wet foot driver side - try to identify identity of leaking component 06 CTTS

Recommended Posts


I am chasing causes for wife's complaint about water dropping on the right foot on the drivers side during cornering on the 06 Cayenne Turbo. I already cleaned out the AC drain on the passenger side, but the leak seemed to remain predominantly on the driver side. I took out the entire driver's carpet (was all wet), and dried for a day in the sun. For a few days I subsequently removed parts, and finally I can see that he water is likely released from the seam between a plastic housing and an aluminum body (some heat exchanger?).


I circled this region yellow in the attached picture. My question is, what is this part, and whether there is a way to remove w/o having to deal with dash board removal - or alike. Thanks,

From the Pelican Parts Forum


"The heater core is removed from the under the drivers side dashboard. It is located right in the center of the vehicle above the transmission tunnel underneath the dashboard. The relay carrier, Immob CU, and Electrical CU must be removed, hidden behind the drivers side lower dash panels. Hope that helps! " Fredn5

Hi Fredn5(churchvb)-

thank you for the guidance. Should help. Ordering it now, and it looks like one more of the many little projects the older the car gets. But also think it still deserves that attention :) 

Thanks again!
