ApplagApp Forum

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...

It probably uses the old diagnostic protocol that isn't supported by the app. Based on what I've seen to date, the current protocol has been intruduced nead 2010-2011 depending on brand and model, moreover all the engines with new protocol have the 4 digit engine code. There aren't engines with 3 di...

I confirm those sounds are present, but only in the full pay app.

• field regeneration started

• field regeneration ended/paused

• passive regeneration started

The lite app doesn't have sounds.

Yes I meant the official VW service guys, just to understand if they already know this kind of issue. Usually they can also contact the main service office in Germany if there isn't valid solutions to implement. Of course, if you are outside the legal warranty period, you could pay for the service a...

Your previous message was probably accidentally discarded inside the tons of spam I receive today. My apologize. This seems a crazy issue. I've analyzed the logs and everything seems ok but the regeneration speed is extremely slow. I agree with you that the output gas temperature is lower that what ...

I don't have plan to introduce compatibility with the old protocol.
I started an analysis some year ago, but founding many blocking problems, I decided to abort the activity.

Thanks, I appreciate

What do you need to know exactly?

Some events launch a notification sound, do you need to know which ones?
