Model Year:

As of 2017 up to 2018

Vehicle Type:

718 Boxster / 718 Cayman (982)

The red warning message “Refill coolant immediately _ Stop driving” can appear at times in the

Cause:

Remedial
Action:

The connector between the vehicle wiring harness and coolant reservoir may not be connected correctly
and, as a result, the electric plug connection on the coolant reservoir may not be locked correctly.

Information
In the event of a complaint and if the plug connection is loose, the electric plug connection must be
connected correctly and secured using the repair kit (00004330676). The repair kit installs an
additional retaining clip on the electric plug connection, to ensure the electric plug connection remains
securely connected.
 It is not enough to just re-connect the electric plug connection to the existing coolant
reservoir. The repair kit must be used after re-connecting the plug, to ensure that the plug
remains secure.

Date of
Introduction:

An adapted coolant reservoir has been installed as standard since 10 April 2018 or starting with vehicle
identification number WP0CA2982JS212001.
Vehicles with the adapted coolant reservoir (vehicle production date 10 April 2018 or later) do not require
the use of the repair kit.
