I read it off or Dinan's ( a VERY big BMW tuner) site:

"In addition to the crankshaft issue, other problems can result from slowing down the accessories below their designed speeds, particularly at idle. Slowing the alternator down can result in reduced charging of the battery, dimming of the lights, and computer malfunctions. Slowing of the water pump and fan can result in warm running, while slowing of the power steering can cause stiff steering at idle and groaning noises. It is possible to implement design corrections and avoid these scenarios, but this would require additional components and/or software."

For the full story and why NOT to replace the CRANK PULLEY: http://www.dinanbmw.com/html/danger_...er_pulleys.htm
