Help: Squealing C63... long after shutdown w/ Video
So I went out to my car to get something, hours after last driving it, and it's making an odd squeal... constantly! It happens about every 30 seconds or so and I am dumbfounded.

Noise is once right at the beginning and again at about 28 seconds...

Any ideas? Video attached!

Interesting... I've never heard it before today. Oh well, chalk it up to another "normal" MB quirk I suppose!

AFAIK a lot of the cars make it, although some are higher-pitched than others and almost out of hearing range. From what I've been told, it's a normal noise created by some of the electronic "housekeeping" systems in the car that stay alive after you shut it off. Yours just happens to be lower-pitched and thus more audible.

My CLS63 doesn't squeal, but it does breathe after I turn it off. I go out and I hear sounds from it like it is taking a breath.

Either coolant system depressurizing (air being drawn in the coolant expansion tank as the coolant level drops), or alterantively the heater & A/C fan motor turning on at low speeds to dry out the A/C evaporator so you don't get mold build-up due to residual mositure in the system and the resulting musty cabin smell.
