I don't know if I should bring it to the dealer to have it check or not, but sometimes at stop lights, while waiting for the lights to turn green and no music on, i heard this low noise coming from the right side of the engine compartment; right under the dashboard. It sounds like something is pumping (very low). I can't figure out what could be running that causing the noise. Do you guys think it might be the brake pumps running? When i got home and park in the garage; i tried to listen for it but it stopped. So let me know what you guys think the noise is and should i worry or not.
thanks.
