Hi i have new EVO engine code: DSUD.
I Will try app in few days (waiting to receive OBD adapter).
If there wil not be support for this engine, than can i help you with read data and enable support for it ?
Thank you.

Unfortunately, remotely you can't help me.
I'd need to connect my instruments to the car.

Anyway, last engines usually work with my app, but after connecting it, you should manually try every engine group to find the best one for your engine.

Let me know

Hi

I tried manually switch all groups. But nothing works
Tried other car (old VW Passat B7) all work OK.

Also i have VCDS (legal) and i read this data - see attached file. Maybe can help you.

During the test, have you noted if at the bottom of the screen are present ECU data? There are 4 pink texts.
Maybe if you've taken a screenshot, you could share it.

No - nothnig there

And are you using an adapter already tested successfully with another car, right?

It's really strange that VAG has changed again the diagnostic requests setup

Yes, adapter is good,tested on 2 older engines .. and working OK.
Did you download file with prinst screens ? In my post shared via dropbox ?

Yes, I did, but it can't help me because I need to know the CANBUS raw data.

I try to find more information about your engine.

Hi, did you find somethink ?

Nothing useful for my app ... I keep searching.

Hi .. no new info ? Thank You

Still nothing, the engine is too recent and I didn't have any opportunity to test it yet.

Hi, somethink new ? about new engines ?

The last full version contains the new group 18 for DTTC 2021 engine that I tested physically.
If you're using the free version, the engine group 5 should give you readable data, but your problem is that the initialization doesn't finish correctly.

With DTTC engine I've verified that the protocol is the same, only some parameter requires a new request string.
I think that new 2021 TDI engines don't require a new protocol format, simply they need new request strings or formulas.


I think that also your DSUD engine should follow the same rule and I would suggest you to try with a better ELM adapter, but it's strange that you've tested successfully it with another car. In your case I don't know where is the problem, if in the adapter or in the app.
A possibile reason can be that new TDIs require an adapter with better quality than older TDI, but this is just a personal hypothesis.

If you don't have the possibility to use another adapter, the only thing we can do is to wait for some other feedback about DSUD engine.

i have full, and it doesnt work with group 18 at all no data

Hello, I tried to connect vagdpf on Leon KL1 (2.0 TDI from 2023) with engine code DTTC and it didn't connect. Also I have the release 3.29.12

Your ECU probably has the new 29bit initialization protocol that the app doesn't support.

29bit initialization protocol - can be implemented ?

Hello, have you any new information about new TDi engines (from 2020)? I have DSU 2.0TDi from 2020, and app version 3.37.12 and it doesnt works with myl ELM adapter (with older it works).

I'm working on the 29bit init protocol with the help of the users, you can give a check here:
