It is probably the 'brain' going soft in the head. I had the same issue in the SDL. The antilock would kick in at every stop OR the light would come on and you would have no antilock function. You can try cleaning the sensors on the wheel hubs (front) like I did, but that did not help. I just went to the bone yard and picked up a "new" brain from a 560 SEL for $50.00 that is working correctly. They just plug in and you are good to go.
FYI a new computer costs over $2000.00
