Default Compressor Runs and Popping Sound

Sometimes when I go to the garage I here the air compressor running, and a popping sound like something is moving. This happens huors after the car has been drivin. Do I have a leak in the suspension somewhere, and has anyone else experienced this?

I don't know about popping. Cars regularly make pinging type sounds when cooling down. The sound you hear is the fuel pump depressurizing or something. It's actually mentioned in the manual, I forget exactly what it is. It's normal.

Thanks. As far as the popping, it is not the metal cooling down. The other sound could be the fuel pump but sounds like a typical air compressor for adujsting the ride hight. I'll ask when they do my B pillar. Anyway, I don't think it is anything to worry about at this time.
