WF53 - Re-programming All-Wheel Drive Control Unit (Workshop Campaign)
Important:
CRITICAL WARNING - This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).
Damage caused by inadequate voltage during programming is not a warrantable defect. The technician
must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document
the actual voltage on the repair order. Please refer to Equipment Information EQ1401 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
Vehicle Type:
Macan Turbo
Concerns:
All-wheel drive control unit
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a
possibility that the active all-wheel drive system Porsche Traction Management (PTM) on the
affected vehicles will deliver too much propulsion force to the front axle when taking off at full
load.
This can put greater strain on the inner joints of the front drive shafts under certain conditions, e.g. when
off-road mode is activated. This can result in noises or vibrations in the front axle area.
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 3,318 vehicles in North America.

Preliminary work
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: 1
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 - section on "Preliminary work"'.
Carrying out control unit programming
Information
The procedure described here is based on the PIWIS Tester II software version 15.700.
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.

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:
15.700 (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-codedautomatically.
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.):
5 minutes

Procedure in the event of abnormal
termination of control unit programming:
Repeat control unit programming by restarting
programming.

If this is not possible, restart the PIWIS Tester and
then execute control unit programming again.
