will 5H0907159B module accept earlier version firmwares ?

[elianation]

greetings, haven't found a firmware specific for 5H0907159B and its the only currently available module for sale on AliExpress.
as far as I understood this module was installed on MLB vehicles, im looking to retrofit it on MQB 2019 audi a3.
did anyone try to flash a NO FPA earlier version firmware on it?
does the OP know if its possible?

Thank you for any help in advance.

As far as I know, it’s a gen2.5 module. So you can’t use gen2.0 firmware (check warning section in wiki)
Try find on your local market places gen2.0, usually there are many on sale for cheap

There are unlocked firmwares for gen2.5 tho.

Now that i have it in hand its gen 2.0 part number.

Any of the published here 2.0 firmwares work fine on it
