I have a 1999 528i. the last couple days an odd issue has arose. When I start the car after its been sitting for a few hours (4+) there is a noise emitting from the driver side area of the engine compartment. If I turn the steering wheel in either direction the noise get abit louder. Its sort of a reeering noise. If you drive it aways (10mi or so) the noise goes away and doesn't return till the car has sat. I thought possibly the Power steering pump, but from what I can tell this car doesn't have one and it has a Rack/Pinion type setup instead, and I could be completely wrong on that also.
Anyone have ideas on this odd noise that has shown up?
