What's up everyone? I'm new to the board here.
I just wanted to pose a technical question to see if anyone has any input.

I have an '01 325i (39k) and I have been hearing this weird noise the last week or so. I hear this high pitched whine coming from the engine when I accelerate or rev the engine. You can't hear the noise when the car is ideling, but give it a little gas and it's there. I have read all kinds of posts about similar noises, but can't seem to pin point it. My local BMW dealer hasn't been of much help either - I get the same ol' "it's a quirk" or "we can't seem to pin point it".

Has anyone experienced something similar? Some ideas I thought of were: alternator, waterpump, belts...

Any imput is appreciated.
