Hello,

I want to monitor the degree of charge / regeneration of the particulate filter on an Opel Antara 2014, I tried the options presented on this forum, including the version that works on a Zafira b 2011, but I can not monitor dpf.

I used the standard (default settings) and also the start/stop commands atcra5e8\nath1\natd1/ atcra7e8\nath0\natd0 , pid aa0329, the ATSP6\nATSH7E0\n20 string for the obd adapter

Can anyone guide me on what to do?

Thank you.

dpf load
PID = 223275

minimum value 0
maximum value 100
Formula A

number of Kilometers after the last regeneration
PID = 223277
minimum value 0
maximum value 1000
Formula B*256+C

maybe it is useful for other antara owners

Hi to all and thanks to all participating and sharing details.

I have 1.7CDTI with A17DTR engine and DENSO ECU. Quite happy with the car but it appears to be quite tricky (lack of information) to communicate with all subsystems. it is EURV version.

DPF soot accumulation was of biggest interest to me since I hate to have cleaning cycle interrupted, then it is very useful for me to know how full ECU thinks DPF is. when it is above 87% it can start cleaning depending on driving style. If car thinks you are maybe on open road it can start cleaning at any moment form 87% to latest 94%. In my specific car from Opel Car does not care about fuel level, it will clean no matter what, as long as engine is on operating temperature

Other PIDS are available “pressure, DPF temp, total cycles, distance since last regen etc.” but do not care about them while I am driving, I can use OPCOM”

Maybe only to add DPF regeneration progress, but I can clearly see by EGR status and fuel consumption when cleaning is finished, so it seems pointless.

DPF soot PID in torque:
OBD2 mode and PID:
aa0329

Long name:
DPF soot
Short name:
DPF soot

Minimum value 0.0
Maximum value 100.0

Scale factor:
x1
Unit type:
%

Equation:
A*200/255
OBD Header:
7e0

Diagnostic Start command:
atcra5e8\nath1\natd1
Diagnostic stop command:
atcra7e8\nath0\natd0

No special commands for my OBD2 interface needed.

Refresh rate when accessing this PID goes very low, but for DPF soot accumulation it is OK. so I have it on separate screen. It is not active if I am not specifically scrolling for DPF status.

Hello dear friends!

For z17dtr/denso, someone maybe found pids for injector quantity correction?

I have big problems with poor acceleration at about 2000 rpm in second gear/jerking…

Thanks all!
AND I WANT TO THANK YOU AGAIN CINTACK FOR YOUR HELP SEVERALS YEARS AGO!!

Ok, they work, but i get almost constant value like

injection duration 0,8- 0,9 and timing -63 or 63.
when regeneration starts i get timing 27…

i wish to have injector quantity correcton like 0,65…-0,46 etc…

And i want you to ask what is the difference between
atcra5e8\n atd1\n ath1
and
atcra5e8\nath1\natd1 ??

in my case both works but with huge response delay…

the space in the command ‘\n’ or ‘\n ‘ doesn’t matter
