Model Year:

As of 2014 up to 2016

Vehicle Type:

Panamera S E-Hybrid (970)

Subject:

High-voltage battery

Information:

Modified procedure for high-voltage battery replacement
•

From now on, if the high-voltage battery of the Panamera S E-Hybrid (970) needs to be replaced, the
high-voltage battery of the Cayenne S E-Hybrid (92A) will no longer be used.

•

Panamera batteries will be provided by our local remanufacturing partner: Spiers New Technologies.

•

The previous Technical Information, Group 2, No. 88/19, which describes the procedure for using
the high-voltage battery of the Cayenne S E-Hybrid (92A) in the Panamera S E-Hybrid (970), is
therefore no longer valid and has been removed from the Porsche Central Service System (PCSS).
The Electronic Parts Catalogue (PET) has also been updated accordingly.

Information
HV battery replacement is under the Approval and Support Management process and procedures should
be followed.
Remedial
Action:

Various repair concepts are available for the high-voltage battery, depending on the respective market.
You will find the repair concept for your specific market and the relevant procedure for rectifying faults on
the high-voltage battery in the  Technical Information 'Replacement of high-voltage battery' section.

Replacing the high-voltage battery
Work
Procedure:

The following repair concepts are currently available for the high-voltage battery:
•

USA (PCNA): Coordinate approval for a replacement high-voltage battery with Technical Support
of the PCNA, who will then assume responsibility for procuring the battery from Spiers Inc., see 
Technical Information 'Procedure - USA (PCNA)'. Then return the old battery to Spiers Inc.

Following control unit programming, the software
version can be read out of the relevant control unit in
the 'Extended identifications' menu using the PIWIS
Tester.

 Workshop Manual '9X00IN Basic instructions and
procedure for control unit programming using the
PIWIS Tester - section on "Fault finding"'.

Information
Once the high-voltage battery control unit has been re-programmed, a diagnosis of the high-voltage
battery is performed the next time the BUS is idle (ignition is switched off and the vehicle is locked). This
process must not be interrupted. If the diagnosis is aborted because the vehicle was locked while the
diagnosis was running, for example, a fault memory is stored.
