This has been asked, I have read about it but would like to make sure.
Will an s4 OMP work fine with an s5 FC?

To build on this; so you might gain a little more knowledge, the S4 is mechanically operated with a shaft from the Throttle Body to the OMP, the S5 is electrically controlled by the ECU.
You are welcome.

And to further complicate things, , , You could, but you would have to use an earlier OMP with the appropriate front cover and a re-chipped S5 ECU (to avoid limp-mode).

Thank you Nismo and I don't think I want to modify this engine just for an OMP, it has 231K miles and is about to die.
