WF86 - Re-programming DME Control Unit (Worksohp Campaign)
Important:
Critical Warning — This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5
volts and 14.5 volts during this programming. Failure to maintain this voltage could result in
damaged control unit(s). Damage caused by inadequate voltage during programming is not a
warrantable defect. The technician must verify the actual vehicle voltage in the PIWIS Tester
before starting the campaign and also document the actual voltage on the repair order. Please
refer to Equipment Information EQ1401 for a list of suitable battery chargers/power supplies
which should be used to maintain vehicle voltage.
Model Year:
As of 2012 up to 2016
Vehicle type:
911 Carrera (991)/911 Carrera S (991)/911 Carrera GTS (991)
911 Carrera 4 (991)/911 Carrera 4S (991)/911 Carrera 4 GTS (991)
911 Targa 4 (991)/911 Targa 4S (991)/911 Targa 4 GTS (991)
Country/Market:
USA (C02)
Canada (C36)
Korea (C39)
Equipment:
Porsche Doppelkupplung (PDK) (I-no. 250)
Subject:
DME control unit
Issue:
Due to a software error in the DME control unit, there is a possibility that diagnostic information
for the PDK control unit will not be further processed correctly by the DME control unit on the
affected vehicles.
To prevent this from happening, the DME control unit must be re-programmed using an updated data
record.
Remedial
action:
Re-program the DME control unit using the PIWIS Tester with test software version 16.300 (or higher)
installed.
NOTICE
Use of a PIWIS Tester test software version that is older than the prescribed version
•
Measure is ineffective

Always use the prescribed version or a higher version of the PIWIS Tester test software for control unit
programming.

Technical Information
Affected
Vehicles:
Only the vehicles assigned to the campaign (see also PIWIS Vehicle information).
Tools:
•
•
9818 - PIWIS Tester II with PIWIS Tester test software version 16.300 (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.
Preliminary work
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 starting control unit programming, connect a battery charger or power supply, suitable for AGM
type batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V.
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.
Procedure:

Carrying out control unit programming
Information
During DME control unit programming, the PDK control unit is also re-programmed and coded automatically.
The instrument cluster is also re-programmed on the following vehicles:
•
Model year 2012 and 2013 vehicles
•
Model year 2014 vehicles with I-no. IY1 (vehicles manufactured before week 45/2013)
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:
Procedure:
•
Lowering of door mirror on passenger's side during parking manoeuvres
•
Locking settings
•
Light & Visibility settings
•
Units (kilometres/miles, Celsius/Fahrenheit, ...)
