WJ82- Re-coding Gateway Control Unit (Workshop Campaign)

Vehicle Type:

Panamera (971)

Model Year:

2017

Equipment:

Sport exhaust system (I-no. 0P8 or 0P9) with Sport Chrono package (I-no. QR5)

Subject:

Gateway control unit

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.

Information:

Due to a software error, the sport exhaust system can remain activated after switching the
ignition on and off again although it is shown as inactive in the Vehicle menu.

Remedial
action:

•
•

Affected
Vehicles:

Only the vehicles assigned to the campaign (see also PIWIS Vehicle information). This campaign affects
221 vehicles in North America.

Preparatory work
NOTICE
Fault entry in the fault memory and/or control unit coding aborted due to low voltage.
•

Increased current draw during diagnosis or control unit coding can cause a drop in voltage, which can
result in one or more fault entries and the abnormal termination of the coding process.



Before starting control unit coding, connect a suitable battery charger with a current rating of at least 90 A
to the vehicle.
NOTICE

Coding will be aborted if the WLAN connection is unstable.
•

An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle
communication module (VCI). As a result, coding may be aborted.



During control unit coding, always connect the PIWIS Tester to the vehicle communication module (VCI) via
the USB cable.
NOTICE

Control unit coding will be aborted if the driver's key is not recognized
•

If the driver's key is not recognized in the vehicle, coding cannot be started or will be interrupted.



Place the driver's key with the back facing down into the front left storage compartment in the center
console to guarantee a continuous radio link between the vehicle and the driver's key.

Information
The procedure described here is based on the PIWIS Tester software version 37.800.020.
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

Connect a battery charger with a current rating of
at least 90 A (e.g. VAS 5908 - Battery charger
90A).
First connect the positive cable of the charger to the
positive terminal  Jump-start terminals -2- and
then connect the negative cable of the charger to
the ground point for jump-lead starting  Jump-start
terminals -3-.
Then switch on the battery charger and start trickle
charging the battery.
