Screeching noise...

[crabAppple]

I hear this annoying noise when I am in the garage (mornings / evenings) and it stops for a second or two when I bring to park, then the noise is back on.
I hear the noise especially when I am near the wall or in between cars in the parking lot

There is no other problems performance or mileage wise...

I just completed a waterpump+cooling replacement in summer.

Any thoughts greatly appreciated!

-Thanks

[P.s I did a search on this, but I did not find any useful info.]

My Name is Bimmerfiver,

And I write once a week about pulley noises in our cars. You know, the pulleys and deflectors the rubber belts of our cars roll on.

I can only suggest to the owner of the car the noises aren't coming from the wall, the wall is merely a backboard for the noises which is somewhere in you car. I'd pop the hood and listen for it, have someone hit the gas to hear a change in pitch. I'd narrow it down and replace all pulleys, deflectors and belts. Chances are, it's them.

Regards,
Bimmerfiver

Does it change with RPMs?

My guess is Tensioner pulley. Is it more of a chirping noise?

check out my video below and let me know if it's the same noise.

I also have the same problem on my 02 530i. The chirping noise is only heard in less than a minute and usually disappear after shutting down and restarting the engine. Any help would be appreciated.
