I just noticed that my 2000 is making a weird sound at start-up.

I can't really describe it in any other way than a duck quacking. It seems to last for only a few minutes, but it really sounds terrible.

I am in Dallas, TX where the winter has been really moderate and the S4 is parked in my garage every night. It is probably only in the 50's outside so I don't think it is the cold.

Any ideas? I wondering if I should take her in ASAP?

Thanks,
Rodney

additional info. . . the sound is rythmic, like something rotating and each time around the sound

I head a 'vaccum' noise in my car (cold) while adding washer fluid, anybody/ideas?

So if you open the hood, where does it seem to be coming from?

I had the same noise earlier this year. Would only happen when the car was cold in the morning and would go away after a few minutes. My fluid was very low. I added some and the noise went away. I will have the pump checked for a leak at my next service.

i'll RTFM tomorrow, but in case anyone is up.

It has a green cap. Unscrew the cap, there is a dipstick attached to it with min / max levels.
