Chirping sound : 2010 MZ 3 i-touring, 45,000 miles
 

For a year or so, I've noticed a sort of high pitched, very quick sounding, chirp that happens while I'm driving. It's not related to my struts or suspension, but I think it's coming from the engine, transmission or something like the air conditioning.

It just happens as I'm accelerating and it just does this quick "squeak" sound and stops. I mean it's fast and hardly noticeable if you have a radio on, but I heard it all last year and am hearing it now too and that makes me feel like it may be the air conditioning doing this sound.

Any thoughts or ideas? Or should I just take it to the dealership under warranty. But it will be nit-picky to describe the sound and have them hear it. I'm just worried that this is the initial sound of something bigger to come.

Help!

Did you find out what it is? I have the same problem

I have a similar noise coming from behind the Radio/AC panel. I've seen it as low as 20 mph mostly on washboard roads, particularly freeway. The slightest washboard roadway will cause the chiping

When I touch the center of the panel in between both radio tuning knobs, using the smallest amount of force imaginable, it's enough to stop the chirping sound. Smallest amount of force imaginable is equal to pushing an empty coffee cup along a frictionless surface, and still not having the coffee cup move (Yes, i know what frictionless means. Are you imagining this?).

Dealer is saying to pull the panel out and install some noise reduction foam around the panel. at a cost of 1 1/2hrs of labor.

Any suggestions? is it easy to remove the panel myself? Any special tools necessary?

Mine chirps when the ac is on I have 2012 mz3i sport and I have 110k on it now
