Symptom - Engine - Hard Gear Changes: Re-programming (Tiptronic) Transmission Control
Unit (SY 124/17)
Model Line:
Cayenne (92A)
Panamera S E-Hybrid (970)
Model Year:
As of 2015
Equipment:
8-speed automatic transmission for all-wheel drive (G1G, Tiptronic)
Subject:
Tiptronic and DME control unit
Symptom:
Hard or jerky gear changes.
Cause:
This is caused by the transition phase when changing from the engaged gear to the target gear.
Various components of the powertrain affect the shifting quality.
Remedial
Action:
In the event of a customer complaint, use PIWIS Tester III with software 36.400.020 (or higher) installed
to:
•
•
re-program and code the Tiptronic control unit via "Automatic programming" and
reset the adaptation values.
Information
The customer must be informed that:
Tools:
•
The gearshift behavior or shifting quality is temporarily impaired due to the reset adaptation values.
•
This process depends on technical factors and re-adapts according to the customer's
handling/driving style.
9900 - PIWIS Tester III with PIWIS Tester software version 36.400.040 (or higher) installed
Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of 90A
fixed voltage 13.5V to 14.5V.
Work
Procedure:
NOTICE
Coding will be aborted in the event of low voltage.
•
Increased current draw during diagnosis can cause a drop in voltage, which can result in one or more fault
entries and the abnormal termination of the coding process.

Technical Information
Before commencing work, connect a suitable battery charge or power supply - suitable for AGM Type
batteries, recommended current rating of 90A fixed voltage 13.5V to 14.5V to the jump-start terminals in
the engine compartment.
NOTICE
Coding will be aborted if the Internet connection is unstable.
•
An unstable Internet connection can interrupt communication between PIWIS Tester III and the vehicle
communication module (VCI). As a result, coding may be aborted.

During control unit coding, always connect PIWIS Tester III to the vehicle communication module (VCI) via
the USB cable.
Information
The procedure described here is based on the PIWIS Tester III software version 36.400.040.
The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the
instructions that must be followed.
A discrepancy may arise with later software versions for example.

Preliminary work:
1.1
Connect a battery charger/power supply with a current rating of at least 90 A.
1.2
Switch on the ignition using the original driver's key. On vehicles with “Porsche Entry &
Drive”, do this by replacing the control unit in the ignition lock with the original driver's key if
necessary.
1.3
9900 - PIWIS Tester III with software version 36.400.040 (or higher) installed must be
connected to the vehicle before starting it.
