VF engineering has a SC working on a 4.2 S4 that is being driven around by AWE. They are installing one on another car in CA for Jeff Moss to work on. He believes they should have units ready to be installed in the S4 within 6 months, and also said it will work in the RS4 with minor modifications. I suspect we will see something for our cars in about a year.
