WE68 - Re-programming All-Wheel Drive 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 S Diesel/Macan Turbo

Concerns:

All-wheel drive control unit

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Transfer
gears with a control unit containing a data record that does not comply with current standards
were delivered to the dealer organisation.
An improved data record is available for the vehicles on which the transfer gear or PDK transmission,
which contains the transfer gear unit, was replaced during the affected period. This data record
optimises the responsiveness of the all-wheel drive system.

Action
Required:

Re-program all-wheel drive control unit.
Information
When the all-wheel drive control unit is programmed, the PDK control unit is also re-programmed
automatically. It takes approx. 5 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 11 vehicles in North America.

Tools:

•
•

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 14.800 (or higher) installed.

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.

Carrying out control unit programming
Information
The procedure described here is based on the PIWIS Tester II software version 14.800.
The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the
instructions that must be followed.
A discrepancy may arise with later software versions for example.
Work Procedure: 1

Re-program all-wheel drive 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:

14.800 (or higher)

Type of control unit programming:

Control unit programming using the 'Automatic
programming' function for the all-wheel drive
control unit.
Control unit  'All-wheel drive' > menu 
‘Programming’ >> function ‘Automatic
programming’.
Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.

Programming sequence:

The fault memory is first deleted during the
programming sequence. If the message appears
informing you that certain fault memory entries
could not be deleted, acknowledge the message by
pressing •>>“ and start control unit programming.
During programming, the PDK control unit
and the all-wheel drive control unit will be
re-programmed and then re-coded automatically.
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.):
