Help Needed with a part number
Hello guys,
I've been getting a code P12A2 on a 2009 Cayenne Base (3.6 VR6). After some troubleshooting, I narrowed it down to an air leak. The problem part though is hard to find, and I thought I'd ask here. The part I'm looking for is #6 in the attached diagram.
Any help is much appreciated!

Come Monday, I'll get in touch with the dealership, but was hoping to find it online as I finally got to the culprit of this code. Since everywhere I looked, the part wasn't identified, I figured I'd ask here, but no worries. I fixed it for now, but would prefer genuine parts.
Take care!

Hi, did changing this part resolve the P12A2 CEL issue?
Updates: 27 Oct 2019. Replaced my brake booster vacuum hose. So far no more CEL and zero fault code after clearing it.
Seem like my 2009 V6 cayenne P12A2 was due to vacuum leaks from all the split/cracks on the joints of the hose.
After replacing, engine running smooth and no more rpm bouncing up and down.
