CEBA is a 2.5 TDI 5-cyl engine designed before 2010. It's very likely it uses the old diagnostic protocol that VAG DPF app doesn't support.
I'm not 100% sure because I never had the chance to test it directly, but I'm quite sure.

No plan for CBAB, it uses the old diagnostic protocol and I don't have any chance to have a car available for months for test & debug.

Aboud CDCA, I have no feedback from users neither direct experience. You could try using every engine group available in the options, maybe some of them is working.

Thanks for the update, I can definitely add CJCC to group 2 in next release.

I confirm it can work with group 10, but you can also try 2 and 16 too. Communication errors occur when one or more fields can't be read due to partial compatibility, in this case you can skip those fields simply tapping on them and the app won't read them again, saving time. Try that 3 groups (and ...

The app already has a keep-alive function that keeps the screen on while there is data communication so when the automatic data update is active (green arrows on the filter image). I owned a S24 ultra and that function worked fine. Maybe you move the app in background? It must be in foreground in fu...

For engines without the soot mass calculated value, I use the nox sulfur charge as second option. For CUNA engine I probably missed the soot calculated in my first scan, but recently many users asked me to add it because it's actually available. In the layout I decided to keep only few parameters fo...

Unfortunately I don't have any feedback about that engine. It should belong to the same 2.0 TDI family used by many vag cars that the app support, so there's a good chance it will work with the app. You could try using the free app and a good ELM327 adapter. Try switching every engine group in the o...

DTTA should work using the group 97 that is a special group created to test the new protocol with 29 bit initialization. I've received some positive feedbacks so I'm pretty confident it works.

You can try groups 18 and 97 for DTTA.

You can find the best engine group using the free app and then buy the full app if you're satisfied of the results. If you find a group that reads all the parameters correctly, you can keep it selected as a custom group. There is no difference between the automatic selection and a custom selection i...

Non l'ho mai testato direttamente ed ho un solo riscontro positivo di un commento su youtube.
Vista l'età dell'auto ci sono buone probabilità che funzioni, se vuoi provare.

Just a quick update: the car interface layout is almost ready, it's been quite easy because it's forbidden to create complicated layouts, the only real issue is that I can't try the app while driving, only the PC emulator is allowed. Now I'm working on the app structure because I must build a strong...

The application does not connect to this engine, can you help?

What engine code?

Basically, every "real" ELM327 adapter works. The app requires an adapter that can manage all the commands specified by ELM electronics for its chip. So where is the issue? The issue is in the "real" word written above: the most of the low cost adapters are fake, they use a cracked old firmware with...

Here,group97: ECU responds to OBD2 requests but not to CAN ISO-15765 requests. DSUD has been confirmed as working with group 97 by misiakpb, you can find details in this topic: Everything's fine, your engine DSUD is definitely supported. Maybe you're using a low quality ELM adapter? In the log I se...

Car scanner should write a connection log, can you send me that? Also by email applagapp@gmail.com if you don't want to share with all here.

The reason why you can't find any information is because your engine uses the old diagnostic VW-TP-2.0 protocol that the app doesn't support. I don't have a plan to expand the compatibility also to that one. I tried years ago but with poor results and many limitations, so I aborted that try, I'm sor...

Currently no because there isn't a background service for the connection management. The app has been created to be used in foreground on the screen, also because in that time I wasn't so expert in java language. To implement what you ask, I should redesign many of the core structure with many test ...

It seems a professional analysis.
Good luck and thanks for sharing the results!

Unfortunately, it's a common practice to follow the on board diagnostic only. If there aren't errors, the system works fine for them. The expensive solution is to replace everything (but we know that sometimes also this strategy doesn't solve with these so complicated cars), the cheapest one would b...
