Only AOS ISTA. Some chinese guy offer secure coding service on Facebook with an Esys screen about coding success, but I think that scam.

- Source coding (NCD 2.0) with e-sys offline is completely fine, as long as you have the NCD 2.0 files signed online by BMW.
- Below is my understanding of NCD 2.0.
   - Concepts:
    * CAF (Coding Application File): Contains the coding data of a ECU. Roughly understood as raw data.
    * NCD (Netto Coding Data): Is CAF with specific coding data (fit with FA, ECU) and Signature.
   - Basic differences between coding 1.0 and 2.0:
    * Coding 1.0: CAF and key to sign cafd are available in psdzdata.  -> NCD is created by E-SYS
    * Coding 2.0: CAF and key to sign on the cloud (BMW backend).  -> NCD is cannot created from E-SYS BUT coding is normal if have NCD file.
- To get the NCD 2.0 file you need to have access to the BMW backend (ISTA online, API and also with E-SYS if you have an account/certificate)

There must be another way to geht the ncd files, with AOS you can not download the ncd files without connected car.You get them on the fly while coding via online Ista.
But how to get the ncd without car, only with FA and SVT?

Yes right, only with FA and SVT need. But not from AOS(maybe also possible, i don't know).

Of course this is possible. You can buy NCD 2.0 easily, just send FA and SVT to the seller. As for how/what they did to get NCD, of course it will not be made public.

I know how to get this from other sellers, this sellers are a lot, so i think i t could not be that complicated to get this files.
Maybe someone know and will share his know how.

No one of the sellers will be able to sign the CAF s by them self . Because nobody is able to give you fdl changed files, only VO.
So they buy complete ncd/CAF packages that are already signed from some russians i think

hello,

The signing is also done with the chassis number, which is why the NCD cannot be exchanged.

My guess is that they reverse engineered the ISTA protocol, either with sgate or aos login.

To clarify, at the moment there is no solution to encode a modified CAFD file?

No

Has anyone tried to change the FA, upload it to VCM and use ISTA Online to encode ecu with the changed FA? I wonder if ISTA downloads the vehicle order from the server or from the car
