RS4 V's S4 ECU

Post by tartan_rob » Mon Mar 01, 2004 7:15 pm

Are these ECU's directly interchangeable..? The engine (I believe) are the same with different turbo's and cams on the RS4. But other than that I think they are the same. Anyone know?

My understanding is that a late S4 has the same wiring loom and ECU as the RS4 (obviously with different software). I know for a fact that the early S4's are very different in the wiring and ECU type. Hope that helps.
