How much brake fluid do I need for flushing?

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.

The bleed valve on the driver side of the transmission and most accessible through the wheel well, right? What would be best - a stubby wrench or a longer one?

Also, I do not have PSM (I have no PSM off button so I'm assuming this means I don't) but I do have ABS - do I still need to do the Porsche diagnostic step?

Yes, it is way up on the transmission housing. I used a small closed end wrench and got it on by feel and then put the drain tube on without removing the wrench.

No need to open the ABS with the diagnostics. Just do a couple of hard brakes that engage the ABS after you have flushed everything.

You only need to activate the PSM/ABS during a bleed/flush if you have gotten air into the system, otherwise it is unnecessary.
