i believe if its anything like my 2002 BMW 325ci that it would be in the trunk on the right. remove the black thing on the right (there should be 2 little plastic bolt looking things holding it down).
Its on the drivers side underneath the vehicle.....here is a diy for it. its for a 330ci, but its the same idea basically, and same location http://www.bmw330ci.net/maintenance/fuelfilter.php
Underneath the front passenger side area. Almost right below the front passenger seat. It's above a plastic plate with a few difficult screws.
