Pressurizing Sound?
This is probably a stupid question, but I regularly notice a sound that sounds like something pressurizing in the engine compartment whenever I open any of the door of my S550 first thing in the morning. I can imagine it's some kind of pre-start process assuming I'm about to start the engine, but this is my first Benz and I'd like to know specifically what it's doing.


Thanks,
-MB
