1991 525I bmw SERVICE LIGHT? Reset?norton 360
I bought my ''reset tool '' on ebay, some former bmw mechanic figured out a way to short out the OBD with a wire to reset the lights and the countdown timer. Cost me $1.25 and it worked. read the feedback 1st and buyer beware.

If you diconnect one of the battery cables it will reset the light
You must remove the negative battery terminal for at Least 5 seconds, in order to reset the computer.
It is controlled by the pcm-there is a special tool to perform the maintenance minder reset-you can buy it from a tool distributor(mac,snap-on,ect) or just go to the bmw dealership and ask to have it reset
It is my understanding that when service light comes on on most vehicles that it has to then be hooked to computer to be shut off.
not sure on the 91 but on the 93 and newer u need to use a reader to reset
look in the owners manual . it should explain how to do it .
Disconnect the negative battery cable for 3 minutes and reconnect it.
