WD39 - Re-programming Instrument Cluster (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:

Instrument cluster

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles.Due to a
software error in the instrument cluster, the departure time set in the departure timer may be
read incorrectly while the high-voltage battery is charging.
As a result, there is a possibility that the vehicle’s high-voltage battery may not be fully charged by the
required departure time.

Action
Required:

Re-program and code the instrument cluster.
Information
It takes about 19 minutes to program the instrument cluster.

Information
When the instrument cluster is re-coded, the individual settings implemented in the instrument cluster
by the customer will be lost and are reset to the default values of the country version that applies to
the vehicle.
After carrying out the campaign, therefore, please inform your customers that personal settings
they have implemented in the instrument cluster will have to be set again and provide them with any help
and support they need for setting the relevant options.
This affects the following settings in the Vehicle menu, for example:

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 only one VIN, a PAG supplied marketing vehicle currently touring the U.S.,
VIN WP0ZZZ97ZEL040111.

Tools:

9818 - PIWIS Tester II with test software version 12.600 (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.

Work
Procedure:

See Attachment “A”.

Claim
Submission:

See Attachment “B”.

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.
1

Disconnect electric plug connection for the fan
blower  Disconnecting electric plug connection
-1- ( Disconnecting electric plug connection
-arrow-) to prevent the blower from coming on
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.

Disconnecting electric plug connection
2

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.

3

Switch on the ignition using the original driver’s key. On vehicles with “Porsche Entry & Drive”, do
this by replacing the control panel in the ignition lock with the original driver’s key if necessary.

4

9818 - PIWIS Tester II with test software version 12.600 (or higher) installed must be connected
to the vehicle communication module (VCI) via the USB cable. Then, connect the communication
module to the vehicle and switch on the PIWIS Tester.

Carrying out control unit programming
Information
The procedure described here is based on the PIWIS Tester II software version 12.600.
The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the
instructions that must be followed.
A discrepancy may arise with later software versions for example.
