Hello fellow members,
I have a couple questions that I hope someone here can answer. There is a little play in the main pulley at the front of the motor in my '06 550i. It has 2 belts attached. (It's the large pulley in the center of the attached photo.) What is that pulley? How serious is it that it has a little play? Any idea how much it would cost to fix it, if necessary? Car runs great. Thanks for your help.

Are you talking about your water pump (top/right)? Depending on if it has been replaced before how much it would cost. Have you tried tightening the 4 nuts on it? How many miles does your car have?

If tightening the pulley doesn't work (which I don't think it will), your pulley may be going bad. The rubber insulating both metal sections of the pulley is most likely disintegrating, causing the wobbling.
