WD65 - Re-programming Power Electronics (Workshop Campaign)
Important:
CRITICAL WARNING - THIS CAMPAIGN INCLUDES STEPS WHERE SEVERAL CONTROL UNITS IN
THE VEHICLE WILL BE PROGRAMMED WITH THE PIWIS TESTER. IT IS CRITICAL THAT THE VEHICLE
VOLTAGE BE BETWEEN 13.5 VOLTS AND 14.5 VOLTS DURING THIS PROGRAMMING. OTHERWISE, THE
PROGRAMMING COULD FAIL RESULTING IN DAMAGED CONTROL UNITS. CONTROL UNITS DAMAGED BY
INADEQUATE VOLTAGE WILL NOT BE COVERED UNDER WARRANTY. THE TECHNICIAN MUST VERIFY THE
ACTUAL VEHICLE VOLTAGE IN THE INSTRUMENT CLUSTER OR IN THE PIWIS TESTER BEFORE STARTING
THE CAMPAIGN AND ALSO DOCUMENT THE ACTUAL VOLTAGE ON THE REPAIR ORDER. IT IS ALSO
ADVISABLE TO MONITOR THE VEHICLE VOLTAGE DURING THE PROGRAMMING VIA THE INSTRUMENT
CLUSTER. PLEASE REFER TO EQUIPMENT INFORMATION EQ-1105 FOR A LIST OF SUITABLE BATTERY
CHARGERS/POWER SUPPLIES WHICH SHOULD BE USED TO MAINTAIN VEHICLE VOLTAGE.
Model Year:
2014
Vehicle Type:
Panamera S E-Hybrid
Concerns:
Power electronics for the high-voltage system
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. A fault
can occur in the temperature monitoring system for the high-voltage system at low outside
temperatures due to a software error in the power electronics.
If this happens, the yellow warning message "Hybrid system fault" will be displayed in the instrument
cluster and the performance of the electric motor will be reduced by up to 50%. But the vehicle can still
be driven.
Action
Required:
Re-program the power electronics for the high-voltage system using the PIWIS Tester with software
version 13.130 or 13.160 (or higher) installed.
Information
The software required for re-programming the power electronics as part of this campaign depends
on the software that was previously installed on the PIWIS Tester.

* Please note that two online updates (13.130 and 13.160) are available on the Online Update server if
software 13.100 is installed on the PIWIS Tester. When the PIWIS Tester restarts after installing software
13.130, the following message will be displayed:
"The following DVD full update has to be installed before the online update can be performed again:
VG2-13.150"
If you have not yet received the DVD update containing test software 13.150, please ignore this
message.
This campaign cannot be carried out using PIWIS Tester software version 13.150. In this case, install
software 13.160 on the PIWIS Tester first.
** Following installation of software 13.130, software version 13.100 will still be displayed on the PIWIS
Tester desktop. The installed test software version 13.130 is shown in the "Version information" menu
from the release history (PIWIS Tester desktop > Information >> Version information >>> History >>>>
Update version).
Information
It takes approx. 5 minutes to program the power electronics.
Affected
Vehicles:
The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair. This campaign affects 303 vehicles in North America.

70A fixed voltage 13.5V to 14.5V. Refer to Equipment Information EQ-1105.
Attachment "A":
NOTICE
Fault entry in the fault memory and control unit programming aborted due to low voltage.
•
Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which
can result in one or more fault entries and the abnormal termination of the programming process.
Before commencing work, connect a battery charger or power supply - suitable for AGM Type batteries,
recommended current rating of 70A fixed voltage 13.5V to 14.5V to the jump-start terminals in the engine
compartment.
