ABS light stays on. Car was wired up to a diagnostic
machine which gives general readings:ie, sensor problems,
so replaced wheel sensors. No result. Maybe BMW may know what problem is, but I refuse to pay my months salary to find answer. Do you have answers?

Do you
have the same problem?

When a "DSC" or "ASC" issue exists with the E-39 it is almost never the sensors.
First question is what is the production date?
There are several "repair kits" for the anti lock system.
The BMW part # is 34-52-6-752-740 for a DSC unit
and 34-52-6-750-347 for an ASC unit
of course this is dependent on the VIN
the repair module will need to be coded to the car
