Who said the dash wouldn't work? It shouldn't be a problem at all.

Are you using a s5 ECU? If you are you need to get the S5 underdash harness, unless you want to rewire your entire car.

And you need the gauge cluster too. You mey want to think about going EMS.

I did the swap, the entire swap...S4 car w/ S5 everything else. You will need to rewire your dash and you do need the newer cluster. Just the way it is...it's a big PIA and I highly recommend to go EMS first off... put aside a grand or so for one....
