Information:

Retrofitting
Information
ONLY for markets in which new vehicles are certified in accordance with the Worldwide Harmonized Light
Vehicles Test Procedure (WLTP): Retrofitting of components BEFORE the date of first registration of the
vehicle is not permitted.
Background:
Technical modifications (additions/conversions) between delivery (reference point for the creation of the
Certificate of Conformity (CoC document)) and the time of first registration can jeopardize the consistency
between the CoC document and the actual vehicle configuration required by the WLTP.

Model Year:

As of 2025

Restriction:

Not for vehicles with I-no. 8VP (light panel with black “PORSCHE” logo)

Enabling:

For vehicles with I-number 8VG, an enabling code for the animation must be requested via the ordering
process shown in the table. This process is necessary for ordering parts, as this takes a few days.

I

Requesting enabling codes (directly via the Porsche Request
Management System – PRMS => Parts Support => Tequipment/
TEQ-activation Code)
The following details are absolutely essential:


Part number of the retrofit kit
Vehicle identification number (VIN) of the vehicle to be
converted
Order number used for ordering parts

IMPORTANT: If you do not have the necessary data or if the data
you have is incorrect, Porsche AG will NOT be able to generate
the enabling code.
II

Checking and forwarding of the data via PRMS

III

Generation of an enabling code and feedback via PRMS
