WD33 - Re-coding TPM Control Unit (Workshop Campaign)

Note:

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:

2014

Vehicle Type:

Panamera / Panamera 4 / Panamera Diesel
Panamera S / Panamera 4S / Panamera GTS / Panamera S E-Hybrid
Panamera Turbo / Panamera Turbo S

Concerns:

Tire Pressure Monitoring control unit
(referred to below as “TPM control unit”)

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. High speeds
(> 165 mph/270 km/h) can cause an implausible warning message due to a software error in
the TPM control unit.
If this happens, the warning message “Tire pressure! Reduce speed” appears in the instrument cluster,
although no pressure loss has occurred in the tire.

Action
Required:

Re-code the TPM control unit using the PIWIS Tester with software version 12.600 (or higher)
installed.

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 449 vehicles in North America.

Tools:

•

Work
Procedure:

See Attachment “A”.

9818 - PIWIS Tester II with PIWIS Tester software version 12.600 (or higher) installed.
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.

See Attachment “B”.

Attachment "A":
NOTICE
Coding will be aborted in the event of low voltage.
•

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



Before commencing work, connect a suitable battery charge or power supply - Suitable for AGM Type
batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V to the jump-start terminals in
the engine compartment.

NOTICE
Coding 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, coding 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 coding will be aborted if the vehicle key is not recognized
•

If the vehicle key is not recognized in vehicles with Porsche Entry & Drive, coding cannot be started or will
be interrupted.



Switch on the ignition using the original vehicle key. To do this, replace the dummy key in the ignition lock
with the original vehicle key if necessary.

Information
The procedure described here is based on the PIWIS Tester II software version 12.600.
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.
