Looks like http://www.baumtools.com/bmw_catalog_2006.pdf has the slide hammer tip with M12x1.0 thread PN W910A on page 7. They don't seem to have the entire slide hammer though. You can probably rig something up though.
According tp the TIS, BMW PN's are 11 3 050 for Rocker Shaft Drift and 11 3 060 for slide hammer. Both are made by SWZ.
