WKE0 - Retrofitting Relay for Activating Control Unit for Air-Conditioning Blower (Workshop
Campaign)
Model line:

Panamera (970)

Model Year:

As of 2010 up to 2016

Subject:

Control unit for air-conditioning blower

Information:

Optimized control units for the air-conditioning blower that are needed as part of campaign
AKA7 are currently not available yet in the quantity required for retrofitting all affected
vehicles immediately.
To remedy this situation immediately, an interim measure is required.

Remedial
Action:

As part of the interim measure, the previously installed blower regulator must be additionally sealed
using a sealing cord, thereby preventing further moisture from seeping in. An additional relay will also
be installed in the electric wire harness for the blower regulator. This will interrupt the power supply for
the blower regulator immediately after switching off the ignition, thereby ruling out the possibility of short
circuits in the blower regulator when the vehicle is parked.

Customer is contacted by PCNA via first class mail that Recall AKA7 is open on their vehicle and to
contact their nearest dealer to carry out the recall..
PCNA has offered to pay for towing the vehicle in for the Recall if the customer is not comfortable
driving the vehicle in themselves. This service is to not be offered unless requested. To arrange
vehicle tow, the dealer should call the dedicated phone number 1-(866)-777-9647 and notify the
agent that they are requesting a tow to the dealer on behalf of the customer for recall AKA7. Please
note that the customer will be responsible for retrieving their vehicle when it is ready.
Customer arranges an appointment with the Porsche dealership for carrying out campaign AKA7.
Once at the Porsche dealership, the blower regulator part number in the vehicle will be
checked as outlined in campaign AKA7.
If the result of the part number check is OK (blower regulator does not have to be replaced),
the measure is complete and warranty invoicing is performed using the campaign number AKA7
under campaign scope 1. After carrying out campaign AKA7, campaign WKE0 must be closed by
performing a recall update (warranty claim with 0 material units and 0 time units).
If the blower regulator has to be replaced, this interim measure WKE0 must be carried out
for as long as required until optimized blower regulators are available.

As a procedural safeguard and for control purposes, this measure will involve a two-fold implementation. This means that if the result of the part number check is not OK, all required tasks (checking
and reworking blower regulator and installing relay) will be implemented by carrying out workshop
campaign WKE0 and the status of recall campaign AKA7 will only be set to complete when the
optimized blower regulator has been installed in the vehicle.
