The company I work for has just had a Ford Courier van's DPF cleaned after the van went into limp, mainly due to it being used for short journeys. The mechanic told me that a regen involves over-supplying diesel, some of which washes down the bores, contaminating the engine oil. The oil level might even rise! He recommends _much_ more regular oil changes, because of this. I like the idea (from another comment) of opening the DPF chamber, throwing away the contents and welding it back up!

It does add a pile of complexity that make one want to return to the days of simple electromechanical vehicles. The easiest way to simplify things again now is move to an electric motor. You don't need all that anti-pollution kit because there isn't any in the first place. OK, you don't get 700 miles per tank, but you do get clean and quiet (and significantly cheaper motoring if you can charge at home). Seems a reasonable tradeoff.

a thought Mel, as I wish to remove my DPF ...my idea is to remove the exhaust like yours, then cut a hole through the ceramic to put a straight pipe through, welded to each end.

Some medical authorities are now saying that the much finer particles ftom the DPF are more easily absorbed into the lungs than the relatively harmless but smelly pre Dpf ones ever were .😊

[@nkakaputa9293]

All this off vehicle DPF cleaning and DPF filter blockage can be avoided completely if the DPF self regeneration process took place as the vehicle system saw necessary. However if your fuel gauge is always below 1/4 level , the ECU will NOT kick in the self regeneration process….ending with a filter so blocked that forced regeneration with diagnostic tool or self regeneration becomes ineffective.

[@BigVanSmallWorld]

Interesting that thank you 🙏

[@donner101]

Hi by self regeneration do you mean just driving the van until it clears out itself?

[@nkakaputa9293]

@donner101 Yes sir. As long as the DPF has not been left to point of blockage the system will periodically self clean.... the ECU looks at the fuel level to commence this process. Because of the extra fuel required to achieve the high temperatures.

[@johnpatterson5744]

Yes the pressure within the DPF should be no higher than 10 mbar.and ensuring your running the level of diesel in the tank no lower than a quarter full,preferably at least half full ensures the DPF will function effectively.👍

Some vehicles wont do a self regeneration if the ambient temp sensor is faulty or if the vaporiser is blocked in the exhaust, this is where fuel is squirted into the system to burn off the soot.

There are several reasons why there are companies that clean filters. 1. they use hot liquid for washing. 2 they recycle the liquid. 3 their cleaning liquid is filtered and the waste is disposed of correctly. 4 there is a guarantee on their work. Not like your solution, where chemical liquid and particles run directly onto the ground and contribute to contaminating the groundwater.

[@dmcarpman]

i had problems with me last kuga had to remove the dpf to clean it. did clean it before via dpf pressure sensor tube this worked just as well as the removal watching the pressure drop on my forscan system. then doing DPF rest the values. the biggest problem is people don't investigate correctly as to why the DPF regen is not working in the first place to keep it clean. Mel this could be to the fact that your DPF pressure sensor is faulty. also make sure that your sensor when you get fits in place and goes as deep into the exhaust as the original or you could get incorrect readings. that sensor works like a 02 sensor it needs exhaust flow over it hence the holes in it.

Cleaning a dpf while in place is often a cheaper and easier option due to the location of the dpf and due to exhaust sections being seized together. But, it does not clean as well as removing the dpf and back flushing to clean it.

[@BigVanSmallWorld]

Yeah I know

[@schmiddy8433]

The main reason the contaminants dont flow through the filter is because the particle size is too big. by using a solvent the dissolved contaminants can become smaller than the filter can hold and it will exit, so those on-car cleaning methods *can* work, but taking it off and cleaning in both directions is by far the best way.

[@merlin1346]

In theory your right, in actual fact you are incorrect. Wet cleaning is just as effective from the 'inlet' end of the DPF especially if the DPF is near vertical such as a Mercedes S class. One other point, is the heat sensor going to be at the right depth into the gas flow...

[@danny6574]

@BigVansmallWorld Your reasoning for taking off the dpf to be cleaned is flawed. The dpf captures the bigger particles created at lower temperatures when the engine is cold. Then burns them off during the regen allowing them to passthrough the filter. Blowing a cleaning solution into the dpf dissolves the soot into small enough particles allowing it to passthrough the filter.

You really need to put a warning on this video about the hazard of using the cleaner and your consequences, as others may go ahead without realising the dangers.

[@updatename6637]

1/4 pool acid 37%- will do the job as well :)))) I think you broke not heat sensor, this is particular matter sensor- it reads pressure and sends info to computer. This is how you find out that dpf is blocked.

[@Costa_del_Artlepool]

Well aren't we all looking great in our suspenders

[@logancomfort4332]

Might have just been easier to buy a new bung for the sensor and just weld that in

[@BigVanSmallWorld]

Yeah but I couldn’t get one

How would you unblock a sink?

[@patrickpirelli7897]

I vrone down up scotland blocked DPF so ordered a reconed one from DPF clean team down Lester £750 😱 causw of the blocked DPF was a machanic fitting a cheap sensor and couldnt delete the engine management light which wouldnt allow the DPF to regenerate. Cost me a thousand pound in total and ruined trip.

