ASA3 – Re-Program Reversing Camera Control Unit and, if necessary, Replace Reversing Camera and
Surround View Cameras (Recall Campaign)
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.

Update of Warranty processing
Update of labor time for scope 1 and 2
Model Year:
As of 2024 up to 2026
Model Line:
Macan Electric (XAB)
Equipment:
Front and rear ParkAssist assistance systems incl. reversing camera (M-no. KA2)
or
ParkAssist assistance systems incl. Surround View (M-No. KA4)
Concerns:
Reversing camera control unit
Surround view camera
Cause:
In rare cases, the reversing camera of the affected vehicles cannot be activated when ParkAssist is
switched on due to a software error. In addition, with a very small number of affected vehicles, it is
possible that the housing of the reversing camera and individual surround view cameras in the surround
view equipment option were not bonded as per default value specifications.
As a result, no camera image is displayed in the central display when ParkAssist is activated contrary to the
default value specifications. If the camera housing is not bonded correctly, moisture can penetrate and impair
the camera image.
Action:
Re-program reversing camera control unit using the PIWIS Tester and replace reversing camera and individual surround view cameras if necessary.

Information
Vehicle update – general information
The entire vehicle network will be checked for a necessary update or computed to ensure fault-free functioning of the vehicle. For this purpose, the following preparations are to be made:
•
Latest release on PIWIS Tester 4 and PiUS available
•
Vehicle is fully built up
•

•
The user must be logged in to the PIWIS Tester 4 in the PPN
•
Vehicle must be supported with an external charger
•
Seat heating and seat ventilation are not active
•
Place the original hand-held transmitter in the emergency start tray (see Workshop Manual)
The vehicle performs the update independently. The current status can be retrieved on the diagnostic tester
or on the front display and control panel (R238) under Messages (RPC+).
Information
The entire update process for this action takes approx. 5 minutes.
However, the download speed of the update package depends on the performance of the local network and
can vary accordingly.
