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.
Software currently installed
on the PIWIS Tester:
Software to be installed on the
PIWIS Tester in order to carry
out this campaign:

* 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.

9818 - PIWIS Tester II with test software version 13.130 or 13.160 (or higher) installed
Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of
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.

Disconnect electric plug connection for the fan blower to prevent the blower from coming on during
control unit programming.
NOTICE

Control unit programming will be aborted if the Internet connection is unstable.
•

An unstable Internet connection can interrupt communication between PIWIS Tester II and the vehicle
communication module (VCI). As a result, control unit programming may be aborted.



During control unit programming, always connect PIWIS Tester II to the vehicle communication module
(VCI) via the USB cable.

NOTICE
Control unit programming will be aborted if the vehicle key is not recognized
•

If the vehicle key is not recognized in vehicles with Porsche Entry & Drive, programming cannot be started
or will be interrupted.



Switch on the ignition using the original vehicle key. To do this, replace the original vehicle key in the
ignition lock with the plastic key fob if it was previously removed at the start of this procedure.

Work
Procedure:

NOTE: VEHICLE VOLTAGE MUST REMAIN BETWEEN 13.5 AND 14.5 VOLTS DURING THE ENTIRE WORK
PROCEDURE.

Disconnect electric plug connection for the fan
blower  Disconnecting electric plug connection
-1- ( Disconnecting electric plug connection

during control unit programming.
Having the fan on and the associated increased
current draw can cause a drop in voltage, which
can result in abnormal termination of control unit
programming.

If the fault memories of individual control units (e.g. fault memory of the DME control unit, Adaptive Cruise
Control (ACC), etc.) cannot be erased or if the red warning message "Hybrid system fault" does not go out
in the instrument cluster after programming is completed successfully, proceed as follows:
•

Switch off ignition.

•

Disconnect the PIWIS Tester diagnostic connector from the diagnostic socket.

•

Lock the vehicle using the driver’s key.

•

Wait approx. 1 minute before unlocking the vehicle again.

•

Plug the PIWIS Tester diagnostic connector into the diagnostic socket again and restore communication with the vehicle.

•

Read out the fault memories of these control units again and erase the fault memories separately.

If control units are found to have faults which cannot be erased and are not caused by control unit
programming, these faults must be found and corrected. This work cannot be invoiced under the
workshop campaign number.
