the harnesses and sensors are different. provide more detail, but just from what you posted it will not work.

You do realize that it's an EXTREME pain in the *** to just swap ECU's between series right? To begin, the s5 ECU expects an electric oil pump, dual tps, and various other things. Not to mention they don't mismatch with the harnesses.
