Binder - Advanced Technical Information
This bulletin replaces ATI bulletin Group
9, #0900, dated 4-23-09.

Models:

Cayenne/S/GTS/Turbo (2nd Generation)

Model Year:

2003-2010

Information:

Cases of main wiring harness corrosion in Cayenne models in the driver’s footwell.

Customer Complaint: Vehicle almost always comes in as a breakdown with one of several complaints:
> Key not recognized message in dash display
> Will not crank over
> Stuck in park

Note!
It is absolutely vital that breakdown vehicles are marked in the PQIS system as such, including all
cases of tow-ins, Roadside Assistance and customer home visits. Previously this has not been
done and therefore has gone unnoticed by the quality departments within the Factory.
Remedy:

Check and perform this work procedure on MY'09 Cayennes coming into the dealership for
breakdowns with these symptons. See Work Procedures, Page 2

Warranty Procedures: See Page 4
