Hi thank you so much for describing the flash procedure. Probably its my bad that I missed giving context of what I am doing. I had a 3AA902273B which I was able to flash to 3AA902273D. Now since I wanted the sensors to be detected automatically, I wanted to flash it to F version. But it keeps failing while trying to get a seed to flash the TPMS ECU. From that I understand the Security Access code thats being used by VCP to flash the file is incorrect.

There is a possibility that the flash file I am using to update the TPMS Module is modified. As the EXPECTED-IDENT specifies 5Q0 modules

EXPECTED-IDENT is not really important for programming session: this list is used only by flashing software (f.e. ODIS E or VCP). To unlock access to flash firmware only SA is important and session type. Software can validate selected ECU by partnumber, but there is no problem to skip this validation if you know you are doing.
So try first play with session type first and project type
