WPJ5 - Update to Software Network VR10 (Workshop Campaign)
Revision:
This bulletin replaces bulletin Group 9 118/23 WPJ5, dated August 22, 2023.
Model Year:
2024
Model Line:
Cayenne (9YA/9YB)
Concerns:
Software update (software network VR10)
Cause:
Software optimizations are available for various control units for the Cayenne.
An overview of the new features that will be implemented with the software update can be found in the
enclosure under  Technical Information 'Overview of new features of the software update'
Re-program the control units with the latest PIWIS Tester software release.
Minimum requirement: Release 42.100.060 or higher. It is recommended to use the latest PIWIS
Tester software version for optimized execution of all tester operations and backend system
communications.
Actions:
•
•
Checklist:
Due to the high number of programming steps incorrectly carried out as part of the last software
update, a checklist was created to improve the overview of the work to be carried out. The checklist
must be completed, signed and attached to the PQIS quality line in the PCSS.
For checklist, see  Technical Information 'Checklist'
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information)
Required tools
Tools:
•
•
Battery charger with a current rating of at least 90 A, e.g. VAS 5908 battery charger 90 A

Update to software network VR10
Work
Procedure:
Information
Before starting programming, the battery charger must necessarily be:
•
Operated in SUPPLYMODE with a 14.6 Volt setpoint and 90 A current limit.
Verify the settings of your VAS 5908 power supply before applying power to the vehicle.
NOTE: The vehicle electrical system must never exceed 14.8 Volts. Use a quality DMM/DVOM to verify
voltage at the power supply connection points of the vehicle.
Electrical resistance in the power supply cables and the clamp connection points greatly affect power
supplied to the vehicle. For example, resistance of 0.015 Ohm in the cable set results in a 1.35 V drop in
the cables when a 90 A current is required. Perform a CABLE CHECK / Cable Compensation periodically,
approximately once per month, to ensure proper power supply.
•
The vehicle must be on a level surface.
•
Air suspension must be at normal level.
•
There must be an active PPN connection.
1
The basic procedure for control unit programming is described in the Workshop Manual 
Workshop Manual 'Basic Instructions and Procedure for Control Unit Programming Using the PIWIS
Tester'.
Place vehicle key remote in rear of left cupholder (emergency start position).
2
After the “Creating Documentation Updates” process, the integration test is started automatically.
The result must first be ignored.
3
Create a Vehicle Analysis Log (VAL) - Service (Serv.) VAL using the PIWIS Tester - Additional Menu
[F7]. Mark the vehicle analysis log you have just created with the attribute “Pre-VAL” and after
carrying out the campaign, return it using the PIWIS Tester.
4
Put the PCM & Connect in Private Mode before starting the programming
5
Update software for various control units to VR10.
For specific information on control unit programming during this campaign, see the table
below.
Information
If programming or coding is aborted, the programming must be carried out again. In order to be able to
invoice for the new programming in scope 2, a screenshot of the general overview must be created at
the end of the programming.

Information
As of the 2024 Cayenne, two separate Gateway control units are identified by the PIWIS Tester in the full
control unit list as well as programming and coding screens: the typical Gateway 3.1 control unit and a
new Gateway 3.1 (00x) RxSwin. Where applicable, the Gateway 3.1 (00x) RxSwin indicates an individual Regulation-specific (RXXX) Software Identification Number.
Note for North American Region (NAR) As of this publication, no such regulation-specific software identification number (RxSwin) is handled by the Gateway control unit. Coding errors pertaining to Gateway 3.1
(00X) RxSwin do not indicate an error in the Gateway control unit coding or configuration. Such errors can
typically be ignored if they are not remedied by either running the campaign sequence a second time or
by individually completing Automatic Coding of the Gateway control unit.
Required PIWIS Tester software release:
42.100.060 (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:
E3P1A
Programming sequence:
Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
Do not interrupt programming and coding.
After programming has been carried out, the
result of the programming must be checked
and, in the event of deviations from individual
control units, the corresponding control unit
must be re-programmed or re-coded.
A backup documentation process for the
re-programmed software releases starts once
programming and coding is complete.
Programming time (up to):
•
•
270 minutes
The duration of the programming the control
units depends on the build status and can
differ from the specified time.

Information
If individual programming steps or rework could not be carried out correctly, see Workshop Manual for
the basic procedure for control unit programming using the PIWIS Tester  Workshop Manual '9X00IN
Basic instructions and procedure for control unit programming using the PIWIS Tester - section on “Fault
finding”'
In the event of a fault, logging must always be created during programming using •Ctrl“ and •L“ using
the PIWIS Tester.
As a general rule, if programming is aborted during programming, programming must be continued.
The entire sequence can be started again at any time using the campaign code. The control unit that has
already been programmed is skipped, or programming is started via the integration test. Starting to use
the integration test is faster.
