WF14 - 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:

Macan S/Macan Turbo

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.

Action
Required:

Re-program DME control unit.
Information
In addition to the DME control unit, the Gateway control unit is also re-programmed automatically. It
takes approx. 7 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 8,274 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 test 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:

Tools:

•

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.

•

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.
9818 - PIWIS Tester II with PIWIS Tester software version 15.200 (or higher) installed.

•
Work
Procedure:

See Attachment “A”.

Claim
Submission:

See Attachment “B”.

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.

Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
During the programming sequence, the DME
control unit - as well as the Gateway control unit
- will be re-programmed and then re-codedautomatically.

Programming sequence:

Do not interrupt programming and coding.
Once the control units have been programmed
and coded, the PIWIS Tester will prompt you to
switch the ignition off and then back on again after a
waiting time of approx. 10 seconds.
Programming time (approx.):

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 the fault memories of individual control units 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.

•

Plug the PIWIS Tester diagnostic connector into the diagnostic socket again and restore communication with the vehicle.

•

Read out the fault memories of these control units again and erase the fault memories 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.

Information
If the fault code 'C10ACF0 - Power steering limit stops not taught' is present in the fault memory,
teach the power steering limit stops.
•

Start the engine.

•

Turn the steering wheel fully to the left.

•

Turn the steering wheel fully to the right.
