It seems a complicated issue. What I can tell you is to don't fully trust on what your read from the app because those values can be altered by the ECU, if needed. For example the sudden jump of the soot mass is the common clue of the ECU management: it can force the soot mass filling to 100% to imm...

You're right, it should have been removed in the latest release, but I modified the code incorrectly. Now I'm working on some improvement in the initialization routine to make the engine group selection fully automated also for newer 29-bit init engines like yours. The new release will solve also th...

Ok course, everything can help.

Thanks!

So it's related to the adapter itself.
Unfortunately the APP now doesn't implement the bluetooth pairing function, so that adapter cannot be used.

Interesting, I didn't know some adapters couldn't connect directly to some smartphone.
It's probably something related to the smartphone bluetooth stackup that's usually customized by the smartphone manufacturer.

I know the message is still present in last release, I'm going to fix it.

An important news is that in 2-3 weeks I'm going to analyze a DXPA engine with 29bit init protocol.
A friend finally decided to buy it

With that data I should create an official engine group, removing the BETA statement.

Have you found those parameters in VCDS for your engine?

Huge amount of details! Thanks for sharing. In many cases we (in general) can't be sure if a value is within the specified range and considered ok or not. For example your diff pressure or the injected fuel. Without the design specs we don't have a real reference to evaluate, but sometimes comparing...

Il motore DTRD funziona senza problemi con diverse persone con gruppo motore 18 o 97 a seconda dell'anno di produzione e della versione software. Nel tuo caso, che adattatore OBD hai utilizzato? Non ti posso garantire che funzioni al 100%, ma nel dubbio ti consiglierei di provare con un adattatore d...

Thanks for the hyper detailed post, it isn't common on the web and I'm sure it can help many other users. About your question on the soot charging rate, it's calculated by the app and it isn't coming from the ecu. Its very high number depends on the soot mass calculated value that can jump from a lo...

Good!

I'm working to remove that annoying error that seems to be irrelevant for the app to function, at least with new engines with 29bit init.

Based on your log, it seems you didn't use the group 97 BETA. Can you confirm?

In the app you can select an engine group, no a single engine code. This because many engines share the same diagnostic setup so I've grouped them. If you select a group not suitable for your engine, you simply have "nd" values in the fields, but you risk nothing because for a request of a missing p...

No it doesn't.

OBDeleven adapter works only with OBDeleven app. They've decide to limit its usage to the official app only, so it isn't an ELM327 compatible device and can't be used with any other app.

It means that no answer comes from the ECU, for any request.

If it was working and suddenly stopped to work, I think it's an hardware failure in the OBD adapter. Maybe try it with another app to confirm.

From the screenshot of Milos, the group is 18. You can see it on top right, it's the green number.

Anyway you can try all engine groups and choose the best for you, it's a procedure that takes just some minutes.

Have you been able to read DPF parameters with CarScanner?

It behaves the same way in my Škoda Kodiaq II 2024, there is always error message at the start but then everything works just fine. I think this was introduced with one of the previous versions as in the beginning when the 29-bit protocol was first introduced there was no error message at the start...

On my Ford Tourneo Connect 2025 (which is exactly a rebranded VW Caddy V with MQB-EVO platform and DXR motorcode) the 29bit protocol works, I can see the date even if when I connect I always receive the error message of OBD protocol not established. But then just close message and it works. Log att...

Did you try all available engine groups in the app options? Also the 97 BETA group? Unknown engines can't be assigned to the correct engine group, so the app uses the first group in the list that is the 0. Of course if can be the wrong one for the engine, so you need to change the group and try if u...
