Thanks guys. I agree the FSR is a lot easier to replace but it doesn't explain the squealing or squeaking. I don't ever have any of the FSR symtoms like pulsating or battery drain so I am fairly confident the motor is failing. Seems to be a common problem.
I found FCP Euro has this one on clearance for just under $200 so even though I don't have $20 in my BMW slush fund, my wife reminded me that summer is almost here and we needed to make a sacrifice and get this coming.
