AKA7 – Checking Control Unit for Air-Conditioning Blower and Replacing it if Necessary (Recall Campaign)

Revision: October 1, 2019

This revision amends AKA7 as follows:

All references to “right hand drive” were removed, Remedial Action was revised, and new scopes were added.

Model Year: 2010 – 2016
Model Line: Panamera (970)
Subject: Control unit for air-conditioning blower
Concern: There is a possibility that moisture can get into the control unit for the air-conditioning blower on the affected vehicles and cause short circuits there.

Depending on how much moisture gets in, this can cause malfunctions and short circuits in the air-conditioning blower control system.

These short circuits can lead to an increased risk of fire.

Remedial Action: Check control unit for air-conditioning blower (blower regulator) and replace it if necessary.


If the interim solution WKE0 has not yet been carried out on a vehicle in addition to this campaign, WKE0 must not be carried out.

On vehicles on which the interim solution was carried out, the blower regulator must be replaced during campaign AKA7 and the relay that was installed temporarily in the electric wire harness must be removed again. There will then no longer be any loss of comfort.

The work required for this must be performed as described underTechnical Information ‘Removing relay for activating control unit for air-conditioning blower and replacing blower regulator’.

For warranty processing for both campaigns, proceed as follows in this case:

  • Mark campaign WKE0 as Recall Update with the reason “Other” in PQIS. The “Warranty relevance” flag must be activated in order to be able to set a warranty claim and close the campaign.
  • A warranty claim must be submitted for campaign WKE0 in which 0 TU is entered as the specified working time and no material items are specified.
  • Invoice campaign AKA7 in the usual way using a regular warranty claim as described under ⇒ Technical Information ‘Warranty processing’.
Affected Vehicles: Only the vehicles assigned to the campaign (see also PCSS Vehicle Information).
Installation position: Installation position of control unit for air-conditioning blower
