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:

T2L5V

Programming sequence:

Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
The high-voltage battery control unit is
re-programmed and then re-codedautomatically during the programming sequence.
Do not interrupt programming and coding.

Programming time (approx.):

12 minutes

Software version programmed during this
campaign:

High-voltage battery control unit: 1200
Air-conditioning control unit: 1010
Following control unit programming, the software
version can be read out of the relevant control unit in
the 'Extended identifications' menu using the PIWIS
Tester.

Procedure in the event of error messages
appearing during the programming
sequence:

10 Create a vehicle analysis log (VAL) using the PIWIS Tester.
Mark the vehicle analysis log you have just created with the attribute "Final VAL" and return it using
the PIWIS Tester.
11 Complete the rework log and attach it to the warranty claim.
To do this, use the document "Attachment to TI 139/20: Rework log – Replacing high-voltage
battery".

Information
If the workshop campaign  Technical Information '9X00IN WKK5 Workshop campaign Re-programming air-conditioning and high-voltage battery control units' has not yet been carried out on
the vehicle, do not perform this workshop campaign.
When the programming mentioned above is performed, the relevant control units are programmed to the
current software version.
Campaign WKK5 must be closed by performing a recall update (warranty claim with 0 time units and no
material items) for the affected vehicles.

Information
After carrying out the repair measure described here, pay particular attention to the following:
•

Capacity of the installed high-voltage battery

The capacity of the high-voltage battery is set to 24 Ah following installation in the Panamera S E-Hybrid
and thus corresponds to the capacity of the high-voltage battery originally installed in the Panamera S
E-Hybrid.
•

Electric range display

When driving using electric power only in the "E-Power" driving programme, the internal combustion
engine may be switched on although the remaining electric range displayed is still up to 4 km (2.5 miles).
This is not a malfunction because the electric range is estimated. The electric range depends on driving
style, climatic conditions and the use of energy-intensive electrical loads. Please inform the customer
about this.

Invoicing:
Information
If there is a warranty-relevant defect, it can be invoiced using the existing high-voltage battery warranty.
In the event of an expired high-voltage battery warranty and an existing PAW, then if a technical defect is
the case (not caused by wear) an application for invoicing for ageing and wear must be completed. The
costs can also be invoiced under "External service" in the warranty claim following a successful test.
