Ok - good on not removing the hydraulic lines. Like I said one person did do this so I had to eliminate it.
The weak battery usually throws a fault light on brake application that clears on restart. But like I said that is typical, there could be other modes related to weak batteries we haven't seen yet.
Interesting that it is only at low speeds. The bent rotor theory would cause a vibration at speed and could cause the grabbiness at low speed so I don't really suspect that. Really need to check with a dial indicator as run out of as little .005 inch can cause a problem. The manual does not specify a runout limit.
I do stand corrected on the front ABS senor - it does have a gap spec. 0.0039 to 0.0669 inches so check that as well. If your "dent" falls out side that range the system will most likely detect it but I am not sure if it will react to one missing pulse. I think it looks for a change in speed and one pulse may not be enough for it to detect and react to anything.
Also did you install the axle properly? Tighten the axle nut to spec and compress the forks several times before tightening the pinch bolts. I, for the life of me, don't see why this is important given the tight fit of the axle in the forks but BMW felt it was important to put in the manual. Also the torque on the calipers.
Other than that I guess you could try another wheel assy as Dick suggested or just replace the ring ($66.00 part). I looks like you could remove it and lay it face down on a hard surface and hammer it back out with a drift as it is just stamped steel. I would give that a shot.
