Yes it is a low cost, it's a blue elm327 mini

When there isn't communication, it's quite impossibile to understand if the cause is the adapter of the wrong profile in the app, but as said, your engine worked for other users, so I think you could have the same result with a good adapter, replacing your low cost version.

Hello,

I have DSUD 2.0tdi and 3.39.12 app and I am not able to read data as you can see in screen. Any solution?

With my old car 1.6 tdi CAYC it is function.

Can you share the full log copying it in a txt file?
Did you try all engine groups?

Here,group97:
ECU responds to OBD2 requests but not to CAN ISO-15765 requests.

Possible causes:
- engine not supported
- ELM327 faulty or bad quality

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 see a correct answer to a common OBD request, but errors answering to canbus requests. This is the typical behavior of a low quality adapter that works only with OBD2 apps.

OK. But which type of adapter we must use? Better said, what type of protocol is needed? I think, that OBDII is not full compatible and you do not give direct answer what is needed for new types of car. You only say that we have bad quality adapter - what does it mean? Is is not good answer. Thx

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 reduced functionalities versus the full set of functions. This cracked firmware has been made to work with OBD2 apps that send/receive 2 bytes long data packets only. The ISO Canbus protocol supports up to 7 data bytes packet, but those low cost adapters can't manage it.
Then the common question is: how can I identify a cloned fake adapter? It's quite impossible because the companies who sell those adapters declare the full compatibility with all existing protocols in the world, of course. In my experience, the price usually reveals the adapter quality, with some exceptions that depends on how lucky you're in the choice.

To be 100% sure, I usually advise the Carista adapter (both old and new versions are good) because it's produced by a real company with a customer service and a replacement policy in case of fail. It's a little expensive, but it works for sure with all the diagnostic apps.
Further good adapters are the "Konnwei KW902" and the "Vgate iCar 2 Bluetooth" (please note that it requires to press a button to be powered on) that I tested personally.
If you want to spend less, the common strategy is to buy a low cost adapter from Amazon and return it back for free in case it doesn't work. Of course if you can take advantage of the experience of friends, receiving their advice, you can reduce the number of attempts.

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