Symptom - Body Exterior - Interior Surveillance Deactivated/SAFE Lock System Does Not
Function: Re-programming Rear-end Electronics Control Unit (SY 129/19)
Model Line:
Panamera (971)
Model Year:
As of 2017 up to 2020
Subject:
Control unit for rear-end electronics
Symptom:
Interior surveillance is deactivated and SAFE lock system does not function. The hazard warning lights
give one long flash when locking and the Save LED in the door lights up for approx. 30 seconds.
Cause:
Due to a software error, the fault memory entries "B133029 - Interior surveillance sensors – signal
implausible" and "B131D29 - Alarm siren – signal implausible" can be stored at times. As a result, the
described symptoms occur.
Remedial
Action:
In the event of a customer complaint and if the software version is "0367" or "0387", the rear-end electronics control unit must be re-programmed and coded.
Information
The total time required for control unit programming is approx. 8 minutes.

Introduction:
New software version "0424" used from:
Date
19.06.2019
VIN
WP0ZZZ97ZLL192003
Required tools
Tools:
•
•
9900 - PIWIS Tester 3 with installed PIWIS Tester software version 38.800.010 (or higher)
Battery charger with a current rating of at least 90 A, e.g. VAS 5908 - Battery charger 90A.
Preparatory work
NOTICE
Fault entry in the fault memory and control unit programming aborted due to low-voltage.
•
Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which
can result in one or more fault entries and the abnormal termination of the programming process.

Before getting started, connect a suitable battery charger with a current rating of at least 90 A to the
jump-start terminals.

NOTICE
Control unit coding will be aborted if the WiFi connection is unstable.
•
An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle
communication module (VCI). As a result, coding may be aborted.

During control unit coding, always connect the PIWIS Tester to the vehicle communication module (VCI) via
the USB cable.
NOTICE
Control unit coding will be aborted if the driver's key is not recognized
•
If the driver's key is not recognized in the vehicle, coding cannot be started or will be interrupted.

Place the driver's key with the back facing down into the front left storage compartment in the center
