Lo and behold it fixes the problem but only because they removed the deposits from the rotor when they resurfaced it, not because it was warped.

I don't care much for BMW pads. They seem to be much more prone to leaving deposits on the rotor than other pads I've used. When these are up, I'm installing some Hawk HPS which have worked well in past cars.
Really? I have seen thousands of warped rotors. And yes, you can measure the runout.
