Sounds like a fan spooling up? if so normal. There is a emissions related fan sound that activates about 15-20 seconds after start up and then turns off.

Sounds more like something in the front suspension. Not a fan but thank you for your reply. It baffles, is not detected by the computer yet I hear it.
