APA1 - Replacing Additional Pump (Stop Delivery / Recall Campaign)
Model Line:
Panamera (971)
Model Year:
As of 2017 up to 2021
Concerns:
Additional pump for air conditioning control
Information:
On the affected vehicles, there is a possibility of moisture getting into the control unit for the
additional pump of the climate control system and causing malfunctions in the temperature
control of the interior and when the engine residual heat function is activated.
Over the service life of the vehicles, such malfunctions can lead to short circuits and promote visible
damage to the additional pump successively to the plug connection of the wiring harness. As damage
progresses, an unnoticed short circuit can lead to an increased risk of scorching and even fire.
Activating the AUTO-REST button in the center console can cause fire damage even longer after stopping
the vehicle.
Action required: Replace additional pump for air conditioning control and check plug connection and replace if necessary.
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
