when my car is in the garage, it makes high pitched beeping sounds (for couple of seconds and stops and over and over again) freaks me out. does anyone else notinced that?

My E350 does the same thing too. Can't figure out why it is doing that

My 08 E350 does same thing.

I able to find out that it does it if I leave lights on "Auto"
I was able to get rid of sounds if I turn lights to "off" position before
switching engine off.

My '08 E350 does not make these sounds that I can hear.

I just noticed the same thing -- low volume beeping sound that seemed to be coming from the car. At first I thought it was from a cellular phone or something. Definitely strange. The headlights are set to auto, so maybe that's it.

I hear the same noise. Just recently noticed it when the car past 13k miles.

If you have air suspension it will level itself off during random times while in the garage!!! They computers inside the car constanly monitor what is going on around it and that is what could be the high pitched whine...or if you have keyless go it makes a really high pitched whine noise....

Nice car, Alek!! Maybe it's the ghost of Mercedes Past. Seriously though,I get the same noises, I think the car is settling into stationary mode...

If it made strange noises when you drive than you would have to worry about it. But at stationary, just the car computer adjusting itself.

Mine does it too sometimes. And I keep the lights on "auto" all of the time. Now I'm going to monitor it and try turning the lights to "off." Thanks for posting.

Your car has a mind of it's own. When you pull the key out and lock it it is still awake...
