DPF Soot level display

[merc07]

@MrGreedy , the app is not mine, it's written by the same guy that did Torque, not much has happened in the past year from him.

It may be that my DPF% PID will only work with the 2012 350 CDI, the DPF, oil, and coolant temps should be standard.

@MrLCA As @m80 suggested, check the OBD2 adapter settings in the Torque app.

I happen to have a 2012 350 CDI, so I might be in luck. I'll download and try with my Torque pro tomorrow and report back

In the Torque app settings you've to choose the BT connection device.

Yup. Done that and it just wont read ecu

I read all this with interested, but i haven't got a clue what you are talking about, i'm lost. But can you tell me if it does a regen if you use cruse all the time? thanks.

If other criteria are met it won't make a difference.
Regen will occur when the ECU wants it to.

I know some have added an LED that activates when the rear screen or mirror heater are on as a warning that a regen is in progress but by then it is a tad late.
Also on my car at least, it's obvious when it is in regen mode.

Mine blew it's oil seals a while back after getting stuck in a continuous regen cycle for over an hour !

I would like to know how far off a regen I am as well as when it is progress and how much longer is it is likely to take.

What we need is a DPF Soot Level display and I have been trying to figure out how to locate the relevant PID modes, codes and calculation.

It is possible using a simple OBD2 can bus controller and processor to stream and save the OBD2 data - figuring out the calculation that Mercedes use is the hard part !

I have managed to figure the soot level data and this morning it got to 100%, started a regen and slowly went back to zero.
The Turbo and DPF temperature values need testing more as I don't think the calculation is quite correct but near enough for the minute.
The temps fly up during a regen.

I will also add mileage since last regen when I get that one figured out as it generally regens at the same intervals..

The regen process happens on a constant cycle above 2000rpm RPM and needs at least 20 to 30 mins to cycle through. Hence why most DPF filters are blocked. You can use DPF Filter cleaner in lambda sensor hole on 2k and over revs then do the 30 minute drive on good revs to activate cleaning process. If you have to stop in that process it should wind down temps pretty quickly anyway as its designed to do that.

Nope.

I don't think mine goes over 2000 revs, if i drop it down a gear it automatically changes it up after 5 seconds. How do you get it high revving, i have tried it by keep dropping it down with the paddles but the auto wants it changing up all the time, and does so.

Hi @merc07 congratulations on figuring out the OBD info needed to display the DPF soot level. Did you reveal the PID(s) and calculation that you ended up with? Apologies if I missed it.

Hi @merc07

Can you add any more detailed instructions on how to set this up in Torque please?

Thank you

 

[merc07]

I would think it only be good for the W204 C350 using the CDI160LS, what vehicle do you have ?

 

[MrGreedy]

w212 e350 cdi 2012 manufacturing year.

Any pointers on how to even start setting up would be appreciated

 

[merc07]

The files are hidden in android...if you know a files manager that allows to show hidden folders let me know !

 

[MrGreedy]

I use root browser on my android phone, which I'm sure does what is needed

See if you can find where the dashboard layouts are saved - tells me .torque/dashboard but not on my phone !

 

[MrGreedy]

So far, all I know is that I need to add one custom PID for each new item I was to display. So one customer PID for Soot content, and then another PID for regen progress.

I'll do some research on this and try and write up something simple so others can hopefully benefit and get soot level displayed on their OM642 350 CDI engines.

 

[merc07]

All you need to do is import the PID using:
Settings/Manage extra PID's/Import file

Import the dashboard using:
Realtime information/layout settings/import layout

I'll figure the file location soon hopefully..

Did a DPF regen wound revs to 2k used Pro spray in air intake then wanged it down motorway in 4th..didnt like DPF spray when cold and egr cleaning seems to be occurring OK some chugging as its clearing all the carbon etc. Also ran with 40 litres and DPF petrol solution to add to the process.

 

[m80]

DPF petrol solution

A typo I assume.

 

[BlackC55]

Just out of interest. Why do you need to know this info?
