So I am getting CEL of P2189 i have a 2005 Cayenne Turbo and i know it is related to:

Possible fault cause

- Incorrect main charge signal

- Intake air system leaking

- Fuel pressure too low

- Volume supply of fuel pump too low

- Mechanical fault in injection valves

- PCV valve leaks

- Cap of oil filler neck leaking

- Leaks in exhaust system

- EVAP canister purge valve mechanically faulty (hangs open)

- EVAP canister purge valve output stage faults

Would it be possible for you to post a diagram of where these are located on the engine and part numbers? I think I could fix it from there if I just knew what I was looking for and where its located. Thank you so much!!!

Did you check the oil filler cap? and the crankcase ventilation hoses?

- those are a common cause of this fault.

Here are the diagrams of parts locations:

Thank you for the diagrams, I checked the Filler Cap and it appears to be on tight, I also replaced the turbo breather pipe that is located behind the manifold (part number 948 107 215 52) becuase that was broken. I can't seem to find any other leaks in the system. I dont want to keep replacing hoses if they are fine becuae those hoses are much more expensive than they should be... but its a Porsche so it doesn't suprise me.

955-104-287-01 Sealing ring -- US MSRP $7.58

You might have to take the cover off to replace it easily.

I purchased the Sealing ring, but i cant figure out where it goes, i can only find it referenced in the V6 engine. post-74057-0-49386900-1350316646_thumb.g #32

:oops:

My apologies -- I gave you the V6 part number not the V8 part number.

The correct part number is: 948-105-934-00 Gasket -- US MSRP $16.58 each (2 required)
