hmm....i just looked on the driver's side door and the build date (11/99) was stamped there. I cannot see the ECU giving any more or different info, but who knows.......
Quite frankly, I am surprised that my EARLY S4 has not given me the problems of some other owners. I guess I have a (built on) "Tuesday car."

just my .$02

00 S4 (11/99 build date)
