Стандартным методом ODIS скорее всего не даст шить старые версии (...589A/C/E) поверх прошивки ...589G.
В файле frf содержится информация о идентах блоков допустимых для данного апдейта.
На рисунке видно, что залить прошивку G в блоки A,C и E можно, а наоборот E или A,C в блок с прошивкой G нельзя.

The standard ODIS method most likely will not let you flash old versions (...589A/C/E) over the firmware ...589G.
The frf file contains information about block identifiers valid for this update.
The figure shows that it is possible to fill firmware G into blocks A, C and E,
but vice versa E or A, C into a block with firmware G is impossible.

In my another car 2012 Q7 I can with same Odis-e upgrade or downgrade transmission soft.
Why I cant now in A6 make this?

Ask the answer to this question to the manufacturer why they did it.
They already got hit on the head once for environmental tricks.
Apparently they don't want to get it again. :shock:
These firmware problems can be bypassed, but standard equipment such as ODIS will not allow this.
The solution lies closer to the topic of chiptuning and specialists in this matter.

Maybe this “E” file can somehow mod for eating with Odis?

Do you hear something about cryptography?
You can't make modified ODX/FRF unless you have private RSA key known to manufacturer only or unless you have access to OEM smartcards/keychain.

Also :smile: it is possible if you have a quantum computer with a few thousand qubits to find the private key that matches the public key. :biggrin1:

Thanks for information! Will search some tuner with right hardware.
