ApplagApp Forum

Thanks for the feedback. I check again in my database is this is a mistake or not. Very often the parameters setup depends on the engine code but also on the sw version. It's possibile that I have a log of another CAAC engine with parameters different from yours, in this case I can split the CAAC en...

I have been stuck for many days due to flu, I should give a deep check to your message in next weekend.

No I'm sorry, I checked but I don't have that document.

My first suggestion is for groups 14 and 12, but you can try every group and choose the best one.

Good explanation thanks.

I always thought it was a calculation error, but it's very strange that in more than 10 years of car end ecu development, this error hasn't been corrected by vag engineers. It seems that it has some useful meaning, also with those negative values.

Let me check the code, maybe there is a bug.

Are you using the last version 2.24.4?

Yes that option is to set the limit in case the app doesn't recognize it correctly. You can change it if you see that your engine starts the regeneration always far from the 100% value. It depends mainly on the filter dimensions, some engines have it bigger then the standard one. The number of engin...

You can find similar experiences in this forum. In many cases, the defect has been found in the differential pressure sensor. Of course it's impossible to make a reliable diagnosis remotely, but your DPF system doesn't work well so I suggest to ask help to an expert who can use specific diagnostic i...

Clear. In my experience, a similar behavior is due to a defective differential sensor. But this is just my opinion, you should ask to an expert that can verify with diagnostic instruments. Anyway the calculated soot mass is the value that the ECU uses to start and stop the field regeneration process...

Question 1: to me, your values seem ok, I don't see big difference versus my 2.0 TDI DETA. Question 2: I don't understand your question ... you don't want to see the NOx charge? What happens when the regen occurs every 50 miles? Do the measured soot mass raise pretty regular or it suddenly jumps to ...

No news

Unfortunately it isn't supported yet because recent TDIs use a new 29-bit initialization protocol that I can't analyze because I don't have the opportunity to take a car for some weeks for test. I keep searching asking to friends and rental companies, but at the moment I didn't find anything.

Try all other groups, maybe some of them gives you more data.

Very good news!

Thanks for sharing with us, it will be useful for sure for other users with similar problem.

There's something wrong in the data reading.
Try to set another engine group in the options menu, the CAYC 1.6 TDI has more than one group depending on the software version, but I didn't tested all of them so the automatic group seleciton could be not 100% reliable.

A custom notification can be implemented quite easily.
I add it to the TODO list

I've understood that new engines use a new initialization protocol with 29bit instead of 11bit, this should be the change that makes the app not working with new engines. This new protocol should be relatively easy to implement, but unfortunately I can't find any car for my test. I asked to friends ...

Sorry I realized now that you asked for an estimation for the next regeneration while I've explained a feature to predict the regeneration duration. The feature you ask would require a constant connection between the app and the engine to read and collect all the information. If you connect the app ...

It would be a good feature! I already tried to implement it, but after many tests I decided to discard it due to poor reliability in the predictions. Unfortunately the regeneration process doesn't follow a linear soot reduction, moreover there are many external factors that can change the regenerati...
