S70 funny sound coming from under the hood
When the car is cold, a 
strange motor or something revs up and carries on for a minute or so, then slowly winds down. It hasn't had any effects on the engine (that I know of) but it's loud, and sometimes it will do this at a stop light, but not for as long. Anyone know what this can be?
