Information
Prerequisite: Ensure the PIWIS Tester is updated to v42.950.032 (or higher).
1. DO NOT PERFORM A VEHICLE HANDOVER OR PDI ON THE VEHICLE AS A FIRST STEP.
2. WRM0 Stop Delivery – Update to software network VR28.11. This must be performed before conducting
a Vehicle Handover or PDI.
3. Vehicle Handover is now possible
4. WRP6 Stop Delivery - Replacing electric power distributor control unit (J1282)
5. WRP7 Stop Delivery - Replacing adhesive strips for sensor on left and right charge port door
6. WRN2 Stop delivery - Checking parking lock and replace drive unit if necessary
7. WRN1 Stop Delivery - Check rear axle drive and replace if necessary
8. WRP8 Workshop Campaign - Checking sliding roof and replacing control unit for sliding roof, if necessary
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.

Action:

•
•
•

Update control units in the vehicle network to network release VR28.11.
Execute repair script on the Infotainment main control unit (HCP3) using a USB memory stick
Repeat vehicle commissioning if it already occurred before the update to network release VR28.11.

Affected
vehicles:

Only vehicles assigned to the campaign (see also PCSS Vehicle Information).

Required parts
Information
As part of the update to the VR28.11 software network, a repair script must be run using a USB memory
stick on the Infotainment main control unit (HCP3).
Pay particular attention to the following:
•

An empty USB memory stick (e.g. Part No. V04014999WW000) with a maximum storage capacity of
32GB must be used for the update

•

The USB memory stick must be formatted to the file system FAT32

•

The repair script required for the update must be downloaded via PiUS under Navigation data (Region
can be ignored)and saved on the empty USB memory stick

•

The repair script to be installed on the USB memory stick in PiUs must have the following meta data:

•

Part number: V04007009BS

•

File name: srm_repair_20240719T142743_prod.zip

* Every Porsche Center responsible for looking after a vehicle affected by the campaign is provided with one
USB memory stick for programming. Therefore, the USB memory stick must only be ordered once, to remain
at the supervising Porsche Center as a tool.

During the guided update procedure on the VR28.11 software network, a repair script must be run using a
USB memory stick on the Infotainment main control unit (HCP3).
To do this, plug the USB memory stick into the vehicle as instructed by the PIWIS Tester and note the
display on the central display. After successful execution of the repair script (display on the central display
"completed successfully"), remove the USB memory stick from the multimedia interface. Then continue

Information
During the update process, all displays in the vehicle (instrument cluster, central display and passenger
display) are occasionally switched off. Programming nevertheless continues. The ignition sequence must
not be changed.
If WiFi coverage is insufficient, the connection between
the PIWIS Tester and VCI can be interrupted (battery
charge indicator inactive on the Tester display at the top
right). The vehicle will nevertheless continue programming
independently. In the meantime, no entry must be made
on the PIWIS Tester, and the programming must not be
restarted. In such a case, the progress of the update can
still be followed inside the vehicle via the central display by
activating the "Messages" tile.
