: : I have a Y2K 528i. At about twenty miles per hour I hear a brief whistle which arises from under the hood. As the driver I thought it came from the right side, but while riding as the passenger, it seemed to come from the left! It only occurs the first time one reaches 20 mph after start-up. Subsequent to that, the noise is absent. It occurs after cold- or warm-starts. It can't be reproduced by revving the engine. A BMW technician had no idea what it represented, but assured me it wasn't a sign of a significant problem.
: : Any clues?

Where is the PCV valve?
