Fumes were initially observed by the #4 flight attendant while standing with myself in the forward galley.  Once I observed the odor; I went to the Captain and told him about the smell.  He proceeded to turn off the APU; and the smell of the odor dissipated.  He restarted the APU; and the odor returned.  He decided to try it once again by shutting it down and after a few minutes restarting it; and the odor was gone and again returned upon restarting.  The Captain called Maintenance and it was later decided that we would have to remove passengers and crew from the plane and take that particular aircraft out of service and get another plane for the flight.
A319 Flight Attendant reported a fumes event during boarding. The aircraft was removed from service after Maintenance was called.
