Yes... most German cars use either 7mm or 11mm bleed screws/nipples. You should use either a 12 point ring wrench or a flare tool - so you do not strip the bleed screws. You DO NOT want to use an open ended wrench.
IF it has been awhile since you last bled your brakes - you might use some sort of penitrating oil on the bleed screw first.
One other thing that I think everyone so far has taken for granted... is to state the (obvious) bleeding process. You want to first bleed the longest brake lines. So that is: Right Rear, Left Rear, Right Front, Left Front!
Using a pressure bleeder makes this whole process soooo much easier. But you do not have to use one.
Good Luck,
David
