WF13 - 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 2016

Model Line:

Panamera

Concerns:

DME control unit

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles.
New data records for the DME control unit are available for the affected vehicles.
The new data records optimise the engine's knock control, thereby making it more resilient in terms of
knock resistance, particularly for lower quality fuels.
Information
The measure to be carried out on the respective vehicle depends on the campaign scope to which
the vehicle is assigned.
Before carrying out the campaign, it is important therefore to check the campaign scope for the
vehicle by entering the vehicle identification number of the respective vehicle in PIWIS  'Vehicle information' menu:

Action
Required:

•

Scope 1: Re-programming DME control unit  Technical Information 'WF1300 Scope 1:
Re-programming DME control unit'

•

Scope 2: Synchronizing DME data and re-programming DME control unit  Technical Information 'WF1300 Scope 2: Synchronising DME data and re-programming DME control unit'

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.

Technical Information

16/15

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 4,601 vehicles in North America.
Information
If other programming campaigns that affect the same control unit and involve the identical
procedure are open for a vehicle in addition to this campaign, the affected control unit must only be
programmed once using the current PIWIS Tester software.
Only the latest campaign must be invoiced during warranty processing.
Other open programming campaigns that affect the same control unit and involve the identical procedure
must therefore no longer be carried out.
Proceed as follows in this case:
•

In PQIS, mark the campaign as 'cannot be carried out' with the reason “Modification of the
affected component”. The "Warranty relevance" flag must be activated in order to be able to set
a warranty claim and close the campaign.

•

A warranty claim must be submitted for the campaign in which 0 TU is entered as the specified
working time and no material items are specified.

Tools:

•
•

9818 - PIWIS Tester II with PIWIS Tester software version 15.400 (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:

Scope 1 — See Attachment “B”
Scope 2 — See Attachment “C”

Attachment "A": Work Procedure

Scope 1: Re-programming DME control unit
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.

Preliminary work
Carry out general preliminary work for control unit programming as described in  Workshop
Manual '9X00IN Basic instructions and procedure for control unit programming using the PIWIS
Tester'.

Information
The procedure described here is based on the PIWIS Tester II software version 15.400.
The PIWIS Tester instructions take precedence and in the event of a discrepancy these are the
instructions that must be followed. Deviations may occur with later software versions, for example.

PIWIS Tester - section on "Programming"'.
Specific information on control unit programming during this campaign:
Required PIWIS Tester software version:

15.400 (or higher)

Type of control unit programming:

Control unit programming using the 'Automatic
programming' function for the DME control unit.

Information
If the fault memories of individual control units (e.g. fault memories of the control units DME,
Adaptive Cruise Control (ACC), etc.) cannot be erased, proceed as follows:
•

Switch off ignition.

•

Disconnect the PIWIS Tester diagnostic connector from the diagnostic socket.

•

Lock the vehicle using the driver’s key.

•

Wait approx. 1 minute before unlocking the vehicle again.

•
