WC43 - Replacing Electric Change-over Valves (Workshop Campaign)
Vehicle Type:
911 Carrera (991)/911 Carrera S (991)
Model Year:
As of 2012 up to 2013
Revisions:
Revision 1 – November 2, 2012;
1. Amends the table on Page 2, i.e., items 7 and 8 have been reversed.
2. Amends text for Items 7 and 8 by reversing their order.
Revision 2 – November 29, 2012 Additional information note added to page 4 with illustration
“Change-over valve new/old”.
Concerns:
Electric change-over valves
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is the
possibility that electric change-over valves, which may be susceptible to the ingress of moisture due
to insufficient sealing, were installed in the affected vehicles. This can cause the change-over valves to
malfunction over time.
As a result, control over the closing valves in the clutch cooling system (PDK) and gear wheel set (PDK
and manual transmission) may be impaired.
In extreme driving situations (e.g. race starts, high ambient temperature, frequent gear changes), the
transmission or clutch could overheat.
Action
Required:
Replace the electric change-over valves for the gear wheel set heat exchanger and the change-over
valve for the clutch fluid heat exchanger.
Additionally, all thermal management change-over valves of the same design must be replaced in order to
ensure that all valves within the vehicle are of the same type.
Affected
Vehicles:
The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair. This campaign affects 3,718 vehicles in North America.
Parts Info:
NOTE: DO NOT ORDER PARTS FOR THIS CAMPAIGN. THEY WILL BE AUTOMATICALLY
ALLOCATED TO YOUR DEALERSHIP.
