Information
Depending on whether or not the previous software version VR8.7 must first be programmed on the
relevant vehicle before programming software version VR12.1.1, the vehicles were assigned to the
required campaign scope. Before carrying out the campaign, the campaign scope assigned to the
relevant vehicle must therefore be checked and carried out accordingly.

Risk of damage to components
Do not reach into the danger area.
Keep third parties away from the danger area.
Do not move components or tools into the danger area.
Work Procedure: 1
Select the guest account from the central display (PCM) and activate Privacy mode (available in
some countries).
Information
To ensure that no user-specific settings from cloud-based services (Porsche Connect & My
Porsche) are lost during the update, activate Privacy mode before starting the update. When Privacy
mode is activated, communication between the vehicle and the Porsche Connect app and My Porsche is
disabled. No vehicle-specific information is transferred. As a result, settings cannot be configured on the
vehicle using the Porsche Connect app or My Porsche.
When the instrument cluster and central computer are re-programmed, the individual settings
implemented in the vehicle by the customer will be lost and reset to the default values of the country
version that applies to the vehicle.
After carrying out the campaign, please inform customers that personal settings they have implemented
in the instrument cluster and central display of the central computer will have to be set again and provide
them with any help and support they need for setting the relevant options.
