Just got myself a new Ross-Tech Cable. Should arrive next week.
So I may be able to investigate the Soot levels Pids.
Is anybody knows where to look for them in vcds?
Thanks

Go to Engine/Advanced Measuring values! Type *soot* into the text field.
The auto filter will search it out.

Maybe you will find this useful.
I've found some info regarding mode $06 in the J1699_3_201707 standard and in the J1979DA_201702 Appendix.
This is how the respond message look like in case of a $06 request:

The MIDs, “Unit and Scaling” definitions can be found in the J1979DA_201702 Appendix.
For ex:

(reminder: after B2C5 in the 06B2 respond 0x36 is the unit code, then come the measured value, min limit, max limit, each 2 bites long)

So I downloaded the VW.csv from this thread

https://forums.tdiclub.com/showthread.php?t=404334

And Torque Pro is reading 49-50g, guessing that isn't accurate?

Any of these settings I should modify?

I use VagDpf and my regens start when there is approx. 24 grams of soot and runs until it burns off to 4 or 6 grams. Something seems amiss.

Hi everyone,
My name is Chris and I'm new here
but let's cut to the chase...

I have studied this topic thoroughly and I have notice that tere is no new cars(past 2018) involve it the discussion, so I've decided to put my two cents worth in here.

I have Skoda Octavia 2019 (MY2020) 2.0 TDI 150PS MT DFFA with SCR aftertreatment (AdBlue), so the same engine as in Golf or Passat.

From the beginning I was planning to integrate the Torque app with this car but it seems that is will not be ass straightforward as should be.

What I know so far:
1. Almost all commands from the standard OBD PID list (https://en.wikipedia.org/wiki/OBD-II_PIDs), which are related to DPF, does not work.

017A - no responce
017B - no responce
017C - no responce
018b - no responce

06b2 -
0: 46B2C9FC004B
1: 800001C2000000

Unfortunately after a 30km of driving there where no changes in 06b2 respons. Maybe there will be change while the DPF will regenerate but I have to wait to test it.

2. Vag DPF shows DPF info. So as OBDeleven.
3. Both above mentioned apk shows 3 values of the DPF saturation of soot.
The procent value changes from (in my car) 22%(the min value I ever achieve) to 100% ( I tried to block regeneration using OBDeleven but no luck).
The calculated soot mass (in grams) form 6 to 24g.
The measured soot mass (in grams) form -9.99g to 22g.

Both The procent value and calculated soot mass are an indicators only calculated by the ECU and there is no stiff relationship to the real soot value in DPF. It can be nicely seen comparing min value of measured soot mass ( which is a real soot mass) just after the regeneration process has finished. In most cased the value is different and varies between -9.99g and -5g.

As we know we can force the ECU to regenerate during driving. When we do that both procent value and calculated soot mass goes to its max values (100 and 24) and the regeneration process starts, even that the measured soot mass is -5g. The regeneration time in that case is a bit shorter but not much. Both procent value and calculated soot mass is slowly decreasing even that the real measured soot mass can't go below -10g.

4. I came across the PID list from ScanGage.com: https://www.scangauge.com/support/x-...ds/volkswagen/
I do not understand the TXD values. How to decode it to the Torque language? I will work on that, stay tuned. Very interesting information.

5. I have noticed that one of the standard (bulid-in) PIDs in Torque is showing a EGT value which is displayed in VAG DPF.
-Exhaust gas temp Bank 1 Sensor 3 (pid ff1283) - DPF Input Gas Temp.
-Exhaust gas temp Bank 1 Sensor 4 (pid ff1284) - DPF Output Gas Temp.

6. Since VAG DPF is working ok those data are there for sure. So I will try to get info of the PID using Bluetooth HCI snoop log but I have to get different phone. Stay tuned.

The news...
I have a list of commands send by VagDPF.
They should be in that order but I still need some test. I have marked RED those PID's that I identified for 100%. The list will be updated soon. Stay tuned.
Soot mass calculated:
- send: 222609
- received: 7E8 05 622609 05CA
{05CA- 1482[mg] (14,82g)}
Regeneration duration:
- send: 221AC0
- received: 7E8037F2278
7E805621AC00000
Distance since last end of regeneration:
- send: 221ABA
- received: 7E8037F2278
7E805621ABA0690
{0690 - 1680*100= 168000m=168,0km}

Time since last regeneration:
- send: 221AC3
- received: 7E8037F2278
7E805621AC307DE
Oil ash residue (g)
- send: 221ABD

Pressure before or after dpf
- send: 2216A9
- received: 7E8076216A900000D18
And now....
I really don't know how to put those commands in the Torque.
When OBD header field is empty all those commands give NO RESPONS.
When heder is set to auto some crazy sh*** happens.
For example:
send: 221ac0
response: 7F2278
621AC00000
Have no idee what kind respons is that. Torque does not recognize the A,B,C... byte so no equation can be made to have some reasonable output data.
I can also provide full init command set for the ELM327 made by VagDPF.
Any help would be appreciated.

Here's some of the formulas (see below) I already and can use on Android Auto via OBD2AA app, which uses the data read through the Torque app. Copy and paste the file into a text file and then convert it to a CSV file using Excel using space as a delimiter and it should convert properly. I mostly compiled this through this forum as I believe someone posted most of these values and others added additional values when they were found. As to the data you're receiving, I have no idea, but I would definitely be interested in converting the regen duration since that gives me an idea how much longer until the regen ends.

Thanks for that info. Unfortunately most of those PID's does not work in my car. I will test that later on other few other cars.
I also have OBD2AA and it works great on new cars except the fact that it is still using Torque.
I'm able to test almost any configuration on following cars:
Skoda Raid 1.6 TDI 90ps MY2014
Skoda Octavia 1.6 TDI 105PS MY2016
Skoda Octavia 1.6 TDI 110PS MY 2017
Skoda Octavia 1.6 TDI 115PS MY 2018
Skoda Octavia 1.6 TDI 115PS SCR MY 2019
Skoda Octavia 2.0 TDI 150PS SCR MY 2020

On all of those cars Vag DPF is working flawlessly.
I will test Torque and my debugged commands using Serial Bluetooth Terminal. It should give more consistent results.

VagDPF communicates on the CAN bus from my reading. I don't think Torque and Vag DPF commands are compatible.

Definitely Torque is not straightforward compatible.
Command 222609 (Calculated soot mass) gives strange response. I have to talk with the creator of the Torque. He should make this app compatible with the new cars, because now it is not.
I will post that info later but major problem is that Torque does not detect bytes so there is a problem with interpretation of the results. So far I will mark the 100% results with the proper function on my last post.

THANK YOU Wacholek
today I used your method (Bluetooth HCI snoop log) on my 2013 GOLF 7 1.6 TDI CLHA engine and my PIDs:
Soot mass calculated:
- send: 22114F
- received: 7E8 05 62 11 4F 06 2B
- formula: ((F*256)+G)/100

- send: 22178C
- received: 7E8 05 62 17 8C 00 87
- formula: G/10
- result :13.5gr

note:I used formulas for arduino project I don't know about "Torque"

@fkoca5055
Where did you get those requests? 22114F, 22178C.
I think I will also work with arduino. It has no limits compering to Torque. At least until I will talk to its creator.
Probably you already have the basic knowledge about the ELM327, but this is nice info for start:
