Re: DTUA Suport

Yes I've already planned to add DTUA officially, thanks to all the recent positive feedback like yours.

You'll see it in the next app update.

Re: Cffb 2.0 TDI DSG

I agree, this is the common behavior of a DPF switched off during ECU chip tuning.

You can have the confirmation using VCDS or another official diagnostic tester (bosch or similar).

Re: VW Tiguan 2021 Motorcode DTUA APP works perfect!

Thanks for the feedback!

I've received other positive feedback about DTUA in group 18, I think it's time to add it officially in the compatibility list.

Re: hidden value of soot ?

This isn't an issue, it's simply a choice of parameters to show. I decided that NOx sulfur could be more useful that Soot mass measured just because the latter often provides implausible negative values, moreover the DPF regeneration process is based on the calculated soot mass value, so for the app...

Re: Can I initiate regeneration with the app?

You're right, the app is a read only tester. I decided to avoid any kind of active commands because there are many risks in the regeneration process and I prefer to don't implement those kind of commands without having a real full knowledge of the DPF system. The app has been created with reverse en...

Re: 2.0 tdi 2019 dsra engine code

Usually this error means the adapter can't work with full canbus protocol, but works with simplified OBD protocol (2 bytes packets instead of 7 bytes). A good compromise between cost and quality is the Carista adapter, but consider that with it you can solve the connection issue only, after that you...

Re: Engine DTSB

It seems there are part of DTSB working with the app and part not working. Probably the newer ECU software versions have been updated using the new initialization protocol that the app VAG DPF currently doesn't support. Unfortunately there isn't a reliable method to understand what's the protocol in...

Re: Unable to connect

Can you send here more details about the issue? It can be useful to know where exactly the app stops to work and if it raises an error message. Also a screenshot can be useful.
So the app stops working using the same device and the same app release version? Suddenly from a day to another?

Re: Can I use VAG DPF with Engine CRTC 3.0 Tdi ?

Hi, I don't have direct experience with this engine, but I've received one positive feedback in the past. The user sent me a screenshot in which I can see the ECU SW version 4M0907401 0006 and HW version 059907309B. You sw version is probably a newer update. I'm not completely sure about the correct...

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...

Re: Calculated v actual soot mass

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.

Re: 2.0 TDI CFHC wrong filter filling bar percentage

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...

Re: 2.0 TDI CFHC wrong filter filling bar percentage

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...

Re: Seat Leon regen allot

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...

Re: Seat Leon regen allot

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 ...
