Aux pump bleed

I've looked for a definitive answer to the question of if E53 4.x owners can bleed their coolant systems with the aux pump and haven't found it. It seems newer cars can do this, but I'm still not sure about older E53s.

Can anyone confirm (or not) that the E53 4.x can be bled via the aux pump, and the procedures? I'd love to get my coolant system air-free before first start of the new motor.

Thanks much - Brian
