Your Mondeo MK5 isn't covered by FDRS? When you buy things you have to check first if this is good for you.
For Mondeo Mk5 you need IDS and Fords VCM2 or Ford VCM3 or FJDS with a passthru
Maybe you did confusion between FDRS and FJDS.
In conclusion uninstall IDS and install FJDS. Do not uninstall FDRS.
Good luck
