Thanks for the feedback. I'll add it in the next release.

Interesting that a model year 2025 still uses the previous 11bit protocol.
Maybe VAG changes protocol only when there is an important update in hardware or software.

DSRB isn't officially present, but I've received positive feedback using engine group 18. You can try if it works also for you.

In my experience, it's normal. The regeneration process stops near that value to dont increase the overall time of many minutes with low soot reduction. The reduction rate is higher when the filter is full and decreases when it's almost empty, this means that to remove the same quantity of soot, mor...

The app doesn't work with BLS and all other engines that have the old VW ISOP-TP 2.0 diagnostic protocol. VAG changed the protocol in years 2010-2011 depending on brand and model. I developed the app on the new protocol and I never added the compatibility with the old one because I never had the opp...

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 y...

Ok ELM327, but what brand/model? Is it a low cost version?

Mmm interesting, can you post a screenshot? So I can read the ECU sw/hw versions. Thanks

Cupra formentor dttc engine.

It seems the same engine of eulogitos in this thread, and the beta profile worked for him.
What's your elm adapter? It seems it doesn't agree the first canbus commands that require the ECU parameters.

Published release 3.40.12 right now

After the initialization connection, the app can start reading the parameters if you selected the related option, or enable the REFRESH button to let you update manually. I see in your picture the REFRESH button disabled, this means that the app is stuck waiting for some confirmation from the ELM ad...

What engine group you selected?

One user confirmed me by email that the engine works, but without telling me the used gruop.
Anyway, you can try all engine groups, probably one of them is good for your engine.
Let me know what you find.

I confirm, engines with NOx filter have little short regenerations to reduce that value. They are very short and normally you don't notice them. With the app you can suddenly see a temporary temperatures increasing with some post injections and, with the NOx value visible, you will see the NOx decre...

Unfortunately the differential pressure value wasn't available when I tested the CXXB engine in 2017, this is the reason why it isn't present, as already explained by email. Anyway I'm trying to find new information about it. The post injections must be present for sure during the regeneration becau...

You can make some test by playing with the "field regeneration limit" parameter that lets you change the value corresponding to the 100% filling. It's happened many times that a 30 grams value is the correct one, in fact I added that option just for those cases. Anyway try and let me know what's the...

My apologize, I've been very busy for other problems in last 2 weeks. I'm going to work on the app in next days, the changes have been already implemented, I need just some test before to publish. I wanted to add an auto-select function reading from the ecu, but it requires more days so I decided to...

I don't have any comment or request about it, you're the first. It isn't supported, but you can try the existing engine groups, probably with one of them you can read the parameters. Pay attention to the adapter, the low cost dongles don't work with the app because they don't fully support the ELM32...

Hello, in my database the "nox sulfur charge" value seems to remain always zero with some ECU software version. At the moment I don't have positive feedback for all sw versions, so it remains partially supported.

I confirm it's a bug and it's going to be corrected in the next release.
It's related to the car mileage reading that raises an error instead of skipping it when the parameter isn't available in the engine ECU.

I mean risk of fire. The standard ECU management is full of safety routines to avoid fire, also in case of sensor or system failures. An example is the forced regeneration after a fixed amount of minutes or km, regardless of all the sensor values. This prevents the clogging of the filter that can pr...
