Vacuum hoses plugged up, what goes where and what’s missing

Recommended Posts

Hi Porsche gurus

I bought a 2004 Cayenne V6 3.2 , I have  error codes of insufficient air flow from secondary air injection pump to both bank 1 and 2, I’ve checked the pump and it seems to be working but when investigating I’ve noticed a hose about 300mm long coming from top of my manual gearbox near shifter cable connection is plugged off on the other end (where does that other end suppose to go? 

And I also found a plug stop on side of what I think is the exhaust manifold lhs of motor,

what is missing from here and where is it meant to go? Also could this be causing air flow issues as I’ve also noticed the more exhaust fumes are coming out of rhs exhaust pipe than the left,

any help would be much appreciated 

here are some pics

Looks like the aeration of the gearbox which must prevent water penetrating when wading through water puddles, the rubber gut may be raised a little higher and is not closed as you say, air pressure can still escape from the gearbox.

Thanks RFM much appreciated, at least I now that it’s not a modification on that hose, 

Would you know about the other plug on the other photo?

I'm hoping maybe someone can take a photo of their V6 to see what was there originally:)

Probably the venting of the front differential, the transfer case and rear diff. should also have one.
