Unfortunately there are several possibilities that are common to causing the light to come on. I would suggest taking the car in to a dealer and having them read out the fault memory. Such possibilities are a failed speed sensor, a binding DSC/ACS actuator cable, or faulty DCS/ASC control unit. If you know how, you can disconnect the speed sensors, and check for voltage output across the the terminals inside the connector going to the speed sensor while rotating the wheel. A dealer should charge you about an 1hour fee to check out your system. Due to the cost of parts involved, I would recommend having it checked before just guessing.

the fuses u are looking for are as follows:
From the top left first row its# 4
then the bottom row its # 19
I also wanted to point out. from 1989 to 1996 the brake switch was the common failure for bmw's
the series it included were 318i, 525-540i, and all 7 series. if the fuses dont fix it.. its the switch
located under a panel u need remove on the drivers side on the steering collum

I would replace the Vehicle Speed Sensor (VSS) at the transmission 1st, also who advised the PCM (computer) was bad? a Jag dealer? I think they are guessing on that, computers rarely fail, maybe 2% of the time if that.

Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car
