WF17 Re-coding 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:
As of 2014 up to 2015
Vehicle Type:
911 GT3 (991)
Concerns:
Symbol for the engine warm-up phase in the instrument cluster
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Due to an
error in the PIWIS Tester II software versions 14.600 to 14.900, the symbol for the warm-up
phase is no longer activated on the multi-function display after coding the instrument cluster
on the 991 GT3.
As a result, the driver is not alerted to the fact that the engine has not yet reached operating temperature
and the maximum engine speed is therefore limited to 7,000 rpm.
Based on the usage period of the defective software in the Porsche dealerships, the vehicles assigned
to the measure include vehicles on which either campaign AE01 was carried out or the repair history
indicates that the instrument cluster was programmed or coded in the period from October 15, 2014
to January 20, 2015.
Action
Required:
Re-code the instrument cluster so that the symbol for the warm-up phase is activated correctly again.
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 7 vehicles in North America.
Tools:
•
•
9818 - PIWIS Tester II with PIWIS Tester software version 15.000 (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.

NOTICE
Coding will be aborted in the event of low voltage.
•
Increased current draw during diagnosis can cause a drop in voltage, which can result in one or more fault
entries and the abnormal termination of the coding process.

Before commencing work, connect a suitable battery charge 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.
NOTICE
Coding 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, coding 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 coding will be aborted if the vehicle key is not recognized
•
If the vehicle key is not recognized in vehicles with Porsche Entry & Drive, coding cannot be started or will
be interrupted.

Switch on the ignition using the original vehicle key. To do this, replace the dummy key in the ignition lock
with the original vehicle key if necessary.

Work Procedure: 1
Connect a battery charger with a current rating of at
least 40 A.
First connect the positive cable of the charger to the
positive terminal of the battery and then connect the
negative cable of the charger to the ground point for
jump-lead starting  External power connection.
2
Switch on the ignition using the original driver's
key.
To do this, replace the control unit in the ignition lock
with the original driver's key if necessary.
3
9818 - PIWIS Tester II with software version
15.000 (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.
4
On the PIWIS Tester start screen, call up the  'Diagnostics' menu and select the vehicle type  '911'  '991'.
