Pay particular attention to the following:
•

For this PCM software update, the USB storage medium USB Type A+C 32 GB with the part number
V04014999WW000 must be used.

•

To use the software tool, one blank or re-writable USB storage medium is required for each individual software.

•

The software available in PiUS must only be used in accordance with the instructions provided in a
Technical Information published for this purpose.

The software mentioned here must only be used on the vehicles assigned to the campaign. Damage
to the central computer cannot be ruled out if the software is used on other vehicles.

Additional instructions if programming is aborted
Information
If individual programming steps or reworking 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 - chapter on “Troubleshooting”'. :
In the event of a fault, logging must always be created during programming using •Ctrl“ and •L“ using
the PIWIS Tester.
Porsche AG programmed approx. 100 vehicles before the campaign was published as part of an internal
pilot project; not one single control unit had to be replaced in the vehicles.
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.
You will also find further information and instructions specifically for the VR19.0.1 update in the table
below:
