Brake Pad Warning Light

I have just 17k miles on my '04 C4S, and when I was driving the car immediately after washing it, I noticed the brake pad warning light was on. I'm not sure if it was on immediately after washing the car, or if it came on a short time later. The car has generally not been driven hard at all, so I'm a bit suprised that I would need new pads after only 17k miles. Even more surprising is that I've driven the car several times since then, and the light has never come back on. I'm not familiar with Porsche brakes, but on my Mini Cooper when the light came on, it was on permanently until I replaced the sensor wire. From reading Loren's instructions on how to replace pads, it appears that my C4S uses a similar type sensor wire (that must be replaced if the brake pad light was turned on). Has anyone had the same experience as me? Could washing the car somehow have turned on the warning light? Also, do also 4 wheels have sensor wires? On my Mini, there was only one sensor per axle. Thanks in advance for your help.

Thanks Loren. The light still has never come back on, so I'm guessing the water from washing the car somehow temporarily created a short in the circuit, which turned the light on. Are there 4 sensors on this car, or just two (one per axle) as with my Mini? Thanks again!
