    Sounds like either clutch is contaminated with oil from a leaking crank seal (unlikely given the car's age) or a faulty dual-mass flywheel.

    The clutch judder could just be down to driving style. Mastering the clutch on S4's takes some time. Also a remap alone will get you no where near 400bhp from the V8 lump. A complete system including sports cats plus the removal of the down pipe cats and a map will probably get aorund 380bhp on a good day.