[@thebrowns5337]

how does a DPF get blocked on a camper? we use a camper for holidays, weekends or even day trips - usually all long(ish) journies including motorways or dual carriageways. Never had an issue with DPF.

[@BigVanSmallWorld]

Good question!

[@jondor654]

Nice logic

[@dannylafreniere566]

why don't do a manual regen with a scanner.?

How many liters of the Wynn’s DPF Cleaner was needed to fill your DPF? What year is your Sprinter?

[@BigVanSmallWorld]

All of it

[@MartinJG100]

Interesting. Good impersonation of Sid Snot by the way :).

[@BigVanSmallWorld]

Haha I’m going to have to watch this back now 👍😂🤣👍

[@john-ec6sy]

great logic and engineering. hope it all works ok. i wouldnt be suprised though if the sensor is M14 X 1.5 and the standard M14 bolt you fitted is a X 2.0mm pitch thread.

[@jonpeddel9616]

If you were just going to use water to rinse it, i wouldn't have bothered with the treatment solution. Best way to clean these is heat and airflow, just like it would get on the vehicle.

[@BigVanSmallWorld]

Thank you for the advice

[@patkelly9907]

Im not a fan off DPF how ever they there for a reason and work reasonable well untill the mileage get to around 100.000 mile then we all have problems However in my experience the dpf is blocked by oil coming from the crankcase breather filter which is blocked As the soot and ash build up then you add engine oil fumes you have a real stick mess inside your dpf Check inside intercooler pipe make sure it bone dry if not you will soon block the DPF

[@BigVanSmallWorld]

That is probably the most helpful comment I’ve had on here thank you 🙏

[@Andrew-ki5jz]

Just my point out to all wingers is it not much safer what you did by flushing it out into the drainage that goes to a water treatment center and removes harmful toxins substances,that people on your site people wingging about environmental rather than pumped into the air, airborne for possibility days until it's breathed in by some poor basket causing lung cancer

[@shamskl3245]

wow Great job yang man well done 😀👌

[@BigVanSmallWorld]

Thanks 😁

[@smifff63]

My Karcher make the same noise as yours when trigger not squeezed.

[@BigVanSmallWorld]

Interesting 🤔

[@smifff63]

It’s not normal, I’ve had mine about 20yrs and it started doing it last yr, it pulsates like yours, no idea why.

[@jondor654]

Possibly one or more broken springs on plungers . If so can be replaced as I did for a clone. Fiddly but extends useable life aka eco friendly

[@smifff63]

@@jondor654 Thanks.

[@tuatua9029]

great demo.....instead of the soot going to the atmosphere as you drive.....flushing down the drain in one go.......defeats the whole object of reducing emissions......so whats the point of dpf's

[@BigVanSmallWorld]

I have absolutely no idea 🤷‍♂️ they are just a pain in ass and a waste of time as most people are just cutting them out and re mapping there ecu

[@matthewharmer1656]

Why not cut the broken bit off completely and the manufacture a new bit then weld it on?

[@BigVanSmallWorld]

I did something like that

[@davidlennard2729]

If the DPF is blocked will it stop the engine from starting??

No I don’t think so but it definitely affects the performance

[@Rickym403]

Great work Mel 👍

[@BigVanSmallWorld]

Thank you 😁

[@ln8605]

Are you going to tell us the dpf is still showing a problem and actually it was the exhaust back pressure sensor (£45)?

[@BigVanSmallWorld]

No not at all it’s actually working fantastic now I have cleaned it and reset the ECU

[@sccsuk]

Just back flush it with water using jet wash then take it for a run and let it regen properly

[@BigVanSmallWorld]

Yeah 👍

[@nathanhuitson1418]

Did you have to plug the holes mate to let it soak overnight?

[@sabiya2]

Great video mate, just a quick one would I able to undo that nut on the pipe that connects to the exhaust that holds the thin pipe? Access on mine is very limited, I can only access that nut with that thin long pipe. Was thinking undoing it and spraying cleaner inside it.

[@BigVanSmallWorld]

Yes, absolutely

[@terryjones2012]

Sensor will give a false reading as it needs to sit in the middle of the pipe

[@BigVanSmallWorld]

Well it’s still working

[@garyradley5694]

Wynns. Great Australian car products.

[@einfelder8262]

Your assertion that cleaning a DPF in the flow direction would not succeed is completely wrong. You example using a paper vac filter is nonsense, since the particles in the DPF are all soluble and the honeycomb holes through the length of it are all the same size, easily allowing dissolved material to flow through. However, pouring cleaning fluid into a horizontal DPF can only clean the lower approx 40% of the blockage, so removing it for cleaning is a good idea because you can dissolve 100% of the material. In some vehicles removal is pretty easy, but in many others it is an almost impossible nightmare.

[@giogio4833]

Never mind the dpf how did you manage to sharpen the drill bit on that wheel.never works for me. 😂

[@BigVanSmallWorld]

Years of practice 😊👍🍻

[@Gazza-zg2tr]

Hi Mel have you tried just putting petrol mixed into the diesel makes the engine run bit hotter but clears the DPF my truck fitter gave me the idea and it worked put about one gallon of petrol into a full tank of diesel .worked on my Renault Master van?

This could seriously damage your fuel pump I wouldn’t recommend doing that
