Part# 94811005006

08 Cayenne S

It appears that my vacuum pump is only pulling 3/4 of the spec pressure, and there's some oil leaking around it. This may be causing a CEL with code P2404. So, I picked one up from my dealership this AM and plan to have a go at replacing it this weekend. I thought I'd start a thread for A) any advice or words of warning you might have on my way in and 2) an opportunity to document what I find, as I have haven't found any information on this task anywhere in the vast www. Wish me luck!

That wasn't quite as difficult as I feared. The parts diagram shows three torx attaching the pump to head. Mine were 8mm. I removed the plastics and pulled the hoses all to the side. From there, it was very difficult to access the bolts, but it was doable.

I know this is an old thread, but I just got a P2404 and was hoping that this piece needs to be replaced.

Edit: did this fix the error? What was the hardest part of this install?

Thanks! Chris
