IPC Firmware files

Hi all, can anyone kindly point me in the right direction to find the appropriate older IPC firmware files for my Mondeo please?

I’ve updated the firmware recently and although it all appeared to be fine,soon realised certain functionality has since been broken and I think the only way to remedy it is to revert the IPC back to its older software version but can’t seem to find what I need.

It’s a late 2015 Mondeo mk5 so I’m guessing it’s either the very first or at least one of the earliest firmwares.

Thank you in advance if anyone can help, it’s annoying not being able to change climate options properly :sob:
