Sup Everyone

I bought my Red 01 CL-S about 2 months ago and it's awesome had really low miles and body and engine is great condition. Now I have been noticing a low grinding sound coming from the engine area when I first start-up and pull out of a parking space. At 1st I only heard it after the car has been sitting overnight now I hear it all the time, even if it's only been sitting for a few minutes.

Is this normal? I talked to my brother who is a mechanic and he told me it might be the ABS adjusting but he has not heard the sound.
Has anyone else out there heard the same sound?
I've looked through a few of the posting sections on here and have not seen any post addressing this issue.

Any help will be greatly appreciated.

Yeah, it could be.

The ABS system will make that buzzing/grinding noise twice right after you first start the car. I don't have the owner's manual in front of me, but the two speeds it does it at is when you first hit 5 mph, and the second time when you first hit 15 mph.

The buzz itself is some kind of self-checking procedure that the ABS system does.
