (located on back passenger) that remind me it's look like 4:47 of your video.
After found this green liquid and run the car until 1/4 of the tank then re-fill it without additive, this green drop disappear.
Not sure I use the correct way to save my DPF? Or this green liquids are the problems of my DPF?
I use short run (5-10 km) in the morning < that may product soot.
But every month I drive the car to travel around 150+150 km (go and back) on the highway every month and drive on the highway 60 km once a week.
Hello!
To maintain a DPF in optimal condition, especially considering frequent short trips, it's advisable to drive approximately 60km continuously once a week and make a longer trip of around 150km each way (300km round trip) once a month, preferably on the highway with minimal traffic or congestion. This approach is sufficient to preserve the DPF throughout its lifespan, assuming the vehicle is operating smoothly and receives regular maintenance.
Using specific additives designed for DPF maintenance can be beneficial if used sparingly and only if they don't contain substances that could harm other parts of the exhaust system or engine. It's prudent to consider additives when the DPF's lifespan is nearing its end, aiming to extend its functionality, provided the vehicle is otherwise in good condition and any issues are isolated to the DPF.
In essence, a well-maintained vehicle with a healthy DPF and the described driving routine typically doesn't require additional assistance to uphold its performance.
Thanks for following us!

Great video thank you
My gripe is that many manufacturers forgot to allow operator commanded regens. My vehicle, all it did all day, was regen. Then for some reason it wasn’t. Threw a code requiring a regen, but I couldn’t force it to do one, only when I went into OBD could I attempt one, by which time it needed a new filter. Manufacturer ate the cost of that one.
Hello!
Thank you for sharing your experience with your vehicle. It's unfortunate that you've had to deal with this issue, but I appreciate you taking the time to provide feedback. It's worth noting that the process of forcing regeneration from autodiagnostic equipment can be tricky at times, so it's understandable that you may have encountered some difficulties. Once again, thank you for sharing your comment.

It's a more general problem. They don't show error codes to users or allow actuator controls to debug problems. You have to buy expensive scan tools.
Cars really should have that stuff built in. It's basically locked behind software there's no reason to not have it.
Once those sensors are clogged or vaporizer is you can forget a forced or passive regen system needs cleaning out first on or off also need to do a system health checks first before anything there are values in pressure that need to be taken into consideration sometimes dpf is blamed but issues can lie in other places causing it the root problem
At 10:56 its stated in the picture aside from egr, injectors that the BCU is needed to activate the "rear window heater" why?!
Thank you for your inquiry. To initiate the regeneration process of the diesel particulate filter (DPF), a minimum exhaust gas temperature of around 380°C-400°C is required at the DPF catalytic converter inlet. Some vehicle manufacturers, such as those in the PSA group (Peugeot, Citroën, etc.), employ a method where the engine is put under load by activating the car's electrical systems (rear window heater, rear-view mirror heater, etc.). This increases the exhaust gas outlet temperature from the combustion chamber, ensuring the necessary temperature for regeneration.
It's crucial to refer to the vehicle's service manual to identify which specific electrical systems are essential for regeneration to occur. If the filter is clogged and periodic regeneration is not taking place, it's possible that one of these systems may be damaged and require repair for normal DPF regeneration to resume.
Have a nice day!

So my car, a 2012 Peugeot, has a dpf and cat converter, no adblue system, and the tailpipe is spotless and I've hardly ever seen any smoke even upon start up.
Conversely, my work vehicle is a 2017 Peugeot (again with dpf, cat but with adblue) and the tailpipe is like a typical 'old" diesel - very sooty. How would this be so??
Thank you for your inquiry. The issue you've described could potentially have various underlying causes. These include the formation of ring cracks, which can result from temperature fluctuations during the regeneration process, especially when it's interrupted abruptly. Cracks in the DPF monolith may also occur due to impacts with objects on the road or during transportation. Additionally, uncontrolled expansion during forced DPF regeneration cycles can contribute to the problem. In some instances, a malfunctioning fixation mat may allow burnt gases to circulate around the DPF housing without proper filtration. To pinpoint the precise cause, a comprehensive X-ray analysis is recommended.
Have a nice day!

@@GarageGurusEU could be alot of things ,glow plugs ,injectors ,map.maf sensors .blocked pipes ...its an endless list of trials if it doesn't show up on reader....on some vans they wont regen if the temp senor in the wing mirror is faulty ,,absolute joke...
Does UNIT WITH DPF
CONNT BE TUNE OR REMAP?
It is possible that EGR work incorrectly and i have dpf error?
Hello!
EGR system failures can permit increased amounts of burnt gases into the combustion chamber, harming the mixture and leading to more solid particle accumulation in the particulate filter. If combined with frequent city driving, this can trigger DPF errors.
Hope you find our answer useful.

Love all the Walker facilities in China. I wonder if DPF systems mandatory there? 🤔
Hi!
Presently, China adheres to the China 6b regulation, mirroring Euro 6 standards. However, with the introduction of China 5 in 2017 and China 6a in 2020, particle emissions levels now align with European Euro 6 standards, which are currently in effect.

