Alvis, so far I've observed a sudden run-up in soot mass only once. In general, regeneration has become more irregular since the fix. The car is not waiting for the computed value to reach 23 gram most of the time.
740, that looks like it should work. Zaphod has a 2013 Canadian Passat, and on my 2012 US Sportwagon those addresses are correct as well.

prefect I'll give it a try.

Has anyone figured out the PID for soot mass calculated?

Do you mean the PID or the equation? Pretty sure the generally accepted PID used in Torque Pro is 06b2. There are at least five variations of the equation in the "Reading Soot Level With Torque" thread and I have tried the same two you did with similar results, waiting for time to try the newer equations mentioned in posts #57 and #59. http://forums.tdiclub.com/showthread.php?t=464119&page=4 There is another thread out there that I cannot find at the moment where I found PIDS and equations to make a % gauge and a REGEN ON/OFF gauge. I tried them and they are right on the money, just today my % reached 100 and the REGEN ON/OFF (0/1) switched to "ON" (1) and my EGTs confirmed that a regen had just started. I don't see how the % gauge can be anything other than calculated soot mass because from my understanding that is the number that almost always starts a regen. They are very handy because now I only have to have 2 gauges and I know exactly when the regen will come.
I can't find that thread right now but as I recall it was started by diesl.

Yeah I have those equations. I'm looking for soot mass calculated so I can tell how much longer the regen will last. I just need any equation that lets me know that.

OK I didn't even know it was possible to watch calculated soot mass reduce in real time

So on our phase 1 emission fixed '15 Passat, the Soot showed it was a green good PID (when selecting the value to display from active PIDs) but the value it displayed in the gauge was blank.

Does phase 1 vs 2 make a difference in the calculation?

Both of mine show blank too in Torque. Not sure how these have to be set up. Anyone have a pic of how the custom pids are set up?

What epa fix do you have phase 1 or phase 2?

This app does everything you want, uses the same hardware as the Torque app, and it's also available in a free version

Doesn't work for all models. I have it working for some of my modules (CVCA) but not all. Been in contact with the owner over seas but he isn't interested in doing much to modify for the US cars due to special equipment needed he says to take readings he needs. Maybe some of you "hardcore" guys with equipment could help him out. I tried with VCDS and he said it isn't the right tool for the job. You can/may be able to get some to work by trying different models.

Hi!
Would you share a screenshot of 06B2 Test from Torque?
I have only B2D1 (R4, R5) and B2D2 (R13, R14) parameters, but B2D2 (R13, R14) seems other than VW DPF Soot (Measured). I've crosschecked it with VAG DPF and they doesn't match.
In my case after B2D1 the unit&scale code is 0x17 which is Pressure (2 bytes, unsigned, 0...655.36 kPa), after B2D2 the unit&scale code is 0x03 which is Raw (2 bytes, unsigned, 0.01 per bit).

I also get response on
0601: 01C0 2F (0.01% per bit unsigned)
0631: 31C0 B0 (0.003052% per bit signed)
0685: 85C1 FC (0.01 kPa per bit signed), 85C2 FC

I've managed to find the descriptions for the PID's:
0601: Exhaust Gas Sensor Monitor Bank 1 - Sensor 1
0631: EGR Monitor Bank 1
0685: Boost Pressure Control Monitor Bank 1
06B2: PM filter Monitor Bank 1

but unfortunately since the test IDs C0, C1, ..., D1, D2... are manufacturer specific I have no clue what the might be.

Little known fact: the factory does not allow the internal soot calculation model to consider the effects of passive regen on soot loading. That causes the regens to happen much more frequently. This can be seen by comparing the measured soot and calculated soot in vcds. There can be quite a divergence between the soot model and what is actually measured by the sensors!

One of the things we do(pretty sure it's exclusive) with the tune in the 2015 cars is enable the ecu to consider the effects of passive regen in the "calculated" model. This stretches out the interval to 750km or so. And there is less divergence between measured and calculated soot. Also improves fuel economy! the fuel economy benefits are especially with highway driving.
Sorry for being late to the dinner table but I just found this thread.
I Have a mk6 with a recent Kerma tune. My regens are @ or before 200 miles. Is it suposed to enable the ecu to consider the effects of passive regen? Do I need an update on this or anything else?
