As well as checking the wheel sensors, have you checked the ABS relays (on
my E36 they're in the fuse box under the bonnet/hood). I had my ABS light
popping on from time to time over a couple of days, scheduled it to get
looked at by a mechanic, and when checking for a blown fuse on my windscreen
washer pump noticed that the gray ABS relay was loose - pushed it down
properly and it locked back in, and the ABS light hasn't been on since :)
