Electrical buzzing/humming noise at night when parked.
So the other night I was wandering around my living room at 11 pm trying to figure out this weird buzzing noise I was hearing. It sounded like an electrical transformer or power supply, and I figured maybe it was related to the Christmas tree lights my wife had just installed. Nope, everything was unplugged from the wall. I went to bed still hearing the faint electrical whine...
My wife heard it the next day - she unlocked and then locked the E500 with the remote and said the noise stopped. She is convinced the noise was coming from the car while it was sitting in our carport. It is a 2006 and has just over 50,000 miles on it. It doesn't get driven much (as the mileage would suggest) but it is babied.
Any idea what this might be? I'm terrified it might be related to the suspension system, since everyone has always told me that is this Achilles' heel of this car (I bought it 5 years ago with 38k on the clock and all the dealer service records for every single scheduled service)
Thanks
PS - I'm getting ready to replace the valve cover gaskets - doesn't' seem like to big of a job, so if I need to devote time to working on it, this will be the time...

do you have a remote FOB with a panic button?

+1 on that.
The SBC makes some noise, but it doesn't go on for very long unless there is a problem. I don't have Airmatic, so I don't know about that, but I would think that if the compressor pump were running a lot, you would know.
