Is that stuff you're seeing in Qsilver's post the stuff for the M62 engine? You've got the M54, so should ignore that stuff.
Also, on this project, my understanding is that this pump is working intermittently for you and your only real problem is an inability to successfully bleed the system, right? I recall a few threads, I think of yours, and may not be keeping them all straight here.
These aux pumps don't seem to fail much. Their use is to circulate warm coolant when the engine is off so you can still get heat inside the car. They of course are also helpful for bleeding the coolant. The main "problem" when they fail is that they make noise. If it were to seize permanently, you would probably never know or care unless you try to bleed the coolant.
So yes, maybe you have that, but you might have other problems in there too, and replacing this may not be the best first step.
