DTUA Suport

[Fabijanovicic]

Hey,i am wondering is new 2.0TDI DTUA engine supported.Thank you

[admin]

I've just one feedback about it, reporting that it works with engine group 18, despite random connection problems, maybe related to the adapter quality.
I didn't added it because I usually wait at least for 2 / 3 positive feedback.

You can verify by yourself if it works also with your car.

Unfortunately it doesn't work with my Octavia IV DTUA.
I've tried various options starting from group 18 but with no luck.
I have used this perfectly with my Superb III but can't connect with my new Octavia.
I have attached the screenshot when connecting to the interface.

Interface used is VGATE.

Can you advise when you will be able to add the support for this engine?

[admin]

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 and also to rental companies, but with no luck.

I should have the availability of the car for at least some weeks to make test and debug, it isn't matter of some minutes so I can't quickly connect my pc to a friend's car and have the result.

I keep searching.

Dear admin,
I think all new 2.0 TDI from MY2023 will have 29bit initialization protocol, so it is essential to implement it.
Is there any way to suport you in this transition?
The protocol itself is already been broken long ago.
DPF Control uses this protocol with success. https://ms-group.pl/en/product/dpf-cont ... -cr-group/
Maybe some extra contribution would help?

Since I can't yet write a private massage I post here.
Dear admin. Do you have an access to EN/DE versions of SSP 595 - The 2.0l TDI engines of the EA288 EVO diesel engine series
I have only SSP671 with DFBA but this engine is for Audi only and it is M-HEV. Basically the same but there are some differences.

[admin]

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

Good news. My new Superb MY2024 has an old 11-bit protocol.
I selected group 18 (DTTC) and have all parameters displayed. Would you consider to add DTUA to group 18?
All other groups did not do the trick. Will not do it for Octavia IV. Tested with other engines. New platform, new protocol.

[admin]

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.

nUn saludo

Hello, I am a user of a Cupra Formentor 2.0 Tdi from the year 2021 with engine code DTTA and it does not connect either by entering vagdpf in code dttc group 18.

Do you know anything about it?
I had a 2015 Sean Leon TDI 1.6 and it connected without problems.

Hi, I added the english translation to your message.

If you used the same obd adapter for both engines, this means that the adapter can work with canbus diagnostic, so the problem is the unsupported initialization protocol that last TDI engines have.
Unfortunately I didn't have the opportunity to analyze those new TDIs yet. The app currently doens't support the last initialization protocol, introduced around 2022 depending on the model.

Which interface are you using with your Superb? Model / make?

Admin - is there any chance for support of DTUA?

[admin]

I'm working on it, you can give a check here:
