Usually a big jump in the soot mass calculated is related to a differential pressure sensor failure. It's only a statistic. Of course the app can't be used as a diagnostic tested to obtain the exact reason of the failure, but you can start with that sensor, it's the first check that usually is done....

The values are always implausible, but before March they was fine? Correct?

You can try every engine group, if you find correct EGR values in some of them, I can create a new group for your (apparently) different CXHA engine type.

No changes in group 13. I've only introduced the group 15 for some CXHA engines that have a bigger filter with higher limits, but the parameter requests are the same.

Ate the values always implausible or just sometimes?

EGR is working, otherwise you would see a fixed value (usually 100 meaning EGR closed electronically). To check if it's working fine you can fully depress the accelerator pedal and see if the EGR value remains constantly at 100% value. A possibility is that the EGR has been closed mechanically, but ...

What's your engine code?

Also a screenshot could help

good!

how many kms between regenerations?

The app works only with the last diagnostic protocol and your engine uses the old one.
This is the reason why it doesn't work.

The problem is the lack of time, I can't spend so much time for development, test and debug.

Still no plan, sorry.

I don't think it will happen, at least in the near future.

Unfortunately yes, it seems unsupported. I also checked in the mailbox for the similar engines CECB, CEBA and CEBB, but I don't have any feedback. Based on the engine year, it could be correct because the diagnostic protocol was changed near the years 2010-2011 (different depending on brand and engi...

I've just one feedback about it, reporting that it works with engine group 18, despite random connection problems, maybe related to the adapter quality.
I didn't added it because I usually wait at least for 2 / 3 positive feedback.

You can verify by yourself if it works also with your car.

Unfortunately I don't have any feedback about it. The first step, if you have an ELM327 adapter, is to check what parameters can be read changing every engine group in the options. If you're lucky, you could find one or more groups fully compatible with your engine with all parameters readable, othe...

I don't see problem, but with these notes: "distance since last regen." = is the distance correct for you? "time since last regen." = is the time correct for you? "oil ash residue" = seems low, but what's the mileage of your car? "low press. egr closing" = was the engine off when the screenshot was ...

Good, all parameters are read correctly, but now we have to understand if the values are calculated correctly. To do this, the best way is to check a log file containing at least some minutes in normal engine condition and a full regeneration. Alternatively you can take some screenshot at different ...

The engine CAAC isn't officially supported, but almost all parameters can be read setting the engine group 3 in the options. I'm not completely sure about the correctness of the values, maybe if you can post here a screenshot I can give a check. I don't have many information about this engine, I rec...

There is no background service, the app is intended to be used with screen on. A workaround is to use the picture-in-picture (floating window) function keeping a little window on the screen. But if the screen is off, the life of the app depends on the android power save function: the OS can decide t...

It's a known bug, but I didn't understand where is the problem in the code. It seems that the app completely ignore the setting in the options, anyway I'm trying to apply some corrections for next update. You can solve the problem in this way: go into the options menu and disable the option "Automat...

Good advise! I try some color setup and post here the results.

Yes, supported

MY2017 2.0 TDI 140 KW QUATTRO (with torsen, not ultra) S-tronic

Currently it has 76.000 Km and the oil ash is at 25%. With the current rate is should reach the 100% at 300.000 Km more or less.
