in the old version of the formula it was presumable
for auto VAG group example regeneration starts when soot level greater than 40%

OK, so what you’re saying is that 255 is the maximum absolute value of DPF saturation (100%), and that regeneration starts well before, around 90 (35%)…

the first version of the formula was approximate
the second option is taken from the scanner

Hello cintakc. I own Zafira MY2017, engine code B20DTH and it seems like those PIDs work for me too. Thanks a lot!
And I’d like to ask you for one more
I think it’s not GM specific, probably SAE as it’s listed in common PIDs in OBDLink where it works. But I did not find it on web. It’s NOx reagent tank level %.

make a log of the exchange program with bluetooth OBDLink

I found this description in OBDLink app report:
Mode 01 – Powertrain Diagnostic Data
SAE 0x85 Support of NOx reagent system data 14
SAE 0x85 Average NOx reagent consumption 0 l/hr
SAE 0x85 Average demanded NOx reagent consumption 0 l/hr
SAE 0x85 NOx reagent tank level 81.96 %
SAE 0x85 Total engine run time while NOx warning mode is
activated 45608 sec

Not sure if this is useful.

I’m a newbie in this topic, so I’ll start asking dumb questions like:

what kind of log do you want and how can I obtain it?

If you create a custom pid for
0185 and test it in the pid editor
while connected, what is your raw hex
response from the vehicle?

(Wiki also suggests this OBD Pid to be
Nox Reagent System related).

If a valid response is received back then
you will need to find the byte(s) of interest.

A*(100/255) single byte example.
((A*256)+B)*(100/65535) two byte example.

Variables A and B are examples only and
will likely be different for you.

Command: 0185
Result for equation: 14

Response:
7E8100C41850E000000
7E82100D10000B228AA

I assume that “D1” is the one I’m looking for, right?
I’m just not low level programmer, so can you explain me how it works? I understand that 01 is some section/query mode of ECU and 0x85 is address and I got 2 10bytes msgs which contains:
– header – ? 07E81 and 07E82
– something – 00 and 10
– data – the rest which is parsed by Torque to A, B, C and D

01 85
41 85 0E 00 00 00 00 D1 00 00 B2 28
0E – “A”
D1 – “F”
B2 – “I”
28 – “J”

if NOx – “D1” so equation (F*100/255) = 81.96%

yes, I got to the same equation, but I want to test it when I get to my car and then I’ll confirm it.

Anyway, thanks a lot guys. And maybe Ian could add those to the standard set of PIDs (or maybe ready for import) in some future release.

It matches your previous report.

Response:
……………………… A…B…C…D
7E8 10 0C 41 85 0E 00 00 00
………… E…F…G…H…I….J
7E8 21 00 D1 00 00 B2 28 AA

7E8 – response to header 7E0
10 – first frame of a multiframe response
21 – subsequent frame
0C – number of data bytes following
41 – response to mode 01
85 – pid of interest
AA – padded to complete frame?

Maybe for the other variables…

A = 0E hex = 0000 1110 binary = 14 decimal
{A:0}
{A:1}
{A:2}
{A:3}
((B*256)+C)*(1/?)
((D*256)+E)*(1/?)
((G*16777216)+(H*65536)+(I*256)+J)

? = unknown scaling factor.

yes! it works!

BTW is there any way how to find out total number of DPF regenerations and completed ones?

Not sure about those. Probably OEM
specific if available at all.

Your raw hex data response for byte A
suggests three of four items are supported.
Will you add the l/hr pids to see if a value
of other than zero can be obtained. This
will aid in calculating the unknown scaling
factor (with a known l/hr value).

I’m guessing that both l/hr equations use
the same scaling factor.

Hopefully Ian will add to an upcoming revision
if these can be figured out.

Hi!

I try to find (for years) some dpf related pids..(SOOT)
Car is astra h 2008 Z17DTR with the f#@$*ing Denso Dece01 Ecu.
I try many pids including your last astra K pids, but no luck…

try PID aa0329, you may need to use atcra5e8

well, i think that this is the best i got till now…I manage to see something raising the same that dpf soot in op-com, its a good start!
Thank you!
You have other interesting pids for Denso Dece01?

Re: Vauxhall (Opel GM) DPF PID

Cintakc,
now , with atcra full start and stop commands (atcra5e8 \n atd1 \n ath1), i get response from aa0329, A or R1 is the dpf soot, but i get the same response from 10,12,18,20,aa0118 and many other pids like 22114b.
All A, B and C bytes are the same for all those pids. This is related to atcra commands I use? What you recomand?

Hi!, my name is Juan. Sorry for my English.

I have an Opel Mokka 1.7 CDTI (1.7DTS) and I can not find anything about the particle filter regeneration PIDS.

I spend many days reading this forum and others and I do not find anything for that engine

Can you help me with the DPF PIDs?

Thank you very much
