How much brake fluid do I need for flushing?

I always have 2 quarts/liters ready for flushing and 1 for regular bleeding. Otherwise you are right on. Finding the clutch bleed valve and getting a wrench on it is hard the first time.

If you have ABS and PSM you want to get both of them to engage after you have flushed, just to make sure that you get fresh fluid into them. The "proper" way to do it is to open them up using the Porsche diagnostics before flushing.
