Hi,

is it possible to make a downgrade for this Ecu for a Softwareversion before Diesel gate which looks like a newer Software Version?
I mean can i fix Version 7450 that it looks for Diganosis like 9977?

Ok, what is the best way....
Downgrade to 7450 and then send you the flash of 7450 or what?

Thanks, AudiRS

you must flash ecu with .frf or .sgo file with ODIS,Autotuner .... etc... but i know on germany TUV control they checking cvn ....

Thats the reason why i`m asking for a solution where i can have the right file (pre-dieselgate) on car which looks like a Dieselgate 9977 file.
To flash to a older version is not the problem, but need a solution that car pass the TÜV control.
