As for reseting the service intervals, you have a couple options, first and cheapest is going to the Dealership and seeing if they will reset it for free. Second is purchasing the item you see below off ebay for $15. However shipping for mine took 3 weeks.
Sound like its from the top pass side and again it does not sound internal engine rattles....it sounds like an intake pulsating sound maybe its normal? Intake leak? I don't know maybe I should have it looked at. I know Mercedes, this is my 1st BMW. Thanks for the reply though.
