WE45 - 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 2010 up to 2014

Vehicle Type:

Panamera/Panamera 4/Panamera S/Panamera 4S/Panamera GTS
Panamera Turbo/Panamera Turbo S

Equipment:

•
•

Concerns:

DME control unit

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Certain
environmental conditions and the quality of fuel available in the market can cause combustion
residue to build up on the throttle valve on the affected vehicles over the service life of the
vehicle.

Emissions concept LEV2 (I-no. 162)
Emissions concept ULEV2 (I-no. 164)

This can impair the diagnostic function for the throttle valve and as a result, the Check Engine warning
light will be activated.
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 21,879 vehicles in North America.

Information
Exceptions during vehicle assignment:
•

In model year 2010 (A), only vehicles with the I-no. 750 are assigned to the campaign.

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 Testert 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:
•

Mark the campaign as 'cannot be carried out' with the reason “Modification of the affected
component” in PQIS. 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.

Work
Procedure:

See Attachment “A”.

Claim
Submission:

See Attachment “B”.

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.
