Help identifying the VDI
OK i was looking over my s5 manifolds today trying to find the vdi where im supposed to wire an air pump too, but i dont se anythign on the maniold that moves at all. I assume it was removed cause there is a hole about the thickness of a pen going through the manifold. Am i right and how can i identify ti and reassemble it? A close pic would be appreciated.
Also I am using an rpm switch and pump to open my 6 ports and will also need one to opwn the vdi. WOuld it be horrible if i used the saem pump set ata medium rpm to open them at the same time? Like the 6 ports a bit later and the vdi a bit earlier say around 4500?

it's right underneat the dynamic chamber, on the manifold you should see a big round cylinder cast into it by the runners and follow that back and you'll find the actuator arm on the outside.

I've been reading your posts as of late, and it's becomming very obvious that you need to do some basic research before you post.
Check the factory service and Haynes manuals. Both include very detailed descriptions and pictures of the VDI manifolds. There are threads in the archives which clearly show the manifolds. Many pictures of S5 engine bays have been posted.
This is all very basic stuff that you need to pick up on.

AARON, you may be right but i do search before I post and there are some really retarted posts on here that deserve your attention far more than mine.
Any answers about the timing of the 6ports/vdi?

Why don't you look in the FSM before posting? Seriously, how hard is that?
You need to use two rpm switches or you're wasting your time. The S5 ECU activates the 6PI system at 3850rpm and the VDI system at 5200rpm. Picking one point in the middle for both will throw away most of the gains from these two systems.

No, you only need one pump, feeding two solenoids. One rpm switch operates the pump and the 6PI solenoid and the other rpm switch operates the VDI solenoid. Look at the stock 6PI/VDI plumbing in the FSM and copy that.
