MarkD has software that works great in the all the 540's, right from 1997 to 2003 . If any of you have a later 540 and were not happy, just contact him for a fix. What probably happened is that your car was flashed via the OBD-2 port instead of the round ADS connector. This connector is even in some 2000 540's.
