So I have recently acquired a s4 vert with 113k miles. I found one of the actuators sitting under my air intake, and have no idea where the other one is. The rod protruding from my lower intake mani is completely stuck and won't budge. Would I need to disassemble my intake mani's and all to get them to open up again? And right now I have a straight pipe, so they wouldn't open anyways. I found a write-up on how to wire them to the air pump and have them activate at specific rpm ranges. Any help is much appreciated!

 

kinda in the same boat as you. s5 with stuck aux port switch.
would you mind posting the link to that write up?

 

well the write up only pertains to the s4 because the 5/6 ports were activated via air pump from the factory i believe. heres a link to activate them electrically, but again I dont think it would help with the s5

In the new members tec section I have a thread on port valves check it out it is something to start on Trochoid has a short piece that might interest you in that thread also

 

take intake manifold off. clamp down on the pin with vice grips, and turn them. spray carb cleanr into the ports to loosen the carbon.