I now know why my bus fluxuates in power
The process goes unnoticed by the driver. Biggest lie I heard this month :D
Thank you for your feedback. Regarding the Diesel Particulate Filter (DPF). The DPF undergoes two regeneration processes. The first type is known as continuous regeneration, which occurs consistently when the filter's temperature ranges between 270°C and 450°C. This process is highly effective as it burns more particles than the filter can store. It is completely inconspicuous to the driver as no adjustments are required to the engine parameters. If the vehicle maintains this temperature range at the DPF, typically while driving on highways or intercity roads, the filter will remain mostly clean, eliminating the need for additional forced regeneration cycles. However, as a precautionary measure, the system performs a safety forced regeneration approximately every 1,800 kilometres to ensure the filter's cleanliness. Since the filter is already clean, this safety regeneration is usually brief.
On the other hand, if the vehicle primarily operates in city or congested road conditions, forced regeneration may occur at intervals ranging from 400 to 800 kilometres, or even shorter. This second type of regeneration involves specific engine processes such as post injections and the activation of electric resistances. These actions increase the temperature of the gases that reach the DPF filter up to 500°C. In non-additivated models, this regeneration process typically takes between 10 and 16 minutes, while in additive-assisted models, it lasts between 6 and 10 minutes. It is worth noting that this type of regeneration is easily detectable if the driver reduces the engine's revolutions or stops it due to the involved processes.

video cũng hay đấy chứ
Cảm ơn rất nhiều! :)
Chúc một ngày tốt lành!
Great video but every car I buy these are the first things I remove. Car drives so much better, more HP and better fuel consumption
Thank you for your comment. Currently, these systems are integrated as standard, meaning that the engine design has been optimized to accommodate a certain level of backlash. Consequently, the valve crossover has been adjusted accordingly. Eliminating this system would result in a loss of backpressure, leading to incorrect valve operation. This, in turn, causes valves to remain open longer than necessary, resulting in increased noise, consumption, and power loss due to wasted fuel. Moreover, under current European Union regulations, removing these systems is entirely illegal and can incur severe fines for any workshop engaging in such activity. It's worth noting that these systems function efficiently and trouble-free when used according to the manufacturer's guidelines.

Yet another questionable cost and complication enforced by the EU to push up vehicle costs and make them less affordable.
That’s why trucks need APU
stop idling your truck
Try investing in Apu for longer DPF system life 😂
Just ask the question
WHY DO THEY MAKE THE SOOT PARTICALS IN TH FIRST PLACE
AS A DIESEL FITTER I KNOW DO YOU
E G R HINT
Could you please reformulate your question so we can give a proper answer? What did you mean?
Thank you.
@@GarageGurusEU my question is simple
WHAT CAUSES A DIESEL ENGINE TO MAKE SOOT
Improvement In injection pressure, spray pattern, IE common rail including electronically timed and fired injection, and compression ratio have made these engine's perform WITHOUT SOOT UNTIL YOU ADD THE EGR CIRCUIT
@@garreysellars5525Nox. To get complete combustion you need high combustion temperatures. But this causes Nox gas to be generated. So a small amount of exhaust gas is fed to the inlet manifold which reduces the temperatures but this makes soot.
On a still day, Nox sits at about pushchair height, so adults don't breath too much in whereas their offspring do.
Basically a diesel engine is great if you like polishing a turd. After all the filters and treatments plus the extra fuel used for regeneration, the overall efficiency comes close to petrol.
@@yodab.at1746
So we spend on teck to make engine's efficient
IE turbo. Intercooler to improve air density and then we stuff that up by adding Hot air defeating the original purpose
Try adding water methanol injection to intake to reduce combustion temp
Works for me exhaust temp dropped significantly
It how I protect my turbo on heavy pull when loaded
@@garreysellars5525 water injection was pioneered in aviation a long time ago to increase charge density at high altitude. Also to stop detonation under heavy loads.
Are we a slave to our cars with this DPF having to drive a certain way to keep up the regen
Process or will cost thousands if they go wrong 👎
We never voted for the EPA

What a stupid system. So all the rubbish is ejected out anyway albeit periodically like a full bin whilst risking disabling the car when it could just go out as it was meant to instead of unnecessary dorced motorway journeys to clear it out.
Wrecks engine's, useless just like egr valve and dual mass flywheels modern engine's are so unreliable.
Dont buy a Volkswagen diesel. Because it costs thousands when these crap out.even to clean them out is 1grand. Make sure when your buying a car that there easily accessible or you will be paying lots of money cuz they always need cleaned out constantly..
All Diesel cars are shite .spread the word .
seems like a poorly designed system, so many cars getting scrapped early and wasted £££ trying to solve dpf related problems. in hindsight and simple cartridge or detachable block which would be replaced every 6 months would have been better. or better we didnt believe the "expert's" at the start and stayed with petrol
I'm sorry the animated guy is so unnecessary
Thanks for your comment. Anyway, we hope you find the content useful.

Where does all that DPF waste end up after regeneration + all the chemicals used for it
Hello!
Thank you for your inquiry. In modern diesel vehicles, the Diesel Particulate Filter (DPF) plays a crucial role in eliminating soot generated during diesel combustion. The process of regeneration is responsible for incinerating these particles, transforming them primarily into harmless CO2 and water vapor. These byproducts are then expelled through the exhaust system. Post-regeneration, what remains within the filter is mainly ash, which originates from engine oil and fuel additives. Gradually, this ash accumulates, eventually necessitating either cleaning or replacement of the filter.
In essence, following the regeneration process, the majority of combustion residues are emitted as CO2 (the same gas we exhale when we breathe) and water vapor. Nonetheless, a portion of ash does remain within the filter. Additionally, certain manufacturers, such as PSA Group (Citroën, Peugeot), utilize fuel-borne additives to optimize DPF regeneration. Initially formulated with Ceria oxide and later with iron oxide, these additives are introduced into the fuel tank during refueling. They facilitate quicker and more efficient regeneration at temperatures around 100ºC, thereby conserving fuel. However, over time, these additives can increase the accumulation of soot due to the presence of Ceria and iron residues. As time passes, these residues may obstruct the filter, making periodic replacement of the unit essential to prevent significant issues arising from excessive exhaust backpressure. These issues include heightened fuel consumption, reduced power output, and the potential for damage to other engine components.
Hope it is clear now,
Have a nice day!
