Causes And Remedial Action
WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
The connector housing for the wire harness in the transmission is leaking. As a result, ATF leaks into the external wire harness.
In the event of a verified complaint, replace the wire harness in the transmission.
