BMW uses little electromechanical sensors embedded in the rear passenger and front drivers brake pad. These are usually fool-proof and normally don't false alarm so I would say that either:

1. One of the monitored pads is truly worn down to the sensor
2. The connector that connects the sensor wires to the body cabling is corroded or intermittent. Try unplugging/plugging them a couple of times


Has the light been on since the brake job? I recently changed my pads, and the light came on afterwards. Turns out that the sensor connector was having problems making a good connection with the body cable. To figure out which is the problem, take an old sensor, cut the sensor off, strip the the two leads, and twist then together. Then take this and plug into the front (way easier to get to in an E39) and then the back to see which one is problematic. If you are handy with a meter, a worn sensor will measure open (very high resistance).

Hope this helps
