WH08 - Re-programming Instrument Cluster (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 2017

Vehicle Type:

Panamera (971)

Subject:

Instrument cluster

Information:

There is a possibility that when you switch on the ignition, the displays in the instrument cluster
will not be activated on the affected vehicles.
As a result, no information will be displayed in the instrument cluster.

Remedial
Action:

Re-program the instrument cluster using the PIWIS Tester with software version 35.000.010 (or higher)
installed.

NOTICE
Use of a PIWIS Tester software version that is older than the prescribed version
•

Measure is ineffective



Always use the prescribed version or a higher version of the PIWIS Tester software for control unit
programming.

Information
During the campaign, the instrument cluster is re-programmed and then coded automatically.
It takes about 120 minutes to program and code the instrument cluster.
Affected
Vehicles:

Only the vehicles assigned to the campaign (see also PIWIS Vehicle information). This campaign affects 1
vehicle in North America.

Required tools
Tools:

•

9900 - PIWIS Tester 3 with PIWIS Tester test software version 35.000.010 (or higher) installed

Technical Information

31/17

Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of
70A fixed voltage 13.5V to 14.5V.

Preparatory 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 suitable battery charger or power supply, suitable for
AGM type batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V.
NOTICE

Completely flat vehicle battery
•

The break in communication in the vehicle system during programming causes safety-relevant functions,
e.g. driving light and brake light, to be switched on automatically. This results in an increased current
draw, which will run down the vehicle battery.



Before starting control unit programming, connect a suitable 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 and the vehicle
communication module (VCI). As a result, control unit programming may be aborted.



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

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

If the driver's key is not recognized in the vehicle, programming 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
On vehicles on which the fault described above has already occurred before this campaign could
be carried out, the instrument cluster must be re-activated temporarily before starting
programming. To do this, perform the following steps.
2.1

Switch off the ignition and remove the driver's key from inside the vehicle.

2.2

Remove fuse for the instrument cluster.
The fuse (7.5 A) is located in slot F2 of the fuse box at the left-hand side of the dashboard.

2.3

Wait approx. 10 seconds before re-inserting the fuse.

2.4

Place the driver's key with the back facing down in the front left storage compartment in the
centre console and switch on the ignition.

Information
The procedure described here is based on the PIWIS Tester 3 software version 35.000.010.
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.

Re-programming instrument cluster
Work Procedure: 1

Re-program the instrument cluster.
The basic procedure for control unit programming is described in the Workshop Manual 
Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the
PIWIS Tester'.
For specific information on control unit programming during this campaign, see table
below.

NOTICE
Use of a PIWIS Tester software version that is older than the prescribed version
•

Measure is ineffective



Always use the prescribed version or a higher version of the PIWIS Tester software for control unit
programming.
Required PIWIS Tester software version:

35.000.010 (or higher)

Type of control unit programming:

Control unit programming using the "Campaign"
function in the Additional menu on the PIWIS
Tester by entering a programming code.

Programming code:

Q9A2N

Programming sequence:

Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
The instrument cluster is re-programmed
and then re-codedautomatically during the
programming sequence.
The display in the instrument cluster is switched off
during programming. "bLF" appears on the digital
speedometer display. The ignition is still active in the
background.
The display in the instrument cluster will be switched
on again automatically as soon as programming is
complete.
Switch the ignition off and then on again only
when prompted to do so by the PIWIS Tester
because otherwise, programming will be interrupted and will then have to be started again.

Information
Brief breaks in communication between the control units during programming and coding can result
in fault memory entries in all control units in the vehicle system, which may impair vehicle functions.
In addition to the automatic deletion of the fault memories during programming, the fault memories
of all control units must therefore be read out again, checked and deleted as described below
after each programming and coding process.
2.1

Switch off the ignition and wait approx. 10 seconds before switching it on again.

2.2

Start the engine, leave it running for a short time and then stop it again.

2.3

Switch ignition off and then on again.

2.4

Restore communication between the PIWIS Tester and the vehicle.

2.5

Read out the fault memories and check stored fault memory entries.
For instructions, see  Workshop Manual '9X00IN Basic information and procedure for
control unit programming using the PIWIS Tester'.
If control units are found to have faults that are not caused by control unit programming,
these faults must first be found and corrected. This work cannot be invoiced under the
workshop campaign number.

2.6

Delete fault memory entries.

2.7

Select the 'Overview' menu to return to the control unit selection screen.

Concluding work
Work Procedure: 1

Switch off the ignition.

2

Disconnect the PIWIS Tester from the vehicle.

3

Switch off and disconnect the battery charger.

4

Enter the campaign in the Warranty and Maintenance booklet.
Information
The values for the Tire Pressure Monitoring (TPM) system may be lost during re-coding of the
instrument cluster.
If the Tire Pressure Monitoring (TPM) system is reset, the wheel electronics must be re-taught and
adapted to the system.
Preconditions and procedure for teaching the wheel electronics units:
•

Vehicle is stationary for at least 5 minutes.

•

Select the type of tires fitted (type and size) in the TPM menu in the instrument cluster. The
message "No monitoring. System is learning from 15 mph (25 km/h)" then appears in the multifunction display.

•

Drive at a speed of more than 15 mph (25 km/h) - ideally without stopping - until the tire
pressure values are displayed (learning time: less than 2 minutes).

The system learns the wheel electronics only while driving. Intermediate stops and deviations from
the described teaching procedure can result in a much longer learning time.
Teaching can be performed during the test drive or later while the customer is driving. Please inform
your customer about this if necessary.
