WD17 - Re-coding Instrument Cluster (Workshop Campaign)
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:
2013
Vehicle Type:
911 Carrera 4 (991)/911 Carrera 4S (991)
Concerns:
Instrument cluster
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The
instrument cluster must be re-coded on the affected vehicles.
Action
Required:
Re-code the instrument cluster using the PIWIS Tester with software version 12.100 (or higher)
installed.
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

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/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 control panel in the ignition
lock with the original vehicle key if necessary.
Information
The procedure described here is based on the PIWIS Tester II software version 12.100.
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.
