Bird chirping....wtf?!

[beem]

Hi all,

New problem surfaced today....whenever I start my car after a long stop (~2 hours), I can hear sounds like bird chirping (slow and fast pace sometimes) inside the car...it seems like coming from the passenger compartment side. I tried to listen to the same sound again from the engine compartment but there seems to be none. So, definitely its from the inside..

Anybody experience this thing before?

Do help!!

Thanks!

I think its time to sell it and go jappo.....

Re: Bird chirping....wtf?!

Yes, sounds like aircon...

Re: Bird chirping....wtf?!

I can still hear it with the aircond off....only when I off the engine, the sound disappear...and after the engine warms up...it disappear as well...

My car has got birds too. Yes it happens even when the a/c is off after you turn on the ignition to on. Nothing to do with fan belt cos' I can hear it even BEFORE starting the engine so long as the ignition is on. :furious:

Its some fan prob... i got the same issue. Apparently there is a fan at the glove compartment area. Its faulty... i just got mine replaced at arang recently....

I believe i took the last one there... just sent it in to pml and ask them to change for free if it is within warranty.... i think it is around $150.....

To me it sounds like cricket...

Re: Bird chirping....wtf?!

Thank you & best rgds,
John soh

Looks like everyone's got birds in the car! Just heard the same chriping, squeaking sometimes hissing sound in my 3.5yr old E46. Sound starts when car is cold, disappears when hot. Even before cranking engine, there will be that sound. After turning off aircon, the sound will still persist for a while. Sound is irritating but turn on the radio and you don't hear it.

Is it aircon fan or belt? Is it going to lead to something more expensive if I just ignore the noise?

It is the fan in the glove compartment that needs to be replaced....but apparently the sound disappaeared after bout 3 weeks.....so, I'm not changing it yet until the chirping sound reappears (touch wood)....

If it's indeed from the passenger side and cannot be heard from outside, then it should be the fan for the ECU. Behind the glove box, at the firewall, is the ECU for the E46. There is a fan that is attached to the ECU to keep it cool.

Try hearing it thru the passenger air con vent to see if it's from there...

Re: Bird chirping....wtf?!

I've got the exact same intermittent problem. Recently it's gotten worse than ever and is extremely irrtating. My first instinct was that it originated from a worn belt or bearing within the engine compartment but upon closer inspection, I realised that I could only hear it from within the cabin.

Spoke to Billy from J4C and he explained that it could be either the ECU cooling fan, or the Aircon Fan Bearing. Hope it's not too expensive to replace. :yikess:

I'll repost on the final verdict and cost once it's settled.

Re: Bird chirping....wtf?!

I think I am having this 'bird chirping' noise. As it comes about when the aircon fan is blowing... suspect is the fan blower... Car is an E46 318).

As I am v apprehensive of stripping the dashboard... can anyone please tell me where this blower is located... hoping that it's easily accessible.. and ez job..

Thanks!

Re: Bird chirping....wtf?!
