Your engine should work. I have some reports that confirm it can be connected to the app using engine group 10. Unfortunately, I don't have confirmation for all 12 fields because I received only static screenshots in which I can't understand if visible values change correctly while driving. If you w...

Connecting with Bluetooth ELM327 adapter Before connecting the app, you have to pair the device to the adapter using the standard bluetooth connection menu of the Android device. To be paired, the adapter must be powered on (connected to the car or to a 12V supplier) When your adapter is paired, yo...

From top to bottom, there are 4 sections: status bar, commands and icons, data fields, static data. Status bar section Section_1.jpg In this section you can see from left to right: app icon, app name, setting menu icon, data log recording icon, sounds icon, help icon, FAQ icon and exit commands. Ico...

It would be great also for me, but in my current condition, as single non-professional developer, it's impossible to plan a new development language learning. I'm sorry.

Here the answers based on what I've learned in last years (I'm not an engine technician): Post injections are used by engine ECU to reduce nocive emissions and engine noise, the difference between 1 2 and 3 is just the timing, number 2 is after number 1 and number 3 is after number 2, in normal use ...

Yes I agree, I've tried to use it during my tests, but the refresh rate make it unusable because what you see on the screen (or in the log file) is not synchronized well to other fields due to bluetooth communication delay.
Moreover I don't have space to add further fields on screen, actually.

My actual plan is to separate data that need to be refreshed quickly and data that are almost always static. For example, I don't need to check in every data update the value of the oil ash deposit because it changes very rarely. Probably the best solution is to keep static data in a separate page t...

Yes I confirm it would be possibile to add the oil level. Not all engines have it available, but most recent have it. The problem now it that I don't have space enough to add new fields. I have a list of useful fields to be added, but I can't proceed without a graphical redesign that actually isn't ...

I've found some email of 2016-2017 and it seems this engine isn't supported. It should use the old VW diagnostic protocol, in fact using VCDS you'll see the old measuring block form with the group fields instead of the new measuring block method with advanced measuring and UDS requests.

Bye

Unfortunately old engines, like yours, using the old VW diagnostic protocol ISO-TP 2.0 don't work with my app.
I developed the app on the last protocol that is completely different from the previous.

I'm sorry

This is a world I need to explore. Probably I did never start because I don't have Android Auto in my car, so it would be difficult to test a beta version.

The ECU parameter list is enormous. I know every user would like to have many parameters available, but with this app I'm focusing only on DPF so I prefer to avoid parameters not directly related to DPF and its functionality. The problem is that more parameters means low reading frequency and I don'...

Interesting! I'll give a check.

I'm studying the relationship between differential pressure and air mass just to understand if the ratio is constant. Looking the average values it seems yes, but I think the big problem is the reading speed of the app. Unfortunately I can't have realtime values so for these kind of parameters that ...

There are two options that can help you:
Auto connect on start
Enable auto-update function on start

With these two options enabled, when you launch the app it connects and starts to read data automatically. Isn't it enough for you? Just a single tap in the icon is requested.

Hi Radek,
interesting post.

But I don't understand what's the problem using excel to generate a graph. I use it daily without problems, I simply put all (or needed) data in a line graph and the time in X axis.
If I understand the problem, maybe I can correct the format.

For the regeneration process, I think the post injection 3 value is most important than coolant temperature. Don't you agree? Maybe you're asking for that value generally speaking. In this case I agree with you, but this app was created focusing on DPF filter and its regeneration, so I need to show ...

The following chapter, taken from an official VAG technical document of a CRBC engine, explains the phases of the regeneration process in an EA288 TDI engine. The same principles can be used for all recent VAG TDI engines. The regeneration of the particulate filter takes place in the following stage...

Today I logged some values from my TDI and placed in a graph ;) I included also the DPF gas volume that isn't present in released app, just to understand the relationship between the ratio [differential pressure/air volume] and the [soot mass calculate]. As reported in technical documents, in fact, ...

Very good! Your report will be useful for other people for sure.

Sometimes they ask me to check if the differential pressure values are correct, but I can't say that because I don't have experience about sensor failures.
Your report give us an evidence of a possible failure.

Thanks
