2010 E550 Weird Front End Noise
Hello, new user here. I tried searching, but found nothing for what I was looking for.
Okay, my car was sitting in my garage. (Last driven 30minutes prior).
My sister goes into the garage to do an art project and came to find me saying that there was weird noising from my car. I went out to listen. It was coming from the front end, near the radiator. It sounded like when you blow a rubber balloon really hard that is makes a "chhhhh" sound. It would happen every 20 seconds and last about a second. I started the car up and raised it using the airmatic system. When I turned the car off, the sound disappeared. I am now waiting 30 minutes of the time of this post to see if it will occur again. Currently the car is sitting in the garage at the highest setting. The sound happened when it was in comfort setting. Just wondering what the sound was as I never heard it before. I know it isn't the blow off valve in the rear when you turn off the car and it shoots out a stream of air a couple seconds later.
-I live in Canada, weather outside is about -20C (-4F) and -10C in my garage, if that matters.
*Update 1 = Sound is back. Sound happens regardless of whether the car is locked or not. I have found a tiny hissing leak in the rear passenger side wheel well. It sounds like its coming from the tire, will stop by a shop tomorrow to see if any holes are in it. Also if the car is sagging on that side tomorrow morning, guessing I need to buy a new strut?

It could be a loose connection on the air line as well. Doesn't necessarily mean the air bladder is bad. If there is a leak it should be sitting on the tire in the morning.

I kinda decided not to pay attention to it, and it is still happening once in awhile.
