WE64 - Re-programming DME Control Unit (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 Turbo (991)/911 Turbo S (991)
Concerns:
DME control unit
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a
possibility that the oil temperature sensor will be incorrectly diagnosed as faulty when the
ignition is switched off and then back on again immediately on the affected vehicles due to the
current diagnostic setup for monitoring the oil temperature sensor.
As a result, the Check Engine light in the instrument cluster will be activated, although there is no fault
present.
Action
Required:
Re-program DME control unit.
Information
In addition to the DME control unit, the PDK control unit is also re-programmed automatically. It takes
approx. 12 minutes in total to program the control units.
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 1,730 vehicles in North America.
Tools:
•
•
9818 - PIWIS Tester II with PIWIS Tester oftware version 14.600 (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.

Technical Information
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 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.
Work
Procedure:
NOTE: VEHICLE VOLTAGE MUST REMAIN BETWEEN 13.5 AND 14.5 VOLTS DURING THE ENTIRE WORK

Re-program DME control unit.
The basic procedure for programming a control unit is described in the Workshop Manual - 
Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the
PIWIS Tester - section on "Programming"'.
Specific information on control unit programming during this campaign:
Required PIWIS Tester software version:
14.600 (or higher)
Type of control unit programming:
Control unit programming using the 'Automatic
programming' function for the DME control unit.
DME control unit >  'Programming' menu >>
'Automatic programming' function.
Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
During the programming sequence, the DME control
unit is re-programmed and then re-codedautomatically.
Programming sequence:
The PDK control unit is also re-programmed and
coded automatically.
Do not interrupt programming and coding.
Programming time (approx.):
12 minutes

Once you have read out the fault memories, delete the fault memory entries by pressing •F8“.
4
Press •F12“ (“Yes”) in response to the question as to whether you really want to erase all fault
memory entries.
The faults stored in the fault memories of the various control units are deleted.
Information
If there are still fault memory entries in individual control units, start the engine briefly and then switch
it off again. Wait for approx. 10 seconds before switching the ignition on again and re-establish the
connection between the PIWIS Tester and the vehicle. Then read out and erase the fault memories of the
affected control units again 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.
