Not all DTTC engines work, some of them have the new protocol and some not. Probably the MY22 has the new 29 bit init protocol

What exactly happens? It randomly works or never works?

Did you already tried different engine groups? You can manually select it in the options menu.

Is this a fresh install or the issue depends on the last release update?

Yes I used official ODIS that confirmed negative soot mass measured values. My advice is to ignore the measured value and check only the calculated one. You could need to check also the measured value only in case of failure, for exmaple if you see a sudden jump of the calculated value, synthom of s...

I don't have evidence of this behavior, but I know that it was a common practice.
It probably depends also on the engine type, for example a big 2.0 TDI should need less aids than a 1.6 or 1.2 TDI.

It's an impossible value, but it's what the ECU shows us. I checked with the official diagnostic software, it's the same value. We don't know what the VAG engineers want to provide with that value, but it seems that when there is a failure in the DPF system, the soot measured value becomes correct w...

I don't know if it's my problem, but I see a black image.

Anyway, try so set the engine group 2.
As you said, the engine CFFD is similar to the CFFB, probably only a different power version with the same electronic.

Your engine probably uses the last modified diagnostic protocol with 29bit initialization instead of the previous 11bit. It ins't a big change, but it requires many days of test and debug in which I need to have a car available full time that I don't have. But I keep serching for it, I also asked to...

Probably a new engine with 29bit initialization diagnostic protocol.
At the moment it isn't supported by the app, I'm sorry.

CFFB is supported > 2.0 TDI 140HP.

You can check with the free app first, you only need a good ELM327 adapter.

Yes thanks, the selection is made checking the ECU SW number. With the information provided I can include your version in the correct engine group.

You can wait for other answers, but usually this kind of behavior is related to the differential pressure sensor. Anyway the best would be to check the entire system with a diagnostic software to find the real problem. When the system detectns a failure, the regenerations are closer because the ECU ...

You need to find your engine code and then check if it's supported in the engine list in the play store page.
The engine code can be found in the service booklet or in the vehicle registration document.

If you can't find it, post your engine and car details.

I started months ago to analyze this kind of adapters, but due to the limited free time, I didn't go deep in the analysis. At the moment I'm not working on it, I'm sorry.

I don't have experience with that engine, neither feedback from users.
Very recent engine introduced a new canbus initializazion method that the app currently doesn't support, but there isn't an easy way to understand if an engine uses this new method or not.
The only way is to try using the free app.

I know that illegal seller, I noticed the presence of the app in the Huawei store and I immediately contacted the Huawei support to remove it.
It was a cloned app, I neve added my app to that store.

Thanks for the feedback, this means that some error can reside within the code. Useful information

In my experience, this issue happens very few times, more or less every 2-3 months.
If you experience it many times per day, I can only suggest to try with another good adapter.
Probably the adapter quality has an impact on the issue.

The free and the full app share the same connection protocol. I've experienced this kind of issue too using a good adapter: it seems random so I can't understand if is the ECU that refuses the connection or the app that asks something wrong to the ECU. Maybe it's just a matter of bad timings, but I ...

Usually you can see the filter performance drop year by year and the first consequence is a reduced mileage between the regenerations. There isn't a fixed value ok Km to be used as reference because each engine and each driving style can heavily increase or decrease it. The best way would be to comp...
