strange noise from engine....
last night while out in the garage and noticed a strange very light whining, almost screeching noise coming from under the hood. It would happen every 30 seconds. It's hard to describe....maybe like a pressure release of something??....
this is after the car had been off and parked for over 1 hour. and it was not the usual air suspension when you open the doors.
has anyone else had this problem? should i be concerned?
i just thought it was strange for the car to still be making noises after being parked for over an hour...
thanks
