Dpf cleaning The difference between soot and ash

A quick video of my own van a 2012 Vivaro which had some pressure on the dpf .
Cleaning carbon and soot is one thing cleaning ash is very different and identifying the difference and fully understanding them both is key to getting it right and doing the correct clean to give the best service and doing the best job without call backs . Ash can not be cleaned on the vehicle.
For those of you who follow the page on Facebook you will remember how taking Kayla my teenage daughter back to Devon some months ago half way we found ourselves in limp mode due to oil did fault . This was 100% my own fault and a rookie error as I forgot to tell the ECU I had done an oil change myself .
This in turn stopped the dpf from being able to regenerate causing the dpf to block.
Once in Devon I carried out an on car dpf clean due to the pressure being off the scale and at 10pm I wanted to get home yet a week later I was forced to remove the dpf and get it flashed cleaned to remove the Ash build up .
Since then I've had no problems and was only by chance I was sat waiting and decided to check the van and managed to carry out a forced regeneration before any lights came on.

Quick question. If the DPF pressure gets high like 25mbar at idle when it should be at 1-7mbar, would that cause the ECU to correct the injection deviation?
My Injection quantities at cyl 1 and 4 were deviating quite a lot before a forced regen but after the regen they almost stopped doing that and started matching cylinder 2 and 3

Depending on what car some use post combus regen so injectors can be affected but as long as the pressure dropped below 10 millibar after regen then all should be back to normal .

Mine shows 0 and on heavy acceleration 37 and my dpf regenerate every 120-130 miles regularly, where could be a problem (galaxy 2012 2.2 200HP) no errors etc, temperature go to 640-655 C

It's doing a regeneration twice as much as it should without looking its hard to say what's wrong but what are the readings in ? Kpa would show it as blocked and more then likely with ash .

[@songoku7915]

Maybe it needs washing the ash and then resetting it in a diagnostic. Did you finally solve your problem? My Yaris D4D Euro 5 regenerates every 120 km (it has 182.000 km) and i think it is due to the ash accumulation over time...

Hi, after reading your description about not telling ECU about oil change, was this just a case of you not reseting the service interval in VCDS or something a bit deeper in the software? I'm asking because I'm about to do oil change myself and don't wan't to run into the same issue.... many thanks in adavance, excellant video btw

[@dpfcleaningltd2816]

Oil reset can be done by diagnostic tool like vcds or via dash on some cars . Always needs to be told its had an oil change

Hi. My Toyota Yaris D4D Euro 5 regenerates every 120 km (it has 182.000 km) and i think it is due to the ash accumulation over time... Do you think professionally washing it and then resetting it would solve my problem?

[@dpfcleaningltd2816]

Without looking at it myself I cant confirm but removing the ash would be first step without correct diagnostic being run.

@@dpfcleaningltd2816 Thanks, that's the same my mechanic told me. We will put this in the cleaning machine and it will show us if it's cleanable...

My ash volume is reading 0.11L, is this healthy or not? Thanks

[@dpfcleaningltd2816]

All Ash and soot readings are guess work via the ecu as a rule pressure should be under 10 millibar at idle . Once a regeneration has taken place check the pressure and it will show how much Ash higher the pressure the more Ash you have .

Do you do “ash cleaning”? My car needs the ash cleaned out

[@dpfcleaningltd2816]

Yes only way to remove ash is to remmove the dpf and flash clean

Hi I got a 2014 bmw 320d ash at 41% how can I get it cleaned on the car soot at 5%

[@dpfcleaningltd2816]

You cant ash cant be cleaned on the car . Unless the car has 200k plus I would not worrie about it bmw dont suffer with ash.

[@liverpool45879]

@@dpfcleaningltd2816 it’s at 84k miles so you think it’s ok

[@dpfcleaningltd2816]

@@liverpool45879 With regard to Ash yes should be fine however I cant confirm if you have a fault or build up of soot without looking at it .
