Hey guys.

I wanted to ask more experienced users about possible source of the high pitch chirping sound. I didn't had that before, now when I slightly press gas pedal I hear this high pitch sound. Only happens in first moments of pressing pedal on idle. Also I hear this in a more constant way when I'm driving out of the garage (underground garage, so rpms are low and engine load is big). I've recorded it and even isolated the frequency so you would have easier task! Any ideas what can be source of that?

Video example

Thank you!

 

Could be a loose fan belt, same frequencies, but the fast chirp doesn't make sense....

 

High pitch when gassing from idle would seem to indicate a slipping belt as StealthTL noted. If the belt is okay then it could be the AC clutch slipping. Do you have the AC or defroster on?

 

Yes, but I've also tried with AC off, nothing changed.

 

it could literally be anything and without more detail this is just a guessing game likely not to be fruitful

you need a second person with one operating the throttle and the other at the front with the hood up trying to determine where the supposed chirping sound is coming from. Then you might have a foundation on which to build something useful on.

I would also suggest using an engine stethoscope to pinpoint the noise if it is not obvious.
