Hi guys,


I have quesstion for you if somebody can help with changing software version for AUDI R8 4.2FSI V8 2014 Stronic, CNDA engine code. Now I have 420910560S_0020 in 420910560C MED9.1.2 ECU. Can you tell me which version is changeable for this 420910560S? Need to change due to TUV control. With actual SW version cannot pass control, due to missing readiness data in OBD.

Thank you in advance for any help.

Are you from Germany because of the "TÜV"? If so there is no need for the readiness Codes anymore, since the "VAG-Abgasskandal" in Germany all Vehicles need to be checked with a real Emissions-Test, the Check where only the OBD Data is controlled is canceled some years ago. So you good to go, if there are no fault codes in the Engine Control Unit and the Emissions is OK, you pass the so called "AU Abgas Untersuchung".

Thank you for reply.

Yes, I know but check engine light must blink on before start and on this actual software won´t. I know it can be done this way, but I need to help which version is changeable to this ECU. Also helps me, if somebody can provide original FRF 420910560S_0020 file.

Thanks in advance.

Yes the "MIL" needs to work correct.
It looks like there is no original Firmware in the Flashdisks from Audi. This happens when there is no update for the factory firmware. I guess only updates are on the flashdisk but no factory ones.

I know it :/ Thats why I am asking for help. I am sure, this frf/odx file exists, but it is not in common databanks here on the Internet :/ Maybe someone can tell which version is compatible to flash on this ECU.

[karlfrosch]

I think ther won´t be a compatible file from an diffrent unit. U need someone who got a copy of the original ECU or can do a copy.

You can try to use 420910560M_0030.sgo from the database.
