Re: New engine type?

It's a problem related to the new TDI engines, their protocol has something different that makes the app not working.
I'm working on this issue and I'm waiting to find a car for test near to me.

Re: Bluetooth vs USB adapter

I never experimented an USB cable in my test because for automotive/obd software, the USB version is very rare.
What I know is that the bluetooth version has a physiological delay due to the bluetooth communication, but for OBD non-professional data reading can be accepted.

Re: What does this all mean?

Just another question: have been your ECU chip tuned? I ask this because an engine working in recovery state without any warning light on (and no errors in the log) is a common case that happens when the tuner removes all the diagnostic functions in the ECU to prevent any problems, for himself of co...

Re: Passat B6 CBDC

You can see the answer in the FAQ:

Your engine uses the old diagnostic protocol that isn't supported by the app.

Re: More exhaust temperatures available?

The double value is a different way to request data to the ECU available in the ISO specs. This single request contains the 2 parameters and the single answer contains the 2 values. It would be a faster way to duplicate the fields available on the screen, losing only some milliseconds due to the sli...

Re: More exhaust temperatures available?

Very new car 8-) I confirm, this engine heavily uses the 2 EGR valves, in fact in my experience the regenerations occur every about 250-300 km. Customizable fields is a possibility to add new values as well as a new page, but the big problem for me is to collect similar information from different en...

Re: More exhaust temperatures available?

I have DETA engine too ;) Yes it would be possibile to read canbus and obd protocol at the same time, but this solve only one of my limits .. the screen size is limited, I'd like to add more useful data, but I had to make a choice to select only the 12 most important values and to keep the app more ...

Re: More exhaust temperatures available?

Interesting topic! What's your engine type? I know the regeneration process and I agree that there are many other parameters useful to understand what the engine is doing, but my main problems are the limited screen size and the differences between every VAG engine. Unfortunately, VAG doesn't have a...

Re: What does this all mean?

There something strange in this picture, the soot mass calculated value clearly is impossible and also time/distance since las regen value are very high. Moreover if you report strange engine behaviors, I think there is something faulty in the system, but it's pretty impossibile to understand where ...

Re: CAYC 1.6 TDI

In all the technical documentation I've found, I never read anything about the soot mass measured value. All diagnostic procedures refer to the soot mass calculated. Moreover the measured value gives weird data, sometimes negative and sometimes decreasing while the calculated value increases. The on...

Re: CAYC 1.6 TDI

It's difficult to know that. The soot mass calculated can be wrong if some sensor provides wrong data that make the entire calculation wrong. The ECU has internal diagnostic routines that give it information to understand if some sensor is faulty and consequently anticipates the regeneration. The su...

Re: CAYC 1.6 TDI

This is usually a symptom of a failure in some sensor, but it's impossible to know which one using my app. You should ask for a full diagnostic check to an official service or to a good mechanic. Your log is another confirmation that the soot mass measured value becomes a real usable value when ther...

Re: CAYC 1.6 TDI

Considering only March and April 2021, I see: a regeneration started with soot mass 21,36 grams and finished at 4,6 grams in the log "Save date(yyyy-MM-dd HH:mm:ss): 2021-03-20 15:21:03" a regeneration started with soot mass 21,66 grams and finished at 6,38 grams in the log "Save date(yyyy-MM-dd HH:...

Re: CAYC 1.6 TDI

Yes it is.

But I don't find any issue in it, every regeneration started with correct soot mass values.
This is the list of the soot mass values just before the regeneration starting:

Maybe the regeneration you mention weren't logged?
Do you remember the days when they happened?

Re: Sporadic connection errors

What kind of adapter are you using?

First suggestion is to set the update delay to 0, many cheap adapters don't like delays in the communication flow.
IF the problem persists, you can check if also with other applications you have the same disconnections.

Re: CAYC 1.6 TDI

These pictures are not useful because you can see the fields "distance since last regen" and "time since last regen" have already been reset after the regeneration completion.

The log file is usually saved in the "VAG_DPF" folder in the internal SD, if you didn't change it.

Re: CAYC 1.6 TDI

I see you've enabled the logging, you can easily verify what was the time and distance since last regeneration before the process started.
Or you can share the log here if you want.

Can you confirm your engine didn't receive a software update?

Re: CAYC 1.6 TDI

Have you checked what are the time and distance since last regen when the regeneration starts?

Today your engine starts to regenerate every time near 13 grams or it happens sometimes?

Re: 2012 Touareg CRCA , exhaust gas temperature

In last release I created a new group for CRCA engine with all working parameters. I decided to add input gas temperature and simulated DPF surface temperature.
Let me know if it works well
