Compressor sound 2007 SL550
Hello guys,
Sometimes when I open the driver's door I hear a sound (like a compressor) for 6-7 seconds and it stops. Does somebody has experience that and what it is. Thanks.

You are probably hearing the SBC pump. When you open the door and the car wakes up, the pump will check the accumulator pressure and kick in to refill it if necessary. Pretty normal and nothing to worry about.
